Why the Waist-to-Height Ratio (WHtR) is an Indicator of Obesity and Overall Health

There is a ratio called the Waist-to-Height Ratio (WHtR) that is used as an indicator of obesity and overall health. It is calculated by dividing your waist circumference by your height. The WHtR is considered to be a better indicator of health risks associated with obesity than the more commonly used body mass index (BMI) in some cases.

The problem with BMI is that it ignores muscle mass and bone density, by which standard even Arnold Schwarzenegger in his prime would have been considered obese because of the added muscle and bone weight. Thus BMI isn't actually a good indicator of obesity.

The Waist-to-Height Ratio (WHtR) however is a good indicator.

To calculate your waist-to-height ratio, follow these steps:

1. Measure your waist circumference: Use a measuring tape to measure the circumference of your waist at the narrowest point, typically around the belly button.

2. Measure your height: Use a measuring tape or a wall-mounted height scale to measure your height in either centimeters (cm) or meters (m).

3. Divide your waist circumference by your height: Divide your waist circumference by your height. Make sure to use the same units for both measurements (e.g., if your waist circumference is in centimeters, convert your height to centimeters as well).

For example, if your waist circumference is 80 cm and your height is 170 cm, the calculation would be: 80 cm / 170 cm = 0.47.

The resulting number is your waist-to-height ratio. The general guideline is that a ratio below 0.5 is considered healthy, while a ratio above 0.5 indicates an increased risk of health problems associated with obesity.

Note that having a lot of abdominal muscles (eg. a robust six pack) could also skew the results of the WHtR, but this would be an extreme rarity. Likewise someone who is pregnant should ignore their waist-to-height ratio.

It's important to note that while the waist-to-height ratio can be a useful tool, it is not the sole determinant of obesity or health. Other factors, such as body composition, muscle mass, and overall lifestyle, should also be taken into consideration. It's always a good idea to consult with a healthcare professional for a comprehensive assessment of your health.

What about Anorexia?

The waist-to-height ratio (WHtR) is generally not used as an indicator of anorexia. Anorexia nervosa is an eating disorder characterized by an intense fear of gaining weight, distorted body image, and extreme weight loss. While weight loss and low body weight are common features of anorexia, the WHtR is not typically used to diagnose or indicate this condition.

In diagnosing anorexia nervosa, healthcare professionals typically consider a range of factors, including body weight, body mass index (BMI), psychological symptoms, and other physical and behavioral indicators.

BMI is often used as a screening tool to assess weight status and potential health risks associated with weight, but it is important to note that BMI alone cannot provide a comprehensive diagnosis of anorexia or any other eating disorder.

If you or someone you know is concerned about anorexia or any other eating disorder, it is essential to seek professional help from a healthcare provider or a mental health specialist who can conduct a thorough evaluation and provide appropriate guidance and treatment.

How do Cold Showers Burn Calories?

Cold showers don't directly burn calories, obviously, but there is an indirect causal effect that leads to the burning of calories.

If you read the old blog post Cold Showers Burn Calories we go into the reasons why a little bit, but it is past time that we explain in more detail.

When exposed to cold temperatures, the body triggers thermogenesis, a process in which it generates heat to maintain its core temperature. This thermogenesis can be achieved through two main mechanisms:

Shivering

When the body experiences cold, shivering is one way it generates heat. Shivering involves rapid muscle contractions that generate heat as a byproduct. While shivering may slightly increase calorie expenditure, the overall impact on weight loss is minimal.

Brown fat activation

Cold exposure may activate a type of fat tissue called brown adipose tissue (BAT) or brown fat. Unlike white fat, which stores energy, brown fat is specialized in generating heat through a process called thermogenesis. The activation of brown fat is associated with increased energy expenditure, as it burns calories to produce heat. However, the amount of brown fat in adults is relatively small compared to other tissues, and its overall contribution to calorie burning is not yet fully understood.

The amount of fat/calories that gets burned per shower isn't a lot, although it does vary upon the size of the person, and the cumulative effect of daily cold showers over the course of a year is actually significant.

How many calories are burned?

Honestly, it varies upon the person, how cold the water is, and what methods people use to try and calculate the amount of calories burned.

Here's a conservative estimate of how many calories are burned:

The additional calories burned during a 10-minute cold shower for a 100 kg person would range approximately from 20 to 30 calories. So roughly 25 calories.

It isn't a lot, but if the person had daily showers over the course of a year then they would burn roughly 2 to 3 extra pounds of fat per year.

Over a 10 year period that could be a difference of 20 to 30 lbs.

But remember that is a conservative estimate for a person who weighs 100 kg (220 lbs).

There's also an argument that a thin person would actually burn more calories in a cold shower than an overweight person, because they have less body fat to insulate themselves from the cold. So the number of calories being burned could be inversely connected the percentage of body fat a person has.

Thus someone who weighs perhaps 50 kg (110 lbs) with only 12.5% body fat might actually be burning two or more times the amount of fat by having cold showers than someone who weighs 100 kg (and has perhaps 25% body fat or more) because they are more easily made colder due to a comparative lack of insulation. Thus people who are already thin could potentially prevent themselves from gaining weight by having cold showers regularly.

But it also means that someone who is losing weight would encounter a case of "increasing caloric burn" as they continue to shed body fat, thus seeing a gradual acceleration of weight loss over the long term.

Conclusions?

Cold Showers + Healthy Diet + Exercise = Pretty much guaranteed to lose a lot of weight quickly, and over the long term see the health benefits. The real trick in that situation is to stay motivated. Not everyone wants to have cold showers ever day, eat healthy all the time, and exercise daily.

So what you really need is cheat days:

That 1 day of the week where you allow yourself (as a treat) to have a hot shower.

A high carbs day where you're allowed to eat as much as you want.

A day of relaxation when you can just chill and don't have to exercise.

Having cheat days, combined with tracking your weight/counting calories, are just two ways to stay motivated and keep going.

Is traditional archery the same as instinctive archery? Nope.

Q

"Hi Charles,
Is what we did last class considered instinctive shooting, since we didn't use sights?
D."

A

Hey D!

That would a misnomer to call traditional aiming/style the same thing as instinctive. The two things are very different.

Unfortunately there is a lot of confusion/misinformation about what instinctive aiming / instinctive style is (Lars Anderson is not helping either, his videos are full of misinformation), and this is not the first time I have had to explain the difference. Compound Shooters and Olympic Shooters have an awful habit of looking at traditional style and thinking that it is instinctive, but they don't know that there is an aiming methodology to what the traditional archer is doing, and that there is a specific form.

Traditional Aiming - Aiming off the tip of the arrowhead.

Gap Shooting - Aiming using the gap between the side of the bow and the target, using memory to remember where to aim. Sort of like an imaginary sight.

Aiming with Sights - A gadget commonly used by Olympic and Compound shooters that tells them where to aim.

Instinctive Aiming - Not really aiming, but rather just "shooting from the hip" using "gut instinct", like you might see in a Western quick draw duel.

Traditional Recurve Style - Following form principles designed to increase accuracy through repetition, muscle memory, stable footing/form, consistent back power, etc.

Olympic Recurve Style - Very similar to Traditional Recurve Style, but with several changes to take full advantage of gadgets commonly used in Olympic archery.

Compound Style - Form wise it appears similar to the other two, but compound shooters are less worried about form as the gadgets on the typical modern compound bow basically allow a complete beginner to shoot with a remarkable amount of accuracy with little to no knowledge about how form could improve their accuracy.

Howard Hill Style - Commonly used by longbowmen and some traditional recurve shooters, the Howard Hill Style is similar to Traditional Recurve Style and is for archers who prefer to cant their bow while shooting. (You saw me demonstrating this style on Sunday with my 1972 Black Hawk Avenger bow, although with the aided flair of me kneeling during the shots.)

English Longbow Style - No canting, often involves aiming to the side a bit. In the case of an English Warbow there is a different method of holding the bowstring and releasing.

Horseman Style - Nearly identical to the Howard Hill Style, but with a Horseman's Release and/or a Thumb Ring. Often with a much more profound cant on the bow.

Instinctive Style - Formless. Just pull back any which way and shoot. No form needed. So for example if I lifted one leg and pulled the bowstring back underneath my leg (like a showoff would) and then shot, that would count as instinctive shooting. Pull back the bow from behind my back, over my head, partial draw, overdrawing way off to the side, etc - that would all be instinctive. The downside of this formless style is that the archer is really just guessing where the arrow will go. With practice they get better at guessing, but it is really only remotely accurate at very close distances. Any mid to long range distance and instinctive style/aiming is useless.

Little kids who have never done archery before basically shoot instinctively.

What I prefer to teach is ALL the different methodologies of shooting, starting with traditional and progressing in the directions the student is more interested in. If they later want to learn how to use sights, I will teach them how to use sights. If they want to learn Horseman Style, a horseman's release, etc - then I will steer the teaching in that direction. If they express an interest in longbows, then I will typically teach them the Howard Hill Style and show the differences between English Longbow and Howard Hill style. Thus if they want to learn multiple styles, I will teach them multiple styles.

So what you did on Sunday was:

• Traditional Aiming.
• Traditional Recurve Style.
• Field Archery - In terms of what you were aiming at and the random distances. As opposed to say "Target Archery", "Flight Archery", "Clout Shooting", "Popinjay"... "3D Shooting" would be pretty similar to Field Archery, but would often involve shooting uphill or downhill.

If you want to learn more about Instinctive Style during lessons let me know and I shall demonstrate some shots and you can try it out too to see how you like the formless style of shooting.

(I decided to use this question and answer for an article on my website. I will list your name as "D." for privacy's sake.)

Does Walking really count as Exercise?

I think it is silly to be even be talking about this, but apparently there are some people out who think walking doesn't really count as exercise - because walking is something you do every day anyway.

However as an avid walker - someone who comes back from long walks/hikes feeling exhausted, hungry and yet feeling like I accomplished something - I must defend walking not only as an exercise, but as a great way to build up an appetite.

Exercise does NOT have to involve:

• Sweating
• Grunting
• Gasping for breath

Some exercises do, obviously, but it is definitely not a requirement. Anyone who tells you that exercises have to make you feel out of breath clearly has some funny notions about what counts as exercise.

So while we are at it, lets bust some myths people might have about walking by laying down some facts about walking.

Fact #1. Brisk Walking is actually a Moderate-Intensity Aerobic Exercise

Walking at a brisk pace that raises your heart rate into the moderate-intensity zone is recommended for the benefits of so-called "real exercise" for the cardiovascular system and to reduce health risks.

However even a slower pace counts as a Light or Lower Intensity workout. More so if there is  hill climbing or stairs involved.

A brisk pace is one where you are breathing harder than normal - you can talk, but you can't sing. If you take your pulse, it should be between 50 percent and 70 percent of your maximum heart rate. Walk at least 10 minutes in this zone for it to count as a moderate-intensity exercise session. You should aim for a minimum of 30 minutes of moderate-intensity exercise per day, five days per week, which can be broken up into sessions of at least 10 minutes at a time. For beginners try doing 20-minute brisk walks at a time and over time go further distances for longer periods to build up your endurance.

Fact #2. You can build Endurance using Long Distance Walks or Brisk Walking

Going for a longer distance walk (such as a 2 hour hike) will help build your endurance. You can do the same thing using brisk walking, but over a short distance. Brisk Walking for 30 minutes or more, five to seven times per week will build more muscle in your heart and lungs. Aim for a fast walk that brings your heart rate into the zone of 65-75 percent of your maximum heart rate.

If you prefer longer walks / hiking, aim to get your heart rate to reach the 40 to 60 zone.

Fact #3. You can use Walking as Exercise for Weight Loss

The truth about any exercise for weight loss is that it can help keep off extra pounds, but controlling what you eat will have the biggest effect. A healthy low-calorie diet combined with regular exercise - whether it is walking or something more intense - will help you to burn fat and consequently lose weight.

At least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity is great for weight management. But getting exercise only solves half the problem - you also need to watch your eating habits and reduce your calories.

You can't outrun or outwalk what goes into your mouth

Fact #4. There are Health Benefits to Low or Easy-Intensity Walking

Walking the dog or going for a stroll at an easy pace works your muscles and joints. This is especially beneficial if you are overweight, aged, or at risk for arthritis. Strolling at an easy pace reduces the loads on the knee joints by 25 percent while actually burning a few more calories per mile than walking faster - assuming you are going the same distance regardless.

What burns more calories? Walking 100 meters really slowly, or jogging 100 meters?

Walking at a speed of 4 km per hour (average walking speed is 5 kmph) a person can walk 100 meters in exactly 1.5 minutes. A 200 lb person walking 100 meters at this speed burns 6 calories.

Jogging at 10 kmph a person can jog 100 meters in exactly 36 seconds. The same 200 lb person jogging that distance at that speed burns 8 calories.

So going faster only burned 33% more calories, but did it in less than half the time.

Walking slow also doesn't have the cardiovascular benefits of brisk walking (which would have burned 7 calories in the above example), but it is a good starting point for adding activities to your daily schedule that burns more calories.

Fact #5. Low-Intensity Exercises that Break Up Sitting Time reduces Health Risks

Many studies are finding that sitting or simply standing still for more than 30 minutes at a time can raise your health risks, even if you do a full bout of exercise at some point in the day. Walking around for one to three minutes every half hour or hour has been shown to be needed to reduce these health risks.

Getting up and circling the office or house thus can lengthen your life span. One study found that these short, easy walking breaks improved glucose control and insulin response. An increasing number of fitness bands have inactivity alerts to remind you when it's time to get up and move.

And lastly, another study determined that taking breaks from periods of sitting also reduced your stress and improved your sense of well-being, which in turn has an effect on mental health and even boosts your chances at weight loss because depressed people are more likely to overeat.

Fact #6. 10,000 Steps Per Day is a Good Workout

If you are addicted to tracking your daily footsteps and make the effort to reach 10,000 steps per day, does that mean you are exercising? For most people, that number is an indicator you have engaged in exercise during the day, as it is difficult for most people to log more than 6,000 steps just in daily activity. You could log 10,000 steps at an easy pace during the day, and it obviously wouldn't qualify as moderate-intensity exercise, but it would still count as a low-intensity workout.

Many fitness trackers, such as Fitbit, analyze your steps and record those that are aerobic or exercise steps done at a pace they consider fast enough to quality. Thus if you want to ensure you are getting a "real workout" then look at that number as well as the step total.

Fact #7. Race Walking is an Olympic Sport

Walking is a physical activity regardless of what speed you enjoy doing it, from a slow stroll through a fast brisk that is practically jogging. eg. Like competitive walking, aka "Race Walking" - which oddly enough is also an Olympic Sport.



Conclusions

Yes, walking is exercise. Indeed, it is even a sport.

That said, you should balance walking with other physical activities that benefit various parts of your body. Strength training to build and maintain muscle. Cycling is very beneficial for walkers as it works the opposite leg muscles. It is good to engage in a wide variety of activities, so all of your muscle groups are challenged and strengthened. Keep walking and hiking and jogging, whatever it is you do - and remember, you are still exercising.

Amateur Fighters Vs Trained Boxers

March 17th 2017.

When people find out that I like boxing sometimes the topic gets into the idea that amateurs can somehow compete against a trained boxer.

At which point I have to either stifle a laugh or burst out laughing.

The problem lies with the public misconception / myth that boxers are just brawlers and that boxing doesn't require any skill or training. After all, any idiot can throw a punch right?

Yes, any idiot can throw a punch. But are they actually good at throwing a punch? Do their punches connect? How hard do the punches connect? Do they know how to dodge or take a punch?

People who don't know what they are doing typically:

• Regularly miss the target.
• If they do hit, it is often a glancing blow which deals no real damage.
• Don't know anything about footwork.
• Don't know anything about how to fade, block, deflect, etc.
• Don't know how to take a hit.
• Unable to control their emotions, they leave their defenses down.

Trained boxers however:

• Consistently hit the target.
• Rarely deal a glancing blow and hit quite hard in comparison to someone who lacks training.
• Understand how to use footwork to both execute hits and avoid getting hit.
• Knows how to fade, block, deflect, etc.
• Can take their share of hits.
• Very much in control of their emotions, handles themselves with experience.

In the video below you will see an Irish bouncer (who apparently got his job because he is a trained boxer) vs two idiots who think that they have the advantage because of youth. Two young men with no boxing training vs one middle-aged man who knows what he is doing.




Take note of the following:

• The footwork of the bouncer.
• How he avoids confrontation. He plays it safe, and he is also patient.
• How he only punches when he needs to and only when he knows he will connect.
• When he hits, he hits hard. The one idiot gets knocked out cold.

Bonus Boxing Myth Busting Tip

Boxing gloves aren't just to protect the hands of the boxer. They also allow the boxer to hit even harder. Similar to wearing brass knuckles. Get hit by someone using their knuckles and get hit by someone wearing a boxing glove, and you will realize the glove actually hurts more. Unfortunately most people think that boxing gloves hit softer, because they think it is fairly soft. This myth is perpetuated due to ignorance.

In other news, Happy St Patrick's Day!

I am going to spend a chunk of today binge watching the new Netflix show "Iron Fist". I am looking forward to it. (Do you think it is a coincidence they released it on St Patrick's Day?)

Arrow Speed of Compound Bows Vs Recurves, Shooting Longer Distances

Compound bows shoot arrows at over 300 fps (feet per second), compared to recurves which do closer to 200 fps - which gives an archer a significant advantage when it comes to shooting longer distances.

Take for example the following bow: "The 2017 Mathews Halon 32". (I am not endorsing this bow, I am just using it as an example of a fast compound bow.)

The Mathews Halon 32 has a top IBO speed of 350 fps.

The Halon 32 is not alone in this category of high speed compound bows. Here is a brief list of manufacturers (all 2017 models currently available on the market) and their top IBO speeds:

• APA Mamba M34TF - 355 fps
• Bear Legend LS6 - 355 fps
• Xpedition Xplorer SS - 355 fps
• Bowtech Reign - 350 fps
• Hoyt Pro Defiant - 350 fps
• Darton Maverick II - 350 fps
• Obsession  Turmoil - 350 fps
• PSE Evolve - 346 fps
• Bear Moment - 340 fps
• Hoyt Double XL - 340 fps
• Obsession Hemorrhage DE - 340 fps
• PSE Bow Madness Epix - 340 fps
• PSE Carbon Air 34 ECS - 336 fps
• Prime Centergy - 333 fps
• Hoyt Carbon Defiant - 331 fps
• Bear Legend LS4 - 330 fps
• Cabela's Fortitude - 330 fps
• Martin Firecat - 330 fps
• Prime One STXv2 - 325 fps
• Bowtech Fanatic 3.0 - 320 fps
• Mathews Avail - 320 fps
• Mathews Stoke - 314 (youth bow)
• Gearhead T15 Pro -  237 (micro hobby bow)

So immediately what you learn here is that even the smallest compound bows, like the Mathews Stoke youth bow and Gearhead micro bow, still shoot arrows at faster speeds than recurves. Compound Bows (and those people who are big fans of them) are essentially speed freaks.

You also learn that 300 fps is really more of a minimum. As you can see most of the normal adult compound bows are shooting between 320 to 350 fps.

So why does speed matter for shooting longer distances?

The short answer: Longer arcs equals more accuracy.

Arrows arc their way upwards and eventually downwards at longer distances. At short distances arrows arc up (which means the archer has to aim the arrow significantly below the target), at medium distances they begin to arc downwards (which means the archer has to start aiming higher, possibly just below or just above the target - depending on the distance), and at long distances arrows arc dramatically lower.

If the arc is really short (shot from a weak or possibly sluggish bow), the shots lose accuracy because of the slightest change in aim. In comparison a strong / fast bow will shoot arrows with a flatter trajectory, which allows an archer to more easily make aim corrections that rapidly increase their accuracy. They don't have to worry about the arc of the arrow so much, whereas someone shooting a weak / sluggish bow does.

Remember: The faster the arrow is going, the longer the arc is, the more accurate the arrow will be at longer distances due to the archer being able to more easily adjust their aim.

Is there any reasons why you would not want more speed?

Well, there are some pros and cons - depending on what you are shooting for.

The speed of the arrow is directly tied to the amount of kinetic energy being released from the bow (via the bowstring) and into the arrow, propelling it forward at incredible speed.

• The heavier the arrow, the more kinetic energy it can initially store - and the more momentum and power it retains when it finally hits the target. This makes heavier arrows better for hunting purposes.
• Lighter arrows, although they store less energy, go faster because they weigh less - but at the expense of hitting a target with less kinetic momentum. This makes lighter arrows better for competitive because they want more speed for the purposes of long distance accuracy.

Why would someone choose to use a recurve bow instead of a compound bow?

I shall answer this with a question:

Why would someone choose to use a bow instead of a rifle?

Obviously they have their reasons. Each person might have a slightly different reason.

Thus it really comes down to Personal Preference. People can still get pretty impressive accuracy with a traditional bow - even at long distances.

• Some people find compound bows to be boring.
• Some people find compound bows to be ugly.
• Some people like the challenge of shooting something more traditional.
• Some people like the tradition and history of shooting recurve bows, longbows, horsebows, etc.
• Some people find wooden bows are more visually appealing.
• Some people like making their own bows and thus shooting a "self-bow".
• Some people are drawn to a particular style of archery, such as horseback archery.

Do arrows slow down significantly before they hit a target?

Not by much. It is a common myth that arrows slow down significantly while flying through the air and before hitting the target. Such myths are due to a common misunderstanding about the physics of speed, air resistance, wind, and gravity.

Air resistance and wind has comparatively little effect on the arrow. The big thing is gravity, and that only pulls the arrow downwards. It does not stop forward momentum.

Also an arrow doesn't come to a full stop until AFTER it hits a target. Until it does so, it is still going at a significant speed.

While an arrow is arcing up it still has plenty of forward momentum. That momentum is effectively separate from the power of gravity pulling it downwards. If there was nothing in the way (targets, ground, etc) it would just keep going forward until it lost all of its forward momentum.

There is really only one exception to this:

If you shot an arrow almost straight up it would eventually slow down its vertical climb due to gravity and then start falling - and then pick up speed due to gravity. Thus it did eventually slow down to a speed of almost zero at the top of its zenith, it is always still in motion because it immediately begins its downward ascent and picking up speed again. In theory an arrow could go up, reach its zenith, and then come back down and hit the ground at a speed that was greater than what it was originally shot at - this is because gravity would cause the arrow to accelerate on its downward ascent.

Think of an army of bowmen shooting arrows at an enemy on a distant hill. They aim at the sky, and shoot all their arrows at once in a single volley. The arrows go up, reach their zenith and come back down. They still lots of forward momentum - and they could actually end up going faster due to gravity causing the arrows to accelerate during the downwards arc. Thus when they hit the enemy those arrows are still flying at very impressive and deadly speeds.

And just to able to reach that distance the arrows need to be traveling at a good speed to begin with, which implies that they should be shot from fast / powerful bows.

At the Toronto Archery Range we have a variety of targets people can shoot at ranging from approx. 20 yards to 75 yards (60 feet to 225 feet respectively).

• An arrow shot at a speed of 200 fps reaches the 20 yard target in a mere 0.3 of a second.
• An arrow shot at a speed of 200 fps reaches the 75 yard target in 1.125 seconds.

In theory arrows lose a bit of its speed before they reach 20 yards, and a bit more before reaching 75 yard target, but the distance is still for both is still so short that it is barely worth mentioning. Even at 75 yards, the arrow is probably still doing at least 190 fps at the moment it hits.

For comparison purposes:

• A compound bow shooting an arrow at a speed of 350 fps reaches the 20 yard target in 0.1714 of a second.
• A compound bow shooting an arrow at a speed of 350 fps reaches the 75 yard target in 0.6429 of a second.

And again, the arrows do technically slow down a bit by the time they reach those distances - but the difference is negligible. Guaranteed the arrow is still doing at least 345 fps by the time it reaches 75 yards.

At extreme distances (250 meters or more) you might start notice a larger decline in arrow speed, but the forward arc will still continue until it hits something that gets in its path. A high speed arrow would have to be shot extremely far away (with no obstacles in its way) for it to completely run out of its forward momentum.

How does Newton's Three Laws of Motions apply to Archery?

Newton's First Law of Motion: An object remains at rest/at a constant velocity unless it experiences an unbalanced force.

You may have heard this one before. An object in motion (in this case an arrow) remains in motion until acted upon by an equal or greater force. Thus the arrow keeps its forward motion until it hits an object capable of halting its forward momentum. Air resistance really accounts for a tiny fraction of slowing down an arrow's speed.

When a person pulls back a bow they are storing kinetic energy in the limbs of the bow. When they release the bow, some of that kinetic energy is transferred via the bowstring into the arrow, which propels it forward. Once the arrow is in the air, it meets resistance from air resistance, its trajectory can be modified by wind conditions, and gravity will pull it downwards. However the arrow doesn't stop until it meets resistance sufficient to stop it completely - such as puncturing a target. (eg. See the arrows below sticking out the back of a target.)

Newton's Second Law of Motion: F=ma. Force (measured in Newtons) equals the mass multiplied by acceleration.

The archer applies force when pulling back the bow. That energy is then released as the bowstring goes forward, which accelerates forward past its original brace height. The arrow doesn't leave the bowstring until the bowstring rebounds back to its normal brace height. Once it leaves the bow, the arrows ceases acceleration and has a speed - which remains at a constant until acted upon by Newton's First Law of Motion.

The bigger the arrow (in terms of weight/mass) the larger the force it stores during the initial release. Heavier arrows hit harder. Lighter arrows go faster because they were able to accelerate faster during the initial release of the bowstring, but consequently also store less energy.

Newton's Third Law of Motion: For every action force, there's an opposite and equal reaction force.

When the bowstring is pulled back that is the action, the reaction is the arrow springing forward from spring force of the bow limbs. Some of the energy released also goes into the bow's limbs and causes vibrations - which can effect the accuracy of the shot. This is why some archers shoot to use things like dampeners (which also reduce the sound of the bowstring), limb savers (which reduce vibration in the limbs), and stabilizers (which reduces vibration in the riser, while simultaneously making the bow bottom heavy so it is less likely to be canted left or right by the archer).

Final Thoughts

Physical Benefits of Exercising While Pregnant

#1. Expectant mothers who exercise are less likely to have unplanned c-sections

More and more mothers are being diagnosed with gestational diabetes, which can lead to your baby growing too large. In this case, your baby may be too hard to deliver, requiring a cesarean delivery (11). Moms who exercise during their pregnancy are less like to have unplanned c-sections (12).

#2. Running while pregnant is a great way to boost your heart

If you’re fit and your baby is healthy, it’s perfectly okay for you to continue your normal routine up until your final trimester—it's a great way to boost your heart (2, 5). Expectant mothers who are new to running should start slower and build up to running. Don’t overdo it too quickly, and be sure always to listen to what your body is telling you.

#3. Weight training during your first trimester will help prepare your body for the added weight of your baby

Studies from the Journal of Physical Activity and Health reports low to moderate training twice a week is safe and effective for pregnant women—and weight training during your first trimester can help prepare your body for your baby's added weight (6).

#4. During your first trimester, you can try riding a bike for a healthy way to increase your heart rate

Once you enter your second trimester, your balance may not be what it used to be. At this time you may want to consider switching your bike out with a stationary bicycle, which is a healthy way to increase your heart rate (9).

#5. Doing Pilates can help you with balance issues associated with pregnancy

Pilates focuses on building core muscles and challenging your strength and balance. When you become pregnant, your body begins to produce higher levels of relaxin, which softens the ligaments in your pelvis to make room for your growing baby (7).

This relaxing circulates throughout your entire body, not just your pelvis which can lead to wobbly hips, knees, and ankles. Over time you will learn what your body is capable of and how to control your balance (6).

#6. Activities such as yoga can help reduce blood pressure

High blood pressure is common in pregnant women and even up to 20 weeks after delivery. High blood pressure can decrease the blood flow to the placenta (8), and your baby may receive less oxygen and fewer nutrients if you are diagnosed with high blood pressure. Doing a little yoga during your pregnancy can help to reduce your blood pressure (6).

#7. Exercising throughout your pregnancy can lead to a faster, easier labor

Strengthening your abdominal area, core, and pelvic floor can aid in speeding up both labor and delivery (1, 2). The average first-time mom has a labor of 12-14 hours (3)—cutting this time down will lead to a happier, healthier mother and child.

#8. Exercising during pregnancy can help tame your lower-back pain

Pregnancy related back pain is a common complaint in pregnant women. The added strain caused by your baby bump can have a negative impact on your quality of life.

It's estimated that 50 percent of women will suffer from lower back pain due to pregnancy. Of those women, one-third will experience severe pain (13).

Doing low-impact weight training or stretching exercises such as yoga can significantly help lessen your pain (1).

#9. Regular exercise can prevent pregnancy complications such as gestational diabetes

If untreated, gestational diabetes can deliver excessive sugar to your baby’s bloodstream, which can cause potentially serious complications for both you and your unborn child (12).

Doing regular exercise during your pregnancy can help prevent this (11).

#10. Pregnant women who exercise have improved circulation and blood flow

You can increase your circulation and blood flow by doing consistent exercise (14).

This will allow your baby to receive nutrients it needs more efficiently. Better circulation also helps prevent constipation, varicose veins, and leg cramps.

#11. Women who exercise often will feel less pain from symptoms of pregnancy

By strengthening your muscles, you are essentially giving your body the ability to cope with aches and pains associated with being pregnant (17).

To relieve back pain, try exercises that involve stretching such as yoga. If you are suffering from abdominal pain, try swimming.

#12. You'll notice less swelling of your legs and ankles once you start exercising

Swelling of the legs is common in pregnant women, but increasing your circulation will help calm this swelling. Walking helps increase this circulation by pushing excess fluid in your legs through blood valves and back to the heart (18).

Check out this YouTube video for some great ways to start incorporating exercise into your pregnancy.

Emotional Benefits of Exercising While Pregnant

#13. Light to moderate exercise can give you a better self-image

A lot of women struggle with the changes to their body goes through while they're pregnant, but exercise can help you feel more comfortable by making you feel more in control (14).

#14. Regular exercise can help curb mood swings

Exercise releases endorphins that trigger a positive feeling in the body, making you feel good (9).

Start with 10 minutes of light exercise a day and add more based on how you feel, both physically and mentally.

#15. Doing daily exercises will help boost your energy levels

After exercising, you will begin to feel more motivated to do other activities as well, improving your mood.Staying active also keeps you from becoming restless and anxious (16, 17).

#16. Exercise can give you an overwhelming sense of accomplishment while pregnant

The things you can do while you're pregnant are sometimes limited, but exercising during pregnancy doesn’t have to be one of those things.

Enjoy the satisfaction of completing a task such as a yoga class or a morning jog.

#17. Light exercise throughout the day can help combat fatigue and give you a better night’s rest

Even if you never exercised previous to your pregnancy, you may want to consider taking a short walk or a relaxing swim on a semi-regular basis—this can help you fight fatigue and get a better night's sleep (4).

#18. You'll learn proper breathing techniques that can help during your delivery

Exercises such as yoga can help you learn the breathing rhythms that are essential in keeping you calm and focused while giving birth (6).

#19. You'll feel better about going into childbirth

First-time mothers may question their ability to give birth, but when you exercise, you are setting yourself up for success.

Childbirth will be easier for you when your body is prepared. This knowledge will give you confidence and relieve some stress you may be feeling.

#20. Exercising during pregnancy can take your mind off of things

Being pregnant can definitely be stressful, but taking the time to exercise will give you the much needed relief to clear your head of all the what ifs.

Exercising Benefits for Both You and Baby

#21. Regular exercise can increase your baby’s brain function

Studies have indicated that babies of mice who exercised daily were less prone to neurodegeneration, which are changes in the brain that can lead to Alzheimer’s disease (11).

#22. Expectant mothers who exercise tend to keep up the habit after their babies are born

If you're still exercising after you've given birth, you'll have a lot more energy to be active with your little one once they arrive.

#23. Studies show that mothers who exercise produce children that are leaner than mothers who don’t

And even though the baby is thinner, its organ size and head circumference remain the same healthy standard doctors look for when delivering children (17).

#24. Baby will be less likely to incur complications such as cerebral palsy

Exercising during pregnancy increases the blood flow to your child. And without a good flow, your baby could be at risk for oxygen deprivation from birth (21).

#25. Babies of mothers who exercise regularly are more likely to have a healthier heart

A 2014 study showed that infants born to mothers who participated in regular exercise were more likely to have a healthy fetal heart rate variability (13) (15).

#26. You're less inclined to have an overweight child

Babies who are born with excess fat are more likely to be overweight throughout their early childhood (19), and babies born 20% or more over the recommended weight are at risk of becoming obese adults.

#27. You're more likely to carry your baby to full term

Exercising during your pregnancy can help prevent a premature birth, which can lead to many complications for baby, such as immature lungs, infections, inability to maintain body heat, and pneumonia (22).

#28. Babies born to mothers who exercise semi-regularly are less at risk for learning disabilities

Placental insufficiency can lead to a variety of learning issues, if not caught early on in your pregnancy (21).

Post-Delivery Benefits of Exercising During Pregnancy

#29. Exercise can help promote better sleeping habits

Did you know that exercising during your pregnancy can help you sleep better once baby comes along? (23). And as a new mother, you are going to need all the quality sleep you can get!

#30. Women who exercise during and after pregnancy are less likely to have postpartum depression

The endorphins released from exercise can help you feel relaxed (9). Moderate exercise has been prescribed for patients with mild to moderate depression (10).

Exercising as a social event can create a fun atmosphere that will boost your mood even further. Try exercising with a friend or a group.

#31. Exercise can make it easier to drop weight once you have your baby

Studies have shown that women who gain more than the recommended 25-35 pounds throughout their pregnancy will have a harder time losing that weight (14).

#32. Incorporating physical activity into your daily routine will ultimately give your child a positive example for years to come

Exercise at an early age can boost your child’s brain function (24).

#33. Abdominal workouts can help lead to a faster recovery

After the first trimester, stick to exercises that don’t require you to be on your back.

Some great abdominal exercises include standing pelvic tilts, seated belly tightening, along with any other core exercises you can complete seated (2).

#34. Regular exercise while pregnant will help you bounce back quicker from pregnancy

Completing the American College of Obstetricians guide of 20-30 minutes of exercise daily can assist in preparing you for bouncing back from your postpartum period (20).

#35. You'll be more likely to continue your exercise once you child is born

Starting healthy habits can keep you lean and strong through your lifetime giving you more memories with your child.

Three Unusual Questions about Archery

I have heard some of these questions before, and one of them (the last one) I have only encountered today. I thought the last question was rather odd, so I thought I would talk about the three questions in hopes of Busting some Myths.

Question #1: Do I need a license to do archery?

No.

You do not need a license to practice archery.

 You need a hunting license (H1 or H2) to go bowhunting, but you do not need any sort of license to practice archery for recreation or competitions. And even if you do have a hunting license, you can only hunt during specific hunting seasons, only for game allowed during that season, and only if you have any required tags for that specific animal. eg. deer tags for deer hunting season. You have to abide by all of the laws and regulations with respect to bowhunting, and not following those laws can result in the forfeiture of your hunting license, a large fine and even prison time.

For example: In 2014 a Peterborough man, Dave Sager, was fined $1,000 and had his hunting license suspended for a year for accidentally shooting his son with a crossbow bolt. He was trying to unload his crossbow incorrectly. He was allowed to get his hunting license back after a year and after retaking the hunter education training course.

There is also bowfishing, for which you need a fishing license, can only bowfish during carp bowfishing season, and must follow all laws and regulations regarding where and when you are allowed to fish.

Question #2: Do I need a hunting license to purchase a bow or crossbow?

No.

Like the above question, this is a frequently asked question. The answer is no. You only need a hunting license if you are intending to go hunting. Anyone can legally buy a bow or a crossbow and they don't need a hunting license or any other kind of license to do so. There is however a requirement that you don't have any kind of weapons ban (due to past criminal activity).

eg. I know of an individual in the GTA who was involved in an aggravated assault (he beat up someone who was abusing a kid) and as a result he spent some time in prison and ended up with a lifetime weapons ban. This resulted in him having to sell any weapons he owned, including his Excalibur crossbow. He is the only person I know of personally who is banned from owning any kind of archery equipment.

Also we should note that certain weapons are just plain prohibited in Canada. Hand Crossbows for example are illegal in Canada.

As long as you are not an ex-con and you are not trying to purchase a prohibited weapon, then you will be just fine.

Question #3: Do I need a certificate proving that I know how to do archery to join an archery club?

No.

Or at least none of the archery clubs that I know of, and I am the president of both the Toronto Archery Club and Archery Niagara. To my knowledge none of the other clubs require any sort of certificate either.

I found this last one rather odd. Someone had apparently told the individual that they needed a certificate in order to join various archery clubs in Toronto. Sadly they were given false information. As president of the Toronto Archery Club I have made a mental note to someday have a chat with the person giving out false information and let them know that, no, the Toronto Archery Club does not require any sort of certificate whatsoever.

I have never seen the need to offer any kind of certificate to archery students, with one exception: I do offer an Archery Instructor Certificate Program, designed for people who want to teach recreational archery (usually at summer camps, resorts, etc).

If you have additional archery related questions or if you wish to sign up for archery lessons in Toronto simply email cardiotrek@gmail.com to learn more.

Happy Shooting!

Bras Vs Bust Firming Exercises

According to a study that came out of France in 2013, bras don't actually alleviate back pain in women and don't do anything to prevent women's breasts from sagging. In fact, the study says that it actually makes back pain worse and the breasts to sag more.

Of course, anyone familiar with Bust Firming Exercises already know this. Marilyn Monroe knew this and she has been dead for almost 54 years.

While she was living however Marilyn Monroe did a number of daily exercises in order to stay in shape and keep her famous figure.

They included:

Push-ups - which act as bust firming exercise, increasing the strength of the pectoral muscles on the chest, which hold up the breasts and keep them from sagging.

Weightlifting, including Chest Flyes (below) which also work the pectoral muscles.

Jogging, for the legs and arms.

Archery, for the back muscles and arms.

Swimming, good as a full body workout.

Stretches (some of which look suspiciously like yoga).

And while she may have occasionally worn something that looked similar to a bra (due to society's convention against women appearing topless in public), she almost never is shown wearing a bra. Many of her iconic pieces of fashion went in quite the opposite direction. No bra at all.

And she certainly did not need to wear one either. Due to her regular exercises and specifically bust firming exercises, she had no need of wearing a bra which at the time conventional thinking was that women needed to wear bras in order to prevent back pain.

According to the 2013 French study, everything we've ever been told about supporting the upper back has it all wrong. Wearing a bra does nothing to decrease back pain, and the support offered by a brassiere actually encourages the breasts to sag. The study was a lengthy one too, starting in 1997 and ending in 2012, before being published in 2013. 15 years of women in the study group either wearing a bra or wearing no bra, and comparing which ones had back pain and which ones did not, and measuring how much sagging was really happening.

Led by Jean-Denis Rouillon, a sports scientist from the University of Besançon in eastern France, he found that "bras are a false necessity."

"Medically, physiologically, anatomically — breasts gain no benefit from being denied gravity. On the contrary, they get saggier with a bra," says Rouillon.

Rouillon spent a decade and a half measuring the changes in breasts of hundreds of women using a slide rule and caliper at the Centre Hospitalier Universitaire in Besançon. The participants were all between the ages of 18 and 35.

Of the braless women, the researchers concluded that "on average their nipples lifted on average seven millimeters in one year in relation to the shoulders." This meant that they effectively became "perkier" over time as their pectoral muscles became stronger from the added weight, as opposed to the extra strain going to the shoulders and back muscles instead.

According to one 28-year-old woman who took part in the study she hasn't worn a bra for two years now, and doesn’t expect to go back. "There are multiple benefits: I breathe more easily, I carry myself better, and I have less back pain," she says.

So less back pain, less shoulder pain, stronger pectoral muscles, better posture, stronger lungs. Lots of benefits. Learn more about Bust Firming Exercises.

Note, men who want larger pecs / chest muscles can also benefit from these exercises. eg. Arnold Schwarzenegger is a huge advocate of Chest Flyes, shown below, for its benefits of building huge pectorals on men.

The Myth of Spot Training for Skinny Arms

Earlier today I saw a website promoting the myth that doing weight lifting exercises for your arms can help women to get "skinny arms". The website contained a list of exercises, mostly weight lifting exercises like bicep curls and body weight exercises like push ups. It made me so angry I wrote a lengthy comment on their website.

My comment below:

"Wow. Such misinformation. The exercises listed above would give people BIGGER arms, not skinny arms. I am a personal trainer and I come across misinformation like this way too often.

#1. Doing weight lifting or body weight exercises will make your arms get BIGGER, not smaller, because you will be building more muscle.

#2. Spot Training for Weight Loss is a MYTH. You cannot do weight training with your triceps and expect your triceps to shed fat. It doesn't work that way.

#3. If you want to shed fat you need to be doing cardio. Jogging, swimming, cycling, aerobics, etc.

#4. Extra skin is normal after sudden weight loss, but there are tricks to fixing that problem - they're listed on my website."

The level of misinformation in the exercise industry boggles my mind quite often. It is due to a combination of factors:

#1. People who just plain don't know what they are talking about. They are perpetuating a myth due to sheer ignorance.

#2. Companies that are trying to sell you a product and are deliberately giving you false information in an effort to trick you into buying their product.

#3. Personal Trainers who have become so focused on one style of training that they warp, twist the truth and outright lie to their clients. Eg. Weight lifting trainers telling people that they can lose weights using weightlifting - or vice versa, cardio trainers telling people they can build lots of muscle by going jogging.

The third cause above makes me so angry because it means my own industry is partly to blame for the misinformation. It not that my fellow colleagues are stupid or anything, they are simply doing math: more clients = more money, and men who can easily be tricked into thinking weightlifting sheds fat is an easy way to get more clients. It is basically preying on the gullible and/or the ignorant.

But for a website that isn't actually selling anything, that is just posting free information (or free misinformation) what is the purpose of that? They don't make any extra money off perpetuating a myth. Unless they were selling a product I wasn't aware of, or maybe it was the advertising on the website - which implies that their primary goal is to keep their advertisers happy, not to inform the public.

And so to summarize:

Weightlifting and resistance training builds lots of muscle. It will not give you skinny arms. Spot Training to build muscle does actually work, but it only works for building muscle - not for shedding fat.

Cardio exercises shed fat. So if you are looking to shed the extra arm fat, you need to be thinking of a full body workout like jogging or swimming.

Spot Training to remove fat in specific areas is a myth. You can build muscle in specific spots, but you cannot shed fat in that manner.

If your goal is to do BOTH, to build muscle and shed fat at the same time you need to be doing a combination of both cardio and weightlifting. Eg. 15 minutes of weightlifting and a 15 minute jog every day.

FACT - 30 minutes of exercise per day is approx. 2% of your day, but that 30 minutes of exercise can make a big difference towards your exercise goals.

The #1 Reason Why So Many People Fail To Lose Weight

Do you want to know the #1 reason why many people who set out to lose weight via exercise fail to lose the weight they are looking for?

The answer is...

NOT ENOUGH CARDIO

Many people who go to the gym (or set up a home gym) do so by lifting weights or doing various forms resistance training, which in turn builds muscle.

What often happens is the person ends up GAINING WEIGHT due to increased muscle mass. They aren't reducing their overall weight and while their body fat percentage may go down slightly, they are not going to get the results they are looking for.

It is basically an issue of people equating cardio exercises like running, jogging, swimming, cycling, etc with weightlifting exercises and thinking that they can get the benefits of weight loss from weight lifting - and instead they gain weight by building muscle, while seeing no change at all in their waistline. They have fallen victim to the myth that "you can lose weight by weightlifting".

There are of course, exceptions. I will give you a few:

#1. Put weights around your ankles and go for long walks. That is basically combining weight lifting for your legs with cardio - but it is still effectively cardio.

#2. Put a 20 lb backpack on and then go cycling. Yes, you are lifting extra weight on your back, but the more important factor is that cycling = cardio.

#3. Combine aerobic exercises with small 5 lb dumbbells. Yes, you are lifting weights, but again the bigger factor is that aerobic exercises = cardio.

So yes, of course, if you combine weightlifting with cardio you could lose weight - but the bigger weight loss factor is always going to be the cardio.

Your primary goal during a cardio exercise is to get your heart rate going - and trigger the Afterburn Effect (heightened metabolism as your body burns fat for energy). If you don't get your heart rate high enough to trigger the Afterburn Effect, then you are going to have difficulty trying to lose weight. Often people exercising with just weightlifting are just going to use up the energy in their blood (sugar, fat, etc) and then feel hungry and tired.

In contrast if you trigger the Afterburn Effect you suddenly feel energized - more energetic and alive, for the rest of the day as your body starts burning fat to refuel your body's energy levels. Scientific studies show that the Afterburn Effect can last up to 48 hours after the person achieves a high heart rate from doing cardio - and the more prolonged their heart rate is higher, the more their body starts burning fat.

Triggering the Afterburn Effect is part of High Intensity Interval Training and other forms of Interval Training. So if your goal is to lose weight, you might want to consider Interval Training as a method of getting your heart rate up in your goal of losing weight.

The goal during High Intensity Interval Training is to get your heart rate up doing one intense exercise, and then relax while doing a less stressful exercise, and then get your heart rate back up again by doing another intense exercise.

Example 1. Sprinting, Walking, Sprinting, Walking, Sprinting, Walking, etc.

Example 2. Aggressive Mountain Biking, Relaxing Cruise, Aggressive Mountain Biking, Relaxing Cruise, Aggressive Mountain Biking, Relaxing Cruise, etc.

Example 3. Fast Swimming, Leisurely Swimming, Fast Swimming, Leisurely Swimming, Fast Swimming, Leisurely Swimming, etc.

Scientific studies have also shown that 30 minutes of  High Intensity Interval Training is more effective for weight loss than 30 minutes of jogging - because your heart rate gets higher while sprinting, and a higher heart rate triggers the Afterburn Effect better.

So not only are people often doing the wrong exercises for their goal, people are often opting for exercises they consider to be easier - because they know sprinting and similar intense exercises are pretty hard.

But not impossible.

Sprinting is basically just running as fast as possible for a short period of time. Anyone with working legs can do it, so chances are likely you have no excuses.

Anyone with bad knees would be advised to do swimming instead.

But once you start doing more intense cardio on a regular basis you will feel invigorated every time you do - that is how you will know the Afterburn Effect is working. The feeling of invigoration.

Exercise + Nutrition Vs Advertising

I am going to go a bit off topic today, but my goal here is to talk about the advertising industry and its place when it comes to both the exercise industry and the food industry. Time for some myth busting!

SAY CHEESE

You would think, judging by TV commercials for cheese that cheese is inherently good for you because it contains lots of calcium. This is only partially true.

It only takes a Google search to find hundreds of articles about the Cheese Lobby in both the USA and Canada, and how it is being used to sell everything from fattening cheese pizza to cheesy Taco Bell to cheeseburgers and more...

eg. Read the NY Times article: While Warning About Fat, U.S. Pushes Cheese Sales

Fun Fact: "Americans now eat an average of 33 pounds of cheese a year, nearly triple the 1970 rate."

The Cheese Lobby in the USA is HUGE. They represent every fast food chain that has cheese on the menu, whether it be cheese pizza or cheeseburgers. Their goal? To fool North Americans into thinking cheese is healthy for you because it contains calcium.

Truth be told when you actually check milk and cheese isn't actually a good source of calcium. Milk is actually a good source of protein, and cheese is a good source of fat. Cheese is something you should be asking for less of, not more of.

Want a good source for calcium? Check out the vegetables below.

FIVE RED FLAGS

To demonstrate how bad the food industry is sometimes I am going to show 5 Red Flags to look for when you are watching advertising:

#1. Exotic Ingredients from Asia, Brazil, Africa, Etc.

The idea here is simply: To fool people into thinking that you can lose weight by eating some kind of exotic berry (acai berries for example) or fruit from a place you've never been to (South African Hoodia Extract). If they're pushing something exotic for a hefty price, they're basically just selling you juice or extract for something you don't actually need.

#2. Fake Studies with Fake Doctors

If they have to back up their product with a study from a doctor, most likely the doctor in question is either not a real doctor or he/she is being paid oodles of money to push a bogus study that says their product works. Often there will be a photo of a doctor dressed in white holding a supplement.

#3. Free Trial

Free Trials are a great way to get gullible people hooked on a product that doesn't really work any better than a placebo. Plus when you try to cancel they make it very difficult to do so - you basically have to cancel your credit card to get rid of them. Note - Many companies stick an addictive agent (caffeine usually) in the product so you become addicted to the product.

#4. Celebrity Testimonials

It doesn't matter whether the celebrity is a bodybuilder or Oprah, if they are pushing the product using a celebrity then then company's primary goal is to make money off gullible people.

#5.  Too Good to be True

If it contains the words "Lose Weight Fast and Easy" or some similar slogan, you know they're lying to you.

THE FITNESS LOBBY

If you Google the words fitness lobby you will get a bunch of gym websites and photos of lobbies of gyms. The reason why, apparently, is because there is no "Fitness Lobby" in the USA or Canada (or in any other country for that matter).

I did manage to find one article about fitness groups lobbying for a tax break, but it wasn't an actual lobby group being paid to lobby the government, it was simply a selection of fitness groups trying to get a tax break. They only had one cause and they weren't being paid to do it, whereas lobby groups are basically hired thugs being paid to fight on behalf of the tobacco industry, the cheese industry, the oil industry, and basically any industry which everyone knows is doing something bad.

How many decades did the tobacco industry use lobbying to keep cigarettes being sold and how many more decades will they continue to do so before smoking cigarettes gets banned in North America for causing ridiculous amounts of cancer and killing two thirds of smokers? An industry that kills 66% of its customers is doomed to eventually get banned.

In contrast the fitness industry doesn't kill people when they are selling new fitness gadgets.

But it does use false advertising, like the Fake Doctors, Free Trials, Celebrity Endorsements, and Too Good To Be True slogans mentioned above.

But here are additional tricks used in advertisements:

#1. The fitness industry often uses people who were already thin and attractive (or already lost weight) before they started using whatever new fitness gadget is being pushed at the consumer. So regardless of whether they are trying to sell a Thigh Master or a Bowflex, their goal is to show you people who are already fit using the product. They don't show you people who overweight and not fit using it and then the slow progression of them losing weight - that would be too time consuming, and also impossible because people would realize that the people using the product are also using other kinds of exercises.

#2. They don't mention that people using the product should also be using a wide variety of other exercises - such as jogging, swimming or cycling - in their goal to lose weight.

#3. They ignore the fact that a home gym composed of weight machines really only builds muscle and is useless to someone who wants to lose weight by shedding fat. To shed fat they need to be doing cardio exercises.

#4. Fitness gyms sign people up for 1 year contracts and then make it difficult to cancel the contract by charging the membership fee every month even after the contract has been finished or cancelled. Fitness gyms claim it is due to clerical errors that people are routinely charged again and again even after their contract has expired or been cancelled.

#5. Fitness gyms routinely overcharge members for their membership fee, for an inflated amount with hidden fees - or sometimes charge the membership fee twice in the same month. Or both.

#6. Fitness gyms offer personal training services, but often charge ridiculous rates for those services while paying their staff peanuts. eg. Extreme Fitness charges $80 to $90 per hour for the services of a personal trainer, but only pays the trainer $17 to $20 per hour.

So the fitness industry doesn't really need a fitness lobby because they're already making lots of money off gullible people signing up for fitness gadgets they don't need and gym memberships they likewise don't need.
