Check out the top ten exercise myths below to see if any of your long held beliefs might be due some second guessing. Exploding exercise myths might step on some toes sometimes but let's face it - there are fitness myths, diet myths, weight loss myths, and general health myths everywhere we turn. Pick up almost any fitness magazine and you are bound to see one of these exercise science myths:
The Top 10 Most Common Exercise Myths Debunked
What is exercise fact vs myth? The craze surrounding exercise, weight, health, and fitness in America is a curious thing. Huge government subsidies make grains (like sugary cereals and nutritionally-empty white bread) artificially inexpensive. Fast food like McDonalds and Wendy's is some of the cheapest commercially available food in the world.
Advertising for bad food, beer, and liquor is everywhere. However, who is always hocking this terrible food and booze? Some of the fittest, most attractive people around. People used in advertisements, if not outright fit and athletic, are at least trim and not overweight or obese.
Given the overweight and obesity epidemic in this country, there's a huge disconnect between the general public and the people given the most space in advertisements. We are simultaneously told that being fit and athletic is what we should strive for, even as these people push products at us that do just the opposite.
Well, for better or worse, the outcome of this two-faced advertising is the rise of gyms, group fitness classes, and an increase in the number of people who exercise regularly. Now, that's the good thing. There are a myriad of benefits to exercise, besides looking better: lower blood pressure, better metabolism, etc. Check out all of our free workout plans to see just how many benefits you might be able to experience by making fitness a habit!
However, the rise of all this exercising (like when any past-time or product becomes more popular with the general public) has led to a glut of exercise misconceptions, myths, and outright lies. Most of these are a result of people genuinely trying to do what's best for their bodies and not getting good information. Others are misunderstandings of your body's sometimes confusing biochemistry. Some are outright lies. Let's sift through some of the most popular myths about exercise and shed the light of truth on them.
Modern technology is awesome. It allows us humans to do things we've never been able to do before in all of our years of development. It has also come with its share of drawbacks and weaknesses. One weakness is our current over-reliance on technology for information and our tendency to trust whatever a machine tells us blindly.
Case in point, you jump on the treadmill, stair master, elliptical, or exercise bike, and the little LCD screen starts displaying information: speed, challenge level, etc. It also purports to tell you how many calories you are burning as you exercise. Wrong. There are a million different factors that play into how quickly you burn calories while exercising, including your age, fitness level, muscle mass, sex, and much more. Many machines don't measure all these different factors. So how could their results be even remotely correct? Short answer: they're not.
This next myth is somewhat related to the first one. Heart rate monitors are all the rage these days. Improvements in technology make them cheaper, smaller, easy to afford and a breeze to use. They are built into many stationary cardio machines. The logic seems to be that they give you an accurate depiction of how hard you are working while exercising. In fact they are unreliable depending on which kind of exercise you are doing.
A better (not to mention cheaper) way to figure out how hard you are working is by trying to talk. Full sentences means that you're not working at full capacity. Short phrases indicate a higher level of intensity, while barely being able to get out a few words at a time means that you are probably at or around max workload and should think about backing off for a moment or two (before ramping back up, or ratcheting down, depending on your workout plan).
Most people hopefully have left this myth behind, but it's a number, and people love numbers. It's easy to get stuck on numbers. They go up, they go down, they show clearly visible, measurable results. However, your weight is far from the most important part of measuring your fitness journey.
For starters, it has little to do with how "fit" you are. Body fat percentage and other metrics, based on performance (sprint speed, mile run, lung capacity, etc.), are much more accurate when it comes to establishing your level of fitness. Also, muscle weighs more than fat. If serious weightlifting is a part of your training program, then you could be developing pounds of heavy muscle as you shed fat.
A better way of determining if your program is working for you is if your clothes are fitting better and how you feel overall. For added information-gathering, consider adding tape measurements to your progress tracking. Waist, hips, leg, and arm, measurements all provide valuable data about how your program is going.
Another myth (possibly propagated by the lazy) is that lower intensity exercise burns more fat (as opposed to high intensity exercise that burns...I don't know what...). In reality, intense exercise (usually done in short bursts, with brief rest periods, in a method called "High Intensity Interval Training" or "HIIT") quickly burns up any and all carbs in your blood stream, then sends out chemical signals to release fat from your fat stores.
Chugging a protein shake after exercising is not a good idea. You are not giving your body its needs to replace nutrients, repair microscopic tears in your muscles, and replenish fluids. All protein shakes are not alike. Many are low-quality processed products with questionable ingredients. It is difficult to pronounce the words or know what they are.
The most important meal is the one after you exercise. For about an hour after your workout, your muscles are famished and needs nutrients. Whey protein powder, eggs, meat, fish or chicken, will replenish your body’s supply of amino acids which your body uses for making neurotransmitters, bones, hormones and muscles. Exercise depletes crucial amino acids; These are best replenished with protein in food, not from questionable protein shakes.
Due to muscle memory, in response to hard workouts, the proprioceptor cells in our bodies prevent damage to our muscles and joints by either contracting them, or doing the opposite, signaling a relaxation response. These protrioceptor cells signal the body to stop exercising or engaging in other stressful activity before it passes the safe apex and hurts itself.
When pushed too far, the body and muscles remember the event and the injury. Even after the injury has healed, the muscles will contract whenever they near the position in which the injury took place. Triggered by the response, the muscles try to avoid another injury of the same type.
Repetitious exercises that target only specific muscles may not only harm them, but creates an ineffective workout. It is like exercising by remote. There is a purpose for muscle memory, but humorously, spot reducing may give the muscles Alzheimers.
You cannot pig out on any fat burning workout and lose weight. On the other hand a deprivation diet does not work either. Exercising, or running on an improper diet without all the nutrients your body requires is running your body — down. The body senses a depletion in calories and strives to prevent a collapse, or exhaustion, so it is more difficult to lose body fat.
Muscles need food — nutrients — to aid in the repair of wear and tear on them, to replenish vital fluids and to replace utilized nutrients. A good diet consists of a balance of fluids, fats, proteins and carbohydrates. Check out some bodybuilding diets to see what it takes to properly provide your muscles with the correct amount of nutrients.
It is a proven fact that more calories are burned in 30 minutes of weight training than in a 30-minute run at the same intensity. However, increased cardio makes your heart, lungs and endurance stronger, but does not trigger the body’s weight loss mechanisms.
The muscles that have greater energy stores will actually begin to feed off themselves after extended cardio exercises. Thus, the body does not burn its fat stores. In 10 to 25 minutes of cardio, your heart, lungs and endurance obtain all they need. Why not add running to your cardio regime and lose body fat, by allowing the muscles in the body, especially in the limbs to burn body fat off the whole body?
After not eating for eight hours or more, the body’s metabolism is at its lowest. Feeling weak, and perhaps even nauseous during a workout may quickly discourage you from exercise the next morning.
So, eat a good, balanced breakfast with a healthy serving of protein and exercise with great potential! Your metabolism will already be stoked up and ready for a good workout geared toward a stronger heart, lungs and endurance.
There are no proven facts, or studies which indicate that you can shock your body into losing weight by forcing it to keep warm. Your metabolism will not increase and burn fat.
On the other hand, you can throw your body into hypothermia by eating snow when lost out in the cold. Your body will use its energy to heat the snow. This is not a weight loss regime; It is a survival decision of epic proportions!
Your body will burn only 70 calories by your drinking 64 ounces (eight glasses) of water per day. This is not anywhere near as effective as exercising or walking to lose weight. Only muscular exercise will increase your metabolism. However, if your body compensates for dehydration by retaining water you may believe you have actually gained weight.
Drinking too much water, warm or cold, causes too little sodium in the blood (hyponatremia) and is also a serous threat to the kidneys. Our bodies were not built to handle great quantities of water and by overwhelming the kidneys, we can die of water “intoxication.”
