We decided to take advantage of our fitness expertise to compile 5 fitness facts that, you guessed it, everyone gets wrong. There are many common fitness facts, frauds and myths that are not on this list and some weird ones that are.
This list is comprised of 10 that we've found are often misunderstood and that I want to clarify.
You need to train hard to see your abs
Remember Iggy Pop and his rippling abs? Do you think after a show he was going to the gym to do abdominal crunches on a Swiss ball? No, he was heading back to his hotel room to shoot smack and bang groupies.
And what he wasn’t doing was eating that much, because heroin suppresses appetite. Being in a state of regular caloric deficit kept Iggy’s frame at a low body fat level, and the abs popped out. That’s the way it works. You can enhance the look of your abs with some focused work, but if they’re covered in flab, no one will ever know.
Exercise is about burning calories
Burning calories is just about the least important thing exercise does. Far more important is what is known as a “training effect.” Exercise has the ability to make you stronger, faster, more agile, and more flexible. It can make you more skilled at various sports and enhance your cognitive capabilities. It also enhances immune function and promotes longevity.
Weightlifting is an effective fat-loss strategy
Weightlifting does burn calories, but when compared to hard aerobic training, it pales. A hard session with the iron burns only 20% more calories per hour than walking at 4 mph, according to Essentials of Strength Training and Condition. And I’m sorry to tell you that adding muscle does not rev up your resting metabolism.
Low-carb diets are effective for weight loss
The only thing that matters is calories. Caloric deficits can be done in a healthy way and an unhealthy one. Many experts consider low carb to be unhealthy, and I agree with them. I know that some experience weight-loss success with this approach, but I consider this diet as a last resort for the lazy.
Yes, there is evidence that it can be good for controlling appetite because of the high protein levels and the fact that the diet restricts a bunch of bad carbs that are high in calories. However, it also restricts the good carbs that are essential for exercise performance, the ones that can be quite satiating and contain valuable nutrients.
A high-protein diet is effective for gaining muscle
At a certain point, you just don’t need it anymore. Unless you’re shooting the juice and training long hours to build muscle fast, your body can only use so much. I had some conversations with nutrition expert Alan Aragon who told me that those looking to gain weight only need about 1.4 grams of protein per kilogram of body weight per day.
