10 Stubborn Exercise Myths that Won’t Die, Debunked by Science

[MindMover]

"No pain, no gain!" "You'll never bulk up without supplements." "Crunches are the key to six-pack abs!" It seems there are more questions and half-truths in the market about healthy exercise than there are clear, definitive facts—but the exercise industry is a multi-billion dollar business in the United States alone, built partially on selling gadgets and DVDs with incredible claims to people desperate to lose weight or look attractive. Meanwhile, good workout plans and simple truths lurk in the background waiting for their time to shine. All of this results in a ton of misinformation about exercise in general, and while the reality is different for everyone, we're taking some of those commonly held exercise myths to task, and we have science to back us up. Let's get started.
We've tackled food myths, more food myths, brain myths, and even body myths. This time it's time to take a look at exercise myths, and we enlisted the help of Dr. Brian Parr, Associate Professor in the Department of Exercise and Sports Science at the University of South Carolina Aiken, to help us out. Here's what we learned.

2. These are worth reading! Considering all the (free) benefits of

exercise, it's remarkable people spend billions on diets, medicine, medical proceedures and expensive machines when plain old exercise is the real 'wonder drug'.

thanks, MM!
