9 Excersise Myths

WebMd Busts 9 Excersise Myths Here are some that I heard lately

Fitness Myth No. 2: Doing crunches or working on an "ab machine" will get rid of belly fat.

Don't believe everything you hear on those late-night infomercials! Harr says that while an ab-crunching device might "help strengthen the muscles around your midsection and improve your posture," being able to "see" your abdominal muscles has to do with your overall percentage of body fat. If you don't lose the belly fat, he says, you won't see the ab muscles.

But can doing ab crunches help you to lose that belly fat? Experts say no.

"You can’t pick and choose areas where you’d like to burn fat," says Phil Tyne, director of the fitness center at the Baylor Tom Landry Health & Wellness Center in Dallas. So crunches aren't going to target weight loss in that area.

"In order to burn fat, you should create a workout that includes both cardiovascular and strength-training elements. This will decrease your overall body fat content," including the area around your midsection, he says.

Fitness Myth No. 6: If you're not working up a sweat, you're not working hard enough.

"Sweating is not necessarily an indicator of exertion," says Tyne. "Sweating is your body’s way of cooling itself."

It's possible to burn a significant number of calories without breaking a sweat: Try taking a walk or doing some light weight training.

Fitness Myth No. 7: As long as you feel OK when you're working out, you're probably not overdoing it.

One of the biggest mistakes people tend to make when starting or returning to an exercise program is doing too much too soon. The reason we do that, says Schlifstein, is because we feel OK while we are working out.

"You don't really feel the overdoing it part until a day or two later," he says.

No matter how good you feel when you return to an activity after an absence, Schlifstein says you should never try to duplicate how much or how hard you worked in the past. Even if you don't feel it at the moment, you'll feel it in time, he says -- and it could take you back out of the game again.

Fitness Myth No. 9: When it comes to working out, you've got to feel some pain if you're going to gain any benefits.

Of all the fitness rumors ever to have surfaced, experts agree that the "no pain-no gain" holds the most potential for harm.

While you should expect to have some degree of soreness a day or two after working out, Schlifstein says, that's very different from feeling pain while you are working out.

"A fitness activity should not hurt while you are doing it, and if it does, then either you are doing it wrong, or you already have an injury," he says.

As for "working through the pain," experts don't advise it. They say that if it hurts, stop, rest, and see if the pain goes away. If it doesn't go away, or if it begins again or increases after you start to work out, Schlifstein says, see a doctor.
