Top 9 Fitness Myths -- Busted!

It's easy to fall into the trap: A workout buddy passes along an exercise tip, and then you pass it on to several folks you know. One day, you're at the gym, and sure enough, you hear the same tip repeated, so you figure it must be true. But experts say that in the world of fitness, myths and half-truths abound – and some of them may be keeping you from getting the workout you need.

"Some myths are just harmless half-truths, but many others can actually be harmful," says professional triathlete and personal coach Eric Harr, author of The Portable Personal Trainer. "They can cause frustration in working out and sometimes even lead to injury," he notes.

One reason myths get started, says Harr, is that we all react to exercise a little differently. So what's true for one person may not be true for another.

"In this sense you sometimes have to find your own 'exercise truths' – the things that are true for you," says Harr.

That said, experts say there are also some fitness myths that just need busting, and the sooner the better!

Exercise 'must be tough to work'

To be healthy, you really do need to break into a sweat when you exercise, say experts.

Recently, researchers at Queen's University, Belfast, found walking for half an hour on just three days a week gave similar fitness and blood pressure benefits to walking for 30 minutes five times a week.

The sports scientists, however, say this advice is misleading and could encourage people to do too little exercise.

"There are people who have not accepted, and others who have misinterpreted, the original recommendation.

"Some people continue to believe that only vigorous intensity activity will improve health while others believe that the light activities of their daily lives are sufficient to promote health," they told Circulation.

This article contradicts one of the myths on that list.
