Myths of exercise.

There are quite a few.

Perhaps the most pernicious is that you're overweight because you don't exercise enough.

Exercise makes you hungry, so you're likely to eat more if you exercise more.

Plus it's trivially easy to eat more calories than you burn, if you eat the modern diet.

Exercise doesn't burn as many calories as people think either.

You've got to run 5 miles to burn 500 calories.

Proper exercise should involve training, not just moving around.

It should build muscle.

If you don't train to build muscle, you're losing it.

If you exercise properly, you don't need to do it all that often.

Your body doesn't lose exercise benefits in a few days, or even longer.

(Doesn't mean you should be sedentary, of course.)

Recovery is important.

If you don't rest and recover, improvement will falter.

Muscles grow outside the gym, not in it.

If you do steady-state aerobics, the only way to increase your fitness is by increasing the duration.

That's how people end up running for hours.

If you exercise at high intensity, you're always pushing against your limits, and therefore always improving.

Exercising at lower intensity than you're capable of will not improve your fitness.
