Sore muscles? Work 'em some more

Your last workout left you with sore muscles. What do you do: Sit still? Or keep moving?

When it comes to exercise, a little bit of what ails you will make you better, says Andrew Pruitt, director of the Boulder Center for Sports Medicine in Colorado. Yep, the quickest way to heal sore muscles is to work them some more. It increases blood flow and delivers nutrients where you need them, Pruitt tells The Oprah Magazine (November 2008).

Don't be discouraged by soreness. It simply means your body is adapting to your fitness routine. And don't worry that you need to go all out as you repair your body. Gentle movement works wonders. Try walking -- you'll heal faster and burn calories at the same time.
