I have been practicing ashtanga yoga 4-6 times a week for several years now. I must say that it suits well to a programmer. Even though I sit by the desk about 8 hours a day, I never have any aches or pains. The daily practice kind of moves the body to the background, since the body becomes quiet and it does not complain. Practicing yoga postures also involves meditation, so its a good way to relax.

I suppose this can be achieved by practicing martial arts as well. The main thing is to have a regular exercise that you find meaningful.
