After about six to eight weeks, assuming that the surgical wound has healed well, you can begin nearly any form of exercise. The general principle is to start slowly. If you used to jog five miles, start by jogging 1/2 mile first, then work your way up to your goal. If you used to lift 100 pounds at the gym, start with 20 pounds. Multiple repetitions of any exercise at a lower weight are better than trying to lift too much too soon.
