It depends on what your physician says.  My physician wanted me walking at 30 minutes a day at first.  After I got my staples out (2 weeks postop) I started doing walk away the pounds DVDs for 15 minutes and walking.  I had to start out slowly with my aerobics finally working my way back to 45 minutes of aerobics then to an hour.
