While I would agree to the 'less is more' adage right after surgery, for individuals who had previously been accustomed to more strenuous workouts, I would say go ahead and re introduce it. I have been a marathon runner for many years and was able to take up running again about two months post op. I am slower than I had been but I don't find any negative effect on the pouch. Each to his/her own though. I am not as certain about weight resistant type workouts though.
