Ab Exercises???

How far out after surgery did you start really doing ab exercises? This is something that I really need to work on but I have a little reservation after having internal stitches. I have been released to do full exercise but I do still have a little uncomfortable (not pain) feeling in my belly button incision when I bend down. The only other incision I had is about 1/4" on my right side. I haven't felt any issues with that one. I just really want to start trying to tighten things up.

I didn't really do anything but cardio (and skiing) for about 6 weeks.  Then anything was fine.

I was told six to eight weeks before I could do anything more strenuous than light cardio. Be patient, there's no need to rush. You will have a lifetime to do crunches so there's no sense risking your recovery by waiting.

most surgeons say after 6 weeks you can do anything your comfortable doing but I would wait 2 months to be safe

Six weeks!  But remember that no exercise in the world will keep your skin tight.  Sad :/

Just don't go too gung ho and give yourself a hernia.
