Workin' the abs/incision question

Hi guys! I'm new on this board, but I had a couple of questions for some of you. I'm still pre-op, but have a membership to an awesome gym and am quite looking forward to going back after surgery. I'm having laparoscopic RNY, and wanted to know if I'll be allowed to do abdominal toning. I know you're at more risk for a hernia if you have an open incision. I'm considering slowly but surely starting a weightlifting routine to curb the excess skin (although I know it will not completely prevent it). Do you guys have any suggestions?

What Earl said WALK!!!!!! after doc releases you, you can begin to SLOWLY build a routine. But after just walk and rest, get your head straight, walk, learn to use the tool, walk.
