You're ahead of me--I don't have surgery until May 3. But I thought I'd share this. When discussing exercise with my dietitian, I mentioned how much I hate walking--anything but walking, which I find so boring! We talked about what I do like and when I told her I had a pool I enjoy, she was excited. She said they've found a remarkable improvement with skin issues with patients who swim or do Water exercise. I don't know if you have access to a gym, but you might want to try a water aerobics class. Find a good one--some are pretty lazy, but you can get an energizer class that will really get your heart rate up, will provide resistance (from the water), and apparently help protect against loose skin. I don't know if it'll work, but I know I'll be in the water as soon as I'm cleared to be.
