I have been banded for 3yrs this coming June. When I started exercising post-op I tried walking first. But due to Lupus and Fibromyalgia it was very hard on my body. So I began doing Water aerobics. I joined a class and did an hour 3 days a week. It helped soooo much and I was able to do things in the Water I couldn't out of it. I was able to drop 20-30 pounds. I was then able to add walking and other things back into my workout.I am now down to my goal and traning for my first half marathon...
Good Luck with your weight loss
