My stomach is just horrendous. It's so flabby and just overall unpleasant to look at (dressed or not). The worst thing is that I am 20 months post-partum so I think it may be too late to do anything now. I've tried to check for diastasis recti but I can't tell whether I can feel a gap or not. What can I do to help reduce the size and the flabbiness of my stomach?
