I've been a size 8 my whole life and didn't put on any weight while pregnant (except for obvious additional human being in belly). My figure went back to normal pretty quick except I still have a Mummy Tummy that I can't seem to get rid of. My stomach muscles are firm again, there's no excess fat, it's just a lingering bunch of saggy skin that doesn't want to budge. WIll this go eventually or is this permanent? Anything I can do to tighten it up? I've never heard of a skin-toning exercise
