Lisa,
I can relate with the skin hanging down when you are in push up position! It looked awful. Only a few weeks ago did I noticed it. I am actually fit, and with clothes on, my stomach is VERY flat. Boy, oh boy, when I am in the push up positon, and looked inside my pants -- watch out! FYI, I have twins with the combined birth weight of 12 lbs (and I am very small/petite)! I think tummy tuck is the only way for me, but I am not considering it since I don't want to risk my life for a elective/vanity surgery. I guess I have to learn to live with it.
