Sarina,
Whoah, when did you start this process and how often did you do it? Every day? I have never heard of this and am incredibly fascinated.
Lovie,
I went to the doctor once with similar questions about stretched skin. He told me that there was no hope beyond surgery, which is a bold faced doctor lie. Along with exercise and diet there has to be a good skin care regiment, like Sarina talked about, and I tell you those "cellulite" creams that are over the counter really don't do much for anyone, unless they are already close to flawless.
There is lots of hope, however, as my mom and I started a series of core workouts together (beyond pilates) and what I can say is this: that it is the amount of reps that shows results, not necessarily the increase in weight. more reps equals smoother muscle, but more weight equals bulk, which may not be a good thing if the goal is to get skin to stretch back.
anyhoo, that's my 2 cents. best of luck!
