I am going to add to the chorus of people saying she should lose some weight. It is clearly not only muscle mass she's adding, though there's probably some of that, too. You can look at someone's face and tell if they're gaining fat or muscle.
She's not going to be able to have a whole lot of time to work on her spins and performance and other things while she's retooling all of her jumps, but she *can* find the time to get her weight under control.
She's a junk food junkie, if she just cut down on that it would help.
I've always had a special spot in my heart for Caroline, but right now I'm much more pessimistic about her skating future than ever before. If she doesn't get her weight under control very soon, I think this might portend the beginning of a rather rapid finish to her skating career... just in time to attend college.
