I`m 14.I have really awful thighs and I mean awful I think this is because I have a big bottom that does actually stick out. My legs from the knee down I view as "chubby" only they`re made to look even more stumpy and fat by my thighs and bottom. I do a lot of sport; dance, swimming, diving, and skating and I eat a lot of fruits and vegetables. I have stopped eating “junk food" (occasionally allowing myself a packet of crisps/some chocolate/ a few biscuits) and finding that aspect quite easy but I see no changes at all and if I`m to dance it is essential to have toned and healthy looking legs which I definately don`t have. Is there any help at all? I`ve tried a lot of excersises from the internet but they don`t work. I should mention I have stretch marks at the top of my thighs.
