I am a 14 year old ballet dancer and am looking for ways to improve my endurance and conditioning as well as reduce the size of my hips/thighs.  Right now the only training I take is ballet and point class for about 2 hours a day.  I was thinking of jogging or running to help endurance or perhaps swimming but I am afraid these exercises will just make my thighs grow even larger.
What cross-training advice do you have for serious ballet dancers that can help build aerobic endurance?  And what can I do to reduce my thighs and buttocks?  Am I just a victim of genetics?
