How to lose weight when working out a lot and gaining muscle weight?

I work out every morning for two hours at a strength and conditioning camp which includes weight lifting which= tons of new muscle= more weight!!!!!!!

This camp is four days a week, 2 hrs a day.

I want to lose weight though, not gain wait. So how can I keep gaining this muscle but loose weight in other ways?? Because I am a flyer for cheer and if i weigh too much I will wiegh my bases down?!!?!
