i'm also a former gymnast and i would like to say that anything is possible on a trampoline. as a gymnast you are taught how to tighten rotations to have the most effective spring possible. this is just an example of a well trained man who throws ridic rotations. his stuff in the beginning is amateur, layouts are not hard to execute even on floor. however his front rotations are insane.
i love a good pit/tramp sesh.
