Hi, My 11 year old son is doing gymnastics. He can, when he's lucky, do 3-5 circles on mushroom. His coach for level 3 says he's the best in level 3 at the extension, etc. A couple questions: How can he get his body raised higher? Right now it's pretty low. We were thinking a bucket+mushroom+diy EGE setup, but we wanted the community's input. How can he increase volume? His main problem is that his hands move weirdly across the mushroom and he basically like flies/falls off. he's not fast, I don't think speed is the problem. What upper body conditioning is there to stabilize this hand movement and keep it controlled? Help is appreciated Thanks
