I have had this question for years! All I want to be able to do right now is to be able to do a double back flip on the trampoline AT THE QUAILIFIED GYM I GO TO. I have the height and the form and I can even do one and land on my back, but I am so scared I will start flipping and won't be able to stop and will break my neck or something. I am afraid I won't be able to find the spot of where to stop and put my feet down. Anyone else have this problem? How did you get over it? I would love a coaches input! REPETE I AM DOING THIS SKILL AT AN ACTUAL GYM WITH A COACH NOT ON A HOME TRAMPOLINE UNSUPERVISED!
