Well fuck you then:) Just kidding. On a backflip, you want to be sure to commit fully. You'll always overotate when you sling the flip and stiffen your body in air. You want to be able to control the speed at which you come around. Approach the hit, pop and throw your body, especially your hips forward and up, your head should be all the way back and looking for the ground. Again, you don't want to be stiff, because if you threw the flip too hard, you want to be able to 'pike' or break at the waist, stalling it out and arching your back while spotting the landing. See Seth in Focused. If you throw too lightly, you are going to want to pull you legs in hard, speeding up the rotation and allowing you to land safely. As long as you commit and allow your self to be relaxed to correct yourself mid-flip if need be, you'll be fine. Do gainers off of diving boards or backs on a tramp. Take it to the snow and later start to add grabs or a tucked body position. Good luck.
