So, I'm using a trampoline, and can do a front tuck, front half, and probably a front full (whatever I'm doing isn't hard, and feels like a front full, but there's no one around to watch and verify...I need to find a video camera).
Going backwards, I can very easily do a back tuck (even on ground, no problem), and I can do them way high up, and way laid out. I might even be able to do a double...I've tried to twist for a back half, look over the shoulder, do something with my arms, but nothing happens!! How do you start twisting? What should my arms be doing?
