BACK HAND SPRING HELP?

I keep bending my arms for a standing back hand spring I really need help! I have It by myself it's just hard!?

• I can do it by myself and I practice on a mattress on the ground so I can perfect it and stuff but I sit back into it and my arms hit the ground and they collapse and my head slightly touches the mattress and I flip over and land on my feet! I keep trying these "blocking shoulders" drills like the handstand and you jump with your hands and hit the floor know any other drills? I used to have a really good back hand spring last year I just re-learned this and I can't find out how to do it. I don't take tumbling classes, I don't plan to I'm self taught. Don't direct me to a spot or coach because I don't need a spot, I won't say I don't need a coach but all I need is this backhandspring. I can do it in perfect form on the trampoline too. Please answer this. If you can't, please direct me to another "answers" site on the web. Preferably cheer related.

• Answer:

  Lock your arms, and seriously think about doing one with a spot because spots give you real advice and help you a lot. Make sure your hands are by your ears. You can lift weights, do pushups, pull-ups, handstands against a wall. Good Luck!
