Do a handstand and push down hard against the floor as you extend your body up toward the ceiling as far as possible.
Now stand up and raise your arms, hands turned in and push up and extend the same way you just did in the handstand, just as tight, just and strong.
Now roll back tight and hollow and FAST, arms staying at or behind your ears, and continue the extension and pushing arms away from your center. Lock your elbows and do not bend them regardless of whether you make the back extension to hs or not. If you do not make it up roll back down through candle to your feet and try again. Respect the tight hollow, locked elbow position and do not relax or loose the shape just to "make" it up.
Use an incline and do one on the incline, one on the floor (whether or not you make it up), back to the incline, repeat.
What I tell our gymnasts that seems to help is that the floor/carpet will TRY to bend you, it will try to make you crumple up. You must be tight, pushing and ready BEFORE you roll back so that you are pushing against the floor/carpet before your hands even get to it if you want to make it up. If you wait until you feel the floor/carpet with your hands you are too late and the floor/carpet will win.
Good Luck!
