XD Please tell me you're joking. If not, I'd suggest practicing keeping your body up in a handstand- that's all that is and barely for a few seconds, while kicking the legs out from behind you like trying to do a .... very awful attempt at getting into a handstand that looks more like a push up. You can practice hand stands against a wall, do push-ups I suppose... however he only pushes back on his shoulders and his thighs go up while his legs push out, then he tries to carefully let his chest down before his knees bend and his legs follow through; but it might be wiser to be sure to stretch/and/or be used to using your upper body in that way. Don't want to injure your spine. ^^
Helps to have a mat, but I'd highly suggest insuring you learn to do handstands too (against wall/eventually walking on hands too), and have a spotter. You can watch vids all you want but just because they tell you how to have your head-- doesn't mean when you're throwing your body into the air trusting your hand's strength means you'll get it right on the spot. If hand stands, even against the wall become difficult, beginner cartwheels, push-ups.. and yoga should help--(longer you go without stretching the less limber your body until your body re-adapts). Being a gymnast when I saw this move for the first time... I didn't need taught. XD Same can be said about most moves; when you're used to it... some stuff just seems child's play. What I had NOT learn how to do is kick-flipping off a wall over someone, but I knew someone who could. Now THAT was beautiful.
