Well i made a replay posing over uke's arm but is not gymnastic.
Well i'm gonna try adn see what happens.
edit : Well I tryed it , and it wasn't that hard , trough don't put attention at me(it's very unrealistic and didn't put effort on it) put attention on uke(becos I putted effort , and tryed it to be relistic)
I just tryed to me to give him a push to flip but didnt move anymore , I moved uke a bit more.
