I think it's pretty hard too :cursing:
But I found it easier if you do the htw fast, and go abit under the ball after it, then turn up and do the atw instead of just htw and hit the ball when your leg are going down you should go down without hit the ball, then go up (don't hit the ground)and hit the ball on the way up and then do your atws.
Does you understand a shit of this? Sry for my bad english :cheers:
