Here's how i think of it when i do it. I think of getting, low, carving in but not as much as it seems most people in this thread do, i pop a little before the knuckle, and once i feel like my feet leave the snow I act like im throwing my body backward (almost like a 180 to stomach drop on a trampoline) and reaching back to drag where my feet just left. From there i pretty much just think about putting my feet back under me. It did take me a while to get, but when you do it right your feet should sort of just naturally come back under you
