wow matt, thanks for taking the time to write that out!
i'm slowly working on correcting it all.
rather than muscling everything, i'm just working on the individual roundoff and backhandspring techniques and form first.
when you said that doing the snap down, the feet should land closer to where the hands touched the ground, that doesn't make sense to me. i thought that the feet should travel much further back.
also, when you said that a snap down from an elevated surface could result in a back tuck "picked" with legs straight, did you mean piked? and is this off a sprung floor?
thanks for the awesome post!
