The wall collapse: Start from the push up position and one at a time relax one arm totally so you collapse to the ground and see how your body and nature finds the form there. Than place your legs or one leg later on on the wall at a low hight and repeat the drill. Go higher and higher (keeping the walls clean mind you !) till you are collapsing from a hand stand and than move to regular rolls on the ground and see what is new and how you can nagotiate your way without the need for support. Another way to do this is to roll from standing to floor and back with hands clasped at the back and learn to keep moving always the hard way
