Go into a room where you have furniture that does not break like a soft sofa or outside where you have bushes and trees and close your eyes. Roll from place to place without opening your eyes and correct your rolls when you bmp into things like the wall, a tree or a rock. Learn to roll with care and to protect all of your parts as best as you can. Move slowly because if you are alone and with a broken leg in the woods it is a good bet you will not see your friends again.
Afterwards note how you placed your hands and legs as you were going down and rising to see what fear and awareness bring out of you and use it to your benefit. Add to this to create your own way of movement.
