Start this drill with your hands naturally at your sides and hit each other all over noting and sharing how each strike feels and moves you. Try with open hand, fist, elbow and so on. Next raise the arms from the elbows to the common ready stance people take and repeat the process noting changes in effect. Next change the footing and repeat and than sitting and on the ground. Finally do this as you walk and move differentry on the ground and you will learn how our frame and tension changes as we move mass from limb to limb and how to relax more so we are free to move better.
