shihonage - can't help on this. I'm trying to learn how not to bust up my arm.
grab elbow with the other arm and pull elbow toward your body. also bring head toward wrist. i picked that up from Ellis Amdur. worked the like a charm. nobody has been able to throw me into a shihonage breakfall. besides, ukemi is about protecting your body, not abuse it and won't allow others to abuse your body either.
