Ura Zuki

Note: zuki is a punch with a closed fist. The pictures below show the setup.In this case the fist starts pronated and ends up supranated, which is the reverse of oi zuki. It is critical in this technique that the elbow passes close to the torso, and does not flap about like a chiekn wing. Also, the strike is to the centre of the opponent, with the striking arm's elbow reinforced by the gut.
