It hurts him above the wrist, half way to the elbow. At the moment I've got him orthodox. Working the shat out of the left.
It is the right hook to the body, that seems to hurt him. Here is the scenario, We start off working on his feet and head movement. We then go to the heavy bag, get him moving the head and popping off a combo to the body doubling up on the right body then head, snapping a left jab and stepping out at an angle. I can see when it hurts him generally on the first right to the body. He goes through the set then complains. When that happens we go to shadow boxing and the rope. We got through this routine for about half an hour at a time.
He hits hard as shat. I have niticed that the bottom of the bag is allot more solid than the middle and top. Could this attribute to the problem.
