i've been working on extensor action today for the first time. It certainly seems to make my whole power package feel more solid. I also get the feeling its placing greater control over my right elbow and stops any tendancies for it to go over the plane. I hope these are signs i'm executing it correctly.
My only slight concern is as a swinger is there anyway way it can inhibit the left arm blast of the chest? I say this because i didn't feel the same sense of looseness and feedom through the ball as normal.
