I am writing less and less as there are fewer questions that I have these days. My hands are quite smooth as I have prefered them that way. Heavy negatives condition the hands and part of that is the heavier weights callous the hands better than standard reps alone. I wonder if the callouses made from heavy deep set negatives along with CCS distance negatives doesn't help hold the dogleg handle in the palm better or keep the handle in your palm from sliding around. Robert I know you mentioned that you shave/file off your callouses every few days. For myself, I wonder if I should actually do this. Also this could explain why I have had so much success with grippers after doing high reps-my hands use to have a calloused wall to help brace the gripper. What do you all think about this?
