Thanks guys, ill experiment with the chin grip. Seems i did feel a little bit better going wider on chins, which also helps me on barbell curls.
Blaire, i never thought about shoulder flexibility. This wrist hardly bothers me in most movements, but mostly on chins and curls with a flat bar. I also have a little elbow pain on this side i thought was tendonitis that comes and goes. Does that sound like shoulder mob. to you or just wrist/forearm?
