Thanks for all the help, few questions: what are zotterman curls, and will Coc also improve my grip strength? I already do wrist culs and sometimes behind the back barbell culs for my forearms and get a good pump, but my forearms aren't growing as fast as the rest of my body and my grip strength has been static for a few months-this is most noticeable wheni do pullups or shrugs. I'll try to hold weight/hanging from the bar techniques you guys suggested but won't Thor's hamer work my shoulder more than my forearms? Once again thanks
