Okay so I was watchin the documentry on Greg Valentino (I know why waste my time but I found it interesting and theres not enough bodybuilding shit on T.V) and noticed a guy in the background doing what seemed to be hammer curls, However at the contraction point he was rotating his wrists (like you would turning a door knob). Anyone know what these are, what they do, are they any good?
