I don't know what it is called but there is one bicep one a frined told me about where you start at the hip, and then curl towards your chest on the opposite side, and you hold for a second or two and the release. Anyone know what it is called?
Also I do the normal curls and the ones where you tweak at the top. Can anyone suggest any other ways (w/ descriptions, # of repetitions and sets) to build mass? I usually do 1 set of 20 normal biceps curls, with 15 lbs but that hasn't seemed to help me too much
