well i'm pretty sure it's not from cheating when i'm doing curls. i have read all about how cheating doesn't help you grow on these boards, so i use enough weight so i only move my arms. ericthegreat11, what are behind the back forearm curls? i have been thinking that maybe my forearms are fairly weak and i should concentrate on them more, or follow the idea of working w/ weights that i can to 8-10 fairly easily, which sucks because i know i probably won't get as much growth from that, but oh well. i think i will stop doing preacher curls too for awhile, because i can still slightly feel the pain today while doing certain things. does anyone actually know what this is, or is it basically just weak forearms, or weak bone structure in my forearms?
