When curling anything other than free weights i.e. flat bar bicep curl or bicep curl machine (unless it has a pretty angled thumbs in grip) I get terrible pain in my forearms.. i've tried wrapping, gloves, watching my form... but nothing seems to fix it... I'm not doing a lot of weight but going lighter does help... but how do I help my biceps strengthen if me forearms cant handle it? any ideas?... I've been using a rope attached to a weight wrapped around a stick and rolling it up with my wrists (think motorcycle throttle), simple squeezing workouts with my hands and wrists but it just doesn't seem to help
