First of all, I'm not huge on bicep exercises - I do two bicep exercises a week, everything else is from pull movements on other lifts. I'm 6' tall and about 185. I'm a skinny guy, most of my weight comes from my legs. On arm day I do two bicep exercises, preacher curls w/ bar and hammer curls. Preacher bench curl is 100lbs at 5x5's and hammer curls with 55lb dumbbells @ 5x5s. Here's a front and rear pic of my bicep for reference: During my last few workouts I've been experiencing severe pain in the outer part of my forearm, when at the bottom of the negative of each rep the outer tendon of my forearms goes crazy. When I set the weight back down it feels like my outer forearm has been pulled like a rubber band and is slowly receding back to normal - then I'm fine. Pic of forearm: And this is the section of my forearm where the pain I'm describing is: It was so bad tonight that I just stopped lifting heavy and went real light - still minor pain though. I've been doing 5x5's for about two months now and getting some good gains - I don't know if my forearms can't keep up with my biceps or what. I'm out in Afghanistan and the only doctors here are special forces medics who will tell me "suck it up or stop lifting." There aren't exactly sports medicine specialists out here. I'm going back home in a week and a half and I'll have someone check it out - but in the meantime I was hoping someone here might have some experience/advice for me. Thanks in advance.
