when i lift biceps...my forearms cant handle the weight i need to get my bi's bigger. Therefor, my bi's will not grow. The reason my forearms wont hold the weight is because i get horrible forearm splints, just like shin splints. As soon as i let go of the bar/dumbell, the pain just flares up. The most logical reason is to build my forearms up to hold the weight, but will this take away the splints? and i work my forearms twice a week by taking the 45 lb bar andturning my palms up in front of my knees and rolling the bar up, then back down. I can usually get 40-50 reps of this, but my forearms dont seem to grow. Should i use more weight with this exercise or use a different excersize? is there anything i can take to reduce the pain? please help! its extremely frusterating!
