I know that lifting heavy weights is the key to building muscle, and I have heard here that people really are wasting a lot of their time doing 3x15 of low pound weights all the time in the gym. Anyway, I agree with that, however I'm not sure what I feel in my forearm is good. It feels like a line going from my elbow down towards my pinky, but it stop at my wrist. I dunno if I'd call it pain (I'm a Marine, pain just feels like progress to me), but I'm not stupid enough to not ask for advice.
I am 23 and I don't do any crazy routines or anything. the heaviest I go is with weights I can do 6x5 with. I only feel this when I'm doing my biceps.
I took a break for a few days and that helped, I lifted some weights that I could do 3x12 with and it was fine, but when I tried to heavy up I could start to feel that tendon, or whatever it is, sending my brain signals.
Should I just take a week off on my biceps/forearms or what?
