Whenever i do barbell curls or even with dumbells my right bicep gets worked right but my left arm, its the forarm that gets worked and the bicep only takes some of the weight. I have been doing the curls with my elbows in by my side and i just dunno what to do, my left fore arm is noticeably bigger than my right and my right bicep to the left. Any ideas or suggestions as to whats going wrong? Also when i was doing reverse curls on the BB same thing, worked my right arms bicep more than forearm and on the left arm, it was the forearm that was lifting and not so much to biceps :/
