My Biceps are sore right now and I did chest/shoulders yesterday. I did DB flat bench, incline bench, decline bench, machine flys, DB shoulder press, DB palms in shoulder press, front raises, and side raises.
Why could my Biceps be sore? They are sore only in the position where the hand is nearly touching the shoulder. I did doorway stretches for the chest after the workout; could that have anything to do with it?
