Yeah it isn't in my shoulders as much as where the bicep connects to the shoulder and down the side of the arm. I just looked through some older posts here and a common consensus was rotator cuff.
I haven't done any bicep work in about a year. I only do rows and pull ups so I'll give that a try.
Nice thanks a lot!
Excellent article, I find that externally rotating my arms between sets helps, I'm going to try these out.
