Im not that strong, only been lifting for several months, but have noticed nice results. Today I was doing seated cable rows with the max weight I could do for 10 reps (150lbs) and when my arms were extending, it felt like the weight was trying to pull my arms out of the socket, and there was some slight pain as well.
Is this a muscle imbalance? Or does this happen because I hyperextend? Should I do rotator cuff workouts?
