I love concentration curls but my left arm is stronger than my right on this one exercise. For example when doing GS Back Shoulder Biceps, I use a 12lb DB for all the sets with my left arm, but with my right arm I have to drop down to a 10lb for the last bonus set. Is this ok to do? How do I "catch up" my right bicep? Thanks~ Mary
