Maybe I am over thinking things, but the fact that my left arm is slightly weaker than my right bothers me at times, therefore I mostly stay away from exercises that use single arm, such as single barbell curls. For instance, when I do concentration curls, I can do my 12 reps, but usually can only get 10 or 11 with my left arm. Is this a concern? Should I not worry about it or maybe do some forced reps with left to get it the same?
