Hey guys, I haven't posted for a while, but I went to the gym for the 3rd time this week, and I've been noticing everytime I work out (bicep curls), my left arm always seems "bigger" than my right arm. It seems like it's been worked more than my right, except my right arm is always the 1st to tire, and I feel like I can lift all day with my left arm. Is it the form that I am doing with my right are that is making it harder to do and not using the right muscles or what? I don't know what to do, but my left are looks a lot bigger than my right, and I am right handed.
