Uneven arms??

[snfu]

Hey everyone!!
I was just wondering what to do for training.. I'm a carpenter and my dominant right arm is noticeably bigger than my left arm, since it's always got a hammer, drill, or saw..
When training, should I just use heavier weights for my left arm or the same weight more reps or...?
Thanks!

i would try to just build the muscles in my left arm.

muscle mass=heavy+low reps

do strengthening/conditioning exercises for your right arm. higher rep+lighter weights to keep it in tip top shape while the other one catches up in size.
