Hey forum,

I know many people have this problem; one arm is noticeably smaller than the other! My right arm is far bigger and stronger than my left. It is odd because I train them the exact same way. However, I am right handed and so favour my right arm more. I'm also a drummer/guitarist which means I use my right arm a lot more during those activities. *insert childish joke about masturbating here*
But seriously, this frustrates me to no end! Any suggestions/solutions to help correct this?
