Hello everyone! I've been going back to the gym for a while now. It seems that my left muscles are slightly bigger than my right one (Biceps and chest). I am still in the early stage so when I grow bigger, it will become more obvious. I am a right hand guy by the way. Even 2 years back when I was really active in body building, my left muscles (biceps and chest) are always bigger and have more cut.

Am I working out wrongly? Is it my genes? How can I get my muscles balanced? Please help!
