Recently I've been notcing an imbalance in the muscle definition on my right side compared to my left side. When I flex, left always looks just slightly bigger and just slightly more defined then the right. When I am at the gym I always struggle not to have my left overcompensate for my right. On dumbbells my right always fails first (obviously I stop at that #) Here's what concerns me most. I have always favored my left side. I have a crooked smile, my right eyelid droops a bit more then my left. My friends say that I drop right shoulder a bit in my posture. But all of this is hardly noticable unless you look for it. That said, what do you guys think I need to do at the gym to stay balanced? Should I start doing more reps on my weak side? Has anybody else struggled with this, or even favored one side in every day life? I don't think this is worth seeing a neurologist over, I was just wondering if any of you had some similar experiences or advice.
