But guess what... nobody else really notices. Don't concern yourself overly with it. Training one side more than the other doesn't work as well as you would think. Increasing volume on one side gives and takes away, both, because of diminished returns when overtraining. So stop training the stronger side? No, no, no! Just train, train both sides equally, and it will either correct itself or it won't. If it doesn't, chances are you are the only person that will notice.
