Help. My left leg is a lot more muscular than my right. The left hamstrings are thicker and the left adductor is bigger than those on the right. It's been this way from before I lifted weights. I think it came from playing a lot of basketball as a kid and doing running jumps off my left leg. But that was 15 years ago.
I've been squatting and deadlifting since and the imbalance is still there. What can I do to correct it? Even now after a couple days of heavy deadlifting and squatting, my left leg is feeling more fatigued. When I'm pushing through sticking points, my left leg contracts harder before I can stop it. The muscles there are always taking over the work.
