A few years ago I tore my rotator cuff in my right shoulder and required surgery... and in the process of rehabilitating myself my left pec grew a lot bigger than my right. Is their a way to fix this? The only thing I fear is If I only train my right side to catch up with my left, it can cause a huge strength imbalance because even though they are different sizes they are equally strong right now. As for my shoulders/triceps and everything else... they're all 100% symetric. Any advice or recogmendations would be hugely appreciated, thanks.
