As far back as I can remember, before I even started training, my left shoulder cannot externally rotate as far as my right shoulder. In fact, I can’t even do wall slides properly with my left arm and it seems like barbell incline pressing is harder for my left side. Furthermore, back squats are out of the question due to lack of flexibility in the left shoulder.
Should I continue doing external/internal rotation exercises, wall slides, scapula pushups, and face pulls or should I see a sports physician?
Is this a problem that can be fixed with rehab exercises? Finally, should I be stretching the shoulder? Responses appreciated.
