I know this sounds like common sense but I see a lot of people at the gym training through an injury. Don’t get mistaken by my words. We could train AROUND an injury, but not the injured part itself. I see guys complaining about shoulder pain but then their buddies would still urge them to work in. In all honesty, I think this is really stupid because you can’t hold your friend accountable for it. Especially if it gets worse. Injuries cause by pushing are the worst as guys really like displaying their strength on the bench press and shoulder press. So heed my words. If it hurts, don’t train the injured body part. Have it checked by the doctor, do your own research and fire your buddy.
