My name is Aaron, and I'm 23 years old. I've been doing exercises for 1.5 years but I have one problem related to pain.
When I am doing exercise of biceps, my shoulder starts hurting prior to biceps pain, which means I cannot feel biceps pain. What can I do to avoid this shoulder pain? I have asked three or four gym trainers, but have not received an answer yet. The same problem is happening with my triceps and back, and sometimes with me chest. I checked my exercise position with our trainers, and with online Youtube trainers, and my position looks accurate. And I have tried low weight, e.g. 5 kg for biceps, but I still get the same pain with my shoulder.
