So basically whenever I put chin ups into my routine, I get a very annoying upper back pain in the shoulder blade when my back is against something(sitting in a chair, laying down, etc.). The pain goes away as soon as I switch to something like pull ups.
Recently I have been doing pull ups only. Yesterday I did 2 short sets of chin ups(along with pull ups), and sure enough after I left the gym the pain came back when typing up my workout.
Am I somehow doing this exercise wrong? Anyone have a similar issue?
