I think I fooked up my right rear deltoid a little bit. When reaching up under your armpit towards the shoulder blade, that area right under feels pretty tender and sore. I believe that is the rear deltoid right? In between shoulder and arm, above the armpit. Makes my shoulder feel hurt too. It happened during clean and press. Felt it already at the clean. I believe I used my arms too much during the pull in stead of keeping them straight and shrugging up yesterday. Been practicing the movement again some today using a broomstick. Felt it a bit since the entire area is tender but doing them like that with better technique should keep me clear I hope. What u guys think?
