@anatomyunseen1: One side moves freely… the other gets trapped. And the scary part? It happens every time you raise your arm. No warning. Just pressure building up in a tiny space. Rep after rep… until your shoulder starts talking back. That “pinch” you feel? That’s not normal. Watch the right side again — this is where it begins. #shoulderpain #rotatorcuff #gymmistakes #injuryprevention #anatomyexplained
