A viewer asked a great question about the reasons why serratus anterior might shut down or become inhibited. I’ll combine my love of Logic’s music with my understanding of this awesome muscle to try to answer his question. It’s important to know that serratus anterior does not work alone in optimal positioning the shoulder blade. Upper and lower traps are critical. However it struggles when the pecs and the lats become dominant. This pattern is very common in Rock climbers, CrossFitters, throwing athletes, racquet sports athletes, and swimmers. Activating the muscle is simple once you know what you’re looking for. Then reinforcing this in your warm-up is a nice way to assure that it participates during activity.
