Rotator Cuff...What is it and Why is it important?

The Rotator Cuff is a group of 4 muscles that give our shoulders DYNAMIC STABILITY by keeping the humerus in the glenohumeral socket during daily shoulder movements to optimize the shoulder range of motion and strength.


These muscles are active ANYTIME we use our arms out in front of us or to the side.





The 4 Muscles that Make up the Rotator Cuff include:

  • Supraspinatus: Most active lifting the arm to the side or forward, and stabilizes the humerus during pressing movements.

  • Infraspinatus and Teres Minor: Most active when we rotate our arm outward (external rotation), lifting the arm forward to the side and stabilizing the humerus during pressing movements.

  • Subscapularis: Most active when rotating the arm inward (internal rotation), lifting the arm backward and stabilizes the humerus during pulling movements.


Are you dealing with nagging shoulder pain??


It is often due to either an under trained or strained rotator cuff!! These muscles need to be strengthened consistently even if you already workout. There are specific exercises that you can use to address these muscles and keep your shoulders functioning optimally.
