Some great advice for strengthening the rotator cuff muscles over at “The Human Condition”.
Before we go any further, lets talk about what the rotator cuff is. Surprisingly, a lot of people including trainers, don’t know. The rotator cuff is a series of 4 small muscles which include the Supraspinatus, Infraspinatus, Teres Minor and the Subscapularis which originate on the scapula or shoulder blade and connect to the head of the humerus at the glenohumeral joint. The purpose of the rotator cuff is to dynamically stabilize the shoulder joint during dynamic motion. Think of it as the “Core” for your shoulder.
So it would seem that by simply strengthening these 4 muscles we can correct any rotator cuff issue that we have, right? Wrong. we’re missing a big part of the picture here, and that big part is Scapular Stability. Our scapular stabilizers include the Rhomboids and the intermediate region of the Trapezius. In a strength program designed to strengthen the rotator cuff, if these muscles are ignored it would be like trying to build the Great Pyramid of Giza from the top down… Good luck! Incidentally, these muscles are also responsible for maintaining correct upper body posture… you can begin to see where all of this is going, right?
