Alex and I will be beginning four-part series on the shoulder. Injuries to the shoulder are the most common reason I see CrossFitters in my office. Alex would agree that most complaints he hears are about shoulder pain or tightness. A healthy shoulder joint is dependent on good shoulder mobility, scapular stability, rotator cuff strength, thoracic mobility and good mechanics/form. Our goal will be to address all of these so that if you follow along during the 4 weeks, your shoulders will be more prepared to tackle our daily WODs.
This series will be broken down into 4 topics - stretching, activation, strengthening and integration. We ask that you focus on the stretches, drills and exercises we demonstrate each week.
The most common injury to the shoulder is called impingement. Many of you who are complaining about pain in the front or top of the shoulder, also pinching sensations, are likely dealing with impingement. What happens is the tendons of the rotator cuff, likely the supraspinatus, get pinched in the shoulder during any overhead movements. You can feel pain during pull-ups, wall balls, KB swings, and snatches, for example.
The role of the rotator cuff is to keep the head of the humerus (shoulder bone) centered in the joint during any movement. When the rotator cuff gets tight, weak or imbalanced, it can't do it anymore. As the tendon gets pinched, the more pain you are going to feel.
This week we will start on stretching and mobilization. Follow along with the video and perform daily.
Stay tuned for next week when we cover how to activate the weak muscles around the shoulder.
