Back View – notice shoulders are set
A very common problem in the clinic is neck and shoulder pain. Every type of athlete and avid exerciser will likely experience shoulder pain at some point in their career. Yet so often at the gym I see shoulder exercises done incorrectly.
Most people do not know that the rotator cuff is an extremely important muscle group and what it’s purpose is. This shows up in exercise routines as either poorly executed exercises or lack of stability exercises at all.
The rotator cuff is the primary stability for the shoulder. The muscle group (containing four muscles) holds the humerus into the pocket of the shoulder blade. Yes, these two bones make up your shoulder! ** side note: if your shoulder blade is winged or dysfunctional you will have shoulder weakness** If your rotator cuff muscles are not activated, your big traps and deltoids and biceps and triceps and pecs and and and etc have to hold the joint together. These muscles need to save their energy and strength for moving objects, turning door handles, getting out of bed, sitting in a chair or any number of upper body movements. With a properly engaged rotator cuff, these muscles will not tire out so quickly leaving you with achy, heavy shoulders or neck pain.
Side View – notice the elbows are under the shoulders
The muscles in the rotator cuff (infraspinatus, supraspinatus, teres minor, and subscapularis) hold your posture, internally and externally rotate your shoulder, and initiate lifting your arm. I have pictured the most popular rotator cuff exercise designed to strengthen the external rotation of the shoulder (infraspinatus and teres minor). Since we spend so long in internal rotation (sitting at a desk or using our smart phones), it’s important to restore this movement. When our external rotators are as strong as our overworked internal rotators, we are in balance and posture improves.
The external rotation exercise is commonly used with a resistance band.
Front View – notice the wrists are straight and the elbows have not moved back
The important points to remember are:
- Keep your posture
- Keep your elbows touching your sides in the rotation
- Stay away from letting your shoulders fall forward during any point of the movement
- Do not squeeze your shoulder blades together
