Question: What exercises are recommended for keeping the shoulders strong and agile?
The most important shoulder muscles are the four rotator cuff muscles - the subscapularis, supraspinatus, infraspinatus and teres minor muscles - which connect the scapula to the humerus and provide support for the glenohumeral joint. When the rotator cuff muscles are weak or injured, it debilitates the major functions of the entire shoulder. Stretching and strengthening exercises of the rotator cuff should be the focus of your exercise in order to keep your shoulder strong and agile.
