Top Exercises for Girls | Shoulder & Collarbone Exercise at Home in 2 Week

Most people are so focused on working the big muscles in the shoulder like the deltoid and muscles in the upper back and chest that they fail to focus on the smaller rotator cuff muscles that give the shoulder joint stability. Your rotator cuff is made up of four muscles: subscapularis, supraspinatus, infraspinatus, and teres minor. These muscles attach to the upper portion of your humerus bone and work together to stabilize it. Along with stabilizing the humerus, these muscles are involved in the abduction, adduction and lateral and medial rotation of the humerus.
By strengthening the rotator cuff muscles that support your shoulder joints, you lower your risk for sprains, strains, instability, and dislocations that can take months to heal and, in some cases, leave you with chronic shoulder pain and the inability to play your favorite sport. Keeping these muscles strong and healthy is essential as rotator cuff tears have ended many an athletic career. You may not be a professional athlete, but you need strong, injury-resistant rotator cuff muscles and stable shoulder joints if you plan to weight train or participate in sports.
