Shoulder discomfort can significantly impact daily activities, from reaching overhead to lifting objects. A common culprit behind such discomfort is the subscapularis muscle—a key component of the rotator cuff responsible for internal rotation and shoulder stability. Weakness or injury in this muscle can lead to conditions like shoulder impingement, characterized by pain and limited mobility.
At Hand to Shoulder Associates, we emphasize the importance of targeted exercises to strengthen the subscapularis and alleviate related shoulder issues. Our team of board-certified, fellowship-trained specialists has developed a comprehensive exercise program designed to restore shoulder function and reduce pain.
- Understanding Shoulder Impingement and the Subscapularis
Shoulder impingement occurs when the tendons of the rotator cuff become compressed or irritated as they pass through the narrow space between the top of the shoulder blade (acromion) and the upper arm bone (humerus). This condition can result in pain, weakness, and limited shoulder function. Strengthening the subscapularis muscle can help alleviate these symptoms by improving shoulder stability and function.
Targeted Exercises for Subscapularis Strengthening
Our recommended exercise regimen focuses on stretching tight muscles and strengthening the subscapularis to enhance shoulder mobility and reduce discomfort.
1. Pectoralis Stretch
- Purpose: Relieves tightness in the chest muscles, allowing for better shoulder movement.
- How to Perform: Stand beside a doorway with your arm at a 90-degree angle against the doorframe. Gently lean forward until a stretch is felt in the chest. Hold for 30 seconds and repeat 3 times on each side.
2. Passive Horizontal Adduction
- Purpose: Stretches the rear shoulder muscles to improve flexibility.
- How to Perform: Bring one arm across your body at shoulder height. Use the opposite hand to gently pull the arm closer to your chest. Hold for 30 seconds and repeat 3 times on each side.
3. Side Bending Neck Stretch
- Purpose: Alleviates tension in the neck and upper shoulder region.
- How to Perform: Sit upright and place one hand on the opposite side of your head. Gently pull your head toward your shoulder until a stretch is felt. Hold for 30 seconds and repeat 3 times on each side.
4. Shoulder Blade Squeeze
- Purpose: Strengthens the muscles between the shoulder blades to enhance posture and shoulder stability.
- How to Perform: Sit or stand upright. Squeeze your shoulder blades together, hold for 5 seconds, and release. Repeat 10 times.
5. One-Arm Dumbbell Row
- Purpose: Targets the upper back and shoulder muscles to improve strength.
- How to Perform: Place one knee and hand on a bench for support. With the opposite hand, lift a dumbbell toward your torso, keeping your elbow close to your body. Lower slowly. Perform 3 sets of 10 repetitions on each side.
6. Shoulder External Rotation
- Purpose: Enhances the strength of the rotator cuff muscles.
- How to Perform: Hold a resistance band with both hands, elbows at 90 degrees and close to your sides. Rotate your forearms outward, keeping elbows tucked in. Return to the starting position. Perform 3 sets of 10 repetitions.
7. Bent-Over “T” Raise
- Purpose: Strengthens the posterior shoulder muscles.
- How to Perform: Bend at the hips with a flat back, arms hanging down. Raise both arms to the side to form a “T” shape, squeezing the shoulder blades together. Lower slowly. Perform 3 sets of 10 repetitions.
8. Anterior Wall Slide
- Purpose: Improves shoulder mobility and control.
- How to Perform: Stand facing a wall with your forearms against it. Slowly slide your arms upward, maintaining contact with the wall, then return to the starting position. Perform 3 sets of 10 repetitions.
9. Serratus Punch
- Purpose: Activates the serratus anterior muscle to support shoulder movement.
- How to Perform: Lie on your back with a dumbbell in one hand, arm extended toward the ceiling. Without bending your elbow, push the weight upward by protracting your shoulder blade, then return to the starting position. Perform 3 sets of 10 repetitions on each side.
10. Subscapularis Strengthening Exercise
- Purpose: Directly targets the subscapularis muscle to enhance internal rotation strength.
- How to Perform: Stand upright and place the back of your hand against your lower back. Push your hand backward away from your body without rotating your torso. Hold for 5 seconds and return to the starting position. Perform 3 sets of 10 repetitions on each side.
