The BEST Rotator Cuff Strengthening Exercises (Science-Based)

Summary by Krater

A physical therapist breaks down the anatomy of the rotator cuff and evaluates scientific studies to determine which exercises are most effective for activating the infraspinatus, supraspinatus, and deltoid muscles, recommending specific parameters and alternative movements for shoulder rehabilitation and strength training.

Answers: What are the best exercises for rotator cuff rehabilitation and muscle activation?

• rotator cuff anatomy and muscle functions
• electromyographic analysis of shoulder exercises
• best exercises for infraspinatus and teres minor activation
• supraspinatus activation across different exercise positions
• deltoid muscle activation during rotator cuff exercises
• moment arms of muscles spanning the glenohumeral joint
• recommended parameters for shoulder exercises
• strength training movements targeting shoulders and rotator cuff

Exercises

• external rotation variation · resistance band
• standing arm raise · dumbbells
• prone arm raise · bench, dumbbells
• sidelying external rotation · bench, dumbbell
• standing dumbbell external rotation · dumbbells
• standing banded external rotation · resistance band
• prone Y · bench, dumbbells
• standing banded external rotation · resistance band
• empty can · dumbbells
• full can · dumbbells
• sidelying external rotation · bench, dumbbell
• lateral raise · dumbbells
• overhead press · dumbbells
• overhead press · barbell
• pulling exercise · dumbbell
• pull-up · pull-up bar

What it concludes

• Sidelying external rotation produces the greatest amount of EMG activity for the infraspinatus and teres minor.
• Standing dumbbell external rotation creates no tension on the rotator cuff due to the pull of gravity and only stresses the biceps.
• Band external rotation produces the least posterior deltoid activation among standing banded, prone Y, and prone external rotation.
• Exercises moving the shoulder through abduction typically show the most supraspinatus activation.
• Lateral raise and sidelying external rotation are more favorable for activating the rotator cuff over deltoid muscles when rotator cuff preference is desired.
• Performing 2 to 4 sets of 10 to 20 repetitions close to fatigue 2 to 3 times a week is a general recommendation for shoulder tissue capacity.
