How to do Side Lying Internal Rotation

01
Setup
Lie on your side with your top arm bent to 90 degrees at the elbow, forearm resting across your abdomen or chest. Ensure your elbow is tucked close to your side.
02
Setup
Your palm should be facing down or towards your torso, and your upper arm should remain still against your side throughout the exercise.
03
Slowly lower your forearm towards the floor by internally rotating your shoulder, keeping your elbow fixed to your side.
04
Continue the rotation until your forearm is parallel to the floor or as far as comfortable without lifting your elbow from your side.
05
Gently reverse the movement, bringing your forearm back to the starting position with control, focusing on the internal rotation muscles.

Tips

Keep your elbow firmly glued to your side throughout the entire movement to isolate the rotator cuff muscles effectively.
Perform the rotation slowly and with control, avoiding any jerky movements or using momentum to complete the range of motion.
Focus on initiating the movement from your shoulder joint, feeling the internal rotation muscles (subscapularis) engage.

Common mistakes

Lifting the elbow off your side shifts the tension away from the rotator cuff; fix this by actively pressing your elbow into your torso.
Using momentum to swing the arm down reduces muscle activation; fix this by performing the movement slowly and deliberately in both directions.
Over-rotating past your comfortable range can strain the shoulder joint; fix this by stopping at the first sign of tension or discomfort.
