Shoulder Medial Rotation
Positioning
Stand Up Straight: Begin by standing up straight with your feet shoulder-width apart. Ensure your posture is tall, with your head aligned over your shoulders.
Arm Position: Bend your elbow at a 90-degree angle. Position your forearm parallel to the floor, keeping your upper arm close to your body.
Movement Instructions
Starting Position: With your palm facing up, hold your forearm at a right angle. This is your starting position.
Rotation: Slowly rotate your forearm inward (towards your body), keeping your elbow stationary. Your palm should turn to face your belly as you rotate.
Return to Start: After reaching the inward rotation, slowly reverse the movement to return your forearm to the starting position, ensuring controlled motion both ways.
Repetitions: Aim for 10-15 repetitions on one side before switching to the other arm.
Tips
Maintain a steady breathing pattern throughout the exercise.
Focus on the range of motion and control rather than speed.
If using a resistance band, anchor it at waist level to provide consistent resistance during the move.
Caution
Avoid any jerky movements to prevent strain.
If you experience pain, stop the exercise immediately and consult a fitness professional or physician.
