The shoulder bottle shake is a dynamic stability exercise that challenges the rotator cuff and surrounding shoulder muscles through unpredictable resistance. By shaking a partially filled bottle, the shifting weight forces the shoulder to make rapid, small adjustments, improving joint control, coordination, and endurance. It’s often used in rehabilitation and athletic conditioning to enhance resilience during functional and overhead movements.
- Fill a bottle of water 3 quarters full with water.
- Use the water in the bottle to create an oscillating resistance as you move between external rotation and internal rotation.
- Usually completed for at least 30 seconds per set as this is an endurance/control exercise.
- Usually you will start with your elbow by your side and move into higher/more challenging ranges as directed by your physiotherapist.
