How to perform this stretch?
- Start by standing with the ball over the supraspinatus muscle (see diagrams and video if unsure)
- Bring the arm so that the elbow is in line with the shoulder
- Slowly rotate the arm upwards whilst maintaining the line of the elbow
- If you find a painful area stay on that area until the pain lessens before moving the ball.
Variation:
Try doing this with the hips lifted in a ‘glute bridge’ position
