Setup
- Stand facing a wall and place a medicine ball against the wall at chest height.
- Position the ball just below your collarbone (clavicle) on the target side, near the sternum.
- Lean your body weight forward into the ball to create firm, tolerable pressure.
- Extend the arm of the side being worked slightly out to the side or down by your hip.
How to do it
- Slowly roll the ball horizontally toward the front of your shoulder by moving your body side-to-side.
- Breathe deeply and exhale as you apply pressure to tight spots or 'trigger points'.
- Incorporate small circular motions over particularly dense areas of the upper chest.
- Perform for 30-60 seconds per side, maintaining a slow and controlled tempo.
Form checklist
- Keep your shoulder blade pulled back and down; do not let the shoulder hunch forward.
- Avoid placing the ball directly on the collarbone or the bony part of the shoulder joint.
- Maintain a neutral spine and avoid twisting your torso excessively.
- Ensure the pressure is firm but does not cause sharp pain or numbness.
Pro tips
- To increase the stretch, slowly raise and lower your arm on the treated side in a 'snow angel' motion while pinned against the ball.
- Focus on the area just lateral to the sternum where the upper pec fibers originate for maximum release.
Make it harder
- Increase the pressure by leaning more of your body weight into the wall or using a smaller, firmer ball.
- Pin the ball on a tight spot and rotate your head away from the target side to add a neural stretch component.
