Setup
- Stand facing a wall with a medicine ball held at chest height.
- Place the ball against the wall and position it on the middle (sternal) portion of your pectoral muscle, just off the center of your chest.
- Lean your body weight into the ball to apply firm but manageable pressure.
- Position your feet in a staggered stance for better stability and leverage.
How to do it
- Slowly roll the ball in small, horizontal circles or side-to-side motions across the chest fibers.
- Inhale deeply and exhale as you apply pressure to tight 'trigger points' or knots, maintaining a slow and steady tempo.
- Move the ball from the center of the chest toward the front of the shoulder, pausing on any areas of high tension.
- Perform the movement for 30-60 seconds, then switch to the other side.
Form checklist
- Keep your shoulders relaxed and down, avoiding the urge to shrug.
- Avoid rolling directly onto the sternum (breastbone) or clavicle (collarbone).
- Maintain a neutral spine and avoid arching your lower back as you lean.
- Adjust the intensity by moving your feet further from the wall to increase pressure.
Pro tips
- While pinning a tight spot with the ball, slowly raise and lower your arm on the same side to perform an 'active release' of the muscle.
- Focus on deep diaphragmatic breathing to signal the nervous system to allow the muscle tissue to relax.
Make it harder
- Swap the medicine ball for a smaller, denser tool like a lacrosse ball or trigger point ball for deeper, more localized pressure.
- Increase the angle of your lean to put a higher percentage of your body weight against the ball.
