Muscles worked

Primary

  • Pectorals

Secondary

  • Abs
  • Deltoids
  • Serratus anterior

Equipment

  • Medicine ball

Setup

  1. Stand facing a wall and place a medicine ball against the wall at chest height.
  2. Position the ball just below your collarbone (clavicle) on the target side, near the sternum.
  3. Lean your body weight forward into the ball to create firm, tolerable pressure.
  4. Extend the arm of the side being worked slightly out to the side or down by your hip.

How to do it

  1. Slowly roll the ball horizontally toward the front of your shoulder by moving your body side-to-side.
  2. Breathe deeply and exhale as you apply pressure to tight spots or 'trigger points'.
  3. Incorporate small circular motions over particularly dense areas of the upper chest.
  4. 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.
