Exercise guide

Roll Ball Infraspinatus

  • Beginner
  • Isolation
  • Timed hold
  • Back
  • Shoulders

This soft tissue release technique targets the infraspinatus to improve shoulder mobility, reduce tightness, and enhance rotator cuff function. It is highly effective for relieving shoulder impingement symptoms and preparing the joint for overhead or pressing movements.

Muscles worked

Primary

  • Rotator cuff

Secondary

  • Lats
  • Rhomboids

Equipment

  • Medicine ball

Setup

  1. Stand with your back slightly angled toward a wall and place the medicine ball between the wall and the back of your shoulder blade.
  2. Position the ball specifically on the infraspinatus, which is the fleshy area just below the bony ridge of the scapula.
  3. Lean your body weight into the ball to apply firm, tolerable pressure against the muscle.

How to do it

  1. Move your body slowly in small circular or side-to-side motions to massage the muscle tissue and identify tight 'trigger points'.
  2. Once a tender spot is found, hold the pressure and slowly rotate your forearm up and down (internal and external rotation) to pin and stretch the muscle.
  3. Maintain steady, deep diaphragmatic breathing, exhaling as you sink deeper into the pressure points.
  4. Spend 30-60 seconds on one side before switching to the other shoulder.

Form checklist

  • Keep the shoulder of the working side relaxed and down, away from your ear.
  • Avoid rolling directly onto the bony spine of the scapula; stay on the muscle belly.
  • Maintain a neutral spine and avoid arching your lower back to create pressure.
  • Keep your feet staggered or slightly away from the wall for better balance and leverage.

Pro tips

  • To increase the stretch, reach your arm across your chest while the ball is pinned to pull the shoulder blade forward and expose more of the muscle.
  • Focus on 'melting' into the ball during the exhale rather than tensing up against the discomfort to allow the fascia to release.

Make it harder

  • Increase the pressure by stepping your feet further away from the wall, leaning more body weight into the medicine ball.
  • Perform full overhead reaching motions with the arm while keeping the ball pinned to the infraspinatus to challenge the muscle through its full range.
