Prime Movers

  • Scapular retractors, posterior deltoid, rotator cuff

Physio Tips

  • Keep your neck straight, chin tucked and chest up to strengthen neck stabilizers. Pushing your tongue against the roof of your mouth and gripping an imaginary grapefruit between your chin and your chest help to engage the deep neck flexors.
  • The ball should remain motionless throughout this exercise.
  • Letting your chin poke or talking to your gym buddy while you do this exercise leaves your neck at risk for injury.


  • Add 1-2 kg dumbbells.
  • Add some air to your stability ball to make it less stable
  • Try lifting one of your feet off the ground while you perform this exercise to challenge balance.
  • Try balancing your feet on an upsidedown Bosu as you perform the exercise

This ball exercise biases infraspinatus and teres minor, muscles that are very active in controlling your shoulder during the end phases of the throwing motion. This is therefore great for throwers and baseball players.
