Roll Ball Diaphragm

The Roll Ball Diaphragm exercise focuses on enhancing your diaphragm strength and breath control.

  1. Begin by sitting comfortably with your feet flat on the ground.
  2. Hold a stability ball at chest level with both hands.
  3. Inhale deeply, expanding your diaphragm.
  4. Exhale slowly while pressing the ball away from your chest.
  5. Return to the starting position and repeat.

How to perform the Roll Ball Diaphragm

  1. Set up. Set up in a stable, balanced starting position appropriate for the Roll Ball Diaphragm using your roller.
  2. Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your abdominals.
  3. Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your abdominals rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
  • Letting your spine round or hyperextend instead of staying neutral.
