Roll Ball Deltoid Posterior

DeltoidsRollerIntermediate

Perform the Roll Ball Deltoid Posterior to target the posterior deltoid muscles effectively.

  1. Start by sitting on the floor with your legs extended in front of you.
  2. Hold a stability ball with both hands, arms extended in front.
  3. Lean back slightly, engaging your core, and roll the ball towards your body.
  4. As the ball approaches, pull your elbows back, squeezing your shoulder blades together.
  5. Return to the starting position and repeat for the desired number of repetitions.

How to perform the Roll Ball Deltoid Posterior

  1. Set up. Set up in a stable, balanced starting position appropriate for the Roll Ball Deltoid Posterior 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 deltoids.
  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 deltoids 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.
