Roll Ball Forearm Extensors

Perform the Roll Ball Forearm Extensors to strengthen the muscles in your forearms.

  1. Start by sitting on the floor with your legs extended in front of you.
  2. Place a stability ball between your hands, arms extended in front.
  3. Slowly roll the ball forward, extending your wrists and fingers.
  4. Return to the starting position by rolling the ball back towards you.

How to perform the Roll Ball Forearm Extensors

  1. Set up. Set up in a stable, balanced starting position appropriate for the Roll Ball Forearm Extensors 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 forearms.
  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 forearms 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.
