Technique

How to perform Stability Ball Knee Tucks

  1. Start in a high plank with your hands on the floor beneath the shoulders and your shins or feet supported on the stability ball.
  2. Keep the elbows straight and press through the hands to support your upper body.
  3. Bend the knees toward the chest, rolling the ball inward as you lift the hips and curl the pelvis beneath the torso.
  4. Let the torso angle change as the hips rise rather than trying to freeze the entire spine in the starting position.
  5. Reverse the motion under control, extending the legs and rolling the ball away.
  6. Return to the supported plank without letting the lower back sag or dropping onto the shoulders.
