How to Perform

Adjust the suspension straps to mid-calf length. Kneel facing away from the anchor point, place your feet into the foot cradles, and position your forearms on the floor with elbows directly under your shoulders.

  1. Brace your core and squeeze your glutes.
  2. Lift your knees off the floor to extend your legs fully.
  3. Align your body in a straight line from head to heels.
  4. Drive your forearms into the floor to keep shoulders active.
  5. Hold the position without letting hips sag or pike.
  6. Maintain steady breathing while keeping tension.
  7. Lower knees gently to the floor to finish.
