Setup Instructions

Sit tall on short box facing footbar, feet secure under safety strap. Pole held flat across shoulder blades or arms folded across chest.

Execution Instructions

  1. Inhale to grow tall through the crown of the head.
  2. Exhale to rotate the torso from the ribcage to one side, keeping the pelvis stable and the hips square; inhale to return through centre, then exhale to rotate to the other side.

Teaching Cues

Form

"Rotate around spine like a spiral staircase, keeping hips anchored."

Integration

"Maintain broad collarbones and soft shoulders away from ears."

Breath

"Inhale to grow tall, exhale to rotate from the ribcage."

Modifications & Progressions

Arms Folded (Regression)

Fold the arms across the chest to shorten the lever and simplify the rotation.

Pole Extended Reach (Progression)

Hold the pole with arms extended to lengthen the lever and deepen the twist.

Straight Press Only (Injury Modification)

For a disc-sensitive back, keep the trunk square and press the carriage straight out without taking any rotation, or turn only the head and eyes.
