Setup

  1. Stand tall with your feet hip-width apart and your core engaged.
  2. Extend your arms straight out in front of your chest, pressing your palms together or making fists.
  3. Maintain a neutral spine with your shoulders pulled back and down.

How to do it

  1. Step forward into a lunge, lowering your back knee toward the floor until both legs form 90-degree angles.
  2. While holding the lunge position, exhale and rotate your torso and arms over your lead leg as far as your mobility allows.
  3. Inhale as you rotate your torso back to the center with control.
  4. Drive through the heel of your front foot to return to the standing starting position.

Form checklist

  • Keep your front knee aligned over your ankle, preventing it from caving inward during the rotation.
  • Ensure the rotation comes from your mid-back (thoracic spine) rather than just swinging your arms.
  • Maintain an upright torso; do not lean forward or sideways as you twist.
  • Keep your hips squared forward even as your upper body rotates.

Pro tips

  • To maximize oblique engagement, imagine 'wringing out' your midsection like a towel at the peak of the rotation.
  • Focus your gaze on your hands throughout the movement to help maintain balance and ensure full cervical rotation.

Make it harder

  • Perform the movement as a continuous walking lunge to increase the demand on your stability and coordination.
  • Add a 2-second isometric hold at the deepest part of the rotation to increase time under tension.
