Equipment

Setup

  1. Stand tall with your feet hip-width apart and arms extended straight out to your sides at shoulder height.
  2. Step your right foot forward into a wide split stance, keeping your back heel lifted off the ground.
  3. Engage your core and maintain an upright posture with your weight evenly distributed.

How to do it

  1. Inhale as you lower your back knee toward the floor until both legs form 90-degree angles.
  2. Exhale and rotate your torso and arms toward your front leg, keeping your hips facing forward.
  3. Inhale as you rotate back to the center while maintaining the lunge position.
  4. Exhale and push through your front heel to return to the starting standing position, then repeat for the desired reps before switching sides.

Form checklist

  • Keep your front knee stacked directly over your ankle, not tracking past your toes.
  • Ensure the rotation comes from your mid-back and waist, not just your arms.
  • Maintain a vertical spine throughout the movement; avoid leaning forward.
  • Keep your shoulders relaxed and away from your ears during the arm extension.

Pro tips

  • Focus on 'wringing out' your midsection during the twist to maximize oblique activation and spinal decompression.
  • Gently push the hip of your back leg forward during the twist to deepen the stretch in the hip flexors.

Make it harder

  • Hold the lunge and rotation for 3-5 seconds to increase time under tension and balance challenge.
  • Hold a light weight or a water bottle in your hands to add resistance to the rotational phase.
