Setup
- Stand with your feet shoulder-width apart and a slight bend in your knees.
- Interlace your fingers or clasp your hands together in front of your chest with elbows flared out.
- Engage your core and maintain an upright posture with your chest lifted and shoulders back.
How to do it
- Drive your right knee up toward your chest while simultaneously rotating your torso to bring your hands toward the outside of the right hip.
- Exhale sharply as you reach the peak of the rotation and knee drive, squeezing your obliques.
- Inhale as you return your foot to the floor and bring your hands back to the center starting position.
- Repeat the movement on the opposite side, alternating legs in a fluid, rhythmic tempo.
Form checklist
- Rotate from the waist and ribcage rather than just swinging your arms.
- Keep your standing leg slightly bent to maintain balance and protect the knee joint.
- Maintain a tall spine throughout the movement; do not crunch forward or round your shoulders.
- Pivot slightly on the ball of the stationary foot to allow for a full, safe range of motion.
Pro tips
- Focus on 'wringing out' your midsection like a towel at the top of the movement to maximize oblique engagement.
- Keep your gaze following your hands to ensure your neck and upper back rotate in alignment with your torso.
- Maintain constant tension in your shoulders by keeping your arms active and away from your chest.
Make it harder
- Increase the speed of the movement to a 'running' pace to turn it into a high-intensity metabolic exercise.
- Hold a light weight or medicine ball to increase the rotational resistance and shoulder demand.
