Setup
- Stand with your feet shoulder-width apart and your knees slightly bent.
- Place your fingertips lightly behind your ears with your elbows flared out wide to the sides.
- Engage your core by drawing your navel toward your spine to establish a stable base.
How to do it
- Drive your right knee up toward your chest while simultaneously rotating your torso to bring your left elbow toward the rising knee.
- Exhale sharply at the peak of the movement, focusing on the contraction in your obliques.
- Return to the starting position and immediately repeat the movement on the opposite side in a fluid, alternating 'cycling' motion.
- Maintain a fast, rhythmic tempo, staying light on the balls of your feet throughout the set.
Form checklist
- Keep your chest upright and avoid pulling your head forward with your hands.
- Ensure the rotation comes from your midsection rather than just moving your arms.
- Drive the knee as high as possible to fully engage the lower abdominals and hip flexors.
- Maintain a slight bend in the standing leg to absorb impact and improve balance.
Pro tips
- Focus on the 'rib-to-hip' connection; imagine wringing out your torso like a towel at the top of every rep.
- Keep your elbows pinned back to force your obliques to do the work of rotating the ribcage.
Make it harder
- Add a small hop on the standing leg as you crunch to turn the movement into a plyometric exercise.
- Increase the speed of the transitions while maintaining a full range of motion for maximum metabolic demand.
