Setup
- Stand tall with your feet hip-width apart and your core braced.
- Place your hands lightly behind your head with elbows pointed out to the sides.
- Shift your weight onto your left foot, maintaining a soft bend in the knee for stability.
How to do it
- Exhale and lift your right knee toward your chest while rotating your torso to bring your left elbow toward the rising knee.
- Crunch your obliques hard at the top, ensuring the rotation comes from your midsection rather than pulling on your neck.
- Inhale as you controlledly lower your foot back to the floor and return your torso to the neutral starting position.
- Perform the prescribed number of repetitions on one side before switching to the other.
Form checklist
- Keep your chest open and avoid pulling your chin toward your chest.
- Focus on the 'cross-body' connection between the opposite shoulder and knee.
- Maintain a steady, upright posture on the standing leg without leaning too far forward.
- Move with control; avoid using momentum to swing the leg up.
Pro tips
- To increase oblique activation, focus on bringing the shoulder—not just the elbow—across the midline of your body.
- Keep the standing glute squeezed to provide a stable base and improve balance throughout the set.
Make it harder
- Add a 2-second pause at the peak of the contraction to maximize time under tension.
- Hold a light weight or medicine ball at chest height to increase the resistance on the obliques.
