Setup
- Stand with your feet slightly wider than shoulder-width apart and toes pointed slightly outward.
- Place your fingertips behind your ears with your elbows flared out wide in a 'prisoner' position.
- Engage your core and pull your shoulder blades back to maintain a tall, upright posture.
How to do it
- Inhale as you lower your hips back and down into a squat until your thighs are at least parallel to the floor.
- Exhale and drive through your heels to return to a standing position.
- Immediately shift your weight to the left leg and drive your right knee up toward your right elbow twice in a quick, pulsing 'double crunch' motion.
- Return your right foot to the floor and repeat the sequence, alternating the double knee drive to the left side after the next squat.
Form checklist
- Keep your chest lifted and avoid rounding your lower back during the squat.
- Ensure your knees track in line with your toes and do not cave inward.
- Focus on bringing the knee to the elbow by crunching the side of your torso, rather than pulling your head down.
- Maintain balance on the standing leg by keeping a slight bend in the knee and gripping the floor with your foot.
Pro tips
- Exhale forcefully on each of the two knee drives to deepen the contraction of the obliques.
- Keep your elbows pulled back throughout the entire movement to prevent neck strain and keep the chest open.
- Transition smoothly from the squat to the knee drive to maintain momentum and increase the metabolic demand.
Make it harder
- Add a jump at the top of the squat before performing the double knee drive to increase explosive power.
- Hold a light dumbbell in each hand at shoulder height to add resistance to both the squat and the core rotation.
