Setup
- Sit on the floor with your knees bent and feet flat, holding a kettlebell by the horns (sides of the handle) at chest height.
- Lean your torso back to approximately a 45-degree angle until you feel your abs engage, keeping your spine neutral and chest proud.
- Lift your feet 2-3 inches off the floor to create a 'V' shape with your body, balancing on your sit bones.
- Pull your shoulder blades back and down to stabilize your upper back.
How to do it
- Exhale and rotate your torso to the right, moving the kettlebell toward the floor beside your right hip.
- Inhale as you rotate back to the center position with control.
- Exhale and rotate to the left side, ensuring the movement comes from your ribs rather than just your arms.
- Maintain a controlled, rhythmic tempo, alternating sides for the desired number of repetitions.
Form checklist
- Keep your chest lifted and avoid rounding your lower back or shoulders.
- Follow the kettlebell with your eyes and head to ensure full thoracic rotation.
- Keep your knees as still as possible; avoid letting them swing side-to-side as you rotate.
- Ensure the kettlebell stays close to your body to protect your lower back.
Pro tips
- Focus on 'wringing out' your midsection like a towel at the end of each rotation to maximize oblique recruitment.
- Maintain a slight pelvic tilt (tucking your tailbone) to keep the tension on your abs and off your hip flexors.
Make it harder
- Straighten your legs further away from your body to increase the lever length and core demand.
- Slow down the tempo to a 3-second eccentric (lowering) phase on each rotation to increase time under tension.
