Setup
- Sit on the floor with your knees bent and feet flat, holding a medicine ball with both hands at chest level.
- Lean your torso back at a 45-degree angle, creating a 'V' shape with your thighs and upper body.
- Lift your feet 2-3 inches off the floor to engage the lower abdominals and find your balance on your sit bones.
- Draw your navel toward your spine and pull your shoulder blades back to maintain a proud chest.
How to do it
- Exhale and rotate your entire torso to the right, bringing the medicine ball toward the floor beside your right hip.
- Inhale as you return to the center position with control, keeping the ball at chest height.
- Exhale and rotate to the left side, ensuring the movement comes from your waist rather than just your arms.
- Continue alternating sides in a fluid, rhythmic motion while maintaining a stable lower body.
Form checklist
- Keep your spine neutral and avoid rounding your lower back into a 'C' curve.
- Ensure your knees remain relatively still; do not let them sway in the opposite direction of your twist.
- Follow the medicine ball with your eyes to ensure your neck and thoracic spine rotate together.
- Keep the ball close to your torso to maintain better control over the resistance.
Pro tips
- Focus on 'wringing out' your midsection at the end of each rotation to maximize the peak contraction of the obliques.
- Squeeze the medicine ball slightly with both hands to create irradiation, which increases total core tension and stability.
Make it harder
- Straighten your legs fully to increase the lever length, significantly raising the demand on the hip flexors and lower abs.
- Perform the movement with a 'pause and hold' for 2 seconds at the furthest point of each rotation.
