Setup
- Sit tall on the edge of a stable chair with your feet flat on the floor, hip-width apart.
- Engage your core and lengthen your spine, pulling your navel toward your backbone.
- Place your hands lightly behind your head with elbows wide, or cross your arms over your chest.
- Ensure your weight is evenly distributed across both sit-bones.
How to do it
- Exhale as you slowly rotate your torso to one side, leading the movement with your ribs and obliques.
- Inhale as you return to the center starting position in a slow, controlled manner.
- Repeat the rotation to the opposite side, keeping your hips and knees facing directly forward.
- Maintain a steady 2-1-2 tempo: two seconds to rotate, a one-second pause at the peak, and two seconds to return.
Form checklist
- Keep your hips glued to the chair; do not let your knees shift forward or back.
- Maintain a perfectly upright posture; avoid slouching or leaning into the backrest.
- Rotate from the waist and mid-back rather than just pulling with your neck or elbows.
- Keep your feet firmly planted on the ground to provide a stable base.
Pro tips
- Imagine wringing out a wet towel with your midsection to maximize the mind-muscle connection with your obliques.
- Focus on 'growing taller' as you rotate to prevent spinal compression and increase range of motion.
Make it harder
- Hold a light weight, such as a dumbbell or water bottle, against your chest to add rotational resistance.
- Lift the knee of the side you are rotating toward slightly off the floor to further engage the lower abdominals and challenge balance.
