Setup
- Sit tall on the floor with your legs extended straight in front of you and feet flexed toward your shins.
- Squeeze your inner thighs together and reach your arms out to the sides at shoulder height, forming a 'T' shape.
- Lift through the crown of your head to create a long, neutral spine and engage your deep abdominals.
How to do it
- Inhale deeply to lengthen your spine, then exhale as you rotate your torso to one side using three small, progressive pulses to deepen the twist.
- Inhale as you return to the center with control, maintaining your height and arm position.
- Exhale and repeat the three-pulse rotation to the opposite side.
- Maintain a controlled tempo, ensuring the movement is driven by the waist rather than momentum.
Form checklist
- Keep both sit-bones firmly anchored to the floor; do not let one hip lift as you rotate.
- Ensure your arms stay in a straight line with your shoulders rather than swinging them independently of the torso.
- Keep your heels glued together; if one foot slides forward, your pelvis is rotating instead of your spine.
- Maintain a tall, upright posture throughout the entire set, avoiding any slouching or leaning.
Pro tips
- Imagine your spine is a wet towel being wrung out, focusing on the sensation of narrowing your waist during the twist.
- Focus on growing taller with every rotation to decompress the vertebrae while engaging the obliques.
Make it harder
- Hold a light medicine ball or a resistance band between your hands to add external load to the rotational phase.
- Perform the exercise with your legs in a 'V' position to challenge hip stability and spinal verticality.
