Setup
- Sit upright on the edge of a chair or flat bench with your feet planted firmly on the floor, hip-width apart.
- Maintain a neutral spine with your shoulders pulled back and your chest lifted.
- Place your hands lightly behind your head with elbows flared, or cross your arms over your chest.
How to do it
- Exhale and slowly rotate your torso to one side as far as your range of motion allows, keeping your hips glued to the seat.
- Pause for one second at the end of the rotation to maximize the contraction in your obliques.
- Inhale as you return to the center position with a slow, controlled tempo.
- Repeat the movement on the opposite side, alternating sides for the duration of the set.
Form checklist
- Keep your hips and knees facing forward at all times; do not let your lower body shift.
- Maintain a tall, vertical spine—avoid slouching or leaning forward during the twist.
- Initiate the movement from your waist and ribs rather than just pulling with your shoulders.
- Keep your chin aligned with your sternum so your neck follows the natural curve of the rotation.
Pro tips
- Imagine your spine is a central axis and you are rotating around it like a screw to ensure pure rotational movement.
- Focus on 'pulling' with the oblique on the side you are turning toward while 'pushing' with the opposite side for maximum muscle fiber recruitment.
Make it harder
- Hold a light medicine ball or dumbbell against your chest to add resistance to the rotation.
- Lift your feet two inches off the floor to engage the lower abdominals and challenge your balance while twisting.
