Setup
- Sit on the floor with your knees bent and feet flat, hip-width apart.
- Lean your torso back to a 45-degree angle until you feel your abdominals engage.
- Extend your arms forward or hold them lightly in front of your chest with palms facing each other.
How to do it
- Rotate your torso to the right and reach your left hand past your right thigh, exhaling as you twist.
- Perform a small, controlled pulse at the end of the reach by moving your hand an extra 2-3 inches further to intensify the oblique contraction.
- Inhale as you return to the center position with control.
- Repeat the sequence on the left side, reaching your right hand past your left thigh, and continue alternating sides.
Form checklist
- Keep your chest lifted and avoid rounding your shoulders or lower back.
- Ensure your hips remain square and both sit-bones stay glued to the floor.
- Initiate the movement from your ribcage rather than just swinging your arms.
- Maintain the 45-degree lean throughout the entire set to keep constant tension on the core.
Pro tips
- Focus on 'wringing out' your midsection like a towel at the peak of the twist to maximize muscle fiber recruitment.
- Keep your neck neutral by following the movement of your hands with your gaze to ensure the thoracic spine is rotating properly.
Make it harder
- Lift your feet 2-3 inches off the ground into a boat pose to increase the stability demand on the lower abs.
- Slow down the pulse phase to a 2-second isometric hold to increase the time under tension for the obliques.
