Setup
- Sit on the floor with your knees bent and feet flat, then lean your torso back at a 45-degree angle to engage your core.
- Lift your feet off the floor and extend your arms out to the sides, balancing on your sit bones in a V-position.
- Keep your spine neutral and your chest lifted to maintain a strong, upright posture.
How to do it
- Exhale as you rotate your torso and reach your right hand toward your left toes while simultaneously extending your left leg straight out.
- Inhale as you return to the starting V-sit position, pulling your knee back in and centering your torso.
- Repeat the movement on the opposite side, reaching your left hand toward your right toes while extending your right leg.
- Maintain a slow, controlled tempo, ensuring your feet remain hovering off the floor for the entire set.
Form checklist
- Keep your chest up and avoid rounding your lower back as you reach.
- Ensure the rotation occurs at the waist and ribcage, not just the shoulder joint.
- Keep your core braced and avoid letting your feet touch the ground between repetitions.
- Maintain a neutral neck position by following the movement of your torso with your gaze.
Pro tips
- Focus on the 'mind-muscle connection' by imagining you are wringing out your midsection like a towel at the peak of the rotation.
- Pause for a split second when your hand reaches your toe to maximize the peak contraction of the obliques.
Make it harder
- Perform the exercise while sitting on the edge of a flat bench to increase the range of motion and the stability requirement.
- Hold a light medicine ball or dumbbell with both hands to add resistance to the rotational phase.
