Setup
- Lie flat on your back with your knees bent and feet flat on the floor, hip-width apart.
- Place your fingertips lightly behind your ears with your elbows flared out wide.
- Tuck your chin slightly and press your lower back firmly into the floor to engage your deep core.
How to do it
- Exhale as you lift your head and shoulder blades off the floor, rotating your torso to bring one shoulder toward the opposite knee.
- Focus on the contraction in your obliques, ensuring your lower back remains in contact with the mat.
- Inhale as you slowly lower back to the starting position with a controlled 2-second tempo.
- Repeat the movement on the opposite side, alternating sides for each repetition.
Form checklist
- Lead the movement with your shoulder rather than pulling your elbow across your face.
- Keep your elbows wide and avoid pulling on your head or neck with your hands.
- Ensure your hips remain grounded and do not rock side-to-side during the rotation.
- Maintain a small gap between your chin and chest throughout the entire set.
Pro tips
- Visualize bringing your ribcage toward the opposite hip bone to maximize oblique fiber recruitment.
- Pause for a one-second peak contraction at the top of each rep to intensify the burn.
Make it harder
- Perform the exercise with your legs in a 'tabletop' position (hips and knees at 90 degrees) to increase tension on the lower abs.
- Slow down the eccentric (lowering) phase to 3-4 seconds to increase time under tension.
