Setup
- Lie on your side with your legs straight and stacked, angled roughly 30 degrees forward from your hips to create a stable base.
- Extend your bottom arm straight out on the floor in front of you at a 45-degree angle for balance.
- Place your top hand lightly behind your head or reach it toward your feet to prepare for the contraction.
How to do it
- Exhale as you simultaneously lift your legs and your upper torso off the floor, pivoting on your bottom hip and glute.
- Contract your obliques to bring your torso and legs together into a 'V' shape, reaching your top hand toward your shins.
- Inhale as you slowly lower your legs and torso back to the floor with a controlled 2-second eccentric phase.
- Complete the full set on one side before switching to the opposite side.
Form checklist
- Keep your legs squeezed together and knees straight throughout the entire rep.
- Avoid pushing off the floor with your bottom arm; use it only for light stabilization.
- Focus on bringing your ribcage toward your hip bone rather than just lifting your legs.
- Maintain a neutral neck and avoid pulling on your head with your top hand.
Pro tips
- Pause for a one-second peak contraction at the top of the movement to fully exhaust the oblique fibers.
- Visualize 'folding' your body at the waist to ensure the movement is driven by the core rather than momentum from the hip flexors.
Make it harder
- Hold a light dumbbell or medicine ball between your feet to increase the lever's resistance.
- Perform the movement with your bottom arm lifted off the floor to remove the balance assist and force the core to stabilize the entire body.
