Setup
- Lie on your side with your legs straight and stacked, then roll slightly back onto the fleshy part of your glute.
- Hold a dumbbell in your top hand with your arm extended straight up toward the ceiling.
- Place your bottom arm on the floor in front of you at a 45-degree angle for balance and light support.
- Engage your core to create a rigid line from your head to your heels.
How to do it
- Exhale as you simultaneously lift your legs and your upper torso off the floor, folding at the waist to bring the dumbbell toward your feet.
- Aim to form a 'V' shape at the top of the movement, balancing on your hip and glute while keeping your arm and legs straight.
- Inhale as you slowly lower your legs and torso back to the starting position with a controlled 2-second eccentric phase.
- Complete all reps on one side before switching the dumbbell to the other hand and repeating.
Form checklist
- Keep your legs squeezed together and knees locked out throughout the entire set.
- Initiate the lift from your obliques rather than pushing off the floor with your bottom arm.
- Ensure the dumbbell stays directly over your shoulder or moves in a slight arc toward the shins.
- Maintain a neutral neck position; do not tuck your chin to your chest during the lift.
Pro tips
- Focus on 'closing the gap' between your lower ribs and your hip bone to maximize the peak contraction of the obliques.
- Pause for a half-second at the top of the movement to emphasize the mind-muscle connection and stability.
Make it harder
- Slow the lowering phase to 4 seconds to increase time under tension.
- Hold a second light dumbbell between your feet to increase the load on the lower abdominals and hip flexors.
