Setup
- Lie flat on your back with knees bent and feet flat on the floor, hip-width apart.
- Hold a dumbbell with both hands, extending your arms straight overhead so the weight is positioned behind your head.
- Press your lower back firmly into the floor to eliminate any arch in the spine.
How to do it
- Exhale and contract your abdominals to lift your head and shoulder blades off the floor, keeping your arms locked in the overhead position.
- Focus on shortening the distance between your ribs and hips without pulling your lower back off the mat.
- Inhale as you slowly lower back to the starting position, maintaining tension on the abs throughout the descent.
Form checklist
- Keep your arms straight and aligned with your ears; do not swing the weight forward.
- Maintain a neutral neck by keeping a fist-sized space between your chin and chest.
- Ensure your lower back remains glued to the floor throughout the entire range of motion.
- Move with a slow, controlled tempo rather than using momentum.
Pro tips
- Focus on the mind-muscle connection by imagining you are curling your spine one vertebra at a time.
- At the top of the movement, perform a hard forceful exhale to reach peak contraction of the deep core muscles.
Make it harder
- Perform the movement on a decline bench to increase the range of motion and gravitational resistance.
- Lift your legs into a tabletop position with knees at 90 degrees to remove the stability provided by your feet.
