Setup
- Stand on a sturdy step or plyo box with your feet hip-width apart and toes near the edge.
- Hold a dumbbell with both hands using an overhand grip, letting it hang naturally at arm's length.
- Stand tall with your shoulders back and a very slight, soft bend in your knees.
How to do it
- Begin the movement by tucking your chin to your chest and slowly rounding your upper back.
- Exhale as you continue to 'peel' your spine down one vertebra at a time, keeping the dumbbell close to your legs.
- Lower the weight as far as your flexibility allows, ideally reaching below the level of your feet.
- Inhale as you slowly reverse the movement, rolling back up by stacking your vertebrae from the bottom up until you return to a neutral standing position.
Form checklist
- Move slowly and segmentally; do not rush the descent or ascent.
- Keep your legs straight but avoid locking out the knees aggressively.
- Keep the weight centered and close to your shins throughout the movement.
- Stop immediately if you feel any sharp pain or excessive pressure in the lower back.
Pro tips
- Visualize your spine as a bicycle chain being laid down and picked up link by link.
- Focus on the 'active' stretch in the hamstrings at the bottom of the movement to maximize eccentric loading.
- Start with a very light weight to master the articulation before progressing to heavier loads.
Make it harder
- Increase the weight of the dumbbell while maintaining a slow 4-6 second tempo.
- Use a higher platform to allow for a deeper range of motion if your flexibility permits.
