Setup
- Secure your feet firmly under the rollers of a decline bench set to a 30-45 degree angle.
- Sit on the bench and hold a single dumbbell with both hands at chest height.
- Slowly lean back until your torso is parallel to the floor, then extend the dumbbell straight up toward the ceiling.
- Ensure your arms are fully locked out and the weight is stacked directly over your shoulders.
How to do it
- Exhale and contract your abs to sit up, keeping the dumbbell 'punched' toward the ceiling so it remains vertically aligned over your shoulders.
- Continue the movement until your torso is upright and the dumbbell is directly overhead.
- Inhale as you slowly lower your torso back to the starting position with a controlled 3-second eccentric phase.
- Maintain the vertical orientation of the dumbbell throughout the entire range of motion, never letting it drift forward.
Form checklist
- Keep the dumbbell stacked vertically over the shoulders at all times.
- Avoid swinging the weight or using momentum to pull yourself up.
- Keep your chin slightly tucked to maintain a neutral cervical spine.
- Ensure your lower back makes contact with the bench first during the descent.
Pro tips
- Focus on 'peeling' your spine off the bench one vertebra at a time to maximize abdominal recruitment and minimize hip flexor dominance.
- Actively push the dumbbell toward the ceiling at the top of the rep to fully engage the serratus anterior and deltoids.
Make it harder
- Increase the decline angle of the bench to further increase the lever arm and resistance.
- Hold the dumbbell with one hand to create an offset load, significantly increasing the demand on the obliques for rotational stability.
