Decline Crunch

What you'll gain

• Increases abdominal loading over a floor crunch without adding any external weight.

• Keeps the range short and the lower back supported, which suits high rep finisher work.

• Progresses by bench angle alone, so one station covers several difficulty levels.

Step-by-Step Instructions

1. 1

   Set a decline bench to a moderate angle and hook your feet under the roller pads.

2. 2

   Lie back with your knees bent and your lower back resting on the bench.

3. 3

   Cross your arms over your chest or rest your fingertips beside your ears without pulling on the neck.

4. 4

   Exhale and curl your shoulder blades off the bench by shortening the abdominals.

5. 5

   Stop once the upper back has left the pad, keeping the lower back in contact.

6. 6

   Inhale and lower slowly to the start without resting at the bottom.

Common Mistakes

• Pulling on the head with the hands, which strains the neck and hides how little the abdominals moved.

• Curling all the way up into a sit-up, which hands the work to the hip flexors.

• Setting the decline too steep too soon, which usually turns into a swinging half rep.

• Dropping back to the bench between reps, which discards the eccentric and the tension with it.

About This Exercise

The decline crunch is a crunch performed head-down on an angled bench with the feet secured. Only the shoulder blades leave the pad; the lower back stays in contact throughout, which keeps the movement in trunk flexion rather than hip flexion. Declining the bench increases the resistance gravity applies at the start of the range, so the abdominals work harder than they would on the floor for the same rep count. Steeper angles make it harder, which gives a simple progression without adding external load. In a product catalog the decline crunch sits alongside the decline sit-up as the shorter-range option of the pair. It fits abdominal finishers in app programs, bench-equipment collections, and comparison content explaining the difference between a crunch and a sit-up.
