Weighted Decline Sit-Up

Muscles worked

Setup

1. Set the decline bench to a 30-45 degree angle and secure your ankles firmly under the foot pads.
2. Sit upright and hold a weight plate with both hands, extending your arms straight up toward the ceiling.
3. Engage your core and pull your ribs down to set your starting position with a neutral spine.

How to do it

1. Inhale and slowly lower your torso toward the bench over a 2-3 second count, keeping your arms locked and the plate pointed directly at the ceiling.
2. Stop the descent just before your shoulder blades touch the bench to maintain constant tension on the abdominals.
3. Exhale as you use your abdominals to curl your torso back to the upright starting position.
4. Keep the weight plate aligned vertically over your center of gravity throughout the entire range of motion.

Form checklist

• Keep your arms fully extended and the plate reaching for the ceiling at all times.
• Avoid arching your lower back excessively at the bottom of the movement.
• Keep your chin tucked slightly toward your chest to avoid neck strain.
• Ensure the movement is driven by your abs rather than pulling with your hip flexors.

Pro tips

• Focus on 'curling' your spine down one vertebra at a time to maximize rectus abdominis recruitment and minimize hip flexor dominance.
• Maintain a slight posterior pelvic tilt throughout the movement to keep the tension off your lumbar spine.

Make it harder

• Increase the angle of the decline bench to create a steeper path against gravity.
• Pause for 2 seconds at the bottom of the rep (the point of maximum tension) before ascending.
