Decline Crunch

A crunch performed on a decline bench, increasing difficulty through gravitational resistance and allowing extended range of motion.
Instructions
- Secure your legs at the end of the decline bench and lie back on it.
- Place your hands lightly on either side of your head, keeping your elbows in. Do not lock your fingers behind your head.
- Push the small of your back down into the bench to isolate your abdominal muscles.
- Roll your shoulders off the bench by contracting your abdominals and exhaling.
- Your shoulders should come up off the bench only about four inches, with your lower back remaining on the bench.
- Contract your abdominals hard at the top and hold for a second.
- Slowly come down to the starting position as you inhale, taking at least 2-3 seconds for the descent.
- Repeat for the prescribed number of repetitions.
Tips
- Focus on slow, controlled movement; avoid using momentum.
- The decline angle increases the challenge compared to floor crunches.
- Keep tension on the abdominals throughout by not fully relaxing at the bottom.
- If this is too difficult, use an incline bench or perform on a flat surface first.
