How to do the Decline Crunch
Primary: Core · also works Obliques, Hip Flexors.
The decline crunch is a highly effective abdominal exercise that primarily targets the rectus abdominis muscle. It is performed on a decline bench, which increases the resistance and intensity compared to a standard crunch. By engaging the muscles to lift the upper body against gravity, this exercise helps in building core strength and developing a well-defined midsection. Being an isolation exercise, it emphasizes retracting the core without involving other muscle groups significantly, making it an excellent choice for focusing on abdominal strength.

- 1
Lie down on a decline bench and secure your feet at the top of the bench.
