The cable seated crunch is a loaded trunk flexion exercise performed on a bench or seat facing away from a high pulley, pulling a rope down as the spine curls forward. The cable provides constant, adjustable resistance, which makes it one of the best ways to progressively overload the rectus abdominis like any other muscle. It is used by lifters who want ab strength and thickness rather than just endurance.
