The machine crunch uses a seated selectorized ab machine that loads spinal flexion through a fixed path and chest or shoulder pad. It is beginner friendly and easy to progress, letting you add weight to the rectus abdominis without balance or setup demands. Drive the contraction with the abs rather than the arms or hips, curling the torso forward and controlling the return.
