The POWER CRUNCH 500 out-performed all major abdominal floor exercises (up to 51% greater involvement in the upper region of the rectus abdominis and 44% greater in the lower region).
Only the Power Crunch 500 uses patented dual pivot technology to precision target both upper and lower Abdominal crunch movements simultaneously.
Only the Power Crunch 500 offers left and right oblique isolation--simple adjustment allows easy isolation of side to side internal & external oblique muscles.
Laboratory testing at University of Houston's Department of Human Performance confirms the Power Crunch 500 creates 52% more muscle activation by the abdominals because you're directly hitting the upper and lower abs in one efficient motion.
Resistance can be increased by adding standard weights to the built-in peg.
