Wonder Core's revolutionary 6-in-1 ab sculpting system. With the Wonder Core’s revolutionary dual-resistance design, your muscles are firing throughout the entire range of motion, on the way down as well as on the way up! You’re doing a reverse crunch against resistance as you lie back and a regular crunch as you come up. And unlike ab machines in the gym that work through a limited range of motion, Wonder Core can go beyond 180 degrees with an extended range of motion to target your core like never before! With its adjustable resistance – anyone can do it!
