Description The Ab Coaster® PS500 puts you on the fast track to great abs! This machine works exactly the opposite from a traditional ab crunch machine. Rather than working your ab muscles from the top down, the Ab Coaster® PS500 works from the bottom up, helping you target those hard-to-reach lower abs. Just kneel on the comfortable carriage, and pull your knees up. It’s as simple as that! As you lift, the knee carriage glides along the biometrically-designed curved track, engaging your lower abs first, then the middle and upper region, giving you a complete abdominal workout from the bottom-up. The PS500 is the base model Ab Coaster perfect for your HOME GYM. This does NOT fit OLYMPIC weight plates with 2" diameter hole. Must use standard weights with 1" diameter hole.
