The Ab Coaster CS3000 is designed to help you exercise your abdominal muscles via a leg lift motion. Unlike the popular ab crunch exercise, which works your ab muscles from the "top down", the Ab Coaster moves in the direction, working your abs from the "bottom up". The motion requires you to lift your knees and legs while contracting your abs. The Ab Coaster features a seat moving along a curved track to aid you in performing the abdominal lift motion. the starting position requires you to kneel on the seat while resting your arms on the arm rests. The exercise requires you to lift the seat using your abdominal muscles, not your upper body. The key to performing the exercise properly is to concentrate on contracting your ab muscles while lifting the seat. Your upper body should be stable and not moving while you exercise.
