Movable kneeling pad assembly for an abdominal exercise device

Abstract

A movable kneeling pad assembly for an abdominal exercise device has a main pad and a wheel seat. The main pad has at least one kneeling recess formed in an upper surface of the main pad. The wheel seat is mounted on a lower surface of the main pad and has multiple wheels protruding from the lower surface of the main pad. The kneeling pad assembly provides a comfortable support for a user's knees. As the kneeling pad assembly is movable by rotation of the wheels, the user has to put forth high abdominal strength in order to simultaneously perform movements of his upper body and his lower body. Therefore, abdominal muscles of the user can be trained effectively and efficiently, and exercise intensity when using the abdominal exercise device is high enough for professional workout exercisers.
