An abdominal massaging device includes a support and a first plate rotatably mounted on the support. At least one projection extends from and is rotatably mounted upon the first plate. In this way, the projection is effective to rotate with respect to the surface of the plate. In an alternative embodiment a plurality of second plates are disposed on the first plate and projections are disposed on the second plates. The supports for the device further include concave portions for receiving a user's pelvis and rib cage.
