Abstract: An exercise device focusing on core strengthening and development of abdominal and gluteal muscle groups provides a curved inner track which provides a rolling seat and a flat outer track providing a rolling leg support over which the legs of a user engage, positioning the body in a recumbent position, with contraction and extension of the abdomen of the user compelling the rolling seat and rolling leg support using a pelvic thrusting motion to strengthen and exercise lower back, abdominal, gluteal, quadriceps and hamstring muscles and to improve and refine a shape and condition of the muscle groups.
