The exerciser's back is maintained in a forwardly curved position with the knees bent and the feet resting on the floor while the exerciser rocks forwardly to stress the abdominal muscles. The device includes a curved support surface on which the exerciser is supported with the back forwardly curved, and includes base structure which allows the support surface to rock back and forth with the exerciser whereby the exerciser's back stays forwardly curved.
