An exercise device for use in exercising and strengthening abdominal and lower back muscles. The device is easily utilized, may be readily disassembled, and is easily portable. The device utilizes individual upright resilient bars of varying degrees of resistance which may be interchangeably affixed to a seat portion of the device. The upper portion of the resilient bar feature, which may be bowed in one direction, has an attached padded upper body support on one side and a harness element on the other. The user may sit on the seat element and exert back-ward pressure against the upper back support to exercise lumber (extensor) paraspinal muscles of the lower back, or the user may sit on the seat element gripping a handlebar assembly affixed to the upper end of the resilient bar and bend forwardly exerting pressure away from the bar to exercise the abdominal muscles. A padded lower back support is provided to assist in properly positioning the user on the device.
