Abstract: An exercise device is providing for suspending the body above a support surface while a person performs exercises designed to stretch and strengthen the full range of back extensor, abdominal and gluteus maximus muscles. The device includes a pelvic brace which cooperates with a rotatable leg restraining member to position the body, in a cantilevered fashion, above the support surface nearly horizontally and face down preparatory to exercising the back extensor and abdominal muscles. Alternatively, the device can be mounted differently to strengthen and tone the gluteus maximus muscles. Utilizing gravity traction, the exercise device tends to decompress the spinal column while the exercises are being performed.
