A leg muscle, abdominal muscle, and spinal exercise device adapted for imparting curvature to a lumbar or sacral spine of a user and for manipulating the spine and intervertebral discs with decompression force includes a frame for placement on a floor. The frame has a top surface and a bottom surface, wherein the top surface and bottom surface are in a spaced apart relationship forming a hollow portion there between. At least one inflatable bladder is carried by the top surface of the frame. A body strap attachment passes through the frame in non-fixed relationship and is partially disposed within the hollow portion for encompassing the user's thoracic-sacral spinal region and securing said frame. An elongate stirrup strap member is attachable to the body strap attachment thereby connecting to the user's spinal region. A stirrup is attachable to the stirrup strap member distal end.
