Abstract: An exercise device has a first frame, where the first frame is generally rectangular and has a head end and a first juncture end. A fixed body support is fixed on the first frame and is configured to support a torso of an exercise participant. A second frame has a second juncture end, a foot end and a pair of rail members extending along opposite sides of the second frame, respectively, between the second juncture end and the foot end. A carriage is mounted on the second frame for movement along the rail members along locations confined between the second juncture end and the foot end. Wheels mounted to the carriage facilitate movement of the carriage along the rail members, among other things, prevent the carriage from tilting upwardly as it is driven toward the foot end.
