An exercise apparatus comprising a generally rectangular extruded aluminum alloy
frame having a head end and a foot end and including a pair of spaced apart parallel
track members wherein the head end, the foot end, and the track or rail members
are each formed from the metal extrusion material. The apparatus includes a movable
carriage made of a rigid frame that moves along the rail members between the head
and foot ends against one or more resistance members connected to the carriage
and the foot end of the frame. Each of the rail members includes a longitudinal
slot therein for receiving a foot support bar assembly. The rail members and head
and foot end members are generally each metal tubular box extrusions and the rail
members telescopically retract. Roller wheels attached to the carriage move along
the top of the rail members and guide wheels move along the inside of the rail
members. The invention further includes shoulder stops on the carriage that can
be adjusted to a horizontal position so that the apparatus may be compactly stored.
