An exercise apparatus comprises a generally rectangular extruded aluminum 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 same metal extrusion material and have the same cross sectional shape. The apparatus includes a movable carriage mounted on the frame for movement along the rail members between the head and foot ends against one or more resistance members connected between the carriage and the foot end of the frame. Each of the rail members includes an outwardly open T shaped longitudinal slot therein for receiving a T shaped anchor bar for a foot support bar assembly. The foot bar assembly includes a replaceable U shaped foot bar having a pair of spaced parallel leg portions. The assembly accommodates various shapes of foot bars. The leg portions are telescopically joined to support members pivotally mounted to a support bracket assembly. Each bracket assembly has an elongated anchor bar member slidably disposed in the slot in the rail member. The bracket assembly also permits the foot bar to be rotated between various positions above the plane of the carriage and rotated to a horizontal position around the foot end for storage. The rail members and head and foot end members are each a metal extrusion comprising a closed middle portion, an outer T shaped slot portion, and an inner C shaped support channel portion. The support rollers are captured in the support channel portion of the rail members and roll on the bottom wall of the extrusion. The guide rollers extend into the support channel portion and roll against vertical rib of the extrusion rail member. The invention further includes laterally adjustable shoulder stops on the carriage and arm support posts that are removable and storable on the frame so that the apparatus may be compactly stored.
