Abstract: An exercising apparatus which can be used as a rowing machine or for performing other types of exercises not possible with a rowing machine, by having the pivotally mounted ends of the lever members of the rowing machine-type exerciser selectively movable between a position on the base frame and a position on a vertically extending column member adjacent the foremost end of the base frame.The base frame contains a longitudinally extending track, with a seat mounted on the track for longitudinal movement relative thereto when the lever arms are in the rowing-machine position.An elongate body support member is provided for mounting on the frame in longitudinal alignment with the seat when the levers are pivotally mounted on the column member, to provide a surface upon which the user can stand or lie while actuating the lever members.
