Abstract: An exercising and body-building apparatus of the type in which a carriage having weights suspended therefrom is urged through ascending movement along guide rods during exercising use thereof, wherein a handle attachment of the carriage is vertically adjustable so that the exerciser can more conveniently use the apparatus in either prone or standing position. Also significant is the use of linear bearings in the carriage which obviates binding during the ascending carriage movement, even when the handle is in its most remote adjusted position from the carriage and thus exhibits the greatest tendency to cause a rotative movement in the carriage.
