An exercise machine having at least one vertical guide column with centrally located holes mounted on a base, two sleeves with attached bearings, a set of handlebars, and a spring-loaded locking device. One bearing sleeve slides on the vertical guide column, the other slides horizontally on a receiver shaft attached to the sleeve traveling vertically on the guide column. Thus the two bearing sleeves are attached in perpendicular relationship. Bars for securing standard weight-plates are attached to the bearing sleeve which travels on vertical guide column. Handlebars and spring-loaded locking device are attached to the sleeve sliding horizontally on receiver shaft, permitting withdrawal of a spring-loaded locking rod from aforementioned centrally located holes in vertical guide column, as well as horizontal positioning of handlebars during lift and replacement of spring-loaded locking rod into centrally located holes at completion of lift.
