Abstract

Abstract A portable exercising device of simplified design and construction which enables a user to perform a number of different types of exercises. An upright frame or scaffold is provided. A cage or frame for supporting weights is positionable between uprights at the sides of the frame or scaffold. A system of pulleys and lines is provided with detachable hand grips or a bar at the ends of the lines so that a user in various positions holding the hand grips or bar can pull on the lines to raise and lower the cage holding the weights. The user may work between the uprights at the sides of the frame to perform uplifting exercises using barbells and the like. The system of pulleys includes pulley blocks and pulleys at the lower part of the frame and pulley blocks and pulleys at the upper part, the lower ones being swivel mounted and the upper ones being hinged. Alternatively, the lines can pass or not pass over the lower pulleys, the device thereby accommodating many different manners or modes of utilization.
