ABSTRACT:
An exercise apparatus includes an upright column, with a translating shuttle assembly secured within a slot in the column. An adjustable seat is supported by the shuttle assembly. A collar is secured to the upper end of the shuttle assembly, and circumscribes the column assembly in freely translating fashion. A first pivot shaft is joined to the collar to secure one end of a main drive link in freely pivoting fashion. A handle pivot shaft secures a pair of handle members to a second pivot shaft atop the column assembly. A first mounting pin is adapted to releasably secure the other end of the main drive link to the handles at selectively variable distances from the first pivot shaft. Movement of the handles urges the main drive link upwardly to lift the shuttle assembly and the weight of the user. A leg exercise assembly includes a pair of leg struts joined in parallel spaced apart disposition to opposed ends of a third pivot shaft supported on the column. The proximal ends of the leg struts are provided with pedals to engage the feet of the user. A pair of linking members extend from the distal ends of the leg struts and are releasably secured to proximal ends of the handle members. A second mounting pin is adapted to releasably secure the other end of the main drive link to the leg struts at selectively variable distances from the third pivot shaft. The user pushes downwardly on the pedals and lifts the handles. The compound action of the handle effort transmitted through the linking members to the leg struts, and the pedal effort transmitted through the main strut to the collar and the shuttle assembly, lilts the weight of the user. The handles are then pushed down by the user to continue the cycle by rotating the pedals upwardly and driving the shuttle assembly and seat downwardly. This cycle may be reiterated for aerobic activity.
