ABSTRACT:
A dual-purpose exercise machine, adapted to alternately condition two different sets of muscles, one device mode being for the legs and buttocks muscle sets (the foot stepper mode), and the other device position being for the pectoral/chest muscles and the upper arm muscles (biceps/triceps) in the bench press and ring extension modes. In the stepper mode, the device resembles a conventional stepping machine, having an upstanding vertical mast, conveniently formed by parallel elongate rigid members, set with a transverse span. A planar platform is securely mounted within the frame of the mast. An opposing pair of manual exertion resistance means, conveniently of hydraulic dampers, are disposed substantially horizontal, linked to the lever arms. They are mechanically linked to provide the variable resistance in opposition to alternating depression by user exerted upon foot-step platforms. When the platform component is inverted to lie in the bench press mode, the end spanning member forms the distal longitudinal end of the platform. A pair of transversely mounted gripping bar, which is vital to use of the machine, when it is in the bench press mode, are located on the lever arms ends.
