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.

[ I claim:] [1.] A foot-stepping exercise device comprising a hand grippable first component disposed at one longitudinal end of the device and a second floor contacting component disposed proximal to the other longitudinal end thereof and consisting essentially of:a. an elongate, generally rectangular platform member adapted to extend between and conjoin the first component and the second component, and being rotatably pinned to the second component and which platform is substantially vertically inclined so as to confront the standing erect device user;b. the hand grippable first component comprises a generally rectangular rigid component anchored transversely at the first longitudinal end of the platform member and with its plane also disposed at an outward angle relative thereto, so that the first component projects outwardly of the plane of the platform member;c. the second floor contacting component which comprises a generally H-shaped rigid frame composed of a first and second substantially parallel elongate elements and at least one transversely interconnecting first linear element, with all three elements underlying and supporting the platform member;d. a second linear member disposed transversely between the first and second elongate members and located longitudinally offset from the first linear member;e. a pair of spaced apart, upright posts suspended from and located along opposing sides of the elongate elements of the platform component, with each post also being located proximal to the outer longitudinal ends of the third second linear member element and with each post adapted to pivot about a horizontal axis;f. a pair of lever members, with each member pivotally pinned at one longitudinal end to the upper longitudinal end of its respective upright post, with the lever arm, adapted to project the free lever arm ends variably vertically and arcuately along the device longitudinal sides;g. a pair of limb contactable, rotatable fixtures, each fixture axially and pivotally pinned to the outer free ends of its respective lever member, with each rotatable fixture presenting a generally planar stepping element on one surface, and having an hand grippable bar on an opposing surface; and,h. a pair of biasing means for the lever members, parallel and spaced apart, with each of the biasing means pivotally anchored between one of the elongate elements of the floor supporting H-frame, and concurrently linked to the lower longitudinal end of its associated pivotable upright post, also with each of the biasing means adapted to offer mechanical resistance to the arcuate movement in reciprocal directions of the planar stepping element of the associated rotatable fixture, and with each biasing means moving in response to the foot stepping efforts imposed by the device user upon the rotatable fixture supported by the associated pivoting lever member.
