Abstract

An exercise device comprised of two independent, adjustable crank assemblies, a horizontal base and a centrally displaced pedestal. The first crank assembly is operated by the user's legs and includes two pivotally mounted pedals integrally attached to a crank system. The second crank assembly is operated by the user's arms and includes two pivotally mounted gripping means connected to a second, independent crank system. The resistance of the first and second crank assemblies are individually adjustable, enabling the user to employ varying levels of resistance to both his arms and legs. The centrally displaced pedestal functions as a means of support for the user's torso when the device is in use. The first crank assembly is attached to a generally vertical member, which vertical member is rigidly attached to the base. The second crank assembly is attached to a generally horizontal member, which horizontal member is adjustably mounted to the pedestal. The horizontal member is adjustable to a variety positions, enabling the user to operate the device in a generally horizontal position to a generally vertical position.

Dependent claims

An ergodynamically designed exercise device comprising:

a) a horizontal base having a leg extension integrally attached at an angular projection to one distal end and a vertical member integrally attached at a generally perpendicular projection near the opposite distal end;
b) wherein the leg extension comprises a first assembly having two first assembly pedals pivotally mounted to two first assembly cranks that are rotatably connected to opposite distal ends of a first assembly spindle, the leg extension further comprises a first assembly cable secured around a leg extension tension knob and a first assembly cog;
and
c) wherein the vertical member comprises a pedestal having a generally horizontal top planar comprises an arm extension adjustably and pivotally engaged to said vertical member by means of an arm extension pin, the arm extension has a second assembly having two second assembly grips pivotally mounted to two second assembly cranks that are rotatably connected to opposite distal ends of a second assembly spindle, the arm extension further comprises a second assembly cable secured around an arm extension tension knob and a second assembly cog said arm extension further comprising a means for supporting a user's torso wherein the arm extension is angularly adjustable with respect to said pedestal including a horizontal position which rests upon said planar surface.
