Computer directed exercising apparatus
First Claim
1. Exercising apparatus including:
- a stand;
first and second coupling units mounted on said stand displaced from one another along a horizontal axis, each of said coupling units being angularly adjustable about at least two axes to a multiplicity of positions to adapt the apparatus to a variety of different exercises;
a rotatable shaft extending along said horizontal axis between said first and second coupling units and connected thereto;
first and second crank arms respectively connected to said first and second coupling units, said first coupling unit being constructed so that rotation of said first crank arm in one direction exerts a torque on said one end of said shaft to cause said shaft to rotate in one direction, and said second coupling unit being constructed so that rotation of said second crank arm in said one direction exerts an opposite torque on the other end of said shaft to cause said shaft to rotate in the opposite direction.

Abstract
A mechanical and electronic apparatus which utilizes off-setting positive and negative muscle effort to provide a complete body muscle exerciser. The exerciser is constructed so that left side and right side symmetrical muscle groups are caused to work against one another, with one muscle group moving in extension providing resistance for the symmetrical muscle group to work thereagainst in contraction. A mechanical gear drive train is interposed between the opposing symmetrical muscle groups to transmit the forces exerted thereby, and to guide the user'"'"'s limbs so that the directions of motion are exactly opposite, and to assure that one muscle group contracts simultaneously with the extension of the other. Electrical sensors are coupled to the mechanical drive train to indicate the resistance being experienced by each muscle group; and also to indicate the position of the muscle groups, that is, the distance they have moved in their excursion. The electrical signals produced by the sensors are processed in a microcomputer which drives appropriate audio and visual displays.
