Abstract
Abstract A mobile exercising apparatus which promotes cardiovascular exercise yet minimizes impact to critical joints. A frame supports a pair of reciprocating members which are displace generally horizontally along the frame at one end yet reciprocate in a circular motion at the other through a coupling system attached to the frame. Structure is included which permits each foot of the user to move in a generally elliptical path during exercise and drive a wheel thereby propelling the apparatus. This allows simulation of walking or running without impact. The device may include linkage to facilitate a corresponding upper body exercise involving movement of the arm in which case each hand of the user is displaced along an arcuate path.
