Abstract
A stationary exercising device which promotes cardiovascular exercise yet minimizes impact to critical joints. A base frame supports a pair of reciprocating members which are displaced in a horizontal direction parallel with the floor at one end yet reciprocate in a circular motion at the other end 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 the climbing exercise. This provides for more natural movement of the knee and ankle joints minimizing unnecessary stress on the joints yet permitting a cardiovascular workout. The device includes 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 arc or a substantially elliptical path, again promoting a more natural movement of the ankle, knee, elbow and shoulder joints and permitting a cardiovascular workout. The arm members are retractable.
