Shock-free aerobic and anaerobic exercising machine for use in the

Abstract

A shock-free exercising machine, which can be used by the young and elderly, the small and large structured person, and the inexperienced and experienced exerciser for both aerobic and anaerobic exercise, that provides a rhythmic fluid motion to the body of the user and particularly to the legs, pelvis and spine which is completely free of shock and impact stress on the joints, bones and muscles in which, at all times, the user remains in an upright standing position. In one embodiment the exercise simulates climbing motion of the user's legs with synchronized push-pull motion of the user's arms. On one embodiment the exercising machine comprises a base member; a vertical frame member fixedly attached there, right and left lower levers pivotally mounted on the lower part of the vertical member, the free ends the levers for standing on; right and left upper levers pivotally mounted on the upper part of the vertical member; right and left tie rods pivotally mounted at the upper distal ends thereof to the right and left upper levers, respectively, and pivotally mounted at the lower distal ends thereof to the right and left lower levers, respectively; rocker arm assembly for synchronizing the movement of the lower levers so that when one lower lever moves downwardly the other one moves upwardly; and shock-free resistance system for resisting the movement of at least one of the levers.
