ABSTRACT:
An aerobic exercise device provides for a smooth, natural, orbital continuous motion of the user's feet. This device can be used for walking, running, jogging or stair-stepping exercises. Upper body workout devices can be provided with the aerobic exercise device such that a total body workout can be had. The device includes two parallel tracks with platforms. The platforms reciprocate along the tracks. A device is provided in each track for returning the platforms to the home position. As a user operates the device, he or she will push the platforms rearwardly. When the user's foot reaches the end of his or her stride, the user can then lift their foot in a natural motion. The device will return the platform to the home position. As the platform is returning to the home position, it will first travel in a forward direction and then switch to a rearward direction. This rearward movement will enable comfortable planting of the user's foot as it reengages the platform. The device can be easily accommodated to any desired workout level or to many different sized users.
