## Background
TECHNICAL FIELD
The present invention technically relates to systems, apparatuses, devices, and methods for exercising. More particularly, the present invention technically relates to systems, apparatuses, devices, and methods for exercising multiple muscle groups. Even more particularly, the present invention technically relates to systems, apparatuses, devices, and methods for exercising multiple muscle groups simultaneously.
BACKGROUND ART
Various related art systems, apparatuses, and methods for facilitating arm and leg exercises exist. One such apparatus comprises an arm/leg push/pull exercise device where the arms and legs of the user are connected by cables and pulleys and the user engages the device in an upright manner. The device also includes rolling foot supports that connect to an anchor. Some other current related art inventions include: a leg exercise device having foot supports that move along repositionable tracks, wherein the foot supports are connected to a resistance system, and wherein the tracks have a structure for preventing the movement of the foot supports; an exercise apparatus wherein a user's arms and legs are connected by a system of straps and pulleys, and wherein the user engages the exercise device while standing; a push/pull exercise device, wherein a user's arms and legs are connected by a system of lines and pulleys, and wherein the user engages the exercise device while standing; and an exercise apparatus for simulating skating having rotatable foot pedals for altering the type of motion and a resistance device that resists the movement of the pedals.
Yet other related art inventions include: an apparatus for training a user to perform proper body movements, wherein the device is a frame having bands connected to a harness on a user's body that restrains the user's movement into appropriate directions; an exercise device for people who have suffered from attacks or paralysis, wherein the device is a frame, and wherein a set of rotating pedals are connected to a pair of cables by a pulley system for moving the user's arms up and down; a push/pull exercise device, wherein the user's arms and legs are connected by ropes and pulleys, and wherein the user performs the exercises while in a prone position; and a system of ropes, pulleys, and counterweights that aid a user in performing exercises of varying difficulties.
However, these related art systems, apparatuses, and methods do not provide any adjustable resistance for exercising multiple muscle groups simultaneously. These related art exercise systems typically employ spools, which tend to lose energy through its reels, the energy being supplied by forces exerted by the exerciser's limbs, thereby rendering the system inefficient, especially for isometric exercise. Thus, a need is seen to exist for a device and corresponding methods which provide adjustable resistance or conserved energy resistance for exercising multiple muscle groups simultaneously.
DISCLOSURE OF THE INVENTION
The present invention addresses the needs in the related art in a device and corresponding methods which provide adjustable resistance or conserved energy resistance for exercising multiple muscle groups simultaneously. The present invention promotes strength, toning, and flexibility of major muscle groups in the inner and the outer leg through a combination of elements which facilitates divergent as well as convergent motions. In contrast to the related art systems, apparatuses, and methods, the present invention pulley system transfers energy directly from one limb to another from forces exerted by the exerciser's limb, wherein energy loss is minimized in the device, thereby rendering the device efficient, especially for an isometric exercise. As such, not only are the limbs exercised simultaneously in the present exercise device, they are also exercised dependently.
The present invention exercise device generally comprises: a frame; a track being mechanically coupled to the frame; and a plurality of platforms for accommodating an exerciser's feet, each platform of the plurality of platforms comprising at least one moving member, such as at least one wheel, for facilitating both a divergent movement and a convergent movement, the at least one moving member moving on the track.
