DETAILED DESCRIPTION OF THE INVENTION Fig. 1 is a schematic illustration of an exercise device 100 with two tracks (120,130), according to an exemplary embodiment of the invention. In an exemplary embodiment of the invention, tracks 120 and 130 are placed in a frame 110 to firmly support the tracks. In some embodiments of the invention, frame 110 is an open structure, for example metal bars welded together or pieces of wood. Alternatively or additionally, frame 110 includes an encasement enclosing tracks 120 and 130 from underneath and/or surrounding them from the sides.

In some embodiments of the invention, frame 110 is constructed from a material that induces friction (e.g. rubber) with common floor materials to prevent slippage during use. Alternatively or additionally, frame 110 may have attached supports or friction strips (e.g. from rubber or other materials) to prevent slippage.

In an exemplary embodiment of the invention, frame 110 includes a widened area 190 at one end of tracks 120, 130 or at both ends. Optionally, the widened area is large enough to allow a user to place a foot on widened area 190 while placing the other foot on platform 140. In some embodiments of the invention, the entire frame is wide enough to allow a user to place a foot on it.

In an exemplary embodiment of the invention, each track comprises two parallel rails (e.g. 122, 124) for accommodating a platform 140, which is adapted to travel on the track. In some embodiments of the invention, tracks 120, 130 may comprise more than two rails (e.g. 3 rails) or a single rail, for example supporting platform 140 through the middle. In an exemplary embodiment of the invention, platform 140 is adapted to glide over tracks (120, 130), for example using materials with a selected level of friction between them. In some embodiments of the invention, platform 140 comprises wheels or gears 180 to control its motion across tracks 120, 130.

In an exemplary embodiment of the invention, platform 140 is connected by a connection device such as an elastic rope or spring 160 to frame 110 to introduce a controllable force opposing movement of platform 140. In an exemplary embodiment of the invention, multiple connection devices, of the same or varying strength, are available to the user to connect between platform 140 and frame 110 so that the user may control the force required to move platform 140. Optionally, platform 140 is connected to frame 110 on one side of the platform or on both sides of the platform. In some embodiments of the invention, platform 140 can be connected by a single rope or spring or by multiple ropes or springs on the same side or on opposite sides in order to allow the user to enlarge or reduce the force required to move platform 140. Optionally, by connecting more ropes or springs between platform 140 and frame 110 the force required to move platform 140 a specific distance is enlarged.

In some embodiments of the invention, track 120 (or 130) or frame 110 comprise limiting holes 150, which are use to limit the path by which platform 140 can move. Optionally, by inserting a peg through one of holes 150 the useable length of track 120 (or 130) is shortened. In some embodiments of the invention, the track length available for platform 140 to move on may be set to zero.

In an exemplary embodiment of the invention, device 100 is a portable device so that it can be relocated and positioned by a single person. Optionally, the length of device 100 is selected to conform to the dimensions of a typical user, between one to two meters and its width is selected to be between half a meter to a meter. However larger or smaller sizes may be selected for implementing device 100. In an exemplary embodiment of the invention, device 100 may be manufactured in various sizes to fit the needs of different users. Alternatively, a single size may be used by different users by adjusting the track length as described above. In some embodiments of the invention, the device is easily assembled and disassembled for ease of transport and deployment. In an exemplary embodiment of the invention, device 100 weighs less than 50 Kg so that it may be transported by a single person or with the help of a second person. Alternatively, each part of device 100 may weigh less than 50 Kg so that it can be disassembled and transported by a single person. 173450/2 In an exemplary embodiment of the invention, frame 1 10 and tracks 120 and 130 are constructed from wood, metal, plastic or any other rigid material. Optionally, the material for constructing device 100 is selected according to the required strength and the desired weight.

In some embodiments of the invention, tracks 120 and 130 are contained in a single frame 1 10. Alternatively, each track may be contained in a separate frame and the two frames may be connected together along common points of contact, for example using connectors 170 to connect between two separate frames, each housing a single track. Optionally, connectors 170 may be screws, nuts and bolts, nails adhesives or other attachment devices.

In PCT application WO07089324, filed by the applicant on the same date as the current application, the disclosure of which is incorporated herein by reference, there is described various embodiments for implementing an exercise device with a platform that moves freely or with a constraint on a single track. Optionally, a dual track exercise device may be formed by physically connecting two independent single track devices as described in the PCT application or connecting other single track devices with platforms as known in the art. In an exemplary embodiment of the invention, a dual track device provides synergistic options for performing exercise which cannot be performed using a single track device, for example training two of a user's limbs simultaneously or performing exercises that require interaction between two users, which are each using one of the tracks or sharing tracks.

In an exemplary embodiment of the invention, a user exerts forces on one or more of platforms 140 that are deployed on tracks 120 and 130 in order to perform exercises. Fig. 2 is a schematic illustration 200 of the deployment and usage of an exercise device with two tracks, according to an exemplary embodiment of the invention. In an exemplary embodiment of the invention, a user may stand with one leg on platform 140 of track 120 and one leg on platform 140 of track 130. Optionally, the user holds on to an external apparatus, for example a ladder 210 as shown in Fig. 2, while moving his or her legs back and forth with platforms 140. It should be noted that there is no interaction between platforms 140 on the two tracks and the freedom of motion of platform 140 on each track and/or direction of resistance is controlled independently according to the constraints applied to the specific platform, for example level of friction between platform 140 and the track, the freedom of motion of the gears or wheels, and strength of the elastic rope or spring limiting the motion of the platform. Optionally, both platforms 140 may have an equal level of freedom of motion. Alternatively, one platform 140 may be set to require more force than the other to perform the same motion. In some embodiments of the invention, the required force is controllable for each platform, for example by connecting or disconnecting more constraints (e.g. more springs, or stronger springs).

Fig. 3 is a schematic illustration 300 of an alternative use of an exercise device with two tracks, according to an exemplary embodiment of the invention. Illustration 300 shows a user exercising both hands simultaneously by exerting force on platforms 140 of tracks 120 and 130. As mentioned above regarding Fig. 2, the amount of resistance of each, and direction of resistance of each platform 140 relative to its track is optionally, separately controllable.

Fig. 4 is a schematic illustration 400 of usage of an exercise device with two tracks by two users, according to an exemplary embodiment of the invention. In some embodiments of the invention, each track (120, 130) serves as an exercise device for a single user. Optionally, the users set exercise device 100 as desired or required to perform exercise with interaction between them, for example both tracks 120, 130 may be set with an identical constraint or different constraints on platforms 140 and the users may support each other or oppose each other by holding hands or interacting in other ways.

Fig. 5 is a schematic illustration of an exercise device 500 with two tracks of different length, according to an exemplary embodiment of the invention. In some embodiments of the invention, one of the tracks may serve for certain types of exercise or certain limbs while the other track may serve for other types of exercise or different limbs. Alternatively or additionally, the two tracks may differ in width or be comprised from a different exercise device. In some embodiments of the invention, one of the tracks may comprise more than one platform (e.g. 2 as shown in Fig. 5).

Fig. 6 is a schematic illustration of an exercise device 600 with two tracks positioned with an offset between their end points, according to an exemplary embodiment of the invention. In an exemplary embodiment of the invention, two identical tracks or tracks that differ in shape, for example length and or width may be combined with an offset between their end points along their longitudinal axis. Optionally, by combining two tracks with an offset and/or that differ in shape, further methods of muscle training may be implemented by one or two users.

Fig. 7 is a schematic illustration of an exercise device 700 with two tracks forming an angle 710 between the directions that the tracks extend, according to an exemplary embodiment of the invention. In some embodiments of the invention, the two tracks are connected with a pre-selected angle between them. Alternatively, the two tracks are connected by a hinge 720 with a pivot pin 740. In an exemplary embodiment of the invention, hinge 720 allows the two tracks to rotate relative to each other forming angle 710 between them. Optionally, exercise device 700 allows selecting any angle or specific angles between the two trades. In an exemplary embodiment of the invention, a stick 730 is connected between the two tracks (120, 130) to prevent a change in the angle between the two tracks.

In an exemplary embodiment of the invention, many exercises may readily be designed for optimally training selected muscles using a two track device in various forms such as described above.
