Definitions
- a lunge is a strength training or cardiovascular exercise traditionally performed without a machine and optionally performed with dumbbells, barbells, or just an exerciser's bodyweight.
- a lunge is performed with one leg and foot positioned forward with the knee bent and foot flat on the ground while the other leg and foot are positioned behind.
- the lunge primarily exercises and strengthens an exerciser's leg muscles, particularly the quadriceps and gluteal muscles, and the muscles comprising the hamstrings, semitendinosus, semimembranosus, and biceps femoris.
- a drawback of the traditional lunge is that an exerciser may perform a lunge in improper form, thereby decreasing the effectiveness of the exercise and increasing the risk injury.
- the present disclosure relates to exercise devices and methods of using such devices. More particularly, the disclosure provides lunge exercise devices, methods of performing lunges with such devices, methods of performing other low-impact exercises with such devices, and methods of achieving fitness and health goals using such devices and methods.
- the provided device and methods are configured to help a user perform a lunge exercise wherein the user's bodyweight is forced onto the heel of the user's forward foot (said foot frictionally engaged with the device) while impeding the ability of the user to put his or her bodyweight on the ball of said foot. Positioning bodyweight on the ball of a forward foot can cause a person performing a lunge exercise to stumble or actually fall over.
- the presently disclosed exercise device is configured to hold the user's forward foot steady and alleviate stress on the user's joints by enabling a smooth, fluid forward and reverse motion.
- the provided device is configured to hold a user's forward foot at one or more angles of incline while still impeding the ability of the user to position bodyweight on the ball of said foot.
- the provided exercise devices comprise at least one guide bar, at least one track operably connected to the guide bar, and a plate slidably engageable with the at least one track and reversibly moveable along the guide bar.
- the provided devices may further comprise one or more wheels slidably engageable with the at least one track.
- the wheels may be operably connected to the plate or operably connected to the at least one track.
- the track may, in some embodiments, comprise V-shaped edges, and the wheels may be rotationally engaged with the V-shaped edges of the track.
- a base may, in some embodiments, be engaged with the guide bar at or proximate to a first end of the guide bar.
- the first end of the guide bar may, in some embodiments, be elevated with respect to a second end of the guide bar, the second end being opposite the first end.
- a provided device may also comprise a base engaged with the guide bar at or proximate to the second end of the guide bar. Therefore, the first and second ends of the guide bar may, in some embodiments comprise a base. Each base is configured to provide stability to the guide bar by inhibiting rotational movement of the guide bar. Additionally, a base may be configured to elevate an end of the guide bar above a floor or other surface upon which the device is place. In other embodiments, a base may be configured to maintain an end of the guide bar substantially flat against the floor or other surface upon which the device is placed.

Rather, in such embodiments, the plate comprises one or more detachable surfaces, each detachable surface engageable with a plate base portion and providing a different angle of incline. Accordingly, the plate may be reversibly adjusted—through the substitution of one or more detachable surfaces—to have an incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°.
- a first detachable surface engaged with the plate base portion may provide an incline angle of 5°, and if an angle of 10° is desired, the first detachable surface may be removed and substituted with a second detachable surface that engages the plate base portion and provides an incline angle of 10°.
- the plate comprises an adjustable incline angle but achieves such angle by different means.
- the plate itself may be detachable from the track and guide bar, thereby allowing for the substitution of a different plate.
- the device may—in some embodiments—comprise one or more detachable plates, each plate providing a different angle of incline. Accordingly, the device plate may be reversibly adjusted—through the substitution of one or more plates—to have a plate incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°.
- a first detachable plate may be substantially flat, and if an incline angle of 10° is desired, the first detachable plate may be removed from the device and substituted with a second detachable plate that provides an incline angle of 10°.
- methods of performing an exercise comprise providing an exercise device as disclosed herein, placing a first foot on a plate of the device and a second foot on a ground surface proximately lateral to the plate, extending the plate forward along the guide bar with the first foot, and applying pressure with the first foot sufficient to reverse the course of the plate along the guide bar.

Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 13/775,617, filed Feb. 25, 2013, and claims the benefit of priority under 35 U.S.C. Section 119(e) of U.S. Provisional Patent Application No. 61/823,082, filed May 14, 2013, both of which are hereby incorporated by reference in their entireties.
- A lunge is a strength training or cardiovascular exercise traditionally performed without a machine and optionally performed with dumbbells, barbells, or just an exerciser's bodyweight. Traditionally, a lunge is performed with one leg and foot positioned forward with the knee bent and foot flat on the ground while the other leg and foot are positioned behind. The lunge primarily exercises and strengthens an exerciser's leg muscles, particularly the quadriceps and gluteal muscles, and the muscles comprising the hamstrings, semitendinosus, semimembranosus, and biceps femoris. A drawback of the traditional lunge is that an exerciser may perform a lunge in improper form, thereby decreasing the effectiveness of the exercise and increasing the risk injury.
- The present disclosure relates to exercise devices and methods of using such devices. More particularly, the disclosure provides lunge exercise devices, methods of performing lunges with such devices, methods of performing other low-impact exercises with such devices, and methods of achieving fitness and health goals using such devices and methods.
- In some embodiments, the provided device and methods are configured to help a user perform a lunge exercise wherein the user's bodyweight is forced onto the heel of the user's forward foot (said foot frictionally engaged with the device) while impeding the ability of the user to put his or her bodyweight on the ball of said foot. Positioning bodyweight on the ball of a forward foot can cause a person performing a lunge exercise to stumble or actually fall over. The presently disclosed exercise device is configured to hold the user's forward foot steady and alleviate stress on the user's joints by enabling a smooth, fluid forward and reverse motion. Additionally, in some embodiments, the provided device is configured to hold a user's forward foot at one or more angles of incline while still impeding the ability of the user to position bodyweight on the ball of said foot.
- In some of the various embodiments, the provided exercise devices comprise at least one guide bar, at least one track operably connected to the guide bar, and a plate slidably engageable with the at least one track and reversibly moveable along the guide bar. The provided devices may further comprise one or more wheels slidably engageable with the at least one track. The wheels may be operably connected to the plate or operably connected to the at least one track. The track may, in some embodiments, comprise V-shaped edges, and the wheels may be rotationally engaged with the V-shaped edges of the track. A base may, in some embodiments, be engaged with the guide bar at or proximate to a first end of the guide bar. The first end of the guide bar may, in some embodiments, be elevated with respect to a second end of the guide bar, the second end being opposite the first end. A provided device may also comprise a base engaged with the guide bar at or proximate to the second end of the guide bar. Therefore, the first and second ends of the guide bar may, in some embodiments comprise a base. Each base is configured to provide stability to the guide bar by inhibiting rotational movement of the guide bar. Additionally, a base may be configured to elevate an end of the guide bar above a floor or other surface upon which the device is place. In other embodiments, a base may be configured to maintain an end of the guide bar substantially flat against the floor or other surface upon which the device is placed. In some embodiments, the provided device may have one or both types of disclosed bases. For example, one end of the guide bar may comprise one type of base and the other end may comprise the same or different type of base. Additionally, in some embodiments, a bottom surface of the guide bar is engaged with a top surface of the base through a fastener engagement.
- In some embodiments, a first portion and a second portion of each wheel may have the same or different radii, both of such radii being greater than the radius of a third portion of each wheel. In such embodiments, the first and second portions of each wheel inhibit substantially perpendicular movement of the plate with respect to the guide bar, and the third portion of each wheel receives a V-shaped edge of a track.
- In some embodiments, the plate has a substantially flat surface opposite the side facing the track and guide bar. In other embodiments, the surface opposite the side facing the track and guide bar comprises an angle of incline. Whether having a substantially flat or an angle of incline, the plate surface opposite the side facing the track and guide bar has dimensions suitable for receiving a bottom of a user's foot.
- In some embodiments, the plate is configured to reversibly adjust from being substantially flat to having an incline by raising or lowering a first plate end relative to a second plate end. For example (and without intending to be limited), the plate may adjust to have an incline angle of 1-30°. Accordingly, the plate may be adjusted to have an incline of 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°.
- In some embodiments, the plate does not have a first end that adjusts relative to a second end but nevertheless comprises an adjustable incline angle. In such embodiments, the plate comprises one or more stackable surfaces, each surface providing a greater angle of incline than the immediately preceding surface. Each stackable surface either engages a base portion of the plate or the top of a stackable surface already engaged with the plate base portion. The base portion may, in some embodiments, be substantially flat. The plate may be reversibly adjusted—through the addition or removal of one or more stackable incline surfaces—to have an incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. For example, the plate may comprise two stackable incline surfaces, the first incline surface engaged with the base plate portion and providing an incline angle of 5°, and the second incline surface engaged with the top of the first incline surface and providing an additional incline angle of 5°, thereby resulting in a plate having an inclined surface with a cumulative incline angle of 10°.
- In yet other embodiments, the plate comprises an adjustable incline angle but does not have a first end that adjusts relative to a second end nor does it comprise one or more stackable surfaces. Rather, in such embodiments, the plate comprises one or more detachable surfaces, each detachable surface engageable with a plate base portion and providing a different angle of incline. Accordingly, the plate may be reversibly adjusted—through the substitution of one or more detachable surfaces—to have an incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. For example, a first detachable surface engaged with the plate base portion may provide an incline angle of 5°, and if an angle of 10° is desired, the first detachable surface may be removed and substituted with a second detachable surface that engages the plate base portion and provides an incline angle of 10°.
- In further embodiments, the plate comprises an adjustable incline angle but achieves such angle by different means. In such embodiments, the plate itself may be detachable from the track and guide bar, thereby allowing for the substitution of a different plate. Accordingly, the device may—in some embodiments—comprise one or more detachable plates, each plate providing a different angle of incline. Accordingly, the device plate may be reversibly adjusted—through the substitution of one or more plates—to have a plate incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. For example, a first detachable plate may be substantially flat, and if an incline angle of 10° is desired, the first detachable plate may be removed from the device and substituted with a second detachable plate that provides an incline angle of 10°.
- In some of the various embodiments of the present disclosure, also provided are methods of performing an exercise. Such methods comprise providing an exercise device as disclosed herein, placing a first foot on a plate of the device and a second foot on a ground surface proximately lateral to the plate, extending the plate forward along the guide bar with the first foot, and applying pressure with the first foot sufficient to reverse the course of the plate along the guide bar. In the performance of such exercise, a first knee, a second knee, or both, may be bent during the extension of the plate forward along the guide bar. Additionally, a user's bodyweight may be maintained with a frictional engagement between a heel of the first foot and the plate during performance of at least a portion of the exercise. Moreover, in those embodiments wherein a first knee, second, knee, or both, are bent during performance of the exercise, the method may further comprise straightening the first knee, second knee, or both as the plate is reversed along the guide bar. In some embodiments, the exercise performed is a lunge, and is performed in a manner suitable for achieving fitness and health goals of a user.

This engagement lifts the first end of the guide bar to at least the height of the base while the second end of the guide bar remains engaged with a surface, such as the ground, upon which the device is placed. The height of the base is variable. As non-limiting examples, the top surface of the base may be 0-1 inch, 1-2 inches, 2-3 inches, 3-4 inches, 4-5 inches, or 5-6 inches above the surface upon which the device is placed. The resulting incline means that the plate moves, in some embodiments, up an incline during the performance of a lunge.
- In some embodiments, the engagement of the top surface of the base and the bottom surface of the guide bar maintains one or both ends of the guide bar substantially proximate to the floor or other surface upon which the device is placed. In such embodiments, the base is configured to lower the center of gravity of the device, thereby inhibiting rotational movement of the guide bar. As one non-limiting example, the base may comprise one or more substantially flat bars or tabs. As one of skill will appreciate, in such configuration, the device does not achieve an incline through the base, guide bar, or combination thereof. Rather, the guide bar is maintained substantially flat against the surface (such as floor) upon which the device is placed.
- In some embodiments, it may be desirable for the provided device to have an incline. The incline results in the user's bodyweight being placed on the heel of the user's engaged foot and discourages the user from positioning bodyweight onto the ball of said foot. A lunge performed with a user's bodyweight on the ball of the forwardly placed foot can cause the user to stumble or fall over. By positioning bodyweight on the heel of the engaged (forward foot on the plate) throughout the lunge, the user may prevent joint stress and strain that may be caused by an improper lunge. Moreover, by performing a lunge in proper form, the user may better achieve health and fitness goals.
- In those embodiments where an incline is desired, the provided device can be configured to have an incline through the combination of a base and guide bar, as previously described. Alternatively, the device may achieve an incline through the one or more plates of the device. In some embodiments, the plate is configured to reversibly adjust from being substantially flat to having a desired incline. For example (and without intending to be limited), the plate may adjust to have an incline angle of 1-30° by raising a first end of the plate relative to a second end of the plate. Accordingly, the plate may be adjusted to have an incline of 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. In such embodiments, the plate comprises a means for maintaining the incline of the plate. For example, the plate may comprise a hinge mechanism, a kickstand mechanism, a detent mechanism, a ratchet mechanism, a jack mechanism, a caliper mechanism, a screw mechanism, a pin mechanism, or other suitable mechanism.
- In other embodiments, the plate comprises one or more stackable surfaces in order to achieve a desired incline, each stackable surface providing a greater angle of incline than the immediately preceding surface. Accordingly, the plate may be reversibly adjusted—through the addition of one or more stackable incline surfaces—to have an incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. For example, the plate may comprise two stackable incline surfaces, the first incline surface engaging at least a portion of a plate base portion and providing an incline angle of 5°, and the second surface engaging at least a portion of the first incline surface and providing an additional incline angle of 5°, thereby resulting in a plate having an inclined surface with an incline angle of 10°.
- In yet other embodiments, the plate comprises one or more detachable surfaces in order to achieve a desired incline, each detachable surface providing a different angle of incline. Accordingly, the plate may be reversibly adjusted—through the substitution of one or more surfaces—to have an incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. For example, a first detachable surface may engage at least a portion of a plate base portion and provide an incline angle of 5°. If a user desires an angle of 15°, the first detachable surface may be completely removed from the plate and substituted with a second detachable surface that provides an incline angle of 15°.
- In further embodiments, the plate itself may be detachable from the track and guide bar, thereby allowing for the substitution of a different plate in order to achieve a desired incline. Accordingly, the device may—in some embodiments—comprise one or more detachable plates, each plate providing a different angle of incline. Accordingly, the device may be adjusted—through the substitution of one or more plates—to have a plate incline of (without intending to be limited) 1°-5°, 5°-10°, 10°-15°, 15°-20°, 20°-25°, 25°-30°. For example, a first detachable plate may be substantially flat. If a user desires an incline of 10°, the first detachable plate is completely removed from the device and substituted with a second detachable plate having an incline angle of 10°.
- As indicated, in some embodiments, the disclosed device provides an incline. This incline, combined with other elements of the device, may induce a user to perform a lunge in proper form. Each lunge performed in a proper form more effectively stimulates the muscles of the leg, particularly the quadriceps and gluteal muscles, and the muscles comprising the hamstrings, semitendinosus, semimembranosus, and biceps femoris. Performing a proper lunge may enable the user to achieve health and fitness goals.
- In some embodiments, the plate—whether substantially flat, or comprising at least one inclined surface through a variety of disclosed means—may take a variety of shapes. These shapes may include a square, a rectangle, a triangle, a circle, or a variety of rounded or pointed shapes, including a shape substantially similar to the bottom of a shoe or a foot. In other embodiments, the plate may have a contoured, dimpled, ridged, roughened, or other surface type and may take a variety of shapes. Regardless of shape or surface type, the plate has a surface with dimensions suitable for receiving at least a portion of a bottom of a user's foot.
- In some embodiments, multiple tracks are operably connected to the guide bar, each tack comprising at least one V-shaped edge. In other embodiments, the track is one integral track operably connected to the guide bar and comprising at least one V-shaped edge. In some embodiments, each V-shaped edge is located proximate to the intersection of the top and lateral surfaces of a guide bar having a substantially square or substantially rectangular cross-section. The connection of the at least one track to the guide bar may be a fastener engagement as described elsewhere herein.
- In some embodiments, at least one wheel is rotationally engaged with a track, the engagement being on at least one side of the guide bar. At least one track further comprises at least one V-shaped edge and the wheels independently rotationally engage the track at the V-shaped edge. In some embodiments, the wheels each comprise a first portion, a second portion, and a third portion. In some embodiments, the first portion of each wheel corresponds with a top portion of the wheel, the second portion of each wheel corresponds with a bottom portion of the wheel, and the third portion of each wheel corresponds with a center portion of the wheel. In some embodiments, the first portion and the second portion of each wheel have substantially equivalent radii. In some embodiments, the third portion of each wheel has a smaller radius than the radius of both the first portion and the second portion of each wheel. In some embodiments the rotational engagement between each wheel and a V-shaped edge of the track occurs at the third portion of each wheel, said portion being configured to receive at least a portion of such V-shaped edge. In some embodiments, this wheel structure comprising a third portion with a radius that is smaller than the radius of both the first portion and the second portion prevents substantially perpendicular movement of the plate with respect to the guide bar.
- In other embodiments, the wheels may maintain a uniform radius or any other shape to allow a rotational engagement with the track in a variety of manners. For example, the track may comprise at least one groove to allow rotational engagement between one or more wheels and a groove or grooves of the track. In other embodiments, at least one wheel may have a magnetic engagement with the track or the guide bar. In some embodiments, the wheels comprise steel or a functionally similar material of construction.
- In some embodiments, the plate is able to move along a length of the guide bar, the length comprising a distance from a first position of the guide bar to a second position of the guide bar. This length comprises a length of the track, but in some embodiments is not equivalent to the total length of the guide bar. In some embodiments, a first stopper is attached to the guide bar at the first position of the guide bar, a second stopper is attached to the guide bar at the second position of the guide bar, or the first and second stoppers are both attached as described. Each stopper is configured to restrict the slidable movement of the plate along the guide bar at the first position of the guide bar, at the second position of the guide bar, or both. In some embodiments, each of the stoppers may comprise a variety of materials, including rubber, steel, aluminum, plastic, synthetic, or any functional equivalent. In some embodiments, at least one stopper is located proximate to an end of a guide bar.
- Instead of one or more stoppers, or in combination with one or more stoppers, the movement of the plate along a length of the guide bar may be restricted by an adjustable locking mechanism. Accordingly, in some embodiments, the device comprises an adjustable locking mechanism attached to, or otherwise engageable with, the guide bar, said mechanism being configured to restrict the slidable movement of the plate along the guide bar in a reversible and user-customizable manner. For example, a user may move the mechanism to a first position along the guide bar such that one or more lunges may be performed at a first maximum length. Next, the user may move the mechanism to a second position along the guide bar such that one or more lunges may be performed at a second maximum length. The first maximum length may be greater than or less than the second maximum length. Without intending to be limiting, examples of suitable locking mechanisms include pins, rods, cleats, and clamps. In some embodiments, the locking mechanism may be configured to slidably engage with the one or more tracks, thereby enabling a user to adjust the mechanism by, among other actions, sliding the mechanism along the one or more tracks to a desired position. One of skill will appreciate that the track, guide bar, or both will, in such embodiments, have along its length apertures, holes, ridges, or other means for allowing the slidable locking mechanism to lock into place. In some embodiments, instead of being slidably engageable with the one or more tracks, the locking mechanism is configured to be inserted into one or more apertures, holes, ridges, or other engagement means formed into the guide bar. For example, in embodiments where the locking mechanism is a pin, the guide bar comprises one or more holes along its length, each hole configured to receive the pin. The one or more holes may be located between two tracks (i.e., vertical insertion) or along the side of the guide bar (i.e., horizontal insertion).
- In some of the various embodiments of the present disclosure, provided are methods of performing exercises and methods of achieving a user's health and/or fitness goals. One such method is a method of performing lunges comprising the steps of: placing a first foot on a plate, placing a second foot on a ground surface next to the plate, extending the plate forward along a guide bar with the first foot while maintaining a frictional engagement between a heel of the first foot and the plate, and applying sufficient pressure to the plate with the first foot to reverse the course of the plate. While extending the plate forward, the user may also bend a first knee, a second knee, or both. Similarly, while reversing the plate, the user may straighten the first knee, the second knee, or both. Moreover, the user may maintain bodyweight on the heel of the foot engaged with the plate during performance of the exercise. In some embodiments, the user may adjust the incline of the plate by raising or lowering one end of the plate, by adding one or more stackable surfaces to the plate, by changing a detachable surface of a plate, or by substituting another plate. In some embodiments, the user may adjust the stride length by adjusting placement of one or more adjustable locking mechanisms along the length of the guide bar.
