Description

BICEPS EXERCISE DEVICE AND METHODS OF USE

This application is a non-provisional of and claims the benefit of U.S. Provisional Application No. 62/981 ,117 filed on February 25, 2020, which is incorporated herein by this reference in its entirety; this application is also a continuation-in-part of US Design Application No. 29/737,183 filed on June 5, 2020, and is also a continuation-in-part of US Design Application No. 29/760,776 filed on December 3, 2020, which are both incorporated herein by this reference in their entireties. BACKGROUND OF THE INVENTION

The present invention relates to exercise equipment, and more particularly to apparatus and methods for exercising human biceps.

A biceps curl is a single-joint exercise for building bigger and stronger biceps. Many people training their biceps have a difficult time performing bicep exercises that target the biceps without significant forearm muscle activation. Forearm muscle activation while performing a bicep training exercise can negatively impact the levels of tension placed upon the biceps (reduces bicep isolation) and reduces the effectiveness of biceps training exercises overall. A known bicep exercise called the “waiters curl” is performed by orienting a dumbbell with weights at either end in a vertical position, and placing the hands underneath a flat underside of a weight at an upper end of the dumbbell, with the wrists bent forward away from the body. The positioning of the hands and wrists in this manner (similar to the position of a waiter’s hand under a tray) de-emphasizes the involvement of the forearm muscles and places very direct and continuous tension on the biceps throughout the exercise. The dumbbell is raised by pressing upwards with the palms which forces consistent supination when the movement is performed while keeping the top, flat side of the dumbbell parallel to the ground.

However, because the size of a typical dumbbell head varies with the size of the weight, the “waiters curl” exercise can be difficult to perform properly with smaller, lighter weights. Frequently there is not enough surface area underneath the dumbbell weight for the palms to be flat, resulting in some gripping by the fingers and unwanted involvement of the forearm muscles. The dumbbell waiters curl also only allows for very narrow hand positioning and cannot be performed with resistance bands, kettlebells, or cable machines.

It is therefore desirable to provide improved methods and apparatus for use in exercising human biceps that target the biceps without significant forearm muscle activation. It is also desirable to provide methods and apparatus for exercising other human muscles. SUMMARY OF THE INVENTION

Embodiments of the present invention provide methods and apparatus that enable a person to perform a variety of muscle strengthening exercises. Embodiments of the present invention also provide methods and apparatus that enable a person to perform a biceps training exercise having the effectiveness of a “waiter’s curl” that directly targets the biceps yet minimizes activation of the forearm muscles, while also affording a more comfortable, stable grip, increased variations related to hand positioning, and the ability to utilize multiple forms of resistance (such as, without limitation, cable machines, resistance bands, kettlebells). Embodiments of the invention afford a user with the ability to utilize a single dumbbell in conjunction with embodiments of the invention to target both biceps simultaneously. In some embodiments, an exercise / resistance band may also be attached to different embodiments of apparatus of the invention while performing exercises, allowing the exercise to then be performed with or without an inserted dumbbell. A non-exclusive example of a resistance band may include an elastic band used for strength training which may use a carabiner type of mechanism to attach the band to a variety of attachment devices (for example, handles).

Embodiments of the invention also enable a user to utilize an attachment mechanism in conjunction with embodiments of apparatus of the invention to utilize kettlebells, cable machines, resistance / exercise bands to provide a means of resistance while performing an exercise using such embodiments.

In embodiments of an apparatus of the invention, a movable hand-held board or platform is provided having an upper and a lower surface, a front side or edge, a back side or edge, and left and right sides or edges. The front and back sides may be longer than left and right sides. A centrally located slot is provided in either the front or back side for receiving a handle or crossbar of a dumbbell. The surfaces of the platform on either side of the slot should each be large enough to receive an open palm of a human hand. Embodiments of the slot should be just wide enough to receive the dumbbell handle or crossbar, but narrow enough to prevent the crossbar from moving or wiggling within the slot, and should also prevent any weight(s) on the dumbbell from slipping through the slot. The platform should have a width or thickness that provides sufficient strength to support a dumbbell or other object having a significant amount of weight attached to it. By way of example, and without limitation, in some embodiments the platform thickness may be from one-eighth inch (1/8”) up to one and one-half inches (1- 1/2”), depending on the strength of the material used. A suitable thickness for a wooden or plastic platform in embodiments of the invention may be in the range of one-half inch (1/2”) to one inch (G). For metallic embodiments of the platform, the thickness may be the same as or less than for wooden or plastic embodiments, in the range of one-quarter inch (1/4”) to one inch ( ).

In some embodiments, a peripheral ridge or lip may be provided on the upper surface of the platform. In these embodiments, the central portion of the platform may have a thickness that is less than that of the peripheral ridge.

In some embodiments, one or more recesses may be provided on the upper surface of the platform adjacent to the slot to receive a side edge of a dumbbell weight in order to help prevent the weight from shifting in the slot during use. In some embodiments, one or more upwardly extending ridges may be provided on the upper surface of the platform to engage a side edge of a dumbbell weight in order to help prevent the weight from shifting in the slot during use.

In some embodiments, openings may be provided in the platform on either side of the slot to receive the hands or fingers of the user, allowing the user to grip the platform from underneath while in use. In some embodiments, one or more upwardly extending protrusions or tabs may be provided on the upper surface of the platform along or adjacent to the slot to help prevent the dumbbell from sliding out of the slot during use.

In some embodiments, a latching mechanism may be provided at the edge of the slot to help prevent the dumbbell from sliding out of the slot during use.

In some embodiments, a pair of openings or eyelets may be provided on left and right sides of a platform of the embodiment, for receiving elastic or rubberized resistance bands, the ends of weight cables, or other resistance devices that may be engaged with the platform. In these embodiments, instead of the weight of a dumbbell, resistance is provided by the resistance bands, cables or other devices.

In some embodiments, a multi-use adapter may be provided. One end of an embodiment of such an adapter (a “puck”) may engage with a slot of a platform of an embodiment of the invention. The opposite end of the adapter may comprise an opening, clip, hook, strap, or other suitable engagement device for attachment to one or more weights, resistance bands, springs, or other tension imparting devices, or for attachment to one or more cords, ropes, cables or belts leading to such a tension imparting device.

It is to be appreciated that in alternative embodiments, equipment other than a dumbbell may be engaged in the slot of embodiments of the invention. For example and without limitation, a plate or ball, a resistance band, a spherical or looped component, a cable from a weight machine, or other resistance imparting devices may be engaged in the slot, instead of a dumbbell, to provide resistance during exercise. The resistance provided by these alternative components may be varied according to their size and the desires of the user. In some embodiments, these alternative components may be attached to exercise bands or otherwise tethered or anchored to other structures to provide additional resistance during exercise. By way of example, and without limitation, in embodiments of the invention, a platform may be provided that is oriented in a horizontal position, and a dumbbell having selected weights on both ends is oriented in a vertical direction, allowing the handle or crossbar of the dumbbell to be slidably engaged with a slot of the platform by being slid to the closed end of the slot. Once the crossbar is engaged with the slot, this causes a weight at one end of the dumbbell to come into contact with the upper surface of the platform, while the crossbar extends downward from the platform to the weight (dangling) at the opposite end. This causes the platform to support the heavy weight of the entire dumbbell and crossbar. It is to be appreciated that the amount of weight supported by the platform may be selected and adjusted by the user according to the weight of the dumbbell, and/or how much weight, if any, is placed on the dumbbell.

In one exemplary exercise, the user may place the palms of both hands on the lower surface of the horizontally oriented platform with palms facing up (underneath the platform) on either side of the dangling dumbbell. It is to be appreciated that since no gripping is necessary, the fingers and forearms are not implicated by this positioning. Supporting the platform in this way will transfer tension to the user’s biceps, allowing the biceps to be exercised by raising and lowering the weighted platform, without significantly affecting the user’s forearms. It is to be appreciated that other means of providing resistance other than a dumbbell may be used, and that muscles other than the biceps may be exercised using embodiments of the invention.

In another example and without limitation, a user may rotate a single dumbbell to a vertical position, and then slide the handle of the dumbbell into an insertion slot of horizontally oriented embodiments of a board of the invention. One end of the dumbbell rests on the top side of board and the user’s hands are placed on the underside of the board (palm side up) which allows the dumbbell to be suspended from the board. In some embodiments, as the dumbbell’s handle is slid into the dumbbell insertion slot, a spring-loaded safety latch at an edge of the slot is pushed inwards from a closed position allowing the handle to slide past the safety latch. Once the handle is inserted past the safety latch, the safety latch springs back to a closed position preventing the dumbbell from falling out if the board is tilted towards the opening of the dumbbell insertion slot.

In order to perform a bicep curl exercise using embodiments of the above example, an inserted dumbbell is suspended by the horizontally oriented platform or board with the user’s palms (facing up) supporting the board, so that the board is in a position that is generally parallel to the floor. The user has the option of placing the hands at varied widths apart on the underside of the board. The palms remain in a position parallel to the floor while holding the board. The initial top position of the board may be approximately across from the user’s shoulders. As the user lowers the board, the user seeks to maintain the board in a parallel position to the floor at all times, lowering the board until it is approximately across from the user’s waist. At this bottom position of the movement, the user still maintains the board in a parallel position to the floor. The user then repeats the movement by raising the board and returning to the top position of the movement (across from the shoulders), always with an emphasis on keeping the board parallel to the floor during the exercise. It is to be noted that in the top position, the user’s hands are flat on the bottom side of the board and the wrists are bent forward away from the user’s body.

Embodiments of the invention may also be used to perform front deltoid shoulder raises. In these embodiments, the user may start in the same position used to perform a curl exercise described above with a single dumbbell inserted into a slot of a board of an embodiment of the invention. However, instead of performing a curl movement, the user keeps the arms straight (elbows locked) with the board starting at a position across from the user’s waist, or slightly lower. The user then raises the board outwards and upwards in front of the body until it is approximately across from the shoulders. The user then lowers the board and inserted dumbbell in the same manner and repeats the movement for multiple repetitions, preferably while maintaining the board parallel to the floor as much as possible.

By way of another example, and without limitation, embodiments of the invention may be used to perform a pull over exercise. In these embodiments, a single dumbbell is inserted into a slot of a board of an embodiment of the invention. The user lies on their back on a bench press or other raised surface, with arms outstretched above the head so that they are parallel to the user’s body in a horizontal position. The board with dumbbell is held in a horizontal orientation with open palms on the lower surface. The user then raises the platform by rotating the shoulders until the arms are nearly vertical, such that the platform is above the user’s head, still holding the platform in a generally horizontal orientation. The platform is then lowered back behind the user’s head to the starting position, after with the process is repeated. By way of another example, and without limitation, embodiments of the invention may be used to perform a spider curl exercise. In these embodiments, a single dumbbell is inserted into a slot of a board of an embodiment of the invention. The user leans against a raised surface face down at an angle of about 45 degrees, with arms below, elbows bent, with hands holding the board with dumbbell in a horizontal orientation with open palms on the lower surface. The user then raises and lowers the platform from the elbows through anywhere from 30 degrees to 90 degrees of rotation, while holding the platform in a generally horizontal orientation.

By way of another example, and without limitation, embodiments of the invention may be used to perform an overhead triceps extension exercise. In these embodiments, a single dumbbell is inserted into a slot of a board of an embodiment of the invention. The user holds the platform with dumbbell in a horizontal orientation above the user’s head with open palms on the lower surface. The arms are first extended upward far above the user’s head, then lowered such that the dumbbell drops behind the user’s neck until the platform nearly touches the user’s head. The platform is then raised far upward again, and then lowered repetitively to exercise the triceps.

By way of another example, and without limitation, embodiments of the invention may be used to perform a row exercise. In these embodiments, a single dumbbell is inserted into a slot of a board of an embodiment of the invention, and a pair of handle extensions are provided on outside left and right edges of the platform. The user leans forward from the waist at an angle of about 45 degrees, with arms below, elbows bent, with hands holding each of the handle extensions. The user then repetitively raises and lowers the platform using elbows and shoulders from around the knees to around the waist.

In other aspects, embodiments of the board of the present invention may be used with other methods of resistance including without limitation, cable machines, resistance bands, kettlebells, and any other heavy object that may be attached to embodiments of a multi-use adapter. Embodiments of a multi-use adapter may comprise a first end or “puck” portion that engages the closed inside end of the dumbbell insertion slot on an embodiment of the board. In some embodiments, a recessed area (which may be circular) may be provided on the upper surface of the board adjacent to the closed end of the slot for receiving an edge of the puck to help hold it in place, and keep it from slipping along the slot. In some embodiments, a looped rope may be suspended from the puck portion of the adapter which hangs below the bottom side of the board when inserted. In these embodiments, the rope end of the adapter may be attached to any of a number of resistance or tension imparting devices, including without limitation, attachment to a cable machine, looped through a kettlebell handle, attached to resistance bands, and the like. A resistance band can be attached to the adapter and used by standing on the looped, middle portion of the resistance band. The loop portion of the adapter hanging below the board provides an attachment point for cable machines, kettlebells, and resistance bands. When such an embodiment is in use, the curl movement is performed in the same manner as done with an inserted dumbbell: the user’s palms and the board remain in a parallel alignment to the floor during the exercise. By way of another example, and without limitation, embodiments of the invention may be used with a cable machine using an embodiment of the multi-use adapter to allow for various muscle exercises. In this example, a board of embodiments of the invention is attached to a cable machine using an embodiment of the multi-use adapter. It is to be appreciated that in this example, the position of the board is inverted, with the loop portion of the adapter extending upward through the slot leading to an engagement with a cable machine. In an exemplary exercise, the user may then perform a triceps pushdown exercise by pressing down on the (inverted) underside of the board with the hands/palms. This pressure is resisted by the tension of the cable machine, which may be set to any desired resistance by the user. The position of the board begins approximately across from the user’s chest, with the user’s arms bent at the elbow, and ends when the board is approximately across from the user’s waist, with the user’s arms extended. The board may then be pulled back up by the cable machine, and the exercise repeated, preferably with the board remaining parallel to the floor. It is to be appreciated that other exercises of other muscles may also be accomplished using similar embodiments of the invention.

By way of yet another example, and without limitation, embodiments of the invention may be used to train back muscles (lats). For such exercises, the set-up position of the board is the same as for the triceps movement described above. The board is inverted and attached to a cable machine using a multi-use adapter. For these exercises, the user maintains straight arms (locked elbows) and sweeps the attached board from a position approximately across form the user’s face, down and towards the user’s waist area. The user then returns to the starting position and repeats the movement.

It is to be appreciated that the above examples are illustrative and non-exclusive, it being understood that numerous other arm, leg, back or other muscle strengthening exercises are also possible using different embodiments of the present invention. It is therefore an object of the present invention to provide methods and apparatus for use in exercising human biceps that target the biceps without significant forearm muscle activation.

It is a further object of the present invention to provide methods and apparatus for use in exercising human muscles other than biceps including without limitation, triceps, other arm muscles, shoulder muscles, back muscles, leg muscles and abdominal muscles.

It is a further object of the present invention to provide methods and apparatus for use in exercising human muscles that are easy to use and simple to construct.

It is a further object of the present invention to provide methods and apparatus for use in exercising human muscles that may be engaged with existing dumbbells.

It is a further object of the present invention to provide methods and apparatus for use in exercising human muscles that may be used in conjunction with existing weight lifting apparatus including without limitation resistance bands, kettlebells, cable machines, springs, a plate or ball, a spherical component, a looped component, or other exercise / resistance devices or heavy objects.

It is a further object of the present invention to provide methods and apparatus for use in exercising human muscles in which the weight, resistance and/or tension imparted using the device may be adjusted by the user.

Additional objects of the invention will be apparent from the detailed descriptions and the claims herein.

DETAILED DESCRIPTION Referring to the drawings wherein like reference characters designate like or corresponding parts throughout the several views, and referring particularly to the exemplary embodiment of Figs. 37-44, it is seen that in this illustrated embodiment, a board or platform generally depicted as 21 is provided having an upper surface 23, a lower surface 25 and a thickness that gives platform 21 sufficient strength to support significant weight or resistance that may be engaged with the platform. The platform has a front side or edge 30, a generally parallel rear side or edge 31. The platform also has a left side or edge 32 and a generally parallel right side or edge 33. The corners of the platform may be optionally rounded to different degrees, as shown in the various illustrated embodiments.

An elongated slot 27 is provided in the platform extending inward from the front edge 30 to approximately the middle of the platform at 28. In the illustrated embodiment of Figs. 37-44, a pair of optional upwardly protruding tabs 38, 39 may be provided on the upper surface 23 of the platform near the front edge 30. An optional recess 24 may be provided on upper surface 23 adjacent to the closed end 28 of slot 27. As shown in the illustrated embodiment of Figs. 75-81 , a latch 51 may be provided at the open end of slot 27. As shown in Figs. 4-9, a dumbbell 41 may be provided having a first weight 43 at one end of a handle or crossbar 44, and a second weight 45 at the opposite end. As shown in Figs. 4-10, the crossbar 44 of a dumbbell may be oriented in a vertical direction and slidably engaged with slot 27 of the platform 21 . As shown in Figs. 4-5, if a recess 24 is provided, it may be shaped in order to receive an inside end of one of the weights 43 or 45 of the dumbbell to help prevent it from sliding out of the slot 27 while the platform 21 is in use. As shown in Fig. 15, if tabs 38 and 39 are provided, they may be shaped in order to engage an outside edge of one of the weights 43 or 45 of the dumbbell to help prevent it from sliding out of the slot 27 while the platform 21 is in use. One or more optional reinforcement rings 26 may be provided around recess 24 to provide support to a dumbbell weight when engaged with the platform. (See, for example, Figs. 17, 37-60, 75-90 and 98-105.) In alternative embodiments, such as the one shown in Figs. 75-82, a latch 51 may be provided along slot 27. The latch may be provided anywhere along slot 27, but usually at or near the open end of the slot at front edge 30. Latch 51 may be spring loaded having a pivotally mounted movable member 53 which may be pushed inward against a wall of slot 27 as the handle or crossbar 44 of a dumbbell slides into slot 27. Once crossbar 44 passes member 53, the spring causes it to extend out across slot 27 to prevent the dumbbell from exiting from the slot while the platform 21 is in use. To disengage, member 53 may be manually pushed against the side wall of slot 27 in order to remove the dumbbell crossbar from the slot. It is to be appreciated that although a spring loaded latch is illustrated, any suitable mechanism(s) may be used to prevent the dumbbell from exiting the slot, including without limitation, a perpendicular slot extending across slot 27 for receiving a removable stop, inwardly facing deformable ridges on the inside edges of slot 27, or other suitable structures.

In alternative embodiments such as the exemplary embodiments shown in Figs. 1 , and 30-36 a pair of openings 46, 47 may be provided on platform 21 to receive the user’s fingers allowing them to extend through the platform. In other embodiments, such as, without limitation, those shown in Figs. 14, 37-67, 75-105, and 113-119 a pair of slots 48, 49 (not openings) may be provided on lower surface 25 allowing the user’s fingers to grip the platform, but not extend through. In some embodiments, such as, without limitation, the embodiments shown in

Figs. 17, 37-60, 75-90, and 98-105, one or more upwardly extending ridges 26 may be provided adjacent to the closed end 28 of slot 27 to engage corresponding structures on a dumbbell.

In some embodiments, such as, without limitation, the embodiments shown in Figs. 45- 60, 75-82, and 98-105, a peripheral ridge 29 may be provided around the upper surface 23 of platform 21. Such a ridge may be used in conjunction with other embodiments having upwardly extending ridges 26 adjacent to closed end 28 of slot 27 in order to provide additional support for a dumbbell or other resistance, as well as to provide reinforcing strength to the overall platform 21. Such a ridge may be used in conjunction with other embodiments having restrictor tabs 38, 39 to provide support. As shown in Figs. 19 and 22, structures other than a dumbbell may be engaged with slot 27.

Embodiments of the present invention relate generally to health and fitness and more specifically to an integrated system that enables a person to perform a biceps training exercise that directly targets the biceps and minimizes activation of the forearm muscles. The invention also affords a user with the ability to utilize a single dumbbell in conjunction with the invention to target both biceps simultaneously. An exercise/resistance band can also be attached to the invention while performing the exercise, which can then be performed with or without an inserted dumbbell.

The type of attachment mechanisms used can consist of but are not limited to eyelet screws, carabiners, holes, rings, or any mechanism capable of attaching each end of an exercise / resistance band 71 to opposite sides of the invention. In alternative embodiments (not shown), the extensions may be provided in the form of outwardly extending handles which may be grasped by a user’s hands while exercising with an embodiment of the invention. Figs. 13A and 13B show two illustrations of a user holding an embodiment of the invention with an inserted dumbbell. Fig. 13A shows the user, holding the embodiment with an inserted dumbbell in a lowered position. The user’s palms (not visible) are placed on the underside of the platform (as shown in Figure 10) and the user’s fingers are shown curled upwards to grasp the invention’s weight control handles 46, 47 (this prevents the invention and the inserted dumbbell from sliding off the user’s palms when held in a lowered position). The dumbbell insertion slot 27 is shown positioned towards the user’s body. An exercise/resistance band 71 is attached to the platform at two connection points 61 , 62. The user is shown holding the center portion of the exercise resistance band underneath the user’s feet to provide an anchor point for the band. Fig. 13B shows the user raising the platform 21 with an inserted dumbbell 41 by providing upward pressure with the user’s palms 76, 77 on the underside 25 of the platform (as shown in Fig. 10). An exercise/resistance band 71 is shown being stretched as the user raises the invention upwards. (The resistance band 71 is attached in the same manner shown in Figure 14A.) This embodiment may also be utilized with an attached resistance/exercise band 71 without an inserted dumbbell 41.

Figs. 14A and 14B show two illustrations of an embodiment of the invention where the weight control handles 48, 49 recessed on the underside surface of the invention but do not penetrate through the top surface of the invention. Fig. 14A shows the top side surface 23 of the embodiment, a dumbbell insertion slot 27, a recessed area 24 at the end of the dumbbell insertion slot 28, and two dumbbell slide restrictors 38, 39. The dumbbell slide restrictors 38, 39 prevent the dumbbell from sliding off the top surface of the invention if the invention is accidentally tilted towards the user (towards the open end of the dumbbell slot) with an inserted dumbbell. Fig. 14B shows the underside 23 of the same embodiment of the invention including two recessed weight control handles 48, 49 and the underside of the invention’s dumbbell insertion slot 27. The process to utilize the dumbbell control handles 48, 49 is similar to the process in the descriptions related to Figs. 10-11. Flowever, in this embodiment, the user’s fingers are prevented from penetrating through the surface plane of the top side surface of the invention 23 but are still able to grip the interior of the recessed handles. Although two different embodiments of weight control handles are described herein (Figures 10, 11 , 14), the use of such a weight control component as a feature of the invention is not limited to the configurations described and may also consist of, but is not limited to: protruding handles, straps, grips of any type, rings, or any method of controlling the invention and preventing it from sliding off of the user’s hands in the lowered position shown in Fig. 11A.

Fig. 15 is an illustration of a side view of an assembled embodiment of the invention with an inserted dumbbell. The embodiment is shown tilted towards the user (open end of dumbbell insertion slot), and two dumbbell slide restrictors 38, 39 are shown preventing the dumbbell from sliding off the top surface 23.

Figs. 16A and 16B show two illustrations. Fig. 16A shows a top surface 23 of an embodiment of the invention having a recessed dumbbell placement area 24 adjacent to the closed end 28 of the dumbbell insertion slot 27. Fig. 16B shows a dumbbell 41 prior to insertion into the dumbbell insertion slot 27 with the dumbbell showing protruding components 42 at the location where the dumbbell’s handle 44 connects to a weighted end 43 of the dumbbell. The recessed dumbbell placement area 24, allows the dumbbell’s protruding components 42 to be placed lower than the main, top surface 23 of the platform 21 thus enabling the inner surface of the dumbbell’s top weighted end 43 to lay flat on the main, top surface 23 of the platform which surrounds the recessed dumbbell placement area 24. Allowing the inner surface of the dumbbell’s top weighted end 43 to lay flat on the top surface 23 while accommodating the dumbbell’s protruding components 42, provides stability and helps to minimize the movement of the inserted dumbbell 41.

Fig. 17A shows a top surface of an embodiment of the invention having both a recessed area 24 and protruding elements 26 at the dumbbell placement area adjacent to the closed end 28 of the dumbbell insertion slot 27. Fig. 17B a dumbbell 41 prior to insertion into the dumbbell insertion slot 27 with the dumbbell showing protruding components 42 where the dumbbell’s handle 44 connects to the weighted portion of the dumbbell. The recessed 24 and protruding 26 dumbbell placement areas allow the dumbbell’s protruding components 42 in the embodiment shown, to be placed lower than the main, top surface of the platform thus enabling the inner surface of the dumbbell’s top weighted end 43 to lay flat on the top surface areas of the protruding components 26 of the dumbbell placement area of the platform. Allowing the inner surface of the dumbbell’s top weighted end 43 to lay flat on the top surface areas of the protruding components 26 while accommodating the dumbbell’s protruding components 42, provides stability and helps to minimize the movement of the inserted dumbbell 41.

Fig. 18 shows two different embodiments of attachment mechanisms that can allow cable machine attachments or resistance bands to be utilized with embodiments of the invention. Fig. 18A shows an embodiment of an attachment device 91 with a flat surface area 95, a dumbbell slot post 93, and an attachment extension 94. Fig. 18B shows a different embodiment of an attachment device 92 with a spherical component 96, a dumbbell slot post 93, and an attachment extension 94. Figs. 19A-D show four different illustrations of embodiments of the invention using two different types of attachment mechanisms. Fig. 19A shows an embodiment of a platform with a flat surfaced attachment mechanism 91. The flat surface 95 of the attachment mechanism is shown lying flat on top of the top surface 23 of the platform. The attachment mechanism’s dumbbell slot post 93 is shown inserted into the invention’s dumbbell insertion slot and the connection point 94 is shown located beneath the invention. This configuration allows the user to attach resistance mechanisms to the attachment mechanism which may include but are not limited to resistance bands, cables attached to weights or weight training machines, and any other attachment to enable resistance when the user raises the invention by using their hands placed on the underside of the invention’s surface. Fig. 19B shows an embodiment of a platform with a flat surfaced attachment mechanism 91. The flat surface 95 the attachment mechanism is shown positioned flat on the underside surface 25 of the platform. The attachment mechanism’s dumbbell slot post 93 is shown inserted into the invention’s dumbbell insertion slot 27 and the connection point 94 is shown located above the platform. This configuration allows the user to attach resistance mechanisms to the attachment mechanism which may include but are not limited to resistance bands, cables attached to weights or weight training machines, and any other attachment to enable resistance when the user pushes down on the top surface of the invention by using their hands placed on the top side of the invention’s surface.

Fig. 19C shows an embodiment of a platform with a spherical attachment mechanism 92. The spherical component 96 of the attachment mechanism is shown positioned on top of the top surface 23 of the platform. The attachment mechanism’s dumbbell slot post 93 is shown inserted into the invention’s dumbbell insertion slot 27 and the connection point 94 is shown located beneath the lower surface 25. This configuration allows the user to attach resistance mechanisms to the attachment mechanism 92 which may include but are not limited to resistance bands, cables attached to weights or weight training machines, and any other attachment to enable resistance when the user raises the platform by using their hands placed on the underside 25 of the platform. Fig. 19D shows an embodiment of the platform with a spherical attachment mechanism 92. The spherical component 96 of the attachment mechanism is shown positioned on the underside 23 surface of a platform. The attachment mechanism’s dumbbell slot post 93 is shown inserted into the invention’s dumbbell insertion slot 27 and the connection point 94 is shown located above the upper surface 23. This configuration allows the user to attach resistance mechanisms to the attachment mechanism which may include but are not limited to resistance bands, cables attached to weights or weight training machines, and any other attachment to enable resistance when the user pushes down on the top surface 23 of the platform by using their hands placed on the top surface 23 of the platform.

Figs. 20A-B shows two different illustrations. Fig. 20A shows an embodiment of a kettlebell exercise weight 81 which includes a handle 82 and a weighted component 83 located below the handle. Fig. 20B shows an embodiment of an attachment mechanism 86 that can be used to engage a kettlebell 81 with a platform of the invention. The embodiment of the illustrated attachment mechanism 86 includes, but is not limited to, a spherical component 87 and a looped component 88 where both ends of the loop are constricted within the spherical component 87. The spherical component 87 can be comprised of, but is not limited to the following material examples: rubber, plastic, metal, wood, or a combination of the aforementioned materials. The looped component 88 can be comprised of, but is not limited to the following material examples: nylon cord rope, metal wire, braided metal wire, metal cable, rope, or a combination of the aforementioned materials.

Figs. 21A-B shows two illustrations. Fig. 21A shows an exemplary process for securing an embodiment of an attachment mechanism 86 to an embodiment of a kettlebell 81. This illustration shows the loop component 88, inserted through the kettlebell’s handle 82, while the spherical component 87 remains on one side of the kettlebell handle 82. The spherical component 87 is then moved over the top of the kettlebell handle 82 and through the end of the loop component 88 which forms a secure “knot” around the kettlebell’s handle 82. Fig. 21 B shows an exemplary embodiment of an attachment mechanism 86 secured to a kettlebell handle 82 using a knot formed by the attachment mechanism’s loop component 88. A kettlebell 81 is shown suspended from the attachment mechanism 86.

Fig. 22 is an illustration an embodiment of a platform of the invention showing the insertion of an attachment mechanism 86 with an attached kettlebell 81 positioned into the invention’s dumbbell insertion slot 27. The spherical component 87 of the attachment mechanism 86 is shown resting on the top surface 23 of the platform. Although a spherical component 87 is shown in this embodiment, the component can be any shape that is larger or configured in such a way to prevent the component 87 from falling through the width of the dumbbell insertion slot 27 (e.g. a flat component such as that shown in Fig. 18A). Additionally, the spherical component 87 (or other embodiment with the aforementioned requirements) must be small enough to pass through the open end of the loop 88 after it has been inserted through a kettlebell handle 82 (See Fig. 21 ). The illustration also shows a kettlebell 81 connected to an attachment mechanism 94, suspended from the platform (if a user’s hands were holding the invention with both palms supporting the invention as shown in Figure 10).

The illustrations of Figs. 23-29 disclose an exemplary embodiment of the invention having a recess 24 on the upper surface 23 adjacent to the closed end 28 of slot 27, and a pair of tabs 38, 39 for holding an edge of a dumbbell in place against surface 23. This exemplary illustrated embodiment also includes a pair of slots 48, 49 on the lower surface 25 which do not extend through the platform.

The illustrations of Figs. 30-36 disclose an exemplary embodiment similar to that disclosed in Figs. 23-29 except that slots 48, 49 extend through platform 21 .

The illustrated embodiments of Figs. 37-44 disclose an exemplary embodiment similar to that disclosed in Figs. 23-29 but also including an upper ridge 26 adjacent to a portion of the closed end 28 of slot 27. This ridge 26 may be used to engage an edge of a dumbbell weight or other resistance structure that is engaged with platform 21. The illustrations of Figs. 45-52 disclose an exemplary embodiment of the invention having a recess 24 on the upper surface 23 adjacent to the closed end 28 of slot 27 which is surrounded by a ridge 26. This exemplary illustrated embodiment also includes a peripheral ridge 29 around upper surface 23 which is raised to create restricting tabs 38, 39 on either side of the opening to slot 27. A pair of slots 48, 49 may be provided on the lower surface 25 which do not extend through the platform.

The illustrations of Figs. 53-60 disclose an exemplary embodiment of the invention similar to that of Figs. 45-52, but having multiple ridges 26 adjacent to the closed end 28 of slot 27, without a central recess on upper surface 23. Instead, the central area adjacent to the closed end 28 is at the same level as the remainder of upper surface 23, but is surrounded by one of the ridges 26 such that it is capable of receiving and holding an edge of a dumbbell or other resistance imparting mechanism. The illustrations of Figs. 61-67 disclose an exemplary embodiment of the invention without a central recess 24, but having resistance tabs 38, 39 for holding an edge of a dumbbell weight or other structure in place on the upper surface 23. A pair of slots 48, 49 may be provided on the lower surface 25 which do not extend through the platform. The illustrations of Figs. 68-74 disclose an exemplary embodiment of the invention having a platform 21 , central slot 27 and closed end 28, without any recess 24, nor tabs 38,38, nor ridges 26 or 29.

The illustrations of Figs. 75-82 disclose an exemplary embodiment of the invention similar to that of Figs. 53-60, but also including an embodiment of a latch for holding a dumbbell handle 44 in place in slot 27. The illustrated latch includes a spring- loaded movable member 53 pivotally mounted at 51 in such a way that member 53 may be moved pivotally inward against an inside wall of slot 27 when a handle 44 is inserted into slot 27, and springs back into the position shown after the handle has passed. Mount 51 is designed to prevent member 53 from pivoting outward out of slot 27, which helps prevent handle 44 from sliding out of slot 27 during use.

The illustrations of Figs. 83-90 disclose an exemplary embodiment of the invention similar to that of Figs. 37-44, but also including an embodiment of a latch similar to that shown in Figs. 75-82.

The illustrations of Figs. 91-97 disclose an exemplary embodiment of the invention similar to that of Figs. 23-29, but also including an embodiment of a latch similar to that shown in Figs. 75-82. The illustrations of Figs. 98-105 disclose an exemplary embodiment of the invention similar to that of Figs. 45-52, but also including an embodiment of a latch similar to that shown in Figs. 75-82.

The illustrations of Figs. 106-112 disclose an exemplary embodiment of the invention similar to that of Figs. 68-74, but also including an embodiment of a latch similar to that shown in Figs. 75-82.

The illustrations of Figs. 61-67 disclose an exemplary embodiment of the invention but also including an embodiment of a latch similar to that shown in Figs. 75- 82.

One example of a way that embodiments of the invention may be used calls for orienting a platform 21 of an embodiment of the invention in a horizontal position. A dumbbell 41 having a crossbar 44 is oriented in a vertical direction. The dumbbell itself has a weight that is known to the user, and additional weights 43, 45 may be provided at opposite ends of crossbar 44, as desired by the user. Crossbar 44 is inserted through the front opening of slot 27 and pushed all the way to the closed end 28 of the slot. One of the weights (e.g., 43) will then be located above platform 21 , and the other weight (e.g. 45) will be hanging below the platform. Once the crossbar is engaged with the slot, this causes the weight 43 above the platform to come into contact with the upper surface 23 of the platform, while the crossbar extends downward from the platform to the other weight 45 at the opposite end. This causes the platform 21 to support the heavy weight of the entire dumbbell and crossbar. It is to be appreciated that the amount of weight supported by the platform may be selected and adjusted by the user according to the weight of the dumbbell, and/or how much weight, if any, is placed on the dumbbell.

In some embodiments, a recess 24 may be provided on the upper surface 23 of the platform adjacent to the closed end 28, which may receive an inside end of the uppermost weight 43 to prevent it from sliding in slot 27 as the platform is used for exercises.

In some embodiments, one or more upwardly protruding tabs 38, 39 may be provided on the upper surface 23 of the platform on opposite sides of the slot 27. These tabs may engage edges of the uppermost weight 43 to prevent it from sliding out of slot 27 as the platform is used for exercises. In some embodiments, a movable latch may be provided at the front opening of slot 27. In some of these embodiments, the latch may include a spring-loaded movable member 53 that extends across slot 27. One end of member 53 is pivotally attached to a pivot 51 . As crossbar 44 is inserted into slot 27, it passes member 53, pushing it inward against a wall of slot 27 as it pivots. Once crossbar 44 passes movable member 53, the spring causes it to extend back out across slot 27 to prevent crossbar 44 and dumbbell 41 from exiting from the slot while the platform 21 is in use. To remove the dumbbell, member 53 may be manually pushed against the side wall of slot 27, allowing the crossbar 44 to slide out of slot 27. It is to be appreciated that although a spring-loaded latch is illustrated, any suitable mechanism(s) may be used to prevent the dumbbell from exiting the slot, including without limitation, a perpendicular slot extending across slot 27 for receiving a removable stop, inwardly facing deformable ridges on the inside edges of slot 27, or other suitable structures.

Once a dumbbell 41 with crossbar 44 and weights 43, 45 is engaged with the platform 21 , it is ready to be used for exercises. In one exemplary exercise, the user may place the palms of both hands on the lower surface 25 of the horizontally oriented platform 21 with palms facing up (underneath the platform) on either side of the slot 27. It is to be appreciated that since no gripping is necessary, the fingers and forearms are not implicated by this positioning. Supporting the platform in this way will transfer tension to the user’s biceps, allowing the biceps to be exercised by raising and lowering the weighted platform, without significantly affecting the user’s forearms. It is to be appreciated that other means of providing resistance other than a dumbbell may be used, and that muscles other than the biceps may be exercised using embodiments of the invention. In order to perform a bicep curl exercise using an embodiment of the above example, an inserted dumbbell 41 is suspended by the horizontally oriented platform 21 with the user’s palms (facing up) supporting the platform, so that the platform is in a position that is generally parallel to the floor. The user has the option of placing the hands at varied widths apart on the underside 25 of the platform. The palms should remain in a position parallel to the floor while holding the platform. The initial top position of the platform may be approximately across from the user’s shoulders. As the user lowers the platform, the user should maintain the platform in a parallel position to the floor as much as possible, lowering the platform until it is approximately across from the user’s waist. At this bottom position of the movement, the user should still maintain the platform in a parallel position to the floor. The user then repeats the movement by returning to the top position of the movement (across from the shoulders), always with an emphasis on keeping the platform parallel to the floor during the exercise. It is to be noted that in the top position, the user’s hands are flat on the bottom side of the platform and the wrists are bent forward away from the user’s body.

An embodiment of the above example may also be used to perform front deltoid shoulder raises. For this exercise, the user may start in the same position used to perform a curl exercise described above with a single vertically-oriented dumbbell 41 inserted into a slot 27 of a horizontally oriented platform 21 of an embodiment of the invention. However, instead of performing a curl movement, the user keeps their arms straight (elbows locked) with the platform starting at a position approximately across from the user’s waist, or slightly lower. The user then raises the platform outwards and upwards in front of their body until it is approximately across from the shoulders. The user then lowers the platform and inserted dumbbell in the same manner and repeats the movement for multiple repetitions, preferably while maintaining the board platform parallel to the floor as much as possible. In other examples, instead of inserting a dumbbell into slot 27, an adapter may be used. In these examples, the adapter has a wide upper component or “puck” attached to a slot post which leads to an attachment device. The upper component may be flat 95, spherical 96, or of some other shape that is wider than slot 27. The upper component is attached to a post 93 that fits through slot 27 in the same way as a dumbbell crossbar 44. Slot post 93 is attached to an attachment mechanism 94 such as a loop or rope, which may then be engaged with another resistance imparting device such as without limitation, a cable machine, resistance band, kettlebell, and another heavy object.

In some embodiments, a recessed area 24 (which may or may not be circular) may be provided on the upper surface 23 of the platform 21 adjacent to the closed end 28 of the slot 27 for receiving an edge of the puck to help hold it in place, and keep it from slipping along the slot.

In some embodiments, a looped rope 94 may be suspended from the puck portion of the adapter which hangs below the bottom side 25 of the platform when inserted. In one example, a resistance band may be attached to the rope and used by the user standing on the looped, middle portion of the resistance band. The loop portion 94 of the adapter hanging below the platform provides an attachment point for cable machines, kettlebells, and resistance bands. When such an embodiment is in use, the curl movement is performed in the same manner as done with an inserted dumbbell: the user’s palms and the board remain in a parallel alignment to the floor during the exercise.

By way of another example, and without limitation, embodiments of the invention may be used with a cable machine using an embodiment of the multi-use adapter to allow for various muscle exercises. In this example, a platform 21 of embodiments of the invention is attached to a cable machine using an embodiment of the multi-use adapter. It is to be appreciated that in this example, the position of the platform is inverted, with the loop portion 94 of the adapter extending upward through the slot 27 leading to an overhead engagement with a cable machine. In an exemplary exercise, the user may then perform a triceps pushdown exercise by pressing down on the (inverted) underside 25 of the platform with the hands/palms. This pressure is resisted by the tension of the cable machine, which may be set to any desired resistance by the user. The position of the platform begins approximately across from the user’s chest, with the user’s arms bent at the elbow, and ends when the platform is approximately across from the user’s waist, with the user’s arms extended. The platform may then be pulled back up by the cable machine, and the exercise repeated, preferably with the platform remaining parallel to the floor. It is to be appreciated that other exercises of other muscles may also be accomplished using similar embodiments of the invention. By way of yet another example, and without limitation, embodiments of the invention may be used to train back muscles (lats). For such exercises, the set-up position of the platform 21 is the same as for the triceps movement described above. The platform is inverted and attached to a cable machine using a multi-use adapter. For these exercises, the user maintains straight arms (locked elbows) and sweeps the attached platform from a position approximately across form the user’s face, down and towards the user’s waist area. The user then returns to the starting position and repeats the movement.

It is to be appreciated that the above examples are illustrative and non-exclusive, it being understood that numerous other arm or leg strengthening exercises are also possible using different embodiments of the present invention.
