CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims priority to U.S. Provisional Application, Ser. No. 62/688,638, filed Jun. 22, 2018, entitled “Auto-Adjustable Dumbbell, System, and Method,” the entire contents of which is hereby incorporated by reference in its entirety herein. 
    
    
     FIELD 
     The present inventions relate to the field of physical fitness equipment. The present inventions more specifically relate to the field of weight lifting equipment and exercise programs. 
     BACKGROUND 
     Handheld weights, such as dumbbells are well known. Such weights have been used for fitness dating back to ancient Greece. Functional trainers are also well known. Today these weight devices are some of the most popular strength and fitness tools, and are seen in virtually every gym and weight room. In addition, one or both of these types of weight devices are also used at home. 
     While both types are weights are versatile, they are significantly underutilized. For example, dumbbells and functional trainers can be used for a number of exercises, but it is an “art” to actually use the weights properly. In addition, during exercise, an individual user must select the weight, thereby requiring the user to select the correct weight and focus on constantly changing weight if the device is used during the during a physical fitness training routine. 
     Accordingly, a need exists for a weight device, system and method which address the various drawbacks of existing devices. In particular, a need exists for a weight device, system, and method that leverage the functionality or take advantage of the potential and versatility of the weight device during exercise or physical fitness routine and further let the user focus on exercise rather than changing weight. 
     SUMMARY 
     Accordingly, an auto-adjustable weight device, system, and method are disclosed which solve one or more drawbacks of existing devices. In particular, a weight device, system, and method are disclosed that leverage the functionality or take advantage of the potential and versatility of the weight device during exercise or physical fitness routine and further let the user focus on exercise rather than changing weight. As disclosed in greater detail below, an auto-adjustable weight device is provided that is combined with a software application executed by a portable electronic device. 
     More specifically, an auto-adjustable weight device is disclosed that comprises a weight retainer comprising one or more receptors; one or more weight rods sized to be received in the one or more receptors; and a selector mechanism configured to select one or more weight rods and secure the weight rods in the weight retainer receptors in response to an instruction from a software application. 
     An auto-adjustable weight system is also disclosed. The auto-adjustable weight system includes a weight device having a weight retainer which receives one or more weight rods, the weight rods being selectively and removably retained within the weight retainer. A platform receives the weight device and carries one or more weight rods not selected and retained within the weight retainer. A software application in communication with the platform or weight device is configured to drive selection and retention of the number of weight rods retained within the weight retainer. 
     A physical training system is also disclosed. The system includes a weight device having a weight retainer which receives one or more weight rods. The weight rods are selectively and removably retained within the weight retainer. A platform receives the weight device and carries one or more weight rods not selected and retained within the weight retainer. A software application is provided in communication with the platform or weight device and configured to drive selection and retention of the number of weight rods retained within the weight retainer. A database of selectable workout segments is also provided, wherein the software application selects and executes a selectable workout segment from the database of selectable workout segments simultaneously with the selection of one or more weight rods which are retained by the weight device. 
     The weight device disclosed herein provides an improved fitness experience by automatically adjusting the amount of weight throughout the workout, but also allows a user to manually adjust the amount of weight. It does this through the use of an integrated phone app and an engageable platform which holds one or more weight rods. To use the system, the user first enters basic information into the app (age, weight, gender, fitness ability, fitness goals), then prior to a workout the user selects the difficulty, length, and type of workout. Once the workout begins, the app adjusts the amount of weight for each specific exercise based on the user preferences. Or, users can adjust the weights with a touch of a button, such as on the smartphone or tablet. 
     These and other features and advantages of devices, systems, and methods according to this invention are described in, or are apparent from, the following detailed descriptions of various examples of embodiments.

It should be understood, of course, that the invention is not necessarily limited to the particular embodiments illustrated herein. 
     DETAILED DESCRIPTION 
     Referring generally to the Figures, an auto-adjustable weight device, system, and method are disclosed. A weight device, system, and method are disclosed that leverage the functionality or take advantage of the potential and versatility of the weight device during exercise or physical fitness routine and further let the user focus on exercise rather than changing weight. As disclosed in greater detail below, an auto-adjustable weight device is provided that is combined with a software application executed by a portable electronic device. In addition unlike existing “selectorized” dumbbells and functional trainers, there are no knobs to turn or pins to adjust on the novel weight device disclosed herein. The weight adjustment may happen through the integrated app, and mechanism discussed below. Strength training of any type requires a higher degree of understanding than cardio workouts. For strength training, many if not most users don&#39;t understand which movements are helpful vs. which can lead to injury. Also, knowing how hard to push and how to arrange the different exercises is not clear to many users. In contrast, the weight system disclosed herein can figure everything out for the user: pace, difficulty, weight, length, type of workout. This can make the workout more engaging. The app also allows people to connect from home; either with an instructor at the gym, or a group of users, all connected from their homes, or with a physical trainer or physical therapist. By making the fitness experience easier to figure out, and more connected to a fitness community, the user is more likely to stay engaged. These and other features and advantages of devices, systems, and methods according to this invention may be described in, or are apparent from, the following description. 
     In particular, an exercise or physical fitness system is disclosed which includes an auto-adjustable weight device with an integrated software application, and customizable video workouts shown in a smartphone or other portable electronic device screen. More specifically, the auto-adjustable weight system includes a weight device as described and a platform carrying one or more weight rods and which interacts with said weight device. In one or more examples of embodiments, the software application automatically adjusts the weights so as to change the amount of weight for each exercise. Alternatively, a user may “manually” adjust the weights via a touch of a button on the smart device screen. Advantageously, there are no buttons or knobs on the weight device(s) itself. 
     In one or more examples of embodiments, as shown in  FIGS. 1-5 , the system consists of one or more, and in the illustrated examples two weight devices  100  (illustrated as dumbbells in several of the Figures), a platform  102  for support of and interaction with the weight device(s)  100 , and an app or software application driven by an electronic device or portable electronic device  104  to operate the adjustment of the weight device(s)  100 . It is noted that dumbbells are disclosed for purposes of illustration and example only, and one of skill in the art will appreciate that the principles of the invention can be adapted to a number of different weight or exercise devices. Furthermore, while two weight devices  100  are described and shown in various embodiments, it is contemplated that less than or more than two weight devices  100  may be used with the system described herein. Likewise, while a software application executed on a portable electronic device  104  is specifically described to operate the adjustment of the weight device(s)  100 , the adjustment and operation may be done without a software application or portable electronic device  104 . 
     Referring to  FIGS. 8-17, 26 , each weight device  100  is provided with a weight retainer  106  that either retains or disengages one or more, or a series of weight rods  108 . In one example, the weight rods  108  are composed of metal but one of skill in the art will appreciate that any number of materials or combinations of materials may be used for a weight rod. The weight rods  108  may be made from any suitable weighted material, examples of which include steel or cast iron. For instance, in one example of embodiments steel rods may be used; alternatives, however, could include sheet metal plates or a heavier casing made from cast metal, and the like. One of skill in the art would appreciate that alternative materials or combinations of materials accomplishing the same purposes may be substituted for those noted herein. 
     Any range of shapes may be used for the weight rods  108 ; e.g., they could be any geometric configuration, including but not limited to, rectangular steel plates, hexagon rods, or cylindrical rods as shown, and combinations of the foregoing (see, e.g.,  FIGS. 7( a )-( d ) ). In other words, a “rod” is not necessary for achieving the purposes provided, but instead a weight member may be provided having a specific poundage may be used with a correspondingly shaped retainer, and retained by the same or a similar rotating tab. The number of pounds of each weight rod may also vary. For example, a series of 1 pound (lb) weights  108   a  and 3 lb weights  108   b  housed within each weight retainer  106  may be provided. This particular arrangement enables the user to adjust the amount of weight in 2 lb increments. The same overall design could instead support adjusting in 1 lb, 2.5 lb, or other increments if the weight modules or rods  108  were adjusted accordingly. It is understood that any number of pounds per weight rod  108  may be suitable for the purposes provided. Likewise, while weights are described in pounds, metric units and increments are also acceptable. Of course, the weight retainers  106  may also be used without any weight rods. 
     In one or more examples of embodiments, The weight retainers  106  may be a weight casing and can be made from injection-molded structural plastic (such as glass-filled nylon), cast or extruded aluminum, or cast steel. In the attached illustrations, the weight retainers  106  are made from a combination of structural plastic and extruded aluminum. The weight retainers  106  retain one or more, and in preferred examples of embodiments, a series of weight rods  108  combined in any number of combinations to achieve a desired total weight. In this regard, while a weight casing is illustrated in the Figures, a weight retainer may also be a skeletal structure in which weight rods are retained, but not enclosed, or partially enclosed. Each weight retainer  106  is composed of one or more receptors  110  and in the illustrated examples a plurality of receptors which are configured to mate with the weight rods  108  and receive them within the retainer. In this regard, various shape and/or sized weight receptors  110  (e.g.,  110   a ,  110   b ) may be provided with sizes that correspond in size and position to the corresponding weight rod  108   a  or  108   b . In the examples provided, the receptors  110  have a depth such that the weight rods  108  are retained entirely within the retainer  106 , although such a configuration is not required as one of skill in the art could conceive of a configuration which engages and grips only a portion of a weight rod. 
     As shown in  FIGS. 8-17 , the weight rods  108  are retained in designated locations on a platform  102 . These locations are aligned with corresponding receptor  110  positions in the weight retainer  106 . The weight device  100  rests on the platform  102 , such that the weight retainers  106  are positioned over the weight rods  108 , which are received within the weight retainers  106 . 
     Various weight rod  108  arrangements may be used. In the illustrated embodiments, nine different arrangements, from 4 lb to 20 lb are shown for purposes of example. In  FIG. 8 , an arrangement is shown in which no weights are provided in the weight retainer  106 . This “base weight,” in which no weight rods or removable weight rods  108  are provided in the weight device  100  or weight retainer(s)  106 , may be calibrated to be the minimum weight of the weight device  100 . For example, the minimum weight may be 4 lb. When in this configuration, all of the weight rods  108  remain on the platform  102 . In  FIG. 9 , an arrangement of 2×1 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIG. 8 . For example, the particular arrangement may be 6 lb. When in this configuration, one or more weight rods  108 —in this case 2, 1 lb weight rods  108   a —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 10 , an arrangement of 4×1 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-9 . For example, the particular arrangement may be 8 lb. When in this configuration, one or more weight rods  108 —in this case 4, 1 lb. weight rods  108   a —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 11 , an arrangement of 2×3 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-10 . For example, the particular arrangement may be 10 lb. When in this configuration, one or more weight rods  108 —in this case 2, 3 lb weight rods  108   b —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 12 , an arrangement of 2×3 lb+2×1 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-11 . For example, the particular arrangement may be 12 lb. When in this configuration, one or more weight rods  108 —in this case 2, 3 lb weight rods  108   b , plus 2, 1 lb weight rods  108   a —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 13 , an arrangement of 2×3 lb+4×1 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-12 . For example, the particular arrangement may be 14 lb. When in this configuration, one or more weight rods  108 —in this case 2, 3 lb weight rods  108   b , plus 4, 1 lb weight rods  108   a —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 14 , an arrangement of 4×3 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-13 . For example, the particular arrangement may be 16 lb. When in this configuration, one or more weight rods  108 —in this case 4, 3 lb weight rods  108   b —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 15 , an arrangement of 4×3 lb+2×1 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-14 . For example, the particular arrangement may be 18 lb. When in this configuration, one or more weight rods  108 —in this case 4, 3 lb weight rods  108   b , plus 2, 1 lb weight rods  108   a —are retained in the weight device  100 , and a remainder of the weight rods  108  remains on the platform  102 . In  FIG. 16 , an arrangement of 4×3 lb+4×1 lb weights is shown to achieve a desired total weight (including the weight device  100 —base weight) which is different from that shown in  FIGS. 8-15 . For example, the particular arrangement may be 20 lb. When in this configuration, one or more weight rods  108 —in this case 4, 3 lb weight rods  108   b , plus 4, 1 lb weight rods  108   a —are retained in the weight device  100 , and no weight rods remain on the platform  102 . 
     Similar arrangements and configurations can be combined in a similar manner to achieve different base and ending weights, by varying the base weight (e.g., the weight of the device  100  or retainer  106  without any weight rods may be 6 lb vs. 4 lb), and varying the number of available weight rods  108  which may be engaged by the weight device  100 . Compare examples of such varying arrangements and configurations shown in  FIGS. 8, 17, 26  for purposes of illustration. 
     The same overall design could support a different range of minimum and maximum weights. For example, there could be a 3 lb to 15 lb weight device, a 5 lb to  501   b  weight device, an 8 lb to 80 lb weight device, and so forth. The minimum weight or base weight is determined by the weight of the of the weight device  100  unit (i.e., handle  118  plus weight retainers  106 ) without any weight rods retained in the retainers. In some examples of embodiments, to round out the weight of the “empty” weight devices  100 , extra inner rod weights (not shown) may be permanently attached inside the weight retainers  106 . 
     Weight rods  108  can be retained on a platform  102  in a variety of ways. In one example of embodiments shown in  FIGS. 8-17 , and specifically in reference to  FIG. 18 , the weight rods  108  are retained by a pin  112 —which may extend vertically from the upper surface of the platform  102 —protruding into the center of a weight rod. Consequently, a weight rod may have a pin receptor  113  in a bottom surface thereof for receipt of the pin  112  (see  FIGS. 22-25 ). In an alternative embodiment, weight rods  108  may be supported by one or more spaced apart upwardly extending tabs  114 , shown as vertical tabs in  FIG. 19 , positioned around the perimeter of the weight rod, or a plurality of weight rods  108 . 
     In some examples of embodiments, the platform  102  may be oriented as shown in  FIG. 1 , in which a plurality of weight devices  100  are positioned at an angle from one another. In another example, the platform  102  may be positioned such that a plurality of weight devices  100  are positioned so as to be oriented side-by-side ( FIG. 20 ). 
     In certain embodiments comprising a dumbbell or like device, each dumbbell consists of a generally cylindrical handle  118  with weight retainers  106  attached to each end. The handle  118  can be made from a variety of durable materials, such as for example steel rod. 
     In one or more examples of embodiments, the weight configuration may be asymmetrical relative to the centerline “a” (see  FIG. 21 ). However, due to the specific configuration of weight rods  108  in the retainer, the center of gravity of the weight device  100  remains in the center of the handle  118 . As a result, if the user is holding the handle  118  in the middle, the weight device  100  will remain balanced. Likewise, even if the user were to hold the handle  118  off-centered, the asymmetry of the load would be so small that any torqueing of the handle  118  would be imperceptible. 
     In use, a desired weight is selected (either by the user or the software application) which, as will be further discussed herein, then either releases or engages one or more weight rods  108  which, in total, equal the selected weight. The weight rods  108  may be retained and released from the weight retainer  106  in a number of different ways. In various examples of embodiments, selection of a desired weight causes the rotation of one or more of the rotating disks  116 , the rotation of which either releases or engages one or more weight rods  108  which, in total, equal the selected weight. In some examples, small electric motors  120  within the weight device platform  102  drive engagement with the weight rods  108 . More specifically, in some examples of embodiments, a tab  122  which rotates about a vertical axis is shown. In this example, the tab  122  has four positions: Position  1  (open, holding no weight rods), Position  2  (holding one weight rod  108 ), Position  3  (holding two weight rods  108 ), and Position  4  (holding one weight rod  108 ) as shown in  FIGS. 22-25 . With each position, the tab  122  is rotated by 90 degrees. However, variations thereon may be acceptable for accomplishing the purposes provided. While specific examples are described hereinabove, alternatives may also be acceptable. For example, the retention system of rotating tabs  122  described herein can accommodate a variety of ways to cluster the weight rods  108 . For instance, two 1 lb weights  108   a  can be positioned between two 3 lb weights  108   b , retained by two rotating tabs  122 —also achieving a flatter enclosure (see  FIG. 26 ). 
     As shown in  FIGS. 22-25  and referenced above, a series of rotating tabs  122  are provided for retention of weight rods  108  in the weight device retainer. The rotating tabs  122  may be attached to the bottom of the weight retainer  106  and are configured to either retain or disengage the weight rods  108 . The rotating tabs  122  in the illustrated embodiments are sized to engage at least one, and preferably two weight rods  108 . In one or more specific examples of embodiments, the rotating tabs  122  may move through the four described positions, each rotated in 90 degree increments. As can be seen, in  FIG. 22 , the rotating tab  122  is provided in the “open” position, or a first position, wherein the tab  122  is rotated to a position which does not contact or engage any weight rod(s). In  FIG. 23 , the rotating tab  122  is shown in a second position, which may be 90 degrees from the first position. In the second position, the rotating tab  122  engages one weight rod to retain the weight rod in the retainer. In  FIG. 24 , the rotating tab  122  is shown in a third position, which may be 90 degrees from the second position (and 180 degrees from the first position). In the third position, the rotating tab  122  engages two weight rods  108  to retain said rods in position in the weight retainer  106 . In  FIG. 25 , the rotating tab  122  is shown in a fourth position, which may be 90 degrees from the third position. In the fourth position, the rotating tab  122  engages one weight rod (which weight rod is different from that engaged in the second position) to retain the weight rod in position in the weight retainer  106 . While a rotating tab  122  and rotation degree is described, it is understood that variations may be made to retain the weights in other manners without departing from the overall scope of the present invention. 
     One or more rotating tabs  122  may be provided on each weight device  100 , and may have in some examples, at least two spaced apart rotating tabs  122  on each retainer portion of the weight device  100 . 
     The orientation or position of the rotating tabs  122  may be set by a mating rotating disk  116  attached to the weight platform  102  (see  FIG. 18 ). Accordingly, on the top face of the platform  102  may be several rotating disks  116 , aligned under each of the rotating tabs  122  on the weight device  100 . In one or more examples of embodiments, the rotating disk  116  is coupled to and driven by a motor  120 , such as an electric motor (see  FIG. 28 ). A small electric motor  120  coupled to the rotating disk  116  and driven by electronics is provided within the weight platform  102 . Activation of the motor  120  causes rotation of the rotating disk  116 . Each electric motor  120  may drive one, two, or more rotating disks  116  via a gear or belt-drive linkage. In this regard, electronics rotate the tabs  122  via mechanisms located in the platform  102 . While the mechanism to rotate the tab  122  may reside in the platform  102 , it is contemplated that the mechanism for rotation of tabs  122  may be located in the weight device  100  or weight retainer  106 . 
     The rotating disk  116  has a shape that mates with the rotating tab  122  so as to engage and drive rotation of the rotating tab  122  upon activation by the motor  120  and rotation of the disk. In one example, each rotating disk  116  may have a small protrusion  124  on the top face, which aligns with a similarly, matingly shaped depression  126  in the rotating tab  122  when the weight device  100  rests on the platform  102 , providing alignment and the ability to drive the rotation of the rotating tab  122 . 
     Preferably, the adjustment or interchange of weight rods  108  within the retainer  106  can only take place when the weight device(s)  100  are resting on the platform  102 . And more specifically, adjustment or interchange of weight rods  108  preferably occurs upon activation of the motor  120  or rotating disk  116 , which is activated by a control, such as a software application driven by a computing device  104 . In one or more examples of embodiments, to prevent the rotating tab  122  from inadvertently rotating during the use (e.g., the workout or movement of the weight device  100 ), one or more mating ridges  128  and grooves  130  may be provided on the weight retainer bottom  132  and screw head collar  134 , respectively (see  FIG. 29-30 ). In one example, the ridges  128  and grooves  130  are oriented in 90 degree quadrants. A compression washer  136  may be provided to assist in pressing the screw head collar  134  against the ridges  128  on the weight retainer bottom  132 . Orientation of the ridges  128  and grooves  130  is such that the harder the weight rod(s)  108  press against the rotating tabs  122  (e.g., downward), the less the tabs  122  are able to rotate because the ridge  128  and groove  130  are pressed together with greater force. In this example of embodiments, when the weight device  100  is returned to the platform  102  and the motor  120  activates the rotation of the rotating tab  122 , it must lift up the weight rods  108  slightly to overcome the height of the ridge  128 . Varying degrees of “ridge”  128  may be provided. For example a higher ridge  128  and/or a steeper ramp angle may be used to make it more difficult to turn the rotating tab  122 , also requiring the motor  120  to have more torque. 
     While specific examples are described above, there are many alternative options to accomplish the securement of the weight rod(s)  108  in the retainer  106 . In one example, a compression washer may be used in the attachment of the rotating tab  122  to the weight retainer  106 , which creates enough friction resistance to keep it from rotating when the weight device  100  is in use. Another alternative is to add detents to the interface between the rotating tab  122  and the weight retainer  106 , which would register the tab  122  into the four orientations. Alternative mechanical solutions for retaining the weight rods  108  include orienting a tab  122  in the weight device  100  such that the rotating axis is horizontal instead of vertical, and the tab  122  flips inward towards the center of the weight rod. In some examples the tab  122  could be spring-loaded in the closed position, and the platform  102  enclosure could have a vertical plunger under each tab  122  to push it open. An additional alternative option is to have the weight rods  108  retained via leaf springs, situated vertically in the weight retainer  106 , pressing inward toward the center of the weight rod, and having a catch on the end to engage with the edge of the weight rod. When placed back on the platform  102 , the leaf spring may be released by pressing it away from the weight and held by a “catch” within the weight retainer  106 . Another option is to use magnetically attractive material (e.g., steel) for the weight rods  108  and corresponding magnets, such as electrically activated magnets, located in the weight retainer  106  to retain the weight rods  108  in the weight retainer  106 . As indicated, there are a broad range of options for retaining the weight rods  108  in the retainer. The examples provided herein are non-limiting illustrations of possible variations and one of skill in the art may arrive at additional and different mechanisms for accomplishing the same result. 
     Accordingly, once the rotating tab  122  is set to position by the rotating disk  116 , it preferably stays in place (does not rotate any further) after the weight device  100  is picked up so as to retain the weight rod  108 . 
     There are a broad range of options for engaging the rotating tabs  122  or motors  120  to adjust or change the weight of the weight devices  100 . In one example, a handheld device or other computing device  104  communicates with the electronics inside the platform  102 , either wirelessly (via, for example, Bluetooth or Wi-Fi), or via a hard-wired or tethered connection (see  FIG. 1 ). 
     Optionally, the weight device  100  and system may include a base stand  138 , which supports the platform  102 , positioning it at an elevated height for easy access. Referring to  FIGS. 1-5 , one or more systems are shown including a base stand  138 . The base stand  138  includes a base tube  140 , which can be made from extruded aluminum, or steel tube, and a ground engagement  142  which may comprise, for example, one or more base legs or a base plate which could be made from thick steel plate, cast aluminum, iron or steel, or injection-molded structural plastic. The base stand  138  may accommodate casters or wheels  144 , which, among other benefits, allow the system to be rolled into position in a room for a workout, and rolled back away when not in use. In certain examples, the base stand  138  may be fixed in height. The base stand  138  may also include a mechanism making it height adjustable, by for example including a gas cylinder, or a telescoping tube and locking pin. A variety of platform base configurations are also contemplated, including but not limited to a flat plate with feet or bumpers or alternatively a plastic molded structure having casters or wheels. A portable electronic device support  146  is provided on or near the platform  102  may be positioned in a variety of locations. As shown in  FIGS. 1-5 , the device support  146  is provided in front of the weight devices  100 . In  FIG. 20 , the support  146  is positioned behind and/or above the weight devices  100 . In some example of embodiments, such as shown in  FIGS. 31-32 , the platform  102  may be mounted to a wall (e.g., without base stand  138 ) and to this end, the platform  102  may include a wall support  148  which is attached to the wall. The platform  102  may then be attached and secured to the wall support  148 . The platform  102  may also be arranged to be supported on a flat surface, such as a desk or table ( FIG. 33 ). 
     The portable electronic device stand or support  146  is shown in a fixed position, however this also could be height-adjustable, as well as angle-adjustable. In some examples, a portable electronic device support  146  may also be provided on the base stand  138 , positioning it for easy viewing and access (such as pressing buttons). In this regard, in some examples of embodiments, an integrated stand and portable electronic device support may be used to improve the user experience by positioning the weight device  100  at an easy to reach height, and the display at an easy to view angle. 
     In one or more examples of embodiments, wherein the weight device  100  comprises a dumbbell, the dumbbell may uniquely have a constrained small size. In this regard, the size of the dumbbell is determined by the length of the handle and the width of each weight retainer  106 . As the weight retainers  106  uniquely stack or arrange the various weight rods  108  of different sizes (see Figures) to maximize the available space, the weight retainers  106  are narrow in width, yet can accommodate various weights. In comparison, traditional adjustable weight dumbbells have weights attached laterally, increasing in length with successive weights. Advantageously, the dumbbells described herein are compact for storage. Moreover, a user does not inadvertently injure him or herself by scraping a lengthy dumbbell across a leg. As is known, rods on many existing dumbbells, especially selectorized dumbbells, are so long that a user cannot hold the dumbbell naturally for exercises such as curls. The dumbbells are not ergonomic and a user cannot let the weights hang by the user&#39;s side. In comparison, the weight devices disclosed herein can rest more naturally at the user&#39;s sides at the beginning and end of each rep. 
     Various weight devices  100  and fitness devices are contemplated by the system described herein. Many of the figures illustrate a “dumbbell” by way of example; however, a number of weight devices or fitness devices may be substituted in place of such a device. The auto-adjustable weight system could be applied to a variety weight-based fitness products, including but not limited to, dumbbells, kettlebells, barbells, weight vests, functional trainers, “Universal”-style weight stacks, and the like. 
     For example, a functional trainer is shown in  FIGS. 34-39  as a weight device  100 . The functional trainer may use the same weight retention mechanism as the weight device(s)  100  described herein, using weight rods  108 , rotating tabs  122 , electric motors  120 , platform  102  or base, and the like, wherein the electric motors  120  may be driven by a software application executed on a portable electronic device  104 . In this regard, pulling on a handle  150  of the functional trainer would cause the weight cartridge or retainer  106  with selected and retained weight rods  108  to travel vertically upwards in the functional trainer. As shown, the weight rods  108  are contained in the weight cartridge or retainer  106  which is pulled upwards from the base platform  102  as the functional trainer is used. The weight cartridge or retainer  106  passes through two fixed rods  152 , which extend from the top cap  154 , down to the base enclosure or platform  102 . The weight cartridge or retainer  106  is pulled upwards by a central cable  156  in the illustrated example. As can be seen, the rotating tabs  122  are rotated so as to retain one or more weight rods  108 . Vertical pins  112  are also mounted to the base platform  102  to help align the rods  108  when they are lowered, and hold them in place when resting upon the base platform  102 . Inside the base platform may be the motors  120 , printed circuit board  123 , and power supply (such as a battery)  125  ( FIG. 28 ). It is also contemplated that one or more position sensors (not shown) may be used to detect the placement or removal of the weight device  100  and/or a weight rod  108 . 
     As indicated, there are a broad range of options for engaging the rotating tabs  122  or motors  120  for adjusting the weight of the weight devices  100 . In one example, a handheld device or other computing device communicates with the electronics, e.g., the printed circuit board  123 , inside the platform  102 , either wirelessly (via, for example, Bluetooth or Wi-Fi), or via a hard-wired or tethered connection. Unlike existing “selectorized” dumbbells, there are no knobs to turn or pins to adjust on the weight device disclosed herein. The weight adjustment may happen through an integrated software application (“app”), in combination with the mechanism discussed above. A user may use the app to select the amount of weight for each dumbbell. The app then communicates with the electronics in the platform  102  to execute the instructions and make the adjustment of weight in the weight device  100 , via the mechanism described above. Alternatively, after setting up the app (entering basic data such as age, weight, fitness level and fitness goals), the user may rely on the app to decide what is the best amount of weight for each exercise. 
     In one or more examples of embodiments, a seamless integration of the application software driven by a portable electronic device  104 , and the weight device  100 /platform  102  is provided. In some examples of embodiments, the app and its various functions may be provided locally on the portable electronic device  104 . However, in one particular example, the app may be optionally cloud-based or in communication with the cloud so as to deliver feedback data to a third party. For example, the app may deliver feedback data regarding use to a trainer or physical therapist. However, it is also contemplated a workout may stream to a portable electronic device, such as a smartphone or tablet or other screen, which guides the user through use of the weight devices  100  for the workout. 
     A flow chart showing operation of one or more examples of embodiments of the system described herein is shown in  FIG. 40 . As can be seen the software application which is operating on a portable electronic device may receive a variety of data and information and from one or more of a variety of sources, including, but not limited to: user configuration input, a workout database, user history, and a video database, as well as aggregated data from other users, updates to the software application, and other content. The portable electronic device with software application may also communicate data, such as usage data, to a third party, such as a trainer or a physical therapist or medical provider. The device and software application may also communicate with a third party social network, providing the user with a social media engagement. Data regarding the weight device and its use may also be delivered to a database for aggregation with other data, or to the software provider. The device and software application may also communication with a weight device, and in particular with the weight device&#39;s PCB and firmware. The PCB and firmware may then communicate to the weight device, namely the one or more motors in the platform, to select the amount of weight to be retained by the weight device. While specific examples are described, variations thereon may be acceptable for the purposes provided. 
       FIG. 41  provides one or more examples of embodiments of a logic diagram showing the operation of the software application described herein. A user first begins a workout. The user connects his or her portable electronic device to the system, such as connecting the device to a tethered connection cable or other means described herein. The portable electronic device may then prompt to ask if the user is a new user. If the user is a new user, then a new user configuration sequence is generated on the device. The user input in response to this configuration sequence is stored. Then workout options are displayed to a user. If the user is not a new user, then following the new user prompt existing configurations and history are loaded on the portable electronic device. The workout options are then displayed for the user. The user may then select options, i.e., user input, and the input selected options are transmitted from the user device to the weight device, and in particular to the weight device PCB. The PCB then updates or adjusts the weight rods to achieve the corresponding weight on the weight device. The workout video is then displayed to the user on the portable electronic device. The user&#39;s portable electronic device receives workout data from the weight device, updates the user history and data, and proceeds with the workout next steps or next workout segment on the user device. 
     As can be seen in  FIGS. 42-44 , a variety of different types of workouts may be built using the system described herein, including: core and agility; cardio; strength upper body; strength lower body; strength full body; manual control of the workout, and the like. These different workout options may be further adjusted by selection of one of a plurality of levels of difficulty, and workout length (e.g. ranging from 5 minutes to 45 minutes), etc. In some examples, the workout level gradually increase as it is used. 
     The workouts may be “filtered” or built based upon other factors, such as, but not limited to, age, gender, ability, etc., in order to customize a workout to fit the particular user. In one or more further examples of embodiments, the system may be dynamic in that it learns from its user, namely adjusting to the user&#39;s input(s) and/or previous workouts to put together a workout which achieves certain goals. Moreover, the system can also receive and respond to input from the user. The system may also collect and analyze data from all users to build a workout or for other reasons. 
     The app may be comprised of or provide access to and selection from a database of a matrix of different workouts. Each workout may be built from small video segments spliced together, or alternatively from instructions to be communicated via a screen or connected speaker. Each workout may also be tied to a particular weight to be assigned to the weight device (which auto-adjust to the selected weight). In certain examples, instead of streaming a single 30-minute video, several exercise segments are provided which are interchangeable with other segments and “spliced together” for the workout, creating a unique and customized workout that achieves certain predefined parameters, e.g., particular number of reps and sets at a particular weight or multiple weights, with specific rest periods, and different activities. In other words, workout bites or segments are provided. An entire workout may be built by adding and removing workout segments, in much the same way as someone could add and remove weights from a dumbbell or move the pin in a functional trainer to a different weight level. A system with workout segments which may be interchanged is more granular and allows for virtually a limitless range of workouts, which has several benefits. For example, not only can it keep the workouts fresh and varied, but because it is so granular it can allow each successive workout to have very small adjustments to the difficulty, as the user becomes more fit. Also, storing video data in small 5 second bits, and then adding them together requires much less data than a full 30 minute workout video, so the streaming of the workout is much more efficient. 
     The weight can be adjusted such as shown in  FIG. 45 ; and data on the workout is also collected and communicated to the user as shown in  FIGS. 49-50 . In one example such as shown in  FIGS. 46-48 , the app also will show a “workout buddy” on the screen of the portable electronic device in which the user can follow along with the number and pace of each rep, as well as the order of each exercise and the recommended amount of rest. 
     Alternatively, the user can override any of these components of a workout. For instance, if an arm curl exercise has a default of 20 lb, the user could manually increase the weight to 24 lb by selecting a button on the screen (see  FIG. 45 ). Similarly, the user could manually modify the number of reps, number of sets, or the rest time in the workout with the touch of a button on the screen of the portable electronic device  104 . At the end of the workout, the user could proportionally increase or decrease the difficulty for next time with the touch of a button (meaning the weight, number of reps, number of sets and rest time could all be proportionally increased or decreased). 
     During use of the system described herein, a variety of data may be collected and stored. Examples include, but are not limited to, the type of workout or activity, the amount of weight, the amount of reps, the amount of time, and so forth. The data can also be collected over a period of time (e.g., days, months, years). As shown in  FIG. 48-49 , data may also be displayed or communicated to a user. While specific examples are provided, it is understood that any number of variables or data points may be used, collected, stored, and/or communicated by the system in a variety of ways. 
     While an app based system is described, it is also contemplated that weight selection buttons, keys, or any other selection mechanism, including but not limited to an integrated screen, may be provided on the platform  102  for the user to select a desired weight of dumbbell. Likewise, a workout program of the type described herein may be used independent of the weight device  100  and system described herein (e.g., may be used with more traditional weights or weight machines or other weight or exercise systems). 
     As indicated, the system and methods described herein may be implemented in or by software or a software application (for example, to build the workout program and control the selection of weight rods). To this end, the methods may be implemented in a general-purpose software package or a specific purpose software package. Likewise, the system and methods described herein could include performing data analysis manually. The system may comprise a sensor, voltage source, and other systems for analyzing data. 
     As described herein, in one or more examples of embodiments, the system, method, and devices described, or method embodied by software, may be implemented by a computer system or in combination with a computer system. The computer system may be or include a processor. The computers for use with the methods and various components described herein may be programmable computers which may be special purpose computers or general purpose computers that execute the system according to the relevant instructions. The computer system can be an embedded system, a personal computer, notebook computer, tablet computer, server computer, mainframe, networked computer, handheld computer, personal digital assistant, workstation, and the like. Other computer system configurations may also be acceptable including, cell phones, mobile devices, multiprocessor systems, microprocessor-based or programmable electronics, network PC&#39;s, minicomputers, and the like. Preferably, the computing system chosen includes a processor suitable in size to efficiently operate one or more of the various systems or functions. 
     The computer can also include a display, provision for data input and output, etc. These devices include a graphical user interface (GUI) or a communication means by which commands may be entered and content may be displayed or communicated. For example, the computer may include a user interface that allows navigation of objects. The computer may implement or include a software application that enables a user to display and interact with text, images, videos, data, and other information and content. 
     Furthermore, the computer or computers may be operatively or functionally connected to one or more mass storage devices, such as, but not limited to, a database. The memory storage can be volatile or non-volatile and can include removable storage media. The system may also include computer-readable media which may include any computer readable media or medium that may be used to carry or store desired program code that may be accessed by a computer. The invention can also be embodied as computer readable code on a computer readable medium. To this end, the computer readable medium may be any data storage device that can store data which can be thereafter read by a computer system. 
     The systems and devices described may include physical hardware and firmware configurations, along with hardware, firmware, and software programming that is capable of carrying out the currently described operations and methods. 
     The system or portions thereof may also be linked to a distributed computing environment, where tasks are performed by remote processing devices that are linked through a communications network. To this end, the system may be configured or linked to multiple computers in a network, including, but not limited to a local area network, a wide area network, a wireless network, and the Internet. Therefore information and data may be transferred within the network or system by wireless means, by hardwire connection or combinations thereof. For example, in certain embodiments a wireless connection may allow for communication between a trainer and a client or a physical therapist and a client, so that the trainer or therapist may receive actual data of what the client did. 
     Aspects of the method described herein can be implemented on software running on a computer system. The system or method herein, therefore, may be operated by computer-executable instructions, such as but not limited to program modules, executable on a computer. Examples of program modules include, but are not limited to, routines, programs, objects, components, data structures and the like which perform particular tasks or implement particular instructions. The software system may also be operable for supporting the transfer of information within a network. 
     Accordingly, as detailed herein-above, an auto-adjustable weight device  100  is disclosed that comprises a weight retainer  106  comprising one or more receptors  110 ; one or more weight rods  108  sized to be received in the one or more receptors  110 ; and a selector mechanism configured to select one or more weight rods  108  and secure the weight rods  108  in the weight retainer  106 . The selector mechanism may be composed of one or more of the rotating disks  116 , rotating tabs  122 , motor  120 , and/or software executing instructions to drive activation and rotation. 
     An auto-adjustable weight system is also disclosed. The auto-adjustable weight system includes a weight device  100  having a weight retainer  106  which receives one or more weight rods  108 , the weight rods  108  being selectively and removably retained within the weight retainer  106 . A platform  102  receives the weight device  100  and carries one or more weight rods  108  not selected and retained within the weight retainer  106 . A software application in communication with the platform  102  or weight device  100  is configured to select the number of weight rods  108  to be retained within the weight retainer  106 . 
     A physical training system is also disclosed. The system includes a weight device  100  having a weight retainer  106  which receives one or more weight rods  108 . The weight rods  108  are selectively and removably retained within the weight retainer  106 . A platform  102  receives the weight device  100  and carries one or more weight rods  108  not selected and retained within the weight retainer  106 . A software application is provided in communication with the platform  102  or weight device  100  and configured to drive selection of the number of weight rods  108  to be retained within the weight retainer  106 . A database of selectable workout segments is also provided, wherein the application selects and executes a selectable workout segment from the database of selectable workout segments simultaneously with the selection of one or more weight rods  108  which are retained by the weight device  100 . 
     Accordingly, a weight device, system, and method are disclosed that leverage the functionality or take advantage of the potential and versatility of the weight device during exercise or physical fitness routine and further let the user focus on exercise rather than changing weight. As disclosed, an auto-adjustable weight device is provided that is combined with a software application executed by a portable electronic device. In addition unlike existing “selectorized” dumbbells or functional trainers, there are no knobs to turn or pins to adjust on the novel weight device disclosed herein. The weight adjustment may happen through the integrated app, and mechanism discussed. Strength training of any type requires a higher degree of understanding than cardio workouts. For strength training, many if not most users don&#39;t understand which movements are helpful vs. which can lead to injury. Also, knowing how hard to push and how to arrange the different exercises is not clear to many users. In contrast, the weight system disclosed herein can figure everything out for the user: pace, difficulty, weight, length, type of workout. This can make the workout more engaging. The app also allows people to connect from home; either with an instructor at the gym, or a group of users, all connected from their homes, or with a physical trainer or physical therapist. By making the fitness experience easier to figure out, and more connected to a fitness community, the user is more likely to stay engaged. These and other features and advantages of devices, systems, and methods according to this invention may be described in, or are apparent from, the foregoing description. 
     As utilized herein, the terms “approximately,” “about,” “substantially”, and similar terms are intended to have a broad meaning in harmony with the common and accepted usage by those of ordinary skill in the art to which the subject matter of this disclosure pertains. It should be understood by those of skill in the art who review this disclosure that these terms are intended to allow a description of certain features described and claimed without restricting the scope of these features to the precise numerical ranges provided. Accordingly, these terms should be interpreted as indicating that insubstantial or inconsequential modifications or alterations of the subject matter described and claimed are considered to be within the scope of the invention as recited in the appended claims. 
     It should be noted that references to relative positions (e.g., “top” and “bottom”) in this description are merely used to identify various elements as are oriented in the Figures. It should be recognized that the orientation of particular components may vary greatly depending on the application in which they are used. 
     For the purpose of this disclosure, the term “coupled” means the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or moveable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate members being attached to one another. Such joining may be permanent in nature or may be removable or releasable in nature. 
     It is also important to note that the construction and arrangement of the system, methods, and devices as shown in the various examples of embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited. For example, elements shown as integrally formed may be constructed of multiple parts or elements show as multiple parts may be integrally formed, the operation of the interfaces may be reversed or otherwise varied, the length or width of the structures and/or members or connector or other elements of the system may be varied, the nature or number of adjustment positions provided between the elements may be varied (e.g. by variations in the number of engagement slots or size of the engagement slots or type of engagement). The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. Other substitutions, modifications, changes and omissions may be made in the design, operating conditions and arrangement of the various examples of embodiments without departing from the spirit or scope of the present inventions. 
     Moreover, some portions of the detailed descriptions herein are presented in terms of procedures, steps, logic blocks, processing, and other symbolic representations of operations on data bits that can be performed on computer memory. These descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. A procedure, computer executed step, logic block, process, etc., is here, and generally, conceived to be a self-consistent sequence of steps or instructions leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated in a computer system. It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the discussions herein, it is appreciated that throughout the present invention, discussions utilizing terms such as “receiving,” “sending,” “generating,” “reading,” “invoking,” “selecting,” and the like, refer to the action and processes of a computer system, or similar electronic computing device, including an embedded system, that manipulates and transforms data represented as physical (electronic) quantities within the computer system. 
     While this invention has been described in conjunction with the examples of embodiments outlined above, various alternatives, modifications, variations, improvements and/or substantial equivalents, whether known or that are or may be presently foreseen, may become apparent to those having at least ordinary skill in the art. Accordingly, the examples of embodiments of the invention, as set forth above, are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit or scope of the invention. Therefore, the invention is intended to embrace all known or earlier developed alternatives, modifications, variations, improvements and/or substantial equivalents. 
     The technical effects and technical problems in the specification are exemplary and are not limiting. It should be noted that the embodiments described in the specification may have other technical effects and can solve other technical problems.
