Description:
This is a continuation application of application Ser. No. 12/019,207, filed Jan. 24, 2008, the content of which is incorporated herein by reference in its entirety. 
    
    
     FIELD OF THE INVENTION 
     The present invention generally relates to training devices, and more particularly to mobile training devices for simultaneous use by multiple users. 
     BACKGROUND OF THE INVENTION 
     Physical exercise is an important activity undertaken by many individuals to maintain their physical fitness. It has been shown, for example, that physical fitness contributes positively toward maintaining healthy body weight; building and maintaining healthy bone density, muscle strength, and joint mobility; promoting physiological well-being; reducing surgical risks; and strengthening the immune system. 
     Many physical exercise activities, however, such as running, mountain climbing, skiing, etc., require the correct outdoor terrain to support such activities. As such, many outdoor activities do not lend themselves conveniently for physical exercise. Thus, many individuals utilize indoor facilities instead, which offer specialized exercise equipment that may be accessed much more readily. 
     Public fitness centers, for example, offer a wide variety of exercise equipment within a relatively small proximity. As such, each individual may obtain convenient access to a piece of cardiovascular exercise equipment, for example, while maintaining close proximity access to other specialized fitness equipment, such as strength training equipment. 
     In many instances, however, athletes that require specialized fitness equipment, such as martial arts athletes, cannot find equipment within the public fitness centers that is suitable for martial arts training. As such, martial arts athletes are often required to provide their own specialized training equipment and are then relegated to train at locations such as gymnasiums, garages, rented or private facilities, parks, backyards, beaches, etc. 
     Martial arts athletes that train in such facilities, therefore, are often required to temporarily assemble the specialized training equipment in order to support the plurality of workout regimes that may be utilized by a typical group of martial arts athletes. The temporary accommodations are adequate, but generally require disassembly of the specialized training equipment once the workout regimes have been completed. Thus, valuable time and effort is wasted during setup/teardown of the temporary training equipment. 
     In addition, given that the equipment is setup for temporary use, the equipment often exhibits less than optimum structural integrity. Thus, a first martial arts athlete is often required to stabilize the equipment, while a second martial arts athlete executes the workout regime on the temporarily stabilized equipment. As such, workout efficiency is significantly reduced because the first and second athletes must switch positions after the first athlete completes the workout regime, which essentially doubles the amount of time required for two athletes to achieve a complete workout. 
     Furthermore, the temporarily deployed training equipment is often utilized within a gymnasium, or other facility, in support of martial arts competitions. As such, the training equipment is deployed during, e.g., warm-up or exhibition exercises, but is then required to be disassembled, relocated, and then reassembled in another area within the gymnasium in support of other competition activities. The lack of mobility offered by conventional training equipment is, therefore, another source of time inefficiency, since teardown/setup activities must be executed each time the training equipment is to be relocated. 
     Efforts continue, therefore, to develop a training solution that not only offers a full complement of physical training equipment, but also provides mobility for a relocatable solution that facilitates multiple exercise positions simultaneously. 
     SUMMARY OF THE INVENTION 
     To overcome limitations in the prior art, and to overcome other limitations that will become apparent upon reading and understanding the present specification, various embodiments of the present invention disclose a method and apparatus that provides a full complement of specialized martial arts equipment and/or generalized physical exercise equipment. The method and apparatus of the present invention also provides mobility for a relocatable training apparatus that facilitates multiple exercise/workout positions simultaneously. 
     In accordance with one embodiment of the invention, a method of utilizing a physical training device comprises providing a channel within frame members of the physical training device, slidably configuring a position of one or more workout stations to the channel of the frame members of the physical training device, engaging mobility devices of the physical training device to deploy the physical training device to a desired location, and disengaging the mobility devices of the physical training device to stabilize the physical training device at the desired location. 
     In accordance with another embodiment of the invention, a method of utilizing a physical training device comprises providing a plurality of frame members for the physical training device, slidably configuring a position of one or more workout stations along at least one of the plurality of frame members, and securing the slidably configured position of each of the one or more workout stations to the at least one of a plurality of frame members. 
     In accordance with another embodiment of the invention, a method of utilizing a plurality of physical training devices comprises providing a channel within frame members of the plurality of physical training devices, slidably configuring a position of one or more workout stations to the channel of one or more frame members of the plurality of physical training devices, securing the slidably configured position of each of the one or more workout stations, and deploying the plurality of physical training devices as a cluster of physical training devices.

     DETAILED DESCRIPTION 
     Generally, various embodiments of the present invention are applied to the field of physical training devices. In particular, physical training devices are provided to accommodate one or more athletes during support of a plurality of independent training scenarios for each athlete. In one embodiment, the physical training device provides a plurality of training stations, where each training station may be specific to martial arts training activities, or may be generalized to facilitate training that is effective for a plurality of other sporting disciplines. Each training station may then be utilized by a single athlete, so that independent training regimes may be executed simultaneously for each athlete that occupies a training station. Once each athlete completes a training scenario at a particular workout station, each athlete may then rotate to the next respective workout station existing on the physical training device to complete the training scenario on the next workout station. 
     By accommodating multiple workout stations within a single physical training device, each athlete is allowed to focus on his or her own workout scenario, without having to provide support to other athletes during their respective workout scenarios. That is to say, in other words, that the physical training device provides a sufficient number of workout stations with a high degree of structural integrity, so that multiple athletes may execute individual workout scenarios simultaneously. Once specific activities during a first portion of the specific workout regime have been completed, each athlete may rotate his or her position relative to the physical training device, so as to execute a subsequent portion of the specific workout regime. Completion of subsequent rotations is effective to provide each athlete with a complete workout according to his or her workout regime, without additionally requiring each athlete to provide support activities for other athletes. As such, each athlete maximizes his or her workout efficiency during his or her workout regime. 
     In addition, the physical training device provides mobility features that facilitate maneuvering and reconfiguration of the physical training device. In one embodiment, for example, removable casters are provided at a bottom surface of the physical training device, so as to allow relocation and reconfiguration of the physical training device during, e.g., training or exhibition events. The removable casters may be composed of a sufficiently rigid material and appropriately sized so as to facilitate movement of the physical training device across a relatively hard and flat surface, such as a gymnasium floor. In an alternate embodiment, the removable casters may be composed of a sufficiently flexible material and appropriately sized so as to facilitate movement of the physical training device across a substantially non-flat and soft surface, such as a sandy beach. In such an instance, the casters may be implemented with an inflatable rubber material, so as to further enhance traversal over soft terrain. 
     Lifting devices may also be configured along the bottom surface of the physical training device, so as to provide a mechanism whereby the casters of the physical training device may be lifted off of the surface that is supporting the casters. In one embodiment, pneumatically controlled lifting devices may be actuated so as to elevate the casters just above the supporting surface. In such an instance, the pneumatically controlled lifting devices may function as stationary platforms for the physical training device during a training or exhibition event while the pneumatically controlled lifting devices remain in their fully deployed positions. The pneumatically controlled lifting devices may be activated and deactivated via any convenient actuation device, such as a manual switch or remote control, so as to maximize convenience. 
     In an alternate embodiment, the casters may either be removed, or installed in an inverted position, while the pneumatically controlled lifting devices are fully deployed. The pneumatically controlled lifting devices may then be deactivated to a fully retracted position while functioning as stationary platforms for the physical training device during the training or exhibition event. In other embodiments, the pneumatically controlled lifting devices may remain in their fully retracted positions while the casters function as stationary platforms for the physical training device during the training or exhibition event. In such an instance, the casters may be locked so as to prevent rotation of the casters. 
     In accordance with one embodiment, the physical training device may be utilized in a stand-alone configuration. As such, the number of athletes that may be simultaneously accommodated by the stand-alone configuration is equal to the number of workout stations provided by the physical training device. As discussed in more detail below, the physical training station may include a multitude of workout stations, such as: one or more speed-bag stations; one or more speed-ball stations; one or more heavy punching bag stations; one or more pull-up bar stations; a Wing Chun station; a monkey-bar station; a body-shield station; and a board, breaking station to name only a few. 
     Each physical training device may also include features such as an equipment storage cage, whereby in one embodiment, martial arts weapons and equipment, such as swords, nunchucks, throwing stars, fighting gloves, etc., may be stored during non-use. The equipment storage cage may also feature a locking mechanism, so that the physical training device may be left unattended without risk of uninvited access to the contents of the equipment storage cage. A media center may also be provided by the physical training device, so as to facilitate audio/video instruction during execution of the one or more workout scenarios. 
     In accordance with an alternate embodiment, two or more physical training devices may be interconnected, so as to provide a localized cluster of physical training devices. In such an instance, the number of athletes that may be simultaneously accommodated by the cluster configuration is equal to the combined number of workout stations that are provided by all of the physical training devices interconnected within the cluster. 
     As discussed in more detail below, the cluster configuration may be facilitated through the use of an exhibition cage, whereby each physical training device is interconnected to a respective supporting member of the exhibition cage. In such an instance, a plurality of workout scenarios may be facilitated by the two or more physical training devices that are interconnected to an exterior region, as defined by the exhibition cage, while an exhibition or competition match is facilitated within an interior region as defined by the exhibition cage. In other embodiments, a cluster of physical training devices may be arranged without the need for the exhibition cage, whereby each stand-alone physical training device is situated in close proximity to other physical training devices in accordance with the particular training scenario that is desired. 
     Turning to  FIG. 1 , physical training device  100  exhibiting a plurality of workout stations is illustrated in accordance with one embodiment of the present invention. In particular, workout stations provided by physical training device  100  include heavy punching bag station  102 , speed-ball station  104 , speed-bag station  108 , pull-up bar station  110 , body-shield station  112 , Wing Chun station  114 , and monkey-bar station  116 . It should be noted that the relative placement of each workout station is configurable. Thus, the stand-alone configuration of  FIG. 1  is representative of only one of many possible configurations that may be employed. 
     An alternate configuration, for example, may include the relocation of heavy punching bag station  102  from lateral bar  202  of monkey-bar station  116 , as illustrated in  FIG. 2 , to one of the remaining lateral bars of monkey-bar station  116 , e.g., lateral bar  204  or  206 . Alternately, heavy punching bag station  102  may instead be configured on either side of monkey-bar station  116  along longitudinal frame member  118  or longitudinal frame member  136 . Similarly, pull-up bar station  110  may be positioned along longitudinal frame member  136  closer to speed-bag station  108  and body-shield station  112 , as illustrated. Pull-up bar station  110  may also be centered along longitudinal frame member  136 , or conversely, positioned along longitudinal frame member  136  closer to speed-ball station  104  and equipment cage  106 . In alternate embodiments, as discussed below in relation to  FIG. 8  for example, multiple pull-up bar stations  110  may be positioned along longitudinal frame member  118  and longitudinal frame member  136  so as to accommodate multiple athletes who wish to simultaneously execute their respective workout scenarios on pull-up bar stations  110 . 
     Turning to  FIG. 3A , one embodiment of frame arrangement  300  that may be used to implement the various frame members of the physical training device is illustrated. Frame arrangement  300  is implemented as a rigid structure, such as an extruded aluminum structure, that provides channels  302  and hollow portions  310  and  312 . Channels  302  may be implemented on all four sides of frame arrangement  300  as illustrated, so as to provide, for example, six channels for each frame member. Hollow portions  310  and  312 , as discussed in more detail below, facilitate the attachment of utility devices, such as casters  122 , to the end points of lateral frame members  124  as shown, for example, in the physical training devices of  FIGS. 1 and 8 . 
     Channels  302  are configured to accept a multitude of fastening systems, such as the combination of screw  306  and wingnut  308 . In particular, head portion  304  aligns with channels  302 , so that insertion of head portion  304  into channel  302  at the end points of frame arrangement  300  allows screw  306  to be slidably positioned along the length of frame arrangement  300 . Once an adequate position of screw  306  along the length of frame arrangement  300  is located, wing nut  308  may be threaded onto screw  306  and tightened so as to prevent further repositioning of screw  306 . 
     Alternate fastening systems, such as illustrated in  FIG. 3B , may also be utilized in much the same manner. Fastener  322  may be inserted into the channel of frame member  320  as illustrated and subsequently tightened into place using a set screw (not shown) that is mechanically fastened to threaded receiver portion  324 . Fastener  322  may be slidably positioned along the channel of frame member  320  so as to accommodate the configurable fastening of workout stations along the full length of frame member  320  as required. 
     Ergonomic aspects may also be incorporated along frame arrangement  300  as well as illustrated in  FIG. 3C . For example, hand guards  330  may be mounted to one or more sides of frame arrangement  300  so as to facilitate a smooth grip while an athlete is executing his or her workout scenario while using, e.g., monkey-bar station  116  of  FIG. 1 . In one embodiment, hand guards  330  may be composed of a rigid plastic material, such as polyvinyl chloride (PVC), and coated with an ultraviolet light protectant for outdoor use. Similar PVC guards may also be utilized to provide safety aspects to the physical training device. In particular, PVC guards  330  may be mounted to each frame member to create a smooth, rounded contour on each side of the frame member so as to reduce the incidence of injury in the event physical contact is made between the athletes and the frame members. 
     Turning to  FIG. 3D , mounting anchors  340  may be utilized at each end of frame members  348  to facilitate mechanical engagement of frame member  348  to frame member  350 . In particular, mounting anchors  340  may be utilized to facilitate the mechanical engagement of one frame member that is orthogonally incident to another frame member. Locking member  346  may be inserted into channel  302  of frame member  350  while anchor  340  is inserted into slot  342  of frame member  348 . Locking member  346  and anchor  340  may then be mechanically engaged/disengaged in direction  344  as necessary to secure/loosen the mechanical engagement between frame members  348  and  350  as necessary. 
     Turning back to  FIG. 1 , lateral frame members  144  of pull-up bar station  110 , for example, may be slidably attached to longitudinal frame member  136  using the fastening system as discussed above in relation to  FIG. 3D . As such, the position of pull-up bar station  110  along the full length of longitudinal frame member  136  may be selected and then secured by the tightening of anchor  340  and locking mechanism  346 . Similarly, lateral frame members  146  of monkey-bar station  116  may be slidably attached to longitudinal frame members  118  and  136  using a similar combination of fastening systems to configure the separation distance between each of lateral frame members  146  of monkey-bar station  116 . In an alternate embodiment, lateral frame members  146  of monkey-bar station  116  may instead be permanently mounted to longitudinal frame members  116  and  136  using any number of mechanical fastening mechanisms, such as TIG welding, to permanently select the separation distance between each of lateral frame members  146 . 
     The use of slidably attached mechanisms to adjoin two or more intersecting frame members and the attachment of the various workout stations to one of the intersecting frame member sets facilitates the correct positioning of the various workout stations of the physical training device. Turning to  FIG. 4 , for example, support platform  402  of speed-bag station  108  may be slidably attached to vertical frame members  406  and  408 , using mounting brackets  404  and the fastening systems discussed above, so as to select the correct height of speed-bag station  108 . Support platform  410  of body-shield station  112 , as well as support platform  412  of speed-ball station  104 , may also be slidably attached to their respective frame members so as to properly adjust their height as well. 
     Turning back to  FIG. 1 , individual components of each workout station may be repositioned to accommodate differently sized athletes. Wing Chun station  114 , for example, provides height adjustable components, such as one or more arm components  126 , a mid-section component  128 , and a leg component that contains various sub-components, such as upper leg component  130 , joint component  132 , and lower leg component  134 . Each component  126 - 136 , for example, is height adjustable using slidably attached mechanisms as discussed above in relation to  FIGS. 3A ,  3 B, and  3 D. As such, correct vertical positioning of each component may be adjusted in accordance with the height of a particular martial arts athlete, so as to facilitate the proper execution of the martial art of Wing Chun, to include facilitation of the hand and footwork techniques that are incorporated into the martial art of Wing Chun. 
     Turning to  FIG. 5 , additional mechanical aspects of a physical training device are illustrated. In particular, one of several casters  122  may provide locking mechanism  502 , which is engaged to prevent rotation of caster  122  along the associated supporting surface, when casters  122  are utilized to provide stationary platforms for the physical training device. Locking mechanism  502  may alternately be disengaged when casters  122  are utilized to provide mobility for the physical training device. 
     Lifting devices may also be configured along bottom surface  522  of, e.g., lateral frame members  124 , so as to provide a mechanism whereby casters  122  of the physical training device may be lifted off the supporting surface for the physical training device. In particular, pneumatically controlled lifting devices, such as pneumatic discs  504 , may be actuated so as to elevate casters  122  to a position that is just above the supporting surface. In such an instance, pneumatic discs  504  are inflated until supporting members  506  and  508  engage the supporting surface, so as to elevate caster  122  in direction  512  relative to the supporting surface. In such an instance, supporting members  506  and  508  function as stationary platforms for the physical training device during a training or exhibition event while pneumatic disks  504  remain in their fully deployed positions. 
     In an alternate embodiment, casters  122  may either be removed, installed in an inverted position, or left in a mobility configuration while pneumatic disks  504  are fully deployed. Turning to  FIGS. 6A and 6B , for example, mechanisms allowing the mounting and removal of casters  122  are illustrated. As discussed above in relation to  FIG. 3A , lateral frame members  124  may be comprised of frame arrangement  300  having hollow portions  310  and  312 . Pins  602  and  604  may then be inserted into hollow portions  310  and  312  of frame members  124  so as to facilitate mounting of casters  122  in the mobility configuration as illustrated is  FIG. 6B . Alternately, casters  122  may be installed in an inverted configuration, as illustrated in  FIG. 6A , so that pneumatic disks  504  may be deactivated to a fully retracted position while functioning as stationary platforms for the physical training device during a training or exhibition event. In such an instance, casters  122  are inverted and, therefore, do not engage the supporting surface when pneumatic disks  504  are deactivated to a fully retracted position. In other embodiments, pneumatic disks  504  may remain in their fully retracted positions while casters  122  are installed in the mobility configuration of  FIG. 6B , but are locked to prevent rotation, so as to function as stationary platforms for the physical training device during a training or exhibition event. 
     In a first embodiment, pneumatic discs  504  may be inflated/deflated using a combination of air compressor (not shown) and intake/exhaust valve (not shown), and air tubing (not shown), so as to effectuate the raising and lowering of the physical training device as discussed above. Furthermore, the air compressor and intake/exhaust valve may be actuated manually, or via remote control, whereby in a first mode of operation, the intake/exhaust valve is configured as an intake valve and the compressor is actuated to inflate pneumatic disk  504 , thus raising the physical training device in direction  512 . Alternately, the intake/exhaust valve may be configured as an exhaust valve, thus lowering the physical training device in direction  510 . 
     It should be noted that placement of the compressor and the intake/exhaust valve may be on surface  522 , or may be placed in any other convenient location where concealment and protection of the compressor and the intake/exhaust valve may be optimized. Air tubing may be routed to pneumatic disks  504  from the compressor and the intake/exhaust valve using the cavities of frame arrangement  300 , such as hollow portions  310 ,  312  and/or channels  302 , as discussed above in relation to  FIG. 3A . 
     Turning to  FIG. 7A , a portion of the interior features of equipment cage  106  of  FIG. 1  are illustrated. In particular, a media center comprised of, for example, media player  704  and display device  702  may be housed within equipment cage  106  as illustrated. Media player  704  may include one or more data storage devices, including hard and floppy disk drives, CD/DVD drives, and other hardware capable of accessing stored data and/or audio/video information. Media player  704  is coupled to display device  702 , which may be any type of known display or presentation screen, such as an LCD display, plasma display, cathode ray tube (CRT), etc. 
     In operation, the media center may be used by the one or more athletes as an audio/visual aid during execution of their respective workout scenarios. The training information provided by the media center may be consumed either while door  706  of equipment cage  106  is open, or conversely, while door  706  of equipment cage  106  is closed. Consumption of audio/video information while door  706  remains closed is made possible by the wire mesh configuration of equipment cage  106 , which allows the audio/video information to egress equipment cage  106  even while the door of equipment cage  106  remains closed. 
     The wire mesh configuration of equipment cage  106  is further illustrated in  FIG. 7B , whereby wire mesh  714  may be comprised of powder coated steel. Mechanical fasteners  716 - 720  may be utilized to secure wire mesh  714  into the channels  302  of frame members  710  and  712  as illustrated. In particular, bracket  716  may be locked into channels  302  by engaging the right angled portion of bracket  716  into channels  302 . Fasteners  718  and  720  may then be mechanically engaged so as to clamp wire mesh  714  to bracket  716  to complete the assembly of wire mesh  714  within frame members  710  and  712  as illustrated. 
     Turning to  FIG. 8 , an alternate embodiment of a physical training device is illustrated, whereby multiple pull-up bar stations  110  are configured along longitudinal frame member  118  and  136  as illustrated. Furthermore, additional workout stations, such as strike board station  802  and speed-ball stations  104  round out the complement of workout stations that may be configured at each corner of physical training device  800 . In addition, physical training device  800  is configured with the lifting mechanisms as discussed above in relation to  FIG. 5 . It should be noted, that the physical training devices of  FIGS. 1 and 8  are merely representative of a plurality of configurations that may be implemented. It is understood, therefore, that various other configurations may be similarly implemented in accordance with the particular workout regimes that may be required to be executed of physical training devices. 
     Strike board station  802 , for example, may be comprised of multiple strike boards  808 - 812  that are arranged in various configurations depending upon the particular strike training regime that is to be employed. Strike boards  808  and  810 , for example, may facilitate a strike training regime to improve the execution of front kicks, side kicks, roundhouse kicks, front punches, reverse punches, etc. Strike board  812  may be used to further improve the flexibility of the athlete, since either foot or hand of the athlete is required to contact strike board  812  despite the fact that the position of strike board  812  is adjusted, for example, above the head of the athlete. 
     Frame members utilized for the support of strike boards  808 - 812  may be comprised of frame arrangement  300 , as discussed above in relation to  FIG. 3A , whereby clamp members  814  may be slidably attached to one or more sides of the frame members so as to allow strike boards  808 - 812  to be temporarily mounted at various angles with respect to physical training device  800 . That is to say, in other words, that while strike board  808  may be temporarily attached to strike-board station  802  to be substantially parallel with lateral frame member  124 , as illustrated, strike board  808  may instead be temporarily attached to strike-board station  802  using clamp member  814  so as to rotate strike board  808  to be substantially orthogonal to lateral frame member  124 . 
     Turning to  FIG. 9 , a close-up view of one embodiment of the arrangement of strike boards and associated clamp members is illustrated. Clamp members  814  may be comprised of lever  902  that is actuated by spring component  904  mounted between lever  902  and frame member  906  as illustrated. Applying downward force  908  on lever  902  allows the removal of strike board  910  and subsequent replacement of strike board  910  once strike board  910  is rendered unusable for its intended purpose. Release of downward force  908  allows clamp member  814  to apply a restraining force against strike board  910  to temporarily hold strike board  910  in place during a particular strike training regime. 
     Turning to  FIG. 10 , an alternate embodiment is illustrated, whereby two or more physical training devices may be interconnected, so as to provide a localized cluster of physical training devices. In particular, any number of physical training devices, such as those described above in relation to  FIGS. 1  and/or  8 , may be interconnected using exhibition cage  1002 . In such an instance, frame members  1004  are utilized to provide mechanical engagement with exhibition cage  1002 , so as to form a substantially circular arrangement of physical training devices as illustrated. 
     As can be verified, a large number of athletes may be simultaneously accommodated by the cluster configuration of physical training devices of  FIG. 10 . In addition, the interior of exhibition cage  1002  may be accessed, so that while the multitude of athletes are simultaneously executing their respective workout scenarios on the cluster configuration of physical training devices, two or more athletes may be engaged in an exhibition/combat match within exhibition cage  1002 . 
     It should be noted, that since the physical training devices described herein may be deployed in stand-alone configurations, exhibition cage  1002  is an optional component. That is to say, in other words, that virtually any other cluster configuration, i.e., non-circular, may be implemented using any number of physical training devices in their respective stand-alone configurations as required. 
     Turning to  FIG. 11 , a method of utilizing one or more of the physical training devices provided herein is illustrated. In step  1102 , it is determined whether the physical training device is to be used by itself, or in conjunction with other physical training devices. If a single physical training device is to be utilized, then step  1104  provides that a single physical training device is to be deployed to locations such as gymnasiums, garages, rented or private facilities, parks, backyards, beaches, etc. 
     In order to facilitate the deployment of the physical training device, as in step  1104 , removable casters, as discussed above in relation to  FIG. 5 , are provided at a bottom surface of the physical training device, so as to allow relocation and reconfiguration of the physical training device. The removable casters may be composed of a sufficiently rigid material, such as solid rubber or polyurethane, and appropriately sized so as to facilitate movement of the physical training device across a relatively hard and flat surface, such as a gymnasium floor. In an alternate embodiment, on the other hand, the removable casters may be composed of a sufficiently flexible material, e.g., air-filled rubber, and appropriately sized so as to facilitate movement of the physical training device across a substantially non-flat and soft surface, such as a sandy beach. It is understood that casters to be used across a non-flat, soft surface should be considerably larger in diameter and considerably more flexible as compared to the solid rubber casters as discussed above. 
     If, on the other hand, more than one physical training device is to be utilized, then step  1108  determines whether the cluster of physical training devices are to be utilized in a substantially circular configuration, or whether the cluster of physical training devices are to be utilized in a substantially random configuration. If a random configuration is desired, then step  1106  is executed, whereby stand-alone configurations of each physical training device are deployed randomly as may be required by the particular application. If a substantially circular configuration is desired, then step  1110  is executed, whereby in one embodiment, each physical training device is mechanically engaged to an exhibition cage, as discussed above in relation to  FIG. 10 . 
     Once each physical training device is deployed, then the mobility mode of each physical training device is determined as in step  1112 . In particular, if the mobility mode for each physical training device is to be deactivated, as determined in step  1112 , then lifting devices, such as pneumatic disks  504  may be activated in step  1114  to hoist the physical training device off of the associated supporting surface. In step  1116 , casters  122  may then be removed, or configured into an inverted configuration, as discussed above in relation to  FIG. 6A . In step  1122 , pneumatic disks  504  may then be deactivated to a fully retracted position to function as stationary platforms for the physical training device as in step  1122 . In such an instance, casters  122  are either inverted or removed and, therefore, do not engage the supporting surface when pneumatic disks  504  are deactivated to a fully retracted position. 
     If, on the other hand, the mobility mode for each physical training device is to remain activated, as determined in step  1112 , then either casters  122  or support members  506 / 508  provide support for the physical training device as determined in step  1118 . If casters  122  are to provide support, as determined in step  1118 , then locking mechanism  502  is engaged in step  1120 , as discussed above in relation to  FIG. 5 , to prevent casters  122  from rotating. Otherwise, pneumatic disks  504  are fully activated in step  1124 , while casters  122  remain in the mobility configuration of  FIG. 6B , so that support members  506 / 508  may provide support for the physical training device. 
     In optional step  1126 , the use of slidably attached mechanisms, as discussed above, are used to configure the correct positioning of the various workout stations of the physical training device(s) if necessary. It should be noted, however, that the correct positioning of the various workout stations of the physical training device(s) may be selected prior to execution of steps  1102 - 1124 , thus making step  1126  an optional execution step if correct positioning has already been implemented. The support platform of a speed-bag station, for example, may be slidably configured to the associated vertical frame members, so as to select the correct height of the speed-bag station. The support platforms of the body shield and speed-ball stations may also be slidably attached to respective frame members so as to properly adjust their height as well. The various strike boards of the physical training device may be similarly configured using slidable adjustments, whereby the orientation of the strike boards may be further configured using associated clamp members. Once usage of the physical training device(s) has terminated, then the mobility aspects of each physical training device may be reactivated for relocation of the physical training devices as required.
