PRIORITY CLAIM 
     This application claims the benefit of provisional patent application No. 61/606,303 titled “Resistance based multi-functional exercise station” filed Mar. 2, 2012, hereby incorporated by reference as though fully set forth herein. 
    
    
     BACKGROUND 
     Research shows that physical inactivity is a fast growing public health problem in many countries and contributes to a variety of chronic diseases and health complications, including obesity, coronary artery disease, diabetes, high blood pressure, cancer, depression and anxiety, arthritis and osteoporosis. In addition to improving a patient&#39;s overall health, increasing physical activity as little as 10-15 minutes a day has proven effective in the treatment and prevention of chronic disease. Studies indicate that physical activity need not be strenuous to be beneficial. Regular physical activity improves strength, builds lean muscle, decreases body fat, and can build stronger bones to last a lifetime. The Surgeon General&#39;s Report on Physical Activity and Health documented research that indicated men and women of all ages and abilities can improve their quality of life through regular moderate physical activity. 
     Despite the numerous studies and recommendations by both public and private sector organizations there are numerous reasons why individuals do not incorporate regular exercise regiments into their daily lives. Gymnasiums and fitness centers, while offering a wide array of exercise equipment and customized exercise regiments designed to fit individual needs, are often too expensive for those on a tight budget or intimidating and uncomfortable for those self-conscious about working out in front of others. While there are a myriad of home based exercise devices on the market today many of them go unused. For one reason or another, these devices either lack certain desirable features or they take individuals away from their daily routines.

     DETAILED DESCRIPTION 
     An exercise apparatus is disclosed as it relates to portable exercise devices including resistance bands or tension springs and methods of use. In today&#39;s society time has become a luxury, taking the time to create a daily exercise regimen, in many cases, is not feasible. Considering time as a luxury, there are many times during the average day that individuals have what may be considered as idle time and with the proper exercise device they could use that time effectively. Weight bearing exercise systems, in many cases, are too expensive, too bulky to accommodate economical storage and may pose definitive health risk even for experienced users. 
     Resistance bands and similar resistance media such as the exercise solution discussed herein may be used by individuals of any skill level, personal trainers, physical therapists, and other exercise enthusiasts because of the simple, low-cost design, portability and broad range of fitness and therapeutic applications. The resistance media offers a user the ability to accomplish strength training by building muscle or maintaining muscle tone without many of the risk associated with weight bearing devices. 
     Example resistance media used for exercising are comprised of circular, closed-ended loops of latex; others are linear and include metal or plastic connectors for attachment of secure handles or straps during use. In other examples, tension springs of various lengths and thicknesses may also be used to simulate weight-bearing exercises. The example resistance media may also offer customized features without having to be attached to door knobs or to be mounted to walls to accommodate various exercise positions. 
     While a novel exercise apparatus is demonstrated by a description of various examples, and while these examples are described in considerable detail herein, it is not the intention of the applicant to restrict, or, in any way limit the scope to such detail unless otherwise recited in the claims. A novel exercise apparatus, in its broader aspects, is therefore not limited to specific details or illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of the claims. 
     Before continuing, it is noted that as used herein, the terms “includes” and “including” mean, but is not limited to, “includes” or “including” and “includes at least” or “including at least.” The term “based on” means “based on” and “based at least in part on.” 
     As illustrated in  FIG. 1-2 , an example of an exercise apparatus is shown as it may include a multi-functional upper assembly  2  and a multi-functional lower assembly  3 . Upper assembly  2  and lower assembly  3  may be made of a light weight, high strength plastic, or any of a variety of materials with similar characteristics including but not limited to metal, metal alloys or wood. In an example, upper  2  and lower  3  assemblies may be rectangular however any of a variety of shapes may be provided. 
     A cushion top  1  may be applied to an outer surface of upper assembly  2  (e.g., either removably or permanently). Cushion top  1  may be formed from any of a variety of materials including but not limited to dense rubber, foam or padded upholstery. When provided, cushion top  1  may reduce impact on the user while sitting, kneeling or standing on the exercise apparatus. Cushion top  1  is not limited to the shape depicted and may be provided in any of a variety of shapes capable of reducing impact to the user. 
     Upper  2  and lower  3  assemblies may be hingedly interconnected by a tongue and groove hinge. It is noted that the examples are not limited to the tongue and groove style hinge. Other examples may include but are not limited to piano or butterfly type hinges. With reference to  FIGS. 3-5 , four slots or grooves  27  located at the rear of upper assembly  2  ( FIG. 3 ) are configured to mate with four extrusions or tongues  37  located near the rear of the lower assembly  3  ( FIG. 5 ). A connecting rod  34  ( FIG. 2 ) may be inserted through predrilled holes at the base of each of the upper  2  and lower  3  assemblies allowing the exercise apparatus to open and close when the upper  2  and lower  3  assemblies pivot relative to one another. Connecting rod  34  may be formed of any of a variety of materials including but not limited to a metal or composite material. 
       FIG. 1  illustrates an example closed configuration of the exercise apparatus while  FIG. 2  illustrates an example open configuration. In an example, upper assembly  2  may be capable of pivoting beyond the position depicted in  FIG. 2 , for example to a position in which an angle of 180 degrees is formed between the upper  2  and lower  3  assemblies. 
     As illustrated by way of example in  FIGS. 1-3, 5 and 10 , a slide lock  5 . It is noted that the examples are not limited to the slide lock, and other examples are also contemplated. The slide lock for use with an example exercise apparatus may include an L-shaped upper locking mechanism  26  provided near the front of upper assembly  2  ( FIGS. 1, 2 and 10 ), a T-shaped lower locking mechanism  33  provided near the front of the lower assembly  3  and a T-shaped latch  5  for slidable receipt upon upper  26  and lower  33  locking mechanisms. 
     When an exercise apparatus is in a closed position, as shown by way of example in  FIG. 1 , upper locking mechanism  26  mates with the notch  33   a  on the top left side of the lower locking mechanism  33  ( FIG. 10 ). Latch  5  may slide along the lower locking mechanism  33  in either left or right directions. When the latch  5  slides to the right of the lower locking mechanism  33 , tab  26   a  of upper locking mechanism  26  is not engaged by latch  5  allowing relative pivoting of upper  2  and lower  3  assemblies. When the latch  5  slides to the left of the lower locking mechanism  33 , tab  26   a  is engaged by latch  5 , locking the exercise apparatus and preventing the upper  2  and lower  3  assemblies from relative pivoting. 
     As illustrated in  FIGS. 2 and 5  lower assembly  3  may be a multi-functional assembly comprising two rotary discs  4  positioned to either side of lower assembly  3  over spindles  36 . U-grooves  51  and T-channels  52  of rotary discs  4  may be used to secure resistance bands or tension springs  FIG. 17  to the lower assembly  3 . Spindles  36  are configured to enable each rotary disc  4  to rotate within a plane perpendicular to spindles  36  independently of the opposing disc. Thus, a user may change the orientation of the resistance media held by rotary discs  4 . Rotary discs  4  thereby offer versatility by facilitating transitions between exercise positions. In an example, rotary discs may be D-shaped. 
     In an example, rotary discs  4  are capable of 90 degrees of rotation, for example, between positions with spine  4   a  ( FIG. 5 ) of the ‘D’ towards the upper  2  and lower  3  assembly fronts and positions with the spine  4   a  of the ‘D’ towards the upper and lower assembly sides. In an example, rotary discs  4  may be capable of different degrees of rotation. 
     With U-grooves  51  and T-channels  52 , each rotary disc  4  can accommodate a variety of the most common types of resistance media including but not limited to linear open end or circular closed loop resistance bands and metal tension springs. Some of these resistance media are depicted by way of example in  FIG. 17 . 
     In an example use of rotary discs  4 , closed loop resistance bands may be accommodated within U-grooves  51  ( FIG. 6 ) located on the front and each side of the lower assembly  3 . Resistance bands of various sizes and resistance levels may be inserted into the U-grooves  51 . In an example, the upper surface of rotary discs  4  mate with the inner surface of the upper assembly  2  such that U-grooves  51  are effectively closed into curved lumens when the upper assembly  2  ( FIG. 28 ) is in the closed locked position. In this position, exercise media threaded into U-grooves  51  are locked into the exercise apparatus. 
     T-channels  52  ( FIG. 5 ) allow for connection of linear open end resistance bands by use of T-channel adapters  9 , described below. 
     An example of lower assembly  3  includes a storage compartment  32  which may be used to store, for example, T-channel adapters  9 . Furthermore, an example may include a storage compartment  31  which may be used to store, for example, a variety of resistance media such as that depicted by way of example in  FIG. 17 . 
     In an example, lower assembly  3  may be provided with a handle  12  as a convenient means for holding the exercise apparatus during transport from one location to another. Handle  12  may be secured to lower assembly  3  ( FIG. 9 ) by mounting rails  65  ( FIG. 9 ) positioned at the sides of the lower assembly  3 . In addition to being configured for securing handle  12  to lower assembly  3 , mounting rails  65  ( FIG. 9 ) are configured to allow handle  12  to move between extended and retracted positions relative to the front of upper  2  and lower  3  assemblies. The handle  12  may be placed in the retracted position, as demonstrated in  FIG. 1 , while the exercise apparatus is in use or prepared for storage. 
     In an example, handle  12  further comprises an accessory storage compartment  10  ( FIG. 11 ) configured to store, for example, an exercise bar  13  (described below). Handle door  61  may be used to secure exercise bar  13  in storage compartment  10 . Handle door  61  moves between up (closed) and down (open) positions relative to the top of handle  12 . With door  61  is in the open position, storage compartment  10  is exposed allowing for insertion or removal of an item such as exercise bar  13 . When handle door  61  is in the closed position, storage compartment  10  is covered allowing the exercise bar  13  to be securely stored. 
     As illustrated in  FIGS. 1-3  upper assembly  2  may be multi-functional and comprise eight glide rollers  25 . In an example, four guide rollers  25  may be provided at the front and two on each side of upper assembly  2 . Glide roller assemblies  25  are configured to spin around axes parallel to the outer surface of upper assembly  2  to reduce friction exerted on resistance media  1 ,  2 ,  3  and  4  ( FIG. 17 ) held within U-grooves  51  thereby increasing the life of the resistance media. 
     Glide rollers  25  are positioned to align with U-grooves  51  when upper  2  and lower  3  assemblies are closed ( FIG. 1 ). While a rotary disc  4  is positioned at 0 degrees in relation to the front of the exercise apparatus, the U-grooves  51  align with the four front glide rollers  25  as seen in  FIG. 1 . When a disc  4  is positioned at 90 degrees in relation to the front of the exercise apparatus, U-grooves  51  align with the glide rollers  25  common to its respective side. 
     During an example use of an exercise device including rollers  25  ( FIGS. 18-27 ), as exercise media such as resistance band  40  ( FIG. 6 ) moves over glide roller assemblies  25  assemblies  25  turn in a direction opposing the stress being applied to the media. 
     For example, if a resistance band is being pulled and stress applied in an upward direction in relation to the exercise apparatus, glide rollers  25  engaged by the resistance band turn in a counter clockwise direction. When tension is released and the band retracts rollers  25  turns in a clockwise direction reducing the friction between the band and exercise apparatus. 
     Glide rollers  25  may be made of a variety of lightweight, high strength materials including but not limited to metal, metal alloy, plastic or ceramic. 
     When locked in a closed position as shown by example in  FIG. 1 , upper assembly  2  prevents resistance media threaded into U-grooves  51  ( FIG. 6 ) from coming out of the channels by closing off the top of the U-grooves  51 . Upper assembly  2  also serves to secure adapters coupled with T-channels  52  ( FIG. 7 ) by closing off the top of the T-channel, when the exercise apparatus is locked in the closed position. It is noted that the terms “U” and “T” designate example configurations and other configurations are also possible as will be understood by those having ordinary skill in the art after becoming familiar with the teachings herein. 
     In an example, upper assembly  2  may be provided with accessory storage compartments  20 ,  21 ,  22  and  23 . Compartments may be used to store a variety of accessories. For example, storage compartments  20  may be used to store carabineers  16  ( FIG. 4 ), storage compartments  21  and  22  may be used to store multi-band adapters  7  and  8  ( FIG. 4 ) and storage compartments  23  may be used to store hand bars  14  ( FIG. 4 ). Upper assembly  2  may serve to safeguard resistance media and accessories stored in storage compartments  20 ,  21 ,  22 ,  23 ,  31  and  32  when the latch  5  locks upper  2  and lower  3  assemblies against pivoting. 
     Furthermore, the T-channels  24  may be provided on the front and sides of upper assembly  2  to enable attachment of accessories using T-channel adapters  9 . 
     The exercise apparatus is configured to enable use with a variety of exercise apparatus accessory devices. Accessory devices may include but are not limited to hand bars  14 , hand pads  17 , linear resistance bands  40  with closed loop connectors  41 , carabineers  16 , exercise bar  13 , and T-channel adapters  9 . 
     Through use of the accessory devices, users may quickly change apparatuses as well as resistance levels to perform a variety of different exercises. Accessory devices may be constructed of any of a variety of non-corrosive, light weight materials including but not limited to metal such as stainless steel or aluminum or plastic. Many exercises accomplished with free weights or more popular stationary apparatuses may be accomplished through use of the exercise apparatus with accessory devices. 
     With reference to  FIG. 4 , a T-channel adapter  9  may be coupled with a carabineer  16  and a rotary disc  4  to enable use of resistance media including closed loop connectors on both ends, for example, resistance bands  2  and metal tension springs  6 . In an example assembly, a T-channel adapter  9  is inserted into the T-channels  52  ( FIG. 5 ), a carabineer  16  is coupled between closed loop end  9   a  of T-channel adapter  9  and closed loop connector  41  of the resistance device  40  to secure the media to the exercise apparatus. T-channel adapters  9  may also be used to attach an optional harness ( FIG. 12 ) enabling wearing of the exercise apparatus as a backpack and accommodating a variety of upper body exercises. As mentioned above, T-channel adapters  9  may be stored in storage compartment  32  when not in use. 
     With multi-band adapters  7  and  8  illustrated by way of example in  FIG. 4 , many commonly available resistance bands and tension springs types may be used with an example of the disclosed exercise apparatus. In an example, a multi-band adapter comprises a male adapter  8  and a female adapter  7 . 
     Male adapter  8  is configured to mate with T-channels  52  ( FIG. 7 ). T-channels  52  are configured to receive extension  8   a  of the male adapter  8  ( FIG. 7 ). 
     A small closed loop  7   a  on top of female adapter  7  may be used to securely attach accessory devices to the exercise apparatus by coupling carabineer  16  to closed loop connector  7   a  at the top of the female adapter  7 . 
     The open loops  8   b  and  7   b  on the bottom of the male  8  and female  7  adapters are used to facilitate a variety of resistance levels.  FIG. 16  illustrates a variety of possible configurations for resistance media held by open loops  8   b  and  7   b.    
     Resistance media having hook connectors, such as resistances bands  1  and tension springs  5 , ( FIG. 17 ) may be secured to male  8  or female  7  multi-band adapter eyelets by clipping hook  42  ( FIG. 7 ) to one of the four eyelets  8   b  or  7   b  located at the bottom of the male adapter  8  or female adapter  7 . 
     Resistance media having closed loop connectors, such as circular closed loop resistance bands  4  and linear resistance devices  2  and  6  ( FIG. 17 ) may be secured to the male and female multi-band adapters by pinching the resistance media  40  between the thumb and index finger with hands approximately one inch apart while moving the hands apart ( FIG. 14 ). As the hands move apart the diameter of the elastic band between the fingers begins to narrow. When the diameter of media  40  is smaller than the adapters eyelet opening the narrow portion of the media may be inserted through the desired eyelet opening  8   b  or  7   b  and the resistance media may be released. Upon release, the diameter of resistance band  40  increases to a size larger than the opening of the eyelet. The resistance band may thereby be secured during exercise. To remove or reposition resistance media  40  these steps may simply be reversed for each corresponding eyelet. 
     Linear flat resistance bands  3  ( FIG. 17 ) may be tied together at both ends to create a closed loop configuration. Male  7  and female  8  adapters, when used with common resistance media such as resistance bands and tension springs, allow users to quickly change resistance levels in a variety of configurations as illustrated in ( FIG. 16 ). Illustrations  1  thru  4  ( FIG. 16 ) depict configurations of a single linear resistance band offering a corresponding variety of resistance levels. Illustrations  5  thru  8  ( FIG. 16 ) depict configurations of two linear resistance bands offering a variety of resistance levels. Illustrations  9  thru  11  of ( FIG. 16 ) depict configurations of closed loop and flat resistance bands corresponding with variable resistance levels. 
     An exercise bar  13 , configured to simulate a barbell frequently used with free weights may be a fixed length or telescoping variable length bar allowing the exercise apparatus to replicate many exercises typically performed with free weights or on more popular stationary apparatuses. 
     Hand bars  14  configured to simulate dumbbells used with free weights may be used individually or in pairs, with one in each hand. As with exercise bar  13 , hand bars  14  allow users to replicate many exercises typically performed with free weights or on more popular stationary apparatuses. 
     In an example, the exercise apparatus may also provide hand pads  17  and foot straps ( FIG. 13 ). The hand pads may be formed of densely padded, durable nylon webbing, wrap around the circumference of the horizontal bar at the top of the hand bars  14  to reduce impact of stress or tension exerted on a user&#39;s hands while performing exercises. 
     In an example, foot straps  47  ( FIG. 13 ) may be provided with connectors  45  and  49  which configure to enable securing the device to the foot and provide a means of attaching accessories devices usable with the exercise apparatus. With connector  49 , strap  47  may be adjusted for comfort and the foot strap may be secured to a foot of a user for exercise. Connector  45  may be a closed loop connector configured for attaching accessories usable with the exercise apparatus.  FIG. 13  demonstrates an example technique of attaching a female multi band adapter  7  to a closed loop connector  45  using carabineer  16  to secure the female adapter  7  to the foot strap. Foot straps may be constructed of any of a variety of materials including but not limited to durable nylon. 
     The resistance media used in conjunction with each other may be configured to perform a variety of exercises external to the exercise apparatus. As an example, utilizing the two female multi-band adapters  7  in conjunction with two carabineers  16  and two hand bars  14  as shown in  FIG. 8 , the configuration can simulate a chest expander that when used in conjunction with the resistance devices illustrated in  FIG. 17  can be configured as outlined in  1  thru  12  of  FIG. 16  independently from the exercise apparatus. 
     Carabineers  16  may be used to attach resistance media or connectors that are too large to be inserted through the male or female adapter eyelet openings  8   b  and  7   b . Other examples of the male  8  and female  7  multi-band adapters may be configured with either larger or smaller eyelets or eyelet openings to accommodate larger or smaller resistance bands or connector types. 
     A harness assembly, illustrated by way of example in  FIG. 12 , may include lightly padded shoulder straps  38  and chest straps  39  for comfort and hook connectors  42  to allow the exercise apparatus to be attached and worn like a backpack. Shoulder straps  38  and chest straps  39  may be adjusted for comfort using slide adjusters  43 , thus accommodating users of different size or stature. While wearing the exercise apparatus like a backpack, a user may either sit or stand and perform a variety of exercises such as those depicted in  FIGS. 25-27 . A harness may be constructed of any of a variety of suitable materials including but not limited to durable nylon. 
     In an exercise apparatus illustrated by way of example in  FIG. 28 , rotary discs  4  may be eliminated. Rotary discs  4  may be, for example, replaced by a solid lower platform  3  with U-grooves  51  and T-channels  52  placed at 0, 90, and 270 degrees when viewed from the front of the exercise apparatus. In some examples, U-channels  51  and T-grooves  52  may be provided at angles other than these. 
     T-channels  52  are configured to offer the same use described with reference to an example including rotary discs  4 . In an example provided with a solid platform, a user may unlock the fronts of upper  2  and lower  3  assemblies and pivot the assemblies to open the exercise apparatus before moving exercise media from one U-channel or T-groove to another U-channel or T-groove. 
     The example exercise device shown in  FIG. 28  may be carried like a book or laptop computer. Resistance devices and associated accessories can be stored externally from the apparatus by other means. 
     Before continuing, it should be noted that the examples described above are provided for purposes of illustration, and are not intended to be limiting. Other devices and/or device configurations may be utilized to carry out the operations described herein. 
     An exercise apparatus may be prepared for travel or storage by placing the associated resistance media and accessories into designated storage compartments, closing the lid and sliding the latch  5  to the locked position. 
     In an example, the apparatus may be about the size of a standard laptop computer and may be easily packed in a suitcase, briefcase, carried in a standard laptop bag or transported utilizing a carrying handle incorporated into the apparatus. In an example, the exercise apparatus may also incorporate an optional carrying case or shoulder bag conforming to the contour of the exercise apparatus and including storage compartments to accommodate resistance and accessories devices when not in use. 
     The operations shown and described herein are provided to illustrate example implementations. It is noted that the operations are not limited to the ordering shown. Still other operations may also be implemented. 
     As mentioned, an exercise apparatus may be used to practice a variety of exercises. According to a method of using the apparatus depicted by way of example in  FIG. 29 , starting with the exercise apparatus in a closed configuration in step S 1010 , a user desiring to exercise pivots the upper  2  and lower  3  assemblies relative to one another about the axis of connecting rod  34  to reveal U-grooves. An example including a locking mechanism, may require latch  5  be slid to allow for opening of the exercise apparatus. 
     The user then provides one or more resistance media to the U-grooves in step S 1020 . In an example including storage compartments within upper  2  and/or lower  3  assemblies, the user may provide the resistance media from the storage compartments. In an example not including rotary discs, the user will choose which sets of U-grooves are appropriate for the exercise he or she would like to perform. For example, the user may select to use the U-grooves on the left and right sides of the exercise apparatus, the U-grooves on the front of the exercise apparatus or a combination of these. After providing the chosen exercise media to the selected U-grooves, the user may close the exercise apparatus to close the top of U-grooves against upper assembly  2 . 
     In an example including rotary discs, the user need not select the orientation of the U-grooves before closing the exercise device since rotary discs are capable of rotation while the upper  2  and lower  3  assemblies are closed. Rotation of rotary discs effectively rotates the U-grooves. 
     With the exercise media coupled with the U-grooves, the user may perform exercise by pulling the coupled exercise media from a contracted position to a stretched position in step S 1030 . 
     During some exercises the user may be seated on a top surface of the upper assembly while pulling the coupled exercise media from a contracted position to a stretched position. Examples of seated exercises are illustrated in  FIGS. 18-20 . As shown in  FIG. 18 , with his or her upper arms approximately parallel with the frontal plane the user flexes his or her arms at the elbows. As shown in  FIG. 19 , with his or her arms extended at the elbows, the user abducts his or her arms at the shoulders. As shown in  FIG. 20 , a user may extend his or her arms at the elbows and abduct the two arms at their respective shoulders from a position with hands near ears of a user to a position above the head of the user. 
     With an example including a foot harness, after coupling the foot harness to his or her foot, a user, while seated, may exercise by flexing one leg at the hip and extending the leg at the knee to pull exercise media from the contracted position to the stretched position as shown in  FIG. 21 . 
     During some exercises, the user may stand on the top surface of upper assembly  2  while pulling the coupled exercise media from a contracted position to a stretched position. Examples of standing exercises are illustrated in  FIGS. 22 and 23 . As shown in  FIG. 22 , a user may abduct his or her arms at the shoulders from an approximately vertical position to an approximately horizontal position. As shown in  FIG. 23 , a user may extend his or her arms at the shoulders approximately 180 degrees from an approximately vertical position. As shown in  FIG. 24 , from a kneeling position a user may extend his or her arms at their respective elbows and abduct the arms at the shoulders from a position with hands near ears of a user to a position above the head of a user. 
     Because rotary discs are capable of rotation without opening the exercise device, in an example including the rotary discs, the user may remain seated or standing on the exercise device and adjust the orientation of the rotary discs in step S 1040  to perform a different exercise in a step S 1050 . The user may use this feature to perform a variety of exercises consecutively without opening the upper  2  and lower  3  assemblies. 
     With an example including a harness as shown in  FIG. 12 , after coupling the harness to upper assembly  2 , the user may also couple the harness to his or her torso, using straps  38  and  39  with adjusters  43 . As such, the exercise apparatus will be held to the back of the user to allow the user to perform exercises such as those illustrated in  FIGS. 25-27 . As shown in  FIG. 25 , with the exercise device worn as a backpack, the user may extend his or her arms at the elbows and abduct his or her arms at the shoulders from a position with hands near ears of a user to a position above the head of a user. As shown in  FIG. 26 , with the exercise device worn as a backpack and the user&#39;s arms flexed within a transverse plane, the user may extend his or her arms at the elbows and rotate his or her arms at the shoulders from a position with hands near the side of the user to a position with hands in a plane shared with the shoulders in front of the user. As shown in  FIG. 27 , with the exercise device worn as a backpack, the user may move his or her arms from a position within a frontal plane to a position where each arm lies within a parasagittal plane. 
     It is noted that the exercises for which the present disclosure may be used, are not limited to those explicitly shown or described. Furthermore, the examples shown and described are provided for purposes of illustration and are not intended to be limiting. Still other examples are also contemplated.
