TECHNICAL FIELD

[0002] The present invention relates generally to strength training and exercise equipment.

BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS POSED BY THE PRIOR ART

[0003] Strength training and exercise equipment is useful for maintenance of personal fitness and good health. Strength training and exercise equipment in the prior art include dumbbells, barbells, exercise benches, squat racks, weight machines, treadmills, stair climbers, stationary bicycles, stretch cords, resistance bands, exercise belts and vests, the TRX system, and the like. Strength training and exercise equipment has been useful and popular in fitness centers, physical therapy centers, and residences. While they are popular, fitness centers and physical therapy centers have drawbacks including internal operating costs, membership and user fees, and the need for large spaces for setting up multiple pieces of equipment that are large, heavy, and immobile. Also, users must travel to fitness centers and physical therapy centers which may be timeconsuming and logistically challenging for some users including those needing assistance or using mobility equipment such walkers and wheelchairs.

[0004] Strength training and exercise equipment in residences, such as family homes and apartment buildings, provide advantages including convenient in-home use, the ability of users to choose which equipment to buy and set up at home, and lower cost compared to fitness center memberships and physical therapy fees. However, in-home strength training and exercise equipment is often large, heavy, and immobile, and users are often constrained by limited space and budget.

[0005] To address the disadvantages of the above-described strength training and exercise equipment and use of such equipment in fitness centers, physical therapy centers, and residences, there is a need for such equipment that is inexpensive, lightweight, takes up little space, easily used indoors or outdoors, and enables the user to perform a wide variety of strength training exercises, at varying levels of exertion, in various upright, seated or horizontal positions, and while stationary or in motion. Prior art attempts at designing equipment that attempts to achieve some of these advantages, but falling short in numerous ways, include a variety of wearable exercise belts, vests, suits and the like. For example, see U.S. Patent Nos. 5372565, 5813955, 6691318, 7707652, 7998041 , 8443465, 8968166, and 9724554 and U.S. Patent Publication Nos. US20030125170A1 , US20050282689A1 , US20060040805A1 , US20070015640A1 , and US20070219074A1 . Such prior art attempts to design equipment to achieve such advantages have not proven useful or successful. Drawbacks appear to include limited functionality and utility, complications of design, and clumsiness in use.

[0006] To address the limitations of the above-referenced strength training and exercise equipment, the inventor herein has developed a new system of exercise equipment and associated methods of use. The equipment developed by the inventor and described in detail below includes a simple, lightweight, easy-to-use piece of wearable equipment and associated accessories that enable the user to perform a wide variety of strength training exercises without needing equipment normally found in a fitness center or physical therapy center. The equipment described herein includes a wearable vest having strategically located connection points, such as loops or rings, for attaching stretch cords of varying lengths. The ends of the stretch cords have connectors such as carabiner clips that can hook onto the connection points on the vest on one end of the cord and, at the other end of the cord, can attach to loops on handles, bars, arm straps, leg straps, foot straps, etc. for engagement of the user’s hands and feet. The connection points on the vest are strategically placed to enable performing a wide variety of strength training exercises while the user is pulling or pushing on the ends of the stretch cords. Further, the vest is adjustable to obtain a snug, non-slipping fit on the user. Additional features include pockets on the vest for holding weighted bags or inserts or for storing stretch cords, water bottles, etc. A detachable backpack and other accessories and features are shown in the drawings and discussed in the detailed description below.

[0012] In one preferred form of the present invention, the exercise system includes three pairs of stretch cords wherein the first pair is in the range of about six inches (152 mm) to about 9 inches (229 mm) in length in a resting condition, the second pair is in the range of about eight inches (203 mm) to about thirteen inches (330 mm) in length in a resting condition, and the third pair is in the range of about fourteen inches (355 mm) to about twenty-two inches (559 mm) in length in a resting condition.

[0013] According to another preferred form of the present invention, the exercise system includes three pairs of stretch cords wherein the first pair is in the range of about four inches (102 mm) to about twelve inches (305 mm) in length in a resting condition, the second pair is in the range of about six inches (152 mm) to about fourteen inches (355 mm) in length in a resting condition, and the third pair is in the range of about sixteen inches (406 mm) to about twenty-eight inches (711 mm) in length in a resting condition. Preferably, the first pair of stretch cords are stretchable to a length of approximately twenty-two inches (559 mm) to approximately twenty-six inches (660 mm), the second pair of stretch cords are stretchable to a length of approximately thirty-two inches (813 mm) to approximately forty inches (1016 mm), and the third pair of stretch cords are stretchable to a length of up to seventy inches (1 ,778 mm).

[0014] In yet another preferred form of the present invention, the exercise system includes elastic material on the sides of the vest for permitting stretching and enhancing a snug fit for a user. [0015] In one alternative form of the present invention, the reclosable hooks have a triangular shape.

[0016] In one preferred form of the present invention, the exercise system further includes a forearm sleeve for wrapping around a user’s forearm and having one or more loops for engaging at least one hook on at least one stretch cord.

[0017] In another preferred form of the present invention, the exercise system further includes a knee sleeve for wrapping around a user’s knee and having one or more loops for engaging at least one hook on at least one stretch cord.

[0018] In another preferred form of the invention, the tension or length on the cords may be adjusted, such as by changing the strength resistance or length of the cords. In a preferred embodiment, the strength resistance or length of the cords can be adjusted by changing the cords to different cords.

[0019] According to still another broad form of the present invention, a method of using an exercise system is provided. The method includes the step of obtaining an exercise system including an openable and reclosable vest having closing means to secure the vest in a closed condition, and a plurality of loops located on the surface of the vest. The exercise system includes at least one stretch cord having two ends, at least one end having an openable and reclosable attachment means for being removably attached to one of the plurality of loops on the vest. The exercise system includes at least one handle operatively connected to the other end of the stretch cord. The plurality of loops on the vest are configured at various locations on the vest to permit a variety of exercises by pulling or pushing the at least one stretch cord in multiple directions. The method of use includes the steps of wearing the vest and attaching one end of the stretch cord to at least one of the loops on the vest. The method includes the further step of pulling the handle away from the vest to elongate the stretch cord.

[0020] In an alternative aspect and benefit of the method of use enabled by the invention, the user combines arm and leg exercises while stationary or in motion.

[0021] In an alternative aspect and benefit of the method of use enabled by the invention, the user can progressively change the resistance on the stretch cords during the course of a workout by either changing the stretch cords to different weights (different weights meaning different levels of stretch resistance, typically measured in pounds or kilograms) or by adding or subtracting the number of stretch cords attached to the handles or straps so as to multiply or reduce the amount of force needed to stretch the cords. In an alternative aspect and benefit of the method of use enabled by the invention, by changing connection points on the vest, handles and straps, the user can change the direction of movement of the hands, arms, legs and/or feet during the course of a workout so as to engage different muscles needed to move the handles and/or straps. Thus, in an alternative aspect and benefit of the method of use enabled by the invention, the user, during the course of a workout, can progressively change both the stretch cords and the connection points on the vest, handles or straps so as to change the amount, and/or direction of, resistance felt in the handles or straps (and therefore change the muscles being engaged by the user to move the handles or straps and/or the amount of exertion of the muscles). Various lengths and weights of cords may be easily carried in pockets in the vest during the course of a workout so as provide convenient access to the cords so that the user can change or add cords that are connected to the vest, handles and/or straps during the course of a workout. Thus, the combination of features of the invention enables a progressive strength training workout while stationary or in motion (such as during a walk, jog or run either on a track or on a course taking the user away from the starting point). It is believed that this system enables a new kind of progressive strength straining exercise while in motion so as to enable a new kind of workout combining strength training and cardio exercise at all levels of fitness of the user.

[0022] In an alternative aspect of the invention, weighted bags or other forms of weighted inserts may be inserted into the pockets on the front and/or back of the vest. Thus, during use of the vest, handles and straps, the weighted bags or inserts can change and/or enhance the workout by the user.

[0023] In an alternative and separate aspect of the invention, the vest includes a bracing member located at a rear portion of the vest wherein the vest functions as a back brace. Preferably, the bracing member is removably secured to the vest. More preferably, the bracing member is removably secured within a pocket located in a rear portion of the vest. In one preferred form, the pocket for retaining the bracing member has an arcuate, tapered configuration that tapers from a wider, zipper closable open end at the bottom of the vest to a narrower, closed end at the top of the vest. Preferably, the bracing member has an arcuate, tapered configuration that tapers from a wider bottom end to a narrower closed top end.

[0024] In this alternative form of a back brace embodiment of the invention, the vest is provided with a tightening strap located proximate to a geometric center of the bracing member. Preferably, the tightening strap on the vest located proximate to the center of the bracing member runs within a back portion of the vest such that the bracing member is located between a user’s spine and the tightening strap.

[0025] According to one preferred form of the back brace embodiment of the invention, the bracing member is a composite material with a rigid substrate portion facing away from a user of the vest and a compliant portion facing toward a user of the vest. Preferably, the rigid substrate portion is a rigid polymer, and the compliant portion is a closed cell foam.

[0026] In another preferred form of the back brace embodiment of the invention, the vest is provided with at least one anterior bracing member located at a front portion of the vest. Preferably, the anterior bracing member is removably secured to the vest, and more preferably, the anterior bracing member is secured in a pocket located in a front portion of the vest. The anterior bracing member preferably has a tapered configuration that tapers from a wider top end to a narrower bottom end.

[0027] According to another preferred form of the back brace embodiment of the invention, the anterior bracing member is a composite material with a rigid substrate portion facing away from a user of the vest and a compliant portion facing toward a user of the vest. Preferably, the rigid substrate portion is a rigid polymer, and the compliant portion is a closed cell foam.

[00142] Referring to Figs. 29-36, an alternative embodiment of the vest 1 of the present invention includes a back brace or bracing member 200 as illustrated in Figs. 29- 36. A female configured version of the vest 1 with bracing member 200, with an inwardly- curved shape is shown in Figs. 29, 30, 33, 35 and 36 and a male configured version of the vest 1 (without the inwardly-curved shape) is shown in Figs. 31 , 32 and 34.

[00143] In one embodiment of the back brace version of the vest, the bracing member 200 (shown removed from the vest in Figs. 37-38) has an ovoid or egg shape and defines a relatively wider bottom end 202 for being located proximate to the bottom of the vest 1 , and further defines a tapering, relatively narrower top end 204 for being located proximate to the top of the vest 1 . The bracing member may have other shapes and sizes as is well-known in the art. With reference to Fig. 35, the vest 1 may be provided with an additional tightening strap 4 or equivalent tightening means located near the center of the bracing member 200, and which functions to draw the bracing member 200 tight against the spine of the user. Preferably, the additional middle tightening strap 4 runs behind (posteriorly of) the bracing member 200 such that the brace member 200 is located between the strap 4 and the user’s spine, as illustrated in Figs. 35 and 36. The strap 4 is preferably located within layers of the rear portion of the vest material.

[00144] The bracing member 200 may be removably or non-removably attached to the rear panel or portion of the vest 1. For example, the bracing member 200 may be sewn into the rear portion of the vest 1. More preferably, the bracing member 200 has the form of an insert for being removably retained within a pocket 210 in contact with the back of a user as shown in Figs. 33 and 34. The pocket 210 has an open, wide bottom end 212 for receiving the bracing member 200 and a closed, tapered top end 214 to receive and locate the top end 204 of the bracing member 200. The pocket 210 includes means for closing the bottom end 212 such as a zipper 216. Other suitable means for closing the pocket 210 may be used, such as buttons, Velcro, snaps, magnets, clasps, etc.

[00145] The bracing member 200 is configured in each of the male and female vests 1 to reside only within the rear panel or portion of material and to support the spine and adjacent muscles during use of the vest 1 . Referring to Figs. 37-39, the bracing member 200 is preferably formed as a composite structure with a relatively more rigid substrate portion 220 facing away from a user’s back, and a relatively more compliant portion 224 facing the user’s back. In one presently preferred embodiment, the rigid substrate 220 is an acrylonitrile butadiene styrene (ABS) plastic sheet that may be thermoformed to the desired contour and the compliant portion 224 is a closed cell foam. The portions 220 and 224 of the composite are connected by an adhesive film layer. Other materials are contemplated for the bracing member 200, such as metal or other thermoplastics for the rigid substrate portion 220. Furthermore, the compliant portion 224 of the bracing member 200 could be formed from cloth, padding, textile, or open cell foams. In one form, the bracing member 200 may have a plurality of through holes or apertures 228 to reduce its weight and improve breathability. The bracing member 200 functions to provide back and spine support during exercise, and thereby assists in maintaining good posture and alignment of the spine during exercise. [00146] Referring to Figs. 40-43, an anterior brace or anterior bracing member 300 is illustrated, which may be removably or non-removably attached to a front portion or panel of the vest 1 . The anterior bracing member 300 (shown removed from the vest 1 in Figs. 40-43) has tapered, curved shape, and defines a relatively wider top end 302 for being located proximate to the top of the vest 1 , and further defines a relatively narrower bottom end 304 for being located proximate to the bottom of the vest 1 .

[00147] The anterior bracing member 300 is configured to be provided as a pair of inserts for insertion into the front pockets 7 of the vest 1 . Alternatively, the anterior bracing members 300 may be non-removably attached to the right and left sides of the front panel or portion of the vest 1. For example, the anterior bracing members 300 may be sewn into the front portions of the vest 1 (see Figs. 1 and 2). The anterior bracing members 300 are configured to support the chest and adjacent muscles during use of the vest 1 . Each anterior bracing member 300 is preferably formed as a composite structure with a relatively more rigid substrate portion 320 facing away from a user’s chest, and a relatively more compliant portion 324 facing the user’s chest. In one presently preferred embodiment, the rigid substrate 320 is an acrylonitrile butadiene styrene (ABS) plastic sheet that may be thermoformed to the desired contour and the compliant portion 324 is a closed cell foam. The portions 320 and 324 of the composite are connected by an adhesive film layer. Other materials are contemplated for the anterior brace member 300, such as metal or other thermoplastics for the rigid substrate portion 320. Furthermore, the compliant portion 324 of the anterior bracing member 300 can be formed from cloth, padding, textile, or open cell foams. In one form, the anterior bracing member 300 may have a plurality of through holes or apertures 328 to reduce its weight and improve breathability. The comers of the anterior bracing member 300 are rounded for improved comfort of the user and ease of insertion into the vest 1 .

[00148] In one presently preferred form of the invention, each anterior bracing member 300 includes a top end 302 of about 3.75 inches (95 mm), a bottom end 304 of about 3.25 inches (83 mm), and an overall height of about 9 inches (229 mm). Preferably the compliant portion 324 has a thickness of about 1/8 inch (3.2 mm). [00149] Referring to Figs. 44-47, a wrist or forearm sleeve attachment 350 is shown for being wrapped around a user’s forearm or wrist. The forearm sleeve 350 is advantageous for users of the invention that cannot grip a handle attached to a stretch cord (e.g., 40 in Figs. 5-7) such as is the case for amputees, stroke victims, arthritis, and other disabilities or conditions. The forearm sleeve 350 may have one or more connection points or loops at various locations for engagement with a stretch cord 40 that extends from the vest to the forearm sleeve 350. Preferably, there are two loops 351 located proximate the top and bottom ends on the left side of the sleeve 350, two loops 352 located proximate the top and bottom ends on the right side of the sleeve 350, and two loops 353 located proximate the top and bottom ends on the middle of the sleeve 350. The sleeve 350 may have one or more tightening straps, belts, Velcro straps or other similar connection to hold the sleeve 350 snugly and securely around the arm. The available choices for the design, construction and materials for the sleeve 350 are known to those of ordinary skill in the art. The sleeve 350 preferably has two tightening straps 354 that are fastened with Velcro to secure the sleeve 350 around the user’s forearm.

[00150] Referring to Figs. 48-51 , a knee sleeve attachment 360 is shown for being wrapped around a user’s knee. The knee sleeve 360 is advantageous for users of the invention that cannot utilize a foot strap (e.g., 70 in Figs. 9a and 9b) such as is the case for amputees, diabetes, arthritis, and users having other disabilities or conditions. The knee sleeve 360 may have one or more connection points or loops at various locations for engagement with a stretch cord 40 that extends from the vest 1 to the knee sleeve 360. Preferably, there are two loops 361 located proximate the top and bottom ends on the right side of the knee sleeve 360, two loops 362 located proximate the top and bottom ends on the left side of the knee sleeve 360, and two loops 363 located proximate the top and bottom ends on the middle of the knee sleeve 360. The knee sleeve 360 may have one or more tightening straps 370, belts, Velcro straps or other similar connection to hold the sleeve 350 snugly and securely around the leg proximate the user’s knee. The available choices for the design, construction and materials for the sleeve 360 are known to those of ordinary skill in the art. The knee sleeve 360 preferably has a front aperture 372 and rear aperture 374 to accommodate bending of the knee during use of the sleeve 360. [00151] With reference now to Figs. 52-57, the inventor has found that the connection of multiple stretch cords extending from the same attachment (e.g., handle 44, foot strap 70, wrist sleeve 350, knee sleeve 360, etc.) to different attachment points or loops 8a-8j on the vest 1 can present novel exercises for multiple muscle groups during the range of motion of a user. The cords may be of different lengths and strength resistances to vary the degree of resistance and range of motion provided by stretch cords during use. Fig. 52 illustrates a configuration of the vest 1 with a hand grip 44 attached by two different cords to loops 8d and 8h and having an increased resistance compared to the use of a single cord connected to a single loop and further providing additional resistance in a greater range of motion in both upward and downward directions as the user moves his or her arms up and down. Fig. 53 illustrates a configuration of the vest 1 with a hand grip 44 attached to loops 8e and 8f by two different cords for an increased resistance arm curl, and further illustrates a foot strap 70 attached to loops 8b and 8c by two different cords for an increased resistance leg extension or squat exercise. In contrast, Fig. 54 illustrates a pair of foot straps 70 attached, at different points 72 and 73, to cords connected to the lower loops on the vest 1 for a different increased resistance leg extension or squat exercise. Fig. 55 illustrates the use of the two rear loops 8i and 8j connecting pairs of cords to a pair of knee sleeves 360 and a pair of foot straps 70 to permit resistance with any lower leg movement of a user. Fig. 56 illustrates a user wearing a forearm sleeve 350 connected to two side loops 8d and 8d for a hands free resistance with all arm movements. Fig. 57 illustrates a combination exercise using a forearm sleeve 350 and a hand grip 44, wherein three separate loops 8g, 8a, 8b are utilized on the vest 1 . It will be apparent to one skilled in the art that a multitude of other multi-point exercises are possible with the vest 1 and one or more attachments.

[00152] The exercise system and method of use of the vest 1 and accessories disclosed herein include a user putting on and wearing the vest 1 . The user chooses the length of stretch cord(s), the resistance strength of the stretch cords, and whether to double the stretch cords for added resistance, depending on the exercise(s) to be done. For example, for exercises using connections to the shoulder loops 8g and 8h or lower loops 8c and 8f on the vest, the user might choose stretch cords 50 having unstressed or resting lengths in the range of around four inches (102 mm) to around fourteen inches (355 mm) to perform arm exercises wherein the arm is straightened. In one preferred embodiment, cords of about eight inches (203 mm) lengths are used. See, for example, Fig. 17a, Fig. 17g, Fig. 17i, Fig. 17j, Fig. 17o and Fig. 17p where shorter cords may be preferred, and see Fig. 17e, 17k, Fig. 171, and Fig. 17m where medium length cords may be use. The shorter cords, such as the six inch (152 mm) cords, seven inch (178 mm) cords, eight inch (203 mm) or nine inch (229 mm) cords, are preferable for the exercises requiring less extension, such as shoulder presses, chest presses, and the like. For performing biceps curls, the user can choose a shorter cord, i.e. , a stretch cord having a length around six inches (152 mm), seven inches (178 mm), or eight inches (203 mm) and attach it to a lower front loop on the vest. For exercises using a foot bar 75 or foot straps 70, the user can choose a longer stretch cord having a length in the range of around sixteen inches (406 mm) to twenty-eight inches (711 mm). In one preferred embodiment, eighteen inch (457 mm) lengths are used. See, for example, the exercises illustrated in Fig. 17b, Fig. 17c, Fig. 17f, Fig. 17h and Fig. 17n. For exercises using the thigh straps, such as the kneeling fire hydrant exercise or the clamshell exercise, the user might choose the shorter stretch cords in the range of eight inches (203 mm) to fourteen inches (355 mm). Optimal lengths of the stretch cords may depend on the size of the user and the length of his or her limbs.

[00153] After choosing the stretch cords, then, depending on the exercise to be done, the user might choose any combination of handles (see choices in Figs. 6, 7, 7a and 8), foot straps (see Figs. 9a and 9b), bars (see choices in Figs. 10-13) thigh straps (see Fig. 14), forearm straps (see Figs. 44-47) and knee straps (see Figs. 48-51 ). The user may then perform the exercise. The various combinations of the vest, stretch cords, foot straps, thigh straps, knee straps, handles and bars enable user to choose from a wide variety of exercises as discussed above and shown in Fig. 17a through Fig. 17p, as well as many other exercises not shown.

[00154] The above-disclosed exercise equipment and system, and associated methods of use thereof, enables the user to perform a wide variety of exercises without the need for extensive equipment normally seen in fitness centers, physical rehabilitation centers, residences, and the like. The disclosed system advantageously uses the human body as an anchor for stretch cord exercises wherein there is no need for attachment of the ends of the stretch cords to external anchors. Such exercise equipment and associated system and many of the associated methods and exercises do not use gravitational forces, and can be used and done in a weightless environment. Using the disclosed vest, equipment, and stretch cord system, the vest can be worn, the equipment used, and exercises performed while sitting, standing, lying down, walking or running, indoors or outdoors, and while stationary or moving. The disclosed system is useful to persons with impairments in strength or mobility, including wheelchair-bound persons, performing numerous strength training exercises. The thigh strap, forearm strap and knee strap embodiments are useful to amputees of hands, feet or lower legs for performing a variety of strength training exercises. Unlike carrying and using weights, such as dumbbells, while walking or running, the disclosed system enables the ability to combine resistance training such as performing arm exercises using the vest and stretch cords, while simultaneously walking or running, without significant weight to be borne by the lower extremities. Since the various sets of stretch cords are quite lightweight, they can be carried in a storage pocket during a stationary or moving workout (e.g. while walking or running). At any time during a workout, the choice and configuration of the stretch cords can be changed so as to add or subtract resistance force on the handles while stationary or in motion. Thus, the invention enables a dynamic and progressive resistance training method of use, while in motion and combination with cardio training, along a pathway.

[00155] For example, in the method of use enabled by the invention, the user can progressively change the resistance on the stretch cords during the course of a workout by either changing the stretch cords to different weights (different weights meaning different levels of stretch resistance, typically measured in pounds or kilograms) or by adding or subtracting the number of stretch cords attached to the handles or straps so as to multiply or reduce the amount of force needed to stretch the cords. In an alternative aspect and benefit of the method of use enabled by the invention, by changing connection points on the vest, handles and straps, the user can change the direction of movement of the hands, arms, legs and/or feet during the course of a workout so as to engage different muscles needed to move the handles and/or straps. Thus, in an alternative aspect and benefit of the method of use enabled by the invention, the user, during the course of a workout, can progressively change both the stretch cords and the connection points on the vest, handles or straps so as to change the amount, and/or direction of, resistance felt in the handles or straps (and therefore change the muscles being engaged by the user to move the handles or straps and/or the amount of exertion of the muscles). Various lengths and weights of cords may be easily carried in pockets in the vest during the course of a workout so as provide convenient access to the cords so that the user can change or add cords that are connected to the vest, handles and/or straps during the course of a workout. Thus, the combination of features of the invention enables a progressive strength training workout while stationary or in motion (such as during a walk, jog or run either on a track or on a course taking the user away from the starting point). It is believed that this system enables a new kind of progressive strength straining exercise while in motion so as to enable a new kind of workout combining strength training and cardio exercise at all levels of fitness of the user.

[00156] In an alternative aspect of the invention, weighted bags or inserted may be added to the pockets on the front and/or back of the vest. Thus, during use of the vest, handles and straps, weighted bags or inserts can change and/or enhance the workout by the user.

[00157] Because the disclosed vest, stretch cords, handles and various bars are lightweight and take up little space, they are portable and easily transported in a car, on an airplane, etc., and they usable at any chosen location (such as other residences or hotel rooms). The disclosed equipment and system can be set up and the disclosed methods of use performed in any location with minimal set-up effort. The disclosed equipment, system and associated methods of use avoid drawbacks associated with other kinds of fitness equipment including high cost, needing multiple pieces of heavy and cumbersome equipment, large space requirements, lack of portability, and lack of utility in terms of the variety of exercises that can be done with a single piece, or very few pieces, of equipment. The disclosed equipment, system and methods of use are unknown in the prior art and are believed to be a quantum leap in the state of the art in training and exercise equipment and associated systems and methods of use. [00158] While the preferred embodiment of the invention includes attachment means between components (stretch cords, vest loops, handles) in the form of carabiner type openable and closable hooks, it will be understood that other attachment means may be utilized. For example, the stretch cords could be tied to, or threaded through, the vest or hand grips, Velcro or snap-fit connections may be use, and other functionally equivalent mechanisms may be used.
