[Priority]
This application claims priority from U.S. Provisional Patent Application No. 63/297,933, filed January 10, 2022, U.S. Provisional Patent Application No. 63/329,395, filed April 9, 2022, and U.S. Provisional Patent Application No. 63/426,409, filed November 18, 2022, the entire contents of which are incorporated by reference into this specification.

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

Strength training and exercise equipment is useful for maintaining an individual's strength and health. Prior art strength training and exercise equipment includes dumbbells, barbells, exercise benches, squat racks, weight machines, treadmills, stair climbers, stationary bikes, stretch cords, resistance bands, exercise belts and vests, TRX systems, and the like. Strength training and exercise equipment is useful and popular in fitness centers, physical therapy centers, and homes. Despite their popularity, fitness centers and physical therapy centers suffer from drawbacks including internal operating costs, membership fees and usage fees, and the need for large spaces to accommodate multiple pieces of equipment that are large, heavy, and immovable. Users must also travel to fitness centers and physical therapy centers, which is time consuming and can create mobility challenges for some users, including those who require assistance or use mobility devices such as walkers and wheelchairs.

Strength training and exercise equipment in residential buildings, such as family homes and apartment complexes, offers advantages including convenience for in-home use, user choice of equipment to purchase and install in the home, and low 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 budgets.

To address the disadvantages of the strength training and exercise equipment described above and the use of such equipment in fitness centers, physical therapy centers, and homes, there is a need for equipment that is inexpensive, lightweight, takes up little space, is easily used indoors or outdoors, and allows a user to perform a variety of strength training exercises at various levels of activity, in various standing, sitting, or lying positions, while stationary or moving. Prior art attempts to design equipment to attempt to achieve some of these advantages include various wearable exercise belts, vests, suits, and the like, but are deficient in numerous respects. See, for example, U.S. Patent Nos. 5,233, 5,293, 5,311, 5,431, 5,521, 5,614, 5,721, 5,733, 5,896, 6,921, 7,366, 7,471, and 7,513, 6,761, 7,821. 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, complex design, and cumbersome use.

To address the limitations of the strength training and exercise equipment referenced above, the present inventor has developed a novel system of exercise equipment and associated methods of use. The equipment developed by the present inventor and detailed below includes a wearable device and associated accessories that are simple, lightweight, and easy to use, allowing a user to perform a variety of strength training exercises without the need for equipment typically found in fitness or physical therapy centers. The device described herein includes a wearable vest with strategically positioned connection points, such as loops or rings, to which a stretch cord of variable length is attached. The ends of the stretch cord have a connector, such as a carabiner clip, that allows one end of the cord to hook to a connection point on the vest and the other end of the cord to attach to a loop on a handle, bar, arm strap, leg strap, foot strap, etc., to engage the user's limb. The connection points on the vest are strategically located so that a user can perform a variety of strength training exercises while pulling or pushing on the ends of the stretch cord. Additionally, the vest is adjustable to obtain a close, non-slip fit for the user. Additional features include pockets on the vest to hold weight bags or inserts, or to store stretch cords, water bottles, etc. A removable backpack and other accessories and features are shown in the drawings and discussed in the detailed description below.

In another preferred form of the invention, the tension or length in the cord can be adjusted, such as by changing the strength resistance or length of the cord. In a preferred embodiment, the strength resistance or length of the cord can be adjusted by changing the cord to a different cord.

According to yet another broad aspect of the invention, there is provided a method of using an exercise system. The method includes the steps of obtaining an exercise system including an openable and reclosable vest having a closure means for securing the vest in a closed condition and a plurality of loops located on a 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 removably attaching 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 to enable a variety of exercises by pulling or pushing the at least one stretch cord in a variety of directions at various locations on the vest. The method includes the steps of donning 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 stretch the stretch cord.

In an alternative mode of use and benefit enabled by the present invention, the user combines arm and leg exercises while stationary or moving.

In alternative aspects and benefits of the method of use enabled by the present invention, the user can incrementally change the resistance in the stretch cords over the course of a workout by changing the stretch cords to different weights (different weights meaning different levels of resistance to stretching, usually measured in pounds or kilograms) or by increasing or decreasing the number of stretch cords attached to the handles or straps to increase or decrease the amount of force required to stretch the cords. In alternative aspects and benefits of the method of use enabled by the present invention, by changing the connection points on the vest, handles, and straps, the user can change the direction of movement of the hands, arms, legs, and/or feet to engage different muscles required to move the handles and/or straps over the course of a workout. Thus, in alternative aspects and benefits of the method of use enabled by the present invention, the user can incrementally change both the stretch cords and the connection points on the vest, handles, or straps over the course of a workout to change the amount and/or direction of resistance felt in the handles or straps (and thus change the muscles and/or amount of muscle effort the user engages to move the handles or straps). Cords of various lengths and weights can be easily carried in pockets in the vest during the workout, providing convenient access to the cords so that the user can change or add cords to connect to the vest, handles, and/or straps during the workout. Thus, the combination of features of the present invention allows for progressive strength training workouts while stationary or on the move (such as while walking, jogging, or running on a track or on a course where the user leaves the starting point). It is believed that the system allows for new types of progressive strength loading exercises on the move, thereby enabling new types of workouts that combine strength training and aerobic exercise for users of all fitness levels.

In an alternative aspect of the invention, a weight bag or other form of weight insert can be inserted into a pocket on the front and/or back of the vest. Thus, while the vest, handles, and straps are in use, the weight bag or insert can be used by the user to modify and/or enhance the workout.

In an alternative separate aspect of the invention, the vest includes a brace member located at a rear portion of the vest, the vest functioning as a back brace. The brace member is preferably removably secured to the vest. More preferably, the brace member is removably secured within a pocket located at the rear portion of the vest. In one preferred form, the pocket that holds the brace member has an arcuate tapered configuration that tapers from a wider open end, closable by a zipper, at the bottom of the vest to a narrower closed end at the top of the vest. The brace member preferably has an arcuate tapered configuration that tapers from a wider bottom end to a narrower closed top end.

In this alternative form of the back brace embodiment of the present invention, the vest is provided with a fastening strap located proximate the geometric center of the brace member. The fastening strap on the vest located proximate the center of the brace member preferably extends into the back portion of the vest such that the brace member is located between the user's spine and the fastening strap.

In accordance with one preferred form of the back brace embodiment of the present invention, the brace member is a composite of a rigid substrate portion that faces away from the user of the vest and a compliant portion that faces the user of the vest. The rigid substrate portion is preferably a rigid polymer and the compliant portion is preferably a closed cell foam material.

52-57, the inventors have discovered that by connecting multiple stretch cords extending from the same attachment (e.g., handle 44, foot straps 70, wrist sleeves 350, knee sleeves 360, etc.) to different attachment points or loops 8a-8j on the vest 1, novel exercises can be presented to multiple muscle groups throughout the user's range of motion. The cords can have different lengths and strengths of resistance to vary the degree of resistance and range of motion offered by the stretch cords in use. FIG. 52 shows a form of vest 1 with hand grips 44 attached to loops 8d and 8h by two different cords, which have increased resistance compared to using a single cord connected to a single loop, and further provide additional resistance for a greater range of motion in both directions, upwards and downwards, as the user moves their arms up and down. Fig. 53 shows a configuration of vest 1 with hand grips 44 attached to loops 8e and 8f by two different cords for arm curls with increased resistance, and further shows foot straps 70 attached to loops 8b and 8c by two different cords for leg extension or squat exercises with increased resistance, whereas Fig. 54 shows a pair of foot straps 70 attached to cords connected to lower loops on vest 1 at different points 72 and 73 for different leg extension or squat exercises with increased resistance. Fig. 55 shows the use of two back loops 8i and 8j that connect pairs of cords to a pair of knee sleeves 360 and a pair of foot straps 70 to provide resistance as the user exercises their lower legs. Fig. 56 shows a user wearing a forearm sleeve 350 connected to two side loops 8d and 8e for hands-free resistance along with all arm exercises. FIG. 57 shows a combination exercise using a forearm sleeve 350 and hand grip 44, in which three separate loops 8g, 8a, 8b on the vest 1 are utilized. Those skilled in the art will recognize that numerous other multi-point exercises are possible using the vest 1 and one or more attachments.

The exercise system and method of using the vest 1 and accessories disclosed herein includes a user donning and wearing the vest 1. Depending on the exercise(s) to be performed, the user selects the length of the stretch cord(s), the strength of resistance of the stretch cord, and whether or not to double the stretch cord for added resistance. For example, for exercises using connections to the shoulder loops 8g and 8h or lower loops 8c and 8f on the vest, the user may select a stretch cord 50 having an unstrained or resting length ranging from about 4 inches (102 mm) to about 14 inches (355 mm) to perform a straight arm exercise. In one preferred embodiment, a cord of about 8 inches (203 mm) in length is used. For example, a shorter cord may be preferred, see Figs. 17a, 17g, 17i, 17j, 17o, and 17p. Also, a medium length cord may be used, see Figs. 17e, 17k, 17l, and 17m. Shorter cords, such as 6 inch (152 mm), 7 inch (178 mm), 8 inch (203 mm), or 9 inch (229 mm) cords, are preferred for exercises that require less stretching, such as shoulder presses, chest presses, etc. When performing bicep curls, the user can select shorter cords, i.e., stretch cords having lengths of approximately 6 inches (152 mm), 7 inches (178 mm), or 8 inches (203 mm), and attach them to the front lower loops on the vest. For exercises that use the foot bar 75 or foot straps 70, the user can select longer stretch cords having lengths ranging from approximately 16 inches (406 mm) to 28 inches (711 mm). In one preferred embodiment, an 18 inch (457 mm) length is used. See, for example, the exercises shown in Figures 17b, 17c, 17f, 17h, and 17n. For exercises that use thigh straps, such as the Kneeling Fire Hydrant exercise or the Clamshell exercise, the user may choose a shorter stretch cord, ranging from 8 inches (203 mm) to 14 inches (355 mm). The optimal length of the stretch cord may depend on the user's build and limb length.

After selecting the stretch cords, the user can then select any combination of handles (see selections in Figs. 6, 7, 7a, and 8), foot straps (see selections in Figs. 9a and 9b), bars (see selections in Figs. 10-13), thigh straps (see Fig. 14), forearm straps (see Figs. 44-47), and knee straps (see Figs. 48-51) depending on the exercise to be performed. The user can then perform the exercise. Various combinations of vests, stretch cords, foot straps, thigh straps, knee straps, handles, and bars allow the user to select from a variety of exercises shown in Figs. 17a-17p above, and many others not shown.

The exercise devices and systems disclosed above, and associated methods of use, allow users to perform a variety of exercises without the need for bulky equipment typically found in fitness centers, physical rehabilitation centers, homes, and the like. The disclosed systems advantageously use the human body as an anchor for stretch cord exercises, eliminating the need to attach the ends of the stretch cord to an external anchor. Many of such exercise devices and associated systems, and associated methods and exercises, do not utilize gravity and can be used and performed in a weightless environment. Using the disclosed vests, devices, and stretch cord systems, a user can wear the vest, use the device, and perform exercises while sitting, standing, lying down, walking or running, indoors or outdoors, and while stationary or moving. The disclosed systems are useful for individuals with strength or mobility impairments, including wheelchair users, to perform numerous strength training exercises. The thigh strap, forearm strap, and knee strap embodiments are useful for individuals with hand, foot, or lower leg amputees to perform a variety of strength training exercises. Unlike carrying and using weights such as dumbbells while walking or running, the disclosed system allows the ability to combine resistance training, such as performing arm exercises using a vest and stretch cords while simultaneously walking or running, without putting a lot of weight on the lower extremities. The various sets of stretch cords are so lightweight that they can be carried in a storage pocket during a stationary or mobile workout (e.g., while walking or running). At any point during the workout, the selection and configuration of the stretch cords can be changed to increase or decrease the resistance applied to the handle while stationary or mobile. Thus, the present invention allows for the use of dynamic and progressive resistance training along a path, while mobile, or combined with aerobic training.

For example, in a method of use enabled by the present invention, a user can incrementally change the resistance in the stretch cords over the course of a workout by changing the stretch cords to different weights (different weights meaning different levels of resistance to stretching, usually measured in pounds or kilograms) or by increasing or decreasing the number of stretch cords attached to the handles or straps to increase or decrease the amount of force required to stretch the cords. In an alternative aspect and benefit of a method of use enabled by the present invention, by changing the connection points on the vest, handles, and straps, a user can change the direction of movement of the hands, arms, legs, and/or feet over the course of a workout to engage different muscles required to move the handles and/or straps. Thus, in an alternative aspect and benefit of a method of use enabled by the present invention, a user can incrementally change both the stretch cords and the connection points on the vest, handles, or straps over the course of a workout to change the amount and/or direction of resistance felt in the handles or straps (and thus change the muscles and/or amount of muscle effort the user engages to move the handles or straps). Cords of various lengths and weights can be easily carried in pockets in the vest during the workout, providing convenient access to the cords so that the user can change or add cords to connect to the vest, handles, and/or straps during the workout. Thus, the combination of features of the present invention allows for progressive strength training workouts while stationary or on the move (such as while walking, jogging, or running on a track or on a course where the user leaves the starting point). It is believed that the system allows for new types of progressive strength loading exercises on the move, thereby enabling new types of workouts that combine strength training and aerobic exercise for users of all fitness levels.

In an alternative embodiment of the present invention, weight bags or inserts can be added to the pockets on the front and/or back of the vest. Thus, while the vest, handles, and straps are in use, the weight bags or inserts can be used by the user to modify and/or enhance the workout.

The disclosed vests, stretch cords, handles, and various bars are lightweight and take up little space, making them portable and easily transported in automobiles, airplanes, etc., and usable at any chosen location (such as another residence or a hotel room). The disclosed equipment and systems can be installed at any location with minimal installation effort and the disclosed methods of use can be performed. The disclosed equipment, systems, and related methods of use avoid the drawbacks associated with other types of fitness equipment, including high cost, the need for multiple pieces of heavy and cumbersome equipment, the need for large amounts of space, lack of portability, and lack of practicality with respect to the variety of exercises that can be performed with a single or very few pieces of equipment. The disclosed equipment, systems, and methods of use are not known in the prior art and are believed to be a breakthrough in the current state of the art in training and exercise equipment, and related systems and methods of use.

Although the preferred embodiment of the invention includes attachment means between the components (stretch cord, vest loop, handle) in the form of a carabiner-style retractable hook, it will be appreciated that other attachment means can be utilized. For example, the stretch cord can be tied or threaded to the vest or hand grip, Velcro or snap fit connections can be used, and other functionally equivalent mechanisms can be used.
