Description
FIELD

The present invention relates to a wearable resistance loop (an apparatus) that facilitates the building of the gluteus maximus muscles.


BACKGROUND

During the 1970's the world began a fitness revolution. In the 1970's many Americans for the first time began exercising at home, running, or lifting weights on a daily basis. The importance and benefits of exercise have become more and more apparent since then with Americans living healthier and longer lives. Resistance training has been increasingly identified as an important way to improve not only specific targeted regions, but also cardiovascular, and mental health. Today, in 2021, especially with the advent of social media, exercising and lifting weights has continued to grow and in popularity and size. However, still today, many people struggle to consistently access and maintain fitness regimens. This often stems from the large and heavy resistance-training machines that either take up space in a home or require going to a gym. Given the large and heavy nature of resistance training devices, it is also difficult to exercise outdoors, when ‘on-the-go’, or when traveling. Therefore, there is a need for portable, efficient, and convenient, resistance exercise equipment that can be easily transported, and used anywhere, and does not require excessive set-up in a user's home, or other exercise location.


A glute bridge exercise is performed by laying on your back with knees bent and driving the hips into the air while flexing the gluteus maximus muscles. The glute bridge exercise is also known as a hip thrust exercise or a laying hip thrust exercise, each shall be known collectively in this specification as a glute bridge exercise. A glute bridge exercise with resistance is performed by laying a weighted bar across your hips while driving your hips upward. Or alternatively, there are weight machines that add resistance to your hips and waist area and or surrounding areas as you drive your hips forward. The weighted bar and or the weight machines are expensive, bulky, and typically require at a minimum a home gym if not a full corporate gym.


The present invention allows the glute bridge exercises to be performed with resistance in any location in which a glute bridge without resistance may be performed, and without the need for expensive and bulky gym equipment.


SUMMARY

In one embodiment of the invention, the invention comprises a loop, band, strap, or belt (collectively defined herein as a loop) of a stretchable material with additional openings within the loop to place and secure one's feet into the loop. The loop may be a closed loop in some embodiments, and in other embodiments, may be an open loop such that a strap has foot openings attached or formed at opposite ends of the strap.


To use the present invention one inserts their feet into the foot openings of the loop and then moves the alternative portion of the loop over their knees and around the front of their hips which then provides resistance to the hips while performing a glute bridge and while keeping the loop secured to the feet.


In a further embodiment of the invention, securing the loop under one's feet by placing one's feet into the foot openings prevents the loop from retracting and subsequently striking the individual's posterior (hamstrings or glutes) while performing a glute bridge exercise. In one embodiment of the present invention a loop or unit is worn on the feet via the foot openings and across the waist simultaneously. In a further embodiment of the present invention a loop is worn on the feet, alongside each leg, and across the waist of a user simultaneously. In a further embodiment of the present invention the loop is a single and cohesive unit worn on the feet and on the front of the waist or the front of the user's upper legs (i.e. the quadriceps and tensor fasciae latae) simultaneously for the purpose of resistance training.


In one embodiment of the present invention the invention is composed of a material which is stretchable or flexible.


In one embodiment, the present invention consists of a loop with only two openings within the loop to place and secure one's feet and is a singular unit, and is not comprised of any additional accessories, attachments, or accoutrements. In a further embodiment of the present invention, the loop or open loop may be put on or worn without fastening, tying, or any type of adjustment. In a further embodiment of the present invention, the loop rest on the upper hips of the user and provides resistance without encircling the waist.


In a separate embodiment of the present invention the feet openings are each comprised of a strip of material attached to the larger loop creating openings in which a person's feet may be inserted.


In a further embodiment the loop may be comprised of material that is double-layered with the two layers left unconnected at each foot opening for the individual's feet to fit into the loop. In a further embodiment, the two layers may be connected together continuously or periodically along the remainder of the length of the loop.


In a further embodiment of the present invention an additional piece of material or additional tube or open sock is attached within the unsewn openings of the double-layered loop, band, or belt. In a further embodiment the flexible material in which the loop is made from will allow individuals with different foot size to use the loop.


The securing of the loop under one's feet by use of the foot openings is a key advantage of the present invention over resistance bands without foot openings. An additional aspect of the present invention is that securing of one's feet into the loop allows the individual to adjust the resistance by moving their feet forward and back while in position to perform the glute bridge. The capability to adjust the resistance of the loop vis-à-vis the positioning of the feet in the loop is a key advantage of the present invention over equipment currently available on the market today. The further away the feet are from the user's hips, the tighter the band will be and therefore the greater the resistance will be.


In a further embodiment the loop may be adjusted for individuals of different heights at extension regions of the apparatus such as by use of a buckle, a clamp, a hook and loop connector such as Velcro®, or any other adjustment mechanism.


In a further embodiment the loop may be composed of a material with different resistances to make the glute bridge exercise more or less difficult. In an additional embodiment the loop is made from a material which will not chafe or damage an individual's skin. The difference of materials in a key advantage of the present invention over rubber resistance bands.


In a further embodiment of the present invention an additional piece of material or additional tube or open sock is attached within the unsewn openings of the double-layered loop, band, or belt. In a further embodiment the flexible material in which the loop is made from will allow individuals with different foot sizes to use the loop.


In an additional embodiment the loop is made from a material which will not chafe or damage an individual's skin such as a stretchable fabric including, but not limited to spandex. The difference of materials in a key advantage of the present invention over rubber resistance bands. In a further embodiment, the loop may have a predetermined resistance level based on the flexibility of the material of which it is composed. In another embodiment of the invention, the length of the loop is made longer or shorter to increase or decrease the resistance of the loop and consequently make the glute bridge exercise while wearing the loop more or less difficult. In a further embodiment the loop may be adjusted in length to add resistance and therefore make the glute bridge exercise while wearing the loop more or less difficult. In a further embodiment the loop is composed of stretchable and nonstretchable material. In a further embodiment the length the of the loop is composed of stretchable and non-stretchable material that may be adjusted in length without increasing the resistance of the loop.


In a further embodiment of the invention, the loop has an additional pad surrounding the loop where the loop contacts an individual's hips. In a separate embodiment the additional pad is a long cylindrical tube pad formed to either be permanent or removable from the loop. In a further embodiment, said additional pad is in the shape of a long triangle to prevent the loop from rolling down the individual's waist while performing the glute bridge and can be permanent or removable.


In a further embodiment the removable pad will be of any shape or size to aid in comfort and reduce slipping of the loop while performing glute bridges. In another embodiment of the invention, a portion of the loop is composed of a padded or more padded material where the loop will make contact with an individual's hips to reduce any discomfort caused by the resistance in the loop while performing a glute bridge. In another embodiment of the invention, the portion of the loop which contacts an individual's hips and the front of the user's waist is made from a material with a higher friction coefficient to reduce slippage of the loop while performing glute bridges. In a further embodiment of the invention, any of the said pads, whether removable or not removable, are made from a material with a higher friction coefficient to reduce slippage while performing a glute bridge exercise.

DETAILED DESCRIPTION

The following description and examples illustrate a preferred embodiment of the present invention in detail. Those of skill in the art will recognize that there are numerous variations and modifications of this invention that are encompassed by its scope. Accordingly, the description of a preferred embodiment should not be deemed to limit the scope of the present invention.


In one embodiment of the present invention the present invention consists of a loop of flexible material with two foot openings and capable of being worn on the user's feet and across the user's waist while performing a glute bridge exercise.


In alternative embodiments of the present invention the two openings for the feet are created by attaching an additional strip of material to the loop of flexible material. In a preferred embodiment the additional strip of material is also flexible material so that openings are flexible on both sides and synch around a user's feet. In a further embodiment the additional material is different material than that of the loop to enhance the wearability (fit) of a user's feet. For example, in some embodiments the additional material attached to the loop to create the foot openings may be more flexible than the loop material to increase the range of size of feet and shoes or both which may fit into the openings. In a further embodiment the additional material is soft or lined to enhance the wearability (fit) and comfort (feel) of the user's feet. The strip or strips forming the foot openings may be permanently attached to the loop in one embodiment. In another embodiment, one end of the strip or strips may be permanently attached to the loop to form the foot opening, with an opposite end of the strip being removably connectable to the loop, so as to allow adjustable foot opening sizing, as well as easy release of the feet from the foot openings. In still another embodiment, both ends of the strip or strips may be removably connectable to the loop, so as to allow adjustable foot opening sizing, as well as easy release of the feet from the foot openings.


In a preferred embodiment the present invention the loop and the additional material to create the foot openings are 4 inches wide. In further embodiment the loop material and additional attached material for the foot openings are 1 inch to 15 inches wide. In a further embodiment of the present invention the additional material attached to the loop to create the foot openings varies in width from the loop from which it is attached.


In preferred embodiment of the invention the additional material attached to the loop to create the foot openings is 8 inches in length and is secured at each end to an area which is 6 inches in length along the loop. In further embodiments of the present invention the additional material attached to the loop to create the foot openings may range from 2 inches to 12 inches and may be attached to a portion of the loop that ranges from 2 inches to 12 inches. In the preferred embodiment the additional length of the attached material in comparison to the loop material creates an arch shape or bows the additional attached material so that a user may insert their feet. In another embodiment of the present invention the additional material attached to the loop to create the foot openings are attached to a portion of the loop that is the same length as to not create arches or bows for the foot openings, but rather an unopened foot opening or envelope. In a preferred embodiment of the invention the additional material attached to the loop to create the foot openings are spaced 5 inches apart. In further embodiment of the present invention the foot openings are spaced anywhere from ½ of an inch apart to 60 inches apart. In a further embodiment the additional material attached to the loop to create the foot openings is sewn or attached in diagonal fashion to create an opening that is slightly larger on one side than the other, in order to create a tapered or contoured foot opening.


In a further embodiment the additional openings are paired for different sizes of feet, for example women's feet and men's feet, or, with shoes and without shoes. It should be noted however, that the invention contemplates use of flexible material which is capable of stretching and securing a majority of feet and shoes of various different sizes with one set of openings. The foot openings may be used by a user having shoes on, wearing socks, and/or barefoot, without straying from the scope of the invention.


In an additional embodiment of the present invention the loop has a single opening for both feet to fit securely into. Such single opening may be created using additional material in various lengths as described above for paired openings and multiple pair openings.


In additional embodiments of the present invention the loop may be made from two strips or pieces of material attached together to create a double loop. In a preferred embodiment, the material used for the outer loop and the inner loop will be of the same width. In a preferred embodiment the inner loop will not be attached to the outer loop in certain areas to create openings for the user's feet. In a preferred embodiment the inner loop will be four inches longer than the outer loop such as to create two foot openings or sleeves with arched or bowed foot openings. In a preferred embodiment the openings will be composed of sections of material which are 6 inches on the outside band and 8 inches on the inside band to create sleeves and the openings will be 5 inches apart. In a further embodiment the foot openings may vary in size as demonstrated above for the foot openings created by the additional attached material. In further embodiments such double loop may be attached or sewn together in various places so as to leave openings which may be worn on the feet. In additional embodiments the double loop will be composed of two pieces of material identical or nearly identical in length to create no arches or bowed effect at the foot openings. In such an embodiment the foot openings or sleeves are intentionally not perceivable.


In a preferred embodiment of the present invention the loop will be composed of material with known resistance. In a further embodiment, the loop may have a predetermined resistance level based on the flexibility of the material in which they are composed of. In one embodiment of the present invention the resistance of the material will be equivalent to 50 pounds or resistance. In additional embodiments of the invention the resistance of the material will range from 1 pound of resistance to 1000 pounds of resistance. In a further embodiment of the present invention the double loops discussed above may be created with material with the same resistance to create a final double loop for use with double the resistance (for example two 50 pound resistance bands attached together will create a 100 pound resistance double loop). In further embodiments the double loop may be created with material with different resistances to create a final double loop with varying final resistances, for example a 50 pound resistance loop attached to a 100 pound resistance loop for a total of 150 pound final resistance loop.


In a preferred embodiment of the present invention the loop will be 26 inches long when laid flat, and therefore will be composed of 52 inches of material when not enclosed in a loop. In an additional embodiment of the invention the loop will be 5 inches to 100 inches when laid flat, and therefore be comprised of 10 inches to 200 inches of material. In another embodiment of the invention, the length of the loop is made longer or shorter to increase or decrease the resistance of the loop, and consequently make the glute bridge exercise while wearing the loop more or less difficult. In a further embodiment the loop may be adjusted in length to add resistance and therefore make the glute bridge exercise while wearing the loop more or less difficult. In a further embodiment the loop is composed of stretchable and non-stretchable material. For example the portion of the loop that is worn along the side of the legs is stretchable and is a designated resistance while the portion the loop is worn on the waist and over the feet is non-stretchable, or vice-versa. In a further embodiment of the invention the non-stretchable or, portion of the loop that does have flexible resistance will be adjustable to allow the loop to be set resistance but be adjustable for different sized users. For example, a 50-pound resistance band could be extended to 30 inches or decreased to 20 inches while maintaining the same resistance.


In a preferred embodiment of the present invention the loop is adjustable through use of a locking buckle which would be placed on the portion of the loop that is worn on the outer legs of the user. In a further embodiment the locking buckle would be positioned on both sides of the loop that is worn on the outside of the legs. In an additional embodiment the adjustable locking buckle or buckles may be placed anywhere along the length of the loop


In a further embodiment of the present invention the loop may be constructed of rubber tubing, or bungee like material. In a further embodiment the loop could be comprised of a series of rubber tubing, or bungee like material so that the foot openings would be formed by attachments of the tubing or bungee like material at specified locations. The foot openings between the tubing could be any dimension suitable for use.


In a further embodiment of the present invention, the loop has an additional pad surrounding the loop where the loop is worn across the waist. In a further embodiment the pad is a long cylindrical tube which may be removed from the portion of the loop worn across the waist. In a further embodiment, said additional pad is in the shape of long triangle to ensure the tube stays along the waist of the user. In a further embodiment the pad may be attached to the loop where the loop is worn along the front of the waist. In a separate embodiment of the present invention the pad is placed on any portion of the loop which is suitable. In another embodiment of the present invention the pad is permanently attached to the loop. In a preferred embodiment of the present invention the loop comprised of rubber tubing or bungee cord like material has a pad surrounding the tubing to distribute the weight across the waist more broadly.
