A club for ballistic and dynamic exercises

Abstract

An improved exercise club may include a body made of frustoconical shaped lower and intermediate portions, and a handle attached to a smaller end of the intermediate portion. The club is ergonomically designed taking into account specific human anatomy and shape (e.g., the back, trapezius, shoulders, etc.) to allow a user to leverage these parts of body as a tool to be used in conjunction with the club's proportions and may facilitate a range of exercises with comfort and safety for the user. The shape of the club may be defined by different ratios, which ensures that the club can be safely rolled over the shoulder and behind the head, and thrown in specific patterns, while also allowing the user to maintain balance of the club on his body.

Description

[0001] A CLUB FOR BALLISTIC AND DYNAMIC EXERCISES

[0002] Field of Invention

[0003] [1] The present invention relates to the field of equipment for physical exercises. In particular, the present invention pertains to a club configured for ballistic and dynamic exercises by moving in specific patterns to improve the user's strength, agility, and balance.

[0004] Background

[0005] [2] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0006] [3] Exercise clubs are well-known for being a fundamental tool in the field of physical training. Their origin can be traced to diverse cultures around the world, where the clubs have been employed both to enhance athletic ability and to develop strength and endurance.

[0007] [4] The history of clubs dates back to ancient civilizations, such as the Persians and Indians, who used primitive forms of this equipment in their war training and physical preparation. Over the centuries, clubs have evolved in design and function.

[0008] [5] Using existing Indian clubs for fitness provides numerous biomechanical advantages and benefits. The existing Indian clubs improve shoulder mobility and stability by promoting a full range of motion and reinforcing stabilizing muscles, while enhancing coordination and motor control through complex, multi-directional movements. The unique grip strengthens hand and forearm muscles, and the swinging motions increase wrist flexibility. Further, core strength and stability are enhanced by using the existing Indian clubs, as the rotational movements engage the core, contributing to better posture and reduced back pain. Indian club exercises mimic functional movements, promoting joint health through smooth, controlled actions that lubricate and maintain flexibility. Finally, their versatility and accessibility make Indian clubs a valuable tool for diverse fitness routines.

[0009] [6] However, conventional clubs ignore ergonomics, and therefore compromise comfort and safety of the user. In addition, they do not take into account specific human anatomy and shape (e.g., the back, trapezius, shoulders, etc.) to allow leverage of these parts of the body as a tool to be used in conjunction with the club's proportions.

[0010] [7] Existing Indian club devices on the market highlights several potential drawbacks in their design. Many clubs come with limited weight options, for instance, those that are lighter in weight, are insufficient for advanced users seeking greater resistance. Further, certain existing club devices that are heavier become dangerous to use since they are usually made from metal or steel if they are that heavy, making it difficult for users to find the right clubs that suit their needs.

[0011] [8] Additionally, the existing Indian club devices lack ergonomic design features as it relates to grips being uncomfortable and unsuitable, leading to difficulties in maintaining a secure hold. Also, inconsistent weight distribution or poor balance in some Indian club designs can affect the fluidity and safety of movements, which can hinder the effectiveness of workouts and increase the risk of injury.

[0012] [9] Some existing clubs on the market come with longer, sometimes extendable, handles which can cause tilting and instability in rotational movements. Whereas a club with a shorter handle may provide more proportional leverage to the user, improving stability and preventing excessive tilting. Further, material quality of the existing clubs can also be a concern, with cheaper plastics or low-grade wood leading to durability problems over the long haul. These concerns about poor-quality materials can lead to durability issues, including cracks or breaks. Additionally, the finish on some clubs can be rough or poorly applied, affecting user comfort and safety. Nevertheless, storage and portability can also be one of the challenges to the users, due to their size, shape, and weight which can be cumbersome, especially in heavier clubs.

[0013]

[0010] The above stated drawbacks with conventional and existing exercise clubs often neglect ergonomics and fail to consider specific human anatomy, such as the contours of the back, trapezius, neck, and shoulders, which are important for leveraging the club's proportions to enable users to perform a variety of exercises more safely and effectively, including in performing unique ballistic and dynamically explosive exercise movements that would not be possible with existing clubs.

[0014] Summary

[0015]

[0011] There is, therefore, a need to overcome the above stated drawbacks of conventional clubs by providing an improved club for ballistic and dynamic exercises by moving in specific patterns, to improve the user's strength, agility, and balance.

[0016]

[0012] It is an objective of the present invention to provide an improved club that ensures a greater functionality, comfort, improved ergonomics, and enhanced safety to the user during exercises.

[0017]

[0013] It is an objective of the present invention to provide a club that provides more leverage to the user, improves stability, and prevents tilting.

[0018]

[0014] It is an objective of the present invention to provide a club that ensures an improved range of motion during exercises.

[0015] It is an objective of the present invention to provide a club that facilitates throwing and turning the club from one shoulder to the other in an explosive exercise associated with shoulder rolling.

[0019]

[0016] It is an objective of the present invention to provide an ergonomically designed club that fits in the correct position and in a hollow of the shoulder so that it rested comfortably and balanced on a muscle tissue of the trapezius.

[0020]

[0017] It is an objective of the present invention to provide an improved club with a shape such that the user is able to launch or catapult the club forward from the body to perform exercises of a dynamic and explosive nature.

[0021]

[0018] Aspects of the present invention relate to an exercise club. The exercise club (also referred to simply as club, herein) may comprise an elongated handle that defines a longitudinal axis of the club, and a body coupled to a distal end of the handle. The body includes a distal portion (also referred to as lower portion, herein) and an intermediate portion located between the handle and the distal / lower portion.

[0022]

[0019] One or both of the distal portion and the intermediate portion may have a frustoconical shape and the two may be positioned coaxially with the longitudinal axis of the club with the handle being fixed to a smaller end of the intermediate portion, and a larger end of the intermediate portion being fixed to the smaller end of the lower portion. The larger end of the intermediate portion may, in some cases, be of the same or at least substantially the same size as the smaller end of the lower portion to provide a smooth transition from the intermediate portion to the lower portion.

[0023]

[0020] In an aspect, the frustoconical shaped lower portion and intermediate portion have optimized proportions to provide greater comfort, ergonomics, and safety to the user during exercise, such as by better conforming to the unique contours of the shoulder, neck, and trapezius regions of the body.

[0024]

[0021] In one or more embodiments, a ratio of a length of the handle to a sum of lengths of oblique sides of the frustoconical shaped lower portion and the intermediate portion may be in a range of 1:2.10 to 1:2.50 or about 1:2.10 to about 1:2.50. In a preferred embodiment, said ratio can be about 1:2.31.

[0025]

[0022] In one or more embodiments, a ratio of a diameter of a smaller end to a diameter of the larger end of the frustoconical shaped lower portion may be in a range of 1 : 1 to 1.10: 1 or about 1 : 1 to about 1.10: 1; and a ratio of the diameter of the smaller end to the length of the oblique side of the frustoconical shaped lower portion may be in a range of 0.7: 1 to 1.1: 1 or about 0.7: 1 to about 1.1 : 1. In a preferred embodiment, the ratio of the diameter of the smaller end to a diameter of the larger end of the frustoconical shaped lower portion may be about 1.08: 1; and the ratio of the diameter of the smaller end to the length of the oblique side of the frustoconical shaped lower portion may be about 0.92: 1.

[0026]

[0023] In one or more embodiments, a ratio of a diameter of a larger end to a diameter of a smaller end of the frustoconical shaped intermediate portion may be in a range of 4.50: 1 to 4.90: 1 or about 4.50: 1 to 4.90: 1; and a ratio of the diameter of the smaller end to the length of the oblique side of the frustoconical shaped intermediate portion may be in a range of 0.4: 1 to 0.7: 1 or about 0.4: 1 to 0.7: 1. In a preferred embodiment, the ratio of the diameter of the larger end to the diameter of the smaller end of the frustoconical shaped intermediate portion may be about 4.68: 1 and / or the ratio of the diameter of the smaller end to the length of the oblique side of the frustoconical shaped intermediate portion may be about 0.55: 1.

[0027]

[0024] In one or more embodiments, one or more of the lower portion, the intermediate portion, and the handle may be hollow, and can be fdled with water to increase weight of the club.

[0028]

[0025] In one or more embodiments, the handle may include a padded sleeve or cover. In one or more embodiments, the club may include a sleeve around the lower portion and the intermediate portion. In some cases, the sleeve may be made of a soft and malleable material, such as but not limited to Silicone or Neoprene rubber, and may comprise fillers. The sleeve may be fixed removably around the lower portion and the intermediate portion, or may be fixed thereto by glue or any other suitable means.

[0029]

[0026] In one or more embodiments, the club may include a cap fixed at a proximal end (also referred to as upper end) of the handle. The cap can have internal threads for being fixed to an upper end of the handle. Further, the cap can have a shape with an increasing diameter towards the upper end in some embodiments. The shape helps to prevent the handle from slipping off as a user holds the club at the handle for performing exercises.

[0059] Detailed Description

[0060]

[0058] The following is a detailed description of embodiments of the invention depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the invention. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.

[0059] All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the invention and does not pose a limitation on the scope of the invention otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the invention.

[0061]

[0060] As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result to function as indicated. For example, an object that is “substantially” cylindrical or “substantially” perpendicular would mean that the object / feature is either cylindrical / perpendicular or nearly cylindrical / perpendicular so as to result in the same or nearly the same function. The exact allowable degree of deviation provided by this term may depend on the specific context. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result. For example, a structure which is “substantially free of’ a bottom would either completely lack a bottom or so nearly completely lack a bottom that the effect would be effectively the same as if it completely lacked a bottom.

[0062]

[0061] Similarly, as used herein, the term “about” is used to provide flexibility to a numerical range endpoint by providing that a given value may be “a little above” or “a little below” the endpoint while still accomplishing the function associated with the range.

[0063]

[0062] Various terms are used herein. To the extent a term used herein is not defined, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.

[0064]

[0063] Exercise clubs offer a number of benefits to their users. Among the main benefits of some embodiments are: (i) Development of Strength and Endurance: Regular use of clubs allows strengthening of the muscles of the core, upper and lower limbs, promoting development of muscle strength and endurance; (ii) Improvement of Coordination and Balance: The fluid and controlled movements required during club exercises help to improve motor coordination and body balance; (iii) Functional Training: Clubs allow for the performance of a variety of exercises that simulate the body's natural movement patterns, making them an effective tool for functional training and improving overall physical ability; (iv) Versatility: The exercise clubs can be used by practitioners of different fitness levels, from beginners to elite athletes, and offer a wide range of exercises adaptable to different training goals.

[0065]

[0064] However, the conventional clubs for exercise do not take into account ergonomics, and therefore compromise comfort and safety for the user. In addition, they do not take into account specific human anatomy and shape (e.g., the back, trapezius, shoulders, etc.) to allow leverage of these parts of the body as a tool to be used in conjunction with the club’s proportions.

[0066]

[0065] In an aspect, the proposed club of the present invention has a shape of optimized proportions that are based on an intense research to provide greater functionality, comfort, ergonomics, and safety to the user during exercise, thus allowing a user to perform a plurality of different and unique exercises with more comfort and safety. These studies resulted in a modification of overall ergonomics, including for some embodiments handle length, diameters, and / or inclinations / angles of the frustoconical shaped body, to ensure safe and effective use during unique fitness workouts.

[0067]

[0066] Different evaluation criteria used during the rigorous testing and experimentation are listed below:

[0068] Functionally Useful:

[0069]

[0067] The proportions of diameters of the smaller and larger ends of the two frustoconical shaped portions of the body of the club, as well as ratio of length of the oblique sides of the two frustoconical shaped portions of the body to the respective diameters, were, in some embodiments, selected so that the user could perform specific exercises, such as shoulder rolling, as well as more explosive movements. It was important for some embodiments that the device be built to accommodate and work with the anatomical shape and structure of the human shoulder. Otherwise, without the correct distribution of weights and dimensions, it would not be possible to perform these types of exercises or movements.

[0070] User Safety:

[0071]

[0068] Body parts of the user that the club uses and depends on for the variety of movements are the shoulder, upper trapezius, and lateral, and posterior portions of the neck. In this region, there are several areas of the shoulder that are delicate, such as the acromial process in the shoulders, neck, and head. The acromial process is a triangular bony structure that forms the apex of the shoulder and is the part of the shoulder that sticks out at the tip, so it is very sensitive to hard objects and forces. In addition, the head and ears are also positioned in this area, so extra care and attention had to be placed on the safety of the user. The design, ergonomics, and proportions of the club were, in some embodiments, made to fit the correct position and in the hollow of the shoulder so that it rested comfortably and balanced on the muscle tissue of the trapezius. Incorrect proportions could easily result in the user hitting themselves on the head or the club interacting with the acromial process, causing problems or safety concerns during use. Structurally Reinforced:

[0072]

[0069] It was important that the proportions and ergonomics were formed in such a way as to structurally reinforce and strengthen the device as a whole. The absence of the correct proportions between the cone and the cylinder would not only prevent the user from completing the movement safely, but would also weaken and compromise the integrity of the structure as a whole. For example, if the cone is too long, there would be stress on the part of the cone when the club is positioned at the shoulder, which could fail and cause injury during use. If the cone is too long and has a small diameter, with the cylinder being too heavy at the back, these proportions could cause the club to break or fail during use.

[0073]

[0070] Referring now to FIGS. 1 to 3B, where different views of various parts of the disclosed exercise club (also referred to simply as club, herein) are disclosed, the exercise club (A) includes a body and an elongated handle (3). The elongated handle (3) defines a longitudinal axis of the club (A). The body includes a lower portion (1) located on a distal side of the club (accordingly also referred to as distal portion, herein) and an intermediate portion (2), each of the lower portion (1) the club (A) and the intermediate portion (2) of the club () is of a truncated cone / frustoconical shape, as evident from FIGS. 1 and 5. The frustoconical shaped lower portion (1) of the club and the intermediate portion (2) of the club may be arranged such that they are coaxial to the longitudinal axis of the club, with the body coupled to a distal end of the handle (3).

[0074]

[0071] In an embodiment, the frustoconical shaped lower portion (1) and the intermediate portion (2) can be arranged such that their diameter is reduced from the distal / lower end towards the proximal end / upper end.

[0075]

[0072] The handle (3) can be fixed to a smaller end (2B) of the intermediate portion (2), and a larger / bigger end (2A) of the intermediate portion (2) can be fixed to the smaller end (IB) of the lower portion (1). The larger end (2A) of the intermediate portion (2) is of the same size as the smaller end (IB) of the lower portion (1) to provide a smooth transition from the intermediate portion (2) to the lower portion (1).

[0076]

[0073] A ratio of a length (3C) of the handle (3) to a sum of length of oblique side (1C) of the frustoconical shaped lower portion (1) and length of oblique side (2C) of the frustoconical shaped the intermediate portion (2) can be in a range of 1:2.10 to 1:2.50. In a preferred embodiment, said ratio can be 1:2.31.

[0077]

[0074] A ratio of a diameter of a smaller end (IB) to a diameter of the larger end (1A) of the frustoconical shaped lower portion (1) can be in a range of 1: 1 to 1.10: 1; and / or a ratio of the diameter of the smaller end (IB) to the length of the oblique side (3C) of the frustoconical shaped lower portion (1) can be in a range of 0.7: 1 to 1.1: 1. In a preferred embodiment, the ratio of the diameter of the smaller end (IB) to a diameter of the larger end (1A) of the frustoconical shaped lower portion ( 1 ) may be 1.08: 1; and the ratio of the diameter of the smaller end ( 1 B) to the length of the oblique side (1C) of the frustoconical shaped lower portion (1) may be 0.92: 1.

[0078]

[0075] A ratio of a diameter of a larger end (2A) to a diameter of a smaller end (2B) of the frustoconical shaped intermediate portion (2) may be in a range of 4.50: 1 to 4.90: 1; and / or a ratio of the diameter of the smaller end (2B) to the length of the oblique side (2C) of the frustoconical shaped intermediate portion (2) can be in a range of 0.4: 1 to 0.7: 1. In a preferred embodiment, the ratio of the diameter of the larger end (2A) to the diameter of the smaller end (2B) of the frustoconical shaped intermediate portion (2) can be 4.68: 1; and the ratio of the diameter of the smaller end (2B) to the length of the oblique side (2C) of the frustoconical shaped intermediate portion (2) can be 0.55: 1.

[0079]

[0076] In an embodiment, one or more of the lower portion (1), the intermediate portion

[0080] (2), and the handle (3) may be hollow, and can be filled with water to increase weight of the club (A).

[0081]

[0077] In an embodiment, the handle (3) may include a cover. In one or more embodiments, the club (A) may include a sleeve around the lower portion (1) and the intermediate portion (2). The sleeve may be made of a soft and malleable material, such as but not limited to silicone or neoprene rubber, and other composite fillers to improve its performance characteristics. The sleeve may be fixed removably around the lower portion (1) and the intermediate portion (2), or may be fixed thereto by glue or any other means.

[0082]

[0078] As shown in FIGS. 2A and 2B, the two ends of the handle (3) can be threaded (as shown at the two ends of the handle (3) in FIG. 2A), where one of the two ends, i.e., the distal end, can be fixed to the smaller end (2B) of the intermediate portion (2) through the corresponding internal threads provided on the smaller end (2B) of the intermediate portion (2). The other end, i.e., the proximal end (also referred to as upper end) of the handle (3) can include a cap (3 A) fixed thereto through internal threads in the cap (3B), as shown in FIG. 3B. As shown in FIG. 3B, the cap (3A) can have a shape with an increasing diameter towards the upper end / proximal side. The shape can help to prevent the handle (3) from slipping off as a user holds the club (A) at the handle

[0083] (3) for performing exercises.

[0084]

[0079] In an embodiment, the proximal end of the handle (3) can be used to fill water within the inner hollow of the handle (3) and the body, i.e., the lower portion (1) and the intermediate portion (2). The cap (3 A) at the proximal end of the handle (3) can be configured to provide a leak -proof closure of the opening at the proximal end of the handle (3). Any arrangement known in the prior art can be used to provide a leak -proof fitting of the cap (3 A), with the use of threads being a preferred option.

[0080] In some embodiments, the lower portion (1) has a truncated cone shape, where the diameter of the lower end (1A) is larger than the diameter of the upper end (IB). However, m other embodiments, the lower portion (1) can have a shape of a cylinder, where the lower diameter is equal to the upper diameter.

[0085]

[0081] In an embodiment, the proposed clubs (A) can be of various sizes (e.g., small, medium, large), while maintaining the above-defined ratios between the ends and oblique sides of the handle (3), the lower portion (1) and the intermediate portion (2), and therefore, the different sizes shall not compromise the intended usefulness and benefits.

[0086]

[0082] In a preferred embodiment, the exercise club (A) can be made with following measurements:

[0087] • Diameter of bigger end (1A) of lower portion (1): 196.77 mm

[0088] • Diameter of smaller end (IB) of lower portion (1) / Diameter of bigger end (2A) of intermediate portion (2): 182 mm

[0089] • Diameter of smaller end (2A) of intermediate portion (2): 38.9 mm

[0090] • Length of oblique side (1C) of lower portion (1): 212.73 mm

[0091] • Length of oblique side (2C) of intermediate portion (2): 329.4 mm

[0092] • Length of Handle (3): 235.0 mm

[0093] • Length of Cap (3A): 47 mm

[0094]

[0083] In an embodiment, the exercise club (A) of the present invention is hollow and has an opening at the upper / proximal end of the handle (3). The interior of the club (A) can be filled with any substance to increase the weight of the club, such as water, sand, or any other suitable material. Preferably water is used, given its ease of handling. Thus, the weight of the club can be controlled by the user during exercise, such as by controlling the amount of water filled therein. This also eliminates storage and portability challenges due to the size and weight which can be cumbersome, especially in heavier clubs.

[0095]

[0084] In an embodiment, the handle (3) can be shorter compared to the conventional clubs. The studies showed that a longer handle causes tilting and instability in rotational movements. The shorter handle (3) provides more proportional leverage to the user, improves stability and prevents excessive tilting.

[0096]

[0085] The Cap (3A) preferably has an ergonomic shape, with an increasing diameter as it moves away from the end that connects to the handle (3). FIG. 3A illustrates a comparison of a conventional club handle (33), with a ball (33A) at the tip (left) and the handle (33) and the cap (3A) of the disclosed club (A) (right), making the difference evident. FIG. 4 shows the club (A) held by a user at the handle (3) and profile of the grip (3A) comfortably engaging with the hand of the user to prevent slipping of the club.

[0086] The disclosed club (A) can also comprise of a sleeve (4) capable of protecting the club while providing additional padding and security (see FIG. 5). The sleeve can be made of any material commonly used for this purpose, such as but not limited to: neoprene and silicone rubbers. Any other textile or malleable materials can also be used or added as fdler to the neoprene and silicone rubbers. In a preferred embodiment, the sleeve can be 10mm thick to provide adequate protection and padding. Preferably, the sleeve can be permanently attached to the club, either by sewing, glue, or any other suitable means, so that it covers the entire body of the club (A), making it soft and padded for greater comfort, safety, and usability.

[0097]

[0087] In different embodiments, the body of the club (A) can be a single component with the lower portion (1) and the intermediate portion (2) being integral to each other. In another embodiment, the lower portion (1) and the intermediate portion (2) can be two different parts joined together by suitable means known in the art.

[0098]

[0088] In an embodiment, the body comprising the lower portion (1) and the intermediate portion (2), either in a single piece or two different parts, and the cap (3 A) can be injection molded from nylon or similar plastic. When made as two different parts, the lower portion (1) and the intermediate portion (2) can be fused together using an ultrasonic welding process. Welding ensures that the two parts are joined together with high integrity that withstands forces caused when the club is supported and thrown over the shoulder. The handle (3) can then be permanently fixed at the end of the intermediate portion (2) through the threads. The cap (3 A) can be threaded onto the handle (3) in a removable configuration to enable filling of water / sand. The sleeve (4), the soft part that covers the club (A), may also be made using an injection molding process, and then applied to the lower portion (1), the intermediate portion (2) after the two have been assembled / joined by welding.

[0099] EXAMPLES - POSSIBLE EXERCISE SEQUENCES

[0100] Example 1 - Shoulder Roll

[0101]

[0089] The unique ergonomics and proportions of the club, which were achieved after several iterations, allowed for new types of exercises that could not otherwise be performed with the conventional clubs. Successfully executing these movements is enabled by the correct shape of the body of the club as defined by different ratios, herein. Specifically, the defined ratios ensure that the club can be safely rolled over the shoulder and behind the head, while also allowing the user to maintain balance of the club on his body. The shape of frustoconical portions (1 and 2) of the body of the club (A) that is too wide, or a base (i.e., a cylinder) that is too heavy or long, or a taper that is too thin, or diameters that are too small / large, all pose risks to the user while performing these movements incorrectly, potentially causing injury.

[0102]

[0090] FIG. 6 shows the movements performed during the shoulder roll:

[0103] A: club on the right shoulder

[0104] B: rolling over the shoulders / neck area C: rolling over the shoulders / neck area D: club rest on the left shoulder.

[0105]

[0091] It is also possible to combine the shoulder roll with other exercises. For example, FIG. 10 illustrates a shoulder rolling exercise combined with kneeling and upright positions. The user begins from a kneeling position with the club (A) on the right shoulder (FIG. 10A), performing a shoulder roll to place the club (A) on the left shoulder (FIG. 10B). Then the user stands up, placing one foot forward (FIG. 10C), and performs the shoulder roll again, placing the club (A) back to the right shoulder (FIG. 10D). When the club (A) is on his right shoulder, the user kneels back to the starting position.

[0106] Example 2: Rest Position and Shoulder Load for Burst-Based Exercises.

[0107]

[0092] The unique ergonomics and proportions of the club, which were achieved after multiple iterations, allowed the development of a design that positions the device on the user’s shoulder and close to the head to perform exercises of a dynamic and explosive nature (FIG. 7). The unique shape and design provide the user with the functionality of being able to catapult the club off of the body, using the body as a tool for mechanical leverage, with the club resting on the shoulder at point C. This also allows the user to pull the handle down, as shown by arrow A, to lift the opposite end of the club upwards, as shown by the arrow B, to throw the club into the air from his shoulder, so they can continue to exercise with the club. This movement places forces in the middle of the cone and in attaching the handle to the tip of the cone. Without the correct proportions between the intermediate portion and the lower portion, this can prevent the user from completing this movement safely and can also compromise the integrity of the club, as the proportions and ergonomics also needed to structurally reinforce the club.

[0108]

[0093] An example of an explosive / ballistic exercise is illustrated in FIG. 8. For example, from the club on the left shoulder (FIG. 8A), the user can:

[0109] • use the hands to pull the handle down (which causes the lower portion to rise), using the left shoulder as a pivot point and, when the club is in a practically vertical position, with the hands close to the body, the user uses the right shoulder to throw the club (FIG. 8B); • as the club begins to fall, the user takes advantage of the momentum created to rotate the club at the same time as rotating the trunk (FIG. 8C, 8D);

[0110] • the rotation of the trunk and club ends with the club in an upright position, leaning again against the left shoulder (FIG. 8E), and the user then lifts the handle (causing the lower portion to descend: FIG. 8F), using the right shoulder as a pivot point at the same time rotating the trunk back to the starting position (FIG. 8G - FIG. 81);

[0111]

[0094] It is also possible to combine the explosive-based exercise and the shoulder rolling movement, thus forming a more elaborate exercise, as shown in FIGS. 9A-9I. For example, from the club on the left shoulder, the user can:

[0112] • use your hands to pull the handle down (which causes the lower portion to rise), using the left shoulder as a pivot point (FIG. 9H);

[0113] • when the club is in a roughly upright position, with the hands close to the body, the user uses the left shoulder to throw the club;

[0114] • as the club begins to fall, the user takes advantage of the momentum created to rotate the club toward the right shoulder (FIGS. 91, 9A, 9B, and 9C);

[0115] • the rotation ends with the club in a vertical position, leaning against the right shoulder, and the user then lifts the handle (causing the lower portion to descend), using the right shoulder as a pivot point (FIG. 9D);

[0116] • from then on, the user can perform the shoulder roll again to place the club on the left shoulder and repeat the movement (FIG. 9E to FIG. 9G).

[0117]

[0095] FIGS. 11A-11G illustrate the steps of the simple club throw associated with a step back movement. The starting position corresponds to the user with the club on one of the shoulders (FIG. 11 A). From there, he takes a step back at the same time as lowering the handle and throwing the club forward with his shoulder (FIG. 1 IB). The club then makes a pendulum motion (FIG. 11C to FIG. HE), then returns to the same shoulder that threw it (FIG. 1 IF). The user takes a step forward, thus returning to the starting position (FIG. 11G).

[0118]

[0096] FIGS. 12A-12J illustrate a movement that combines forward club tossing and shoulder rolling. Starting from a starting position, where the user is standing still, with the feet parallel and the club on the right shoulder, the user throws the club forward with the help of the shoulder, holding it so that the club performs a pendulum movement (FIG. 12A), the club then returns to the same shoulder (FIG. 12B to FIG. 12D), and then the user performs the shoulder roll (FIGS. 12E, 12F), positioning the club on the left shoulder, and then throwing the club with the left shoulder (FIG. 12G), which will perform the pendulum movement (FIG. 12H to FIG. 12J), returning back to the left shoulder.

[0097] FIGS. 13A-13L show a movement that combines the throw with pendulum movement, with shoulder rolling and 180° turning. Starting from an initial position, where the user is standing with one foot in front of the other, and the club on the right shoulder, the user throws the club forward with the help of the shoulder, holding it so that the club performs a pendulum movement, returning to the same shoulder (FIG. 13 A to FIG. 13C). The user then performs a shoulder roll while rotating the body 180° (FIG. 13D to FIG. 13H). At the end of the turn, with the club on his shoulder, the user throws the club forward with the help of the shoulder, holding it so that the club performs a pendulum movement (FIG. 131 to FIG. 13L). Similarly, the club returns to the shoulder and the user then performs a shoulder roll while rotating the body 180°, thus returning to the starting position.

[0119]

[0098] Thus, the present invention provides an improved exercise club that is ergonomically designed taking into account specific human anatomy and shape (e.g., the back, trapezius, shoulders, etc.) to allow the user to leverage these parts of the body as a tool to be used in conjunction with the club’s proportions. The ergonomically designed improved club enables a range of exercises with comfort and safety for the user.
