Description

[Technical Field]

[0001] The present invention relates to a lightweight and portable training tool that can be used to perform stretching / strength training for the hamstrings, quadriceps, latissimus dorsi, hip joints, etc., and also to train the area around the shoulder blades to increase the range of motion of the shoulder blades, stretching the entire body, both upper and lower, and improving muscle strength and flexibility. [Background technology]

[0002] Conventionally, stationary training devices have been common as muscle training tools, and various muscle training devices have been proposed, but portable training devices have also been proposed. For example, Patent Document 1 discloses various training devices with relatively simple structures for strengthening muscles such as the latissimus dorsi and hamstrings, and improving flexibility.

[0003] In Patent Document 1, for example, a training device 100 for training the latissimus dorsi muscles is configured as shown in FIG. 11(a) attached to the present application, in which a user sits on a seat 113, grasps a handle 121 with both hands, and moves the handle 121 downward. At this time, the coil spring of the load section 130 stretches, creating a load on the handle 121, so the user must apply force to both arms in accordance with the load. When the user releases the force, the holding force of the coil spring of the load section 130 returns the handle 121 to its original position. The above steps are repeated a predetermined number of times at a predetermined speed. With such a device, it is believed that a user can train the latissimus dorsi muscles and the like.

[0004] Furthermore, in Patent Document 1, for example, a training device 200 for training hamstrings has the configuration shown in FIG. 11(b) attached to the present application, in which a user sits on a seat 213, places both feet on a foot placement section 221, and slides an operating section 220 upward with both feet. At this time, the coil spring of the load section 230 stretches, generating a load on the operating section 220, so the user must apply force to both legs in accordance with the load. When the user releases the force on their legs, the holding force of the coil spring of the load section 230 returns the operating section 220 to its original position. The above steps are repeated a predetermined number of times at a predetermined speed. With such a device, it is believed that a user can train muscles such as hamstrings.

[0005] On the other hand, Patent Document 2 describes a portable training tool. As shown in FIGS. 12(a) and 12(b), the training tool 300 described in Patent Document 2 includes a pair of arms 322a and 322b each made of an elongated member 320 that is inelastic and flexible, such as made of nylon fiber. An anchor 310 is attached to one end of each of the arms 322a and 322b, and the arms 322a and 322b are configured to be attachable to a structure such as a door or a pole using the anchor 310. Meanwhile, grips 323a and 323b are provided at the other end of each of the arms 322a and 322b, respectively, and a user can perform various training exercises using the grips 323a and 323b.

[0006] For example, as shown in Figure 13(a), a user holds the grip pair 323a, 323b with their hands, places their feet at a horizontal distance X from anchor point A, and holds them in a direction away from anchor point A (direction E), with part of their weight supported by the equipment. By changing the amount of weight supported, the user can perform so-called high-row arm training. Also, as shown in Figure 13(b), the user can perform so-called recumbent curl training by lying on the floor with their feet hooked between the grip pair 323a, 323b.

[0007] [Patent Document 1] Utility Model Registration No. 3163268 [Patent Document 2] Special Publication No. 2010-538767 Summary of the Invention [Problem to be solved by the invention]

[0008] As described above, in order to increase muscle strength and flexibility, the training device described in Patent Document 1 requires the preparation of multiple training devices 100, 200 with different structures corresponding to the body parts to be trained, such as the latissimus dorsi and hamstrings. These devices are large and rigid, and assembling them requires a lot of time and money. Furthermore, the assembled devices themselves are either impossible or extremely difficult to transport. Therefore, installing these various training devices requires the preparation of large-scale training facilities. Furthermore, the various training devices described in Patent Document 1 use load units such as coil springs, which may, in some cases, place excessive loads on muscles, knees, hip joints, etc., potentially resulting in injury.

[0009] On the other hand, the training tool 300 described in Patent Document 2 has the advantage of being portable and not requiring the preparation of special training facilities, but it involves training using both hands or both feet on grip pairs 323a, 323b and applying part of the body weight, and therefore it cannot be said to be sufficient for stretching / strength training of the hamstrings, quadriceps, latissimus dorsi, hip joints, etc., or for increasing the range of motion of the shoulder blades and stretching the entire body, both upper and lower, to improve muscle strength and flexibility.

[0010] Therefore, the present invention has been made to solve the problems associated with the conventional training tools described in the above Patent Documents 1 and 2.

[0011] The main object of the present invention is to provide a lightweight, portable training tool that allows the user to perform stretching / strength training of the hamstrings, quadriceps, hip joints, etc. using their own body weight, increases the range of motion of the shoulder blades, stretches the entire body, both upper and lower, and improves muscle strength and flexibility.

[0012] Another object of the present invention is to provide a training tool that does not place excessive strain on training areas such as the hamstrings, quadriceps, and hip joints, and that can prevent injuries during training.

[0013] Another object of the present invention is to provide a training tool that can be used easily to train relatively large muscles such as the hamstrings and quadriceps without requiring a large training machine or a specialized training room, and that is lightweight and easy to carry. [Means for solving the problem]

[0014] The above object is achieved by the training device of the present invention. Insert thigh area surroundings Can be attached to It is said to be the size a main body having two ring portions and a connecting portion connecting the two ring portions; and a fixing portion for attaching the main body to an existing structure; With death, The ring portion is formed in a ring shape from a wide band-like body that is flexible in the longitudinal direction and the width direction but is non-stretchable in the width direction and the longitudinal direction, The wide band-shaped body forming the annular ring portion is a band-shaped member having an inner diameter (D2) of 125 to 435 mm and a width (W) of 80 to 150 mm when in a circular shape. This is a training tool characterized by the above.

[0015] According to one embodiment of the present invention, a cushion portion is provided at least in a predetermined length region of the ring portion opposite to the connecting position between the ring portion and the connecting portion.

[0017] According to another embodiment of the present invention , the wide band forming the annulusis made of a flexible but non-stretchable wide, elongated member that may be one or more layers. It has been , The cushion portion is formed by incorporating a cushioning material inside the wide band, or by surrounding the outer periphery of the wide band.

[0019] According to another embodiment of the invention, the connector is formed of a wide strip made of one or more layers of flexible but non-stretchable wide elongated material.

[0021] According to another embodiment of the present invention, the wide strip is a woven or knitted fabric made of polyamide fibers or polyester fibers, either alone or in combination.

[0022] According to another embodiment of the present invention, the fixed portion has a belt member made of a flexible but non-stretchable string-like elongated member, and the belt member is held by the connecting portion. [Effects of the Invention]

[0023] The training tool of the present invention comprises: (1) The device allows users to stretch and strengthen their hamstrings, quadriceps, hip joints, and other training areas using their own body weight without having to worry about tipping over or the center of gravity. It also increases the range of motion of the shoulder blades, stretching the entire body, both upper and lower, making it easy to shift weight and allowing for two-person stretching without help, improving muscle strength and flexibility. It is also lightweight and portable. (2) Because the load on the training area is your own body weight, excessive load is not placed on the training area, which helps prevent injuries during training. (3) You can focus your attention on the hamstrings, which are one of the muscles that are difficult to focus on, and you can train them in a short amount of time. (4) It allows for training of the lower body, which has weakened muscles, with less strain on the knees and hips, and can be used intermittently even during rehabilitation. (5) Strengthening the hamstrings dramatically improves basic movements in exercise or sports, such as running, jumping, throwing, and hitting, which in turn strengthens the body structure. (6) Although it trains relatively large muscles in the body, such as the hamstrings and quadriceps, it can be easily performed without requiring large training machines or a specialized training room, and is lightweight and easy to carry. The following effects can be achieved. [Brief explanation of the drawings]

[0025] The training tool according to the present invention will be described in more detail below with reference to the drawings.

[0026] Example 1 FIG. 1(a) is a schematic plan view illustrating the basic configuration of a training tool 1 according to the present invention, and FIG. 1(b) is a perspective view showing the outline of the configuration of one embodiment of the training tool 1 according to the present invention.

[0027] In this embodiment, the training device 1 according to the present invention includes a main body 1A having two pairs of ring-shaped ring portions 2 (2a, 2b) and a connecting portion 3 connecting the two ring portions 2a, 2b, as shown in FIG. 1(a). Each ring portion 2a, 2b has the same shape and structure and is sized so that it can be inserted around the thigh region of a user using the training device 1 and worn. Therefore, each ring portion 2a, 2b is sized so that it can be worn around one shoulder region by inserting an upper limb through the ring portion 2a, 2b. Each of the two ring portions 2a, 2b may have a circular shape with an inner diameter D2. In this embodiment, the two ring portions 2a, 2b may be provided with an elastically deformable cushion portion 4 in a region opposite the joining position F with the connecting portion 3, as will be described in detail later. Even if the cushion portion 4 is provided, the ring portions 2a, 2b are sized so that the user can insert the lower limb and wear the ring portion 2a, 2b around the thigh region. The inner diameter D2 formed by the substantially circular ring portions 2a and 2b is, as shown in FIG. 1(a), 125 to 435 mm (specifically, D2=290 mm in this embodiment).

[0028] Furthermore, as shown in FIG. 1(a), the training tool 1 is provided with a fixing part 20 for connecting and attaching the main body part 1A to a structure P (see FIG. 5(b)), such as an existing fixed pole. In this embodiment, the fixing part 20 is an elongated string-like member (referred to as a "belt member" in this specification) 21 such as a belt or rope, which is passed through a belt loop formed in the connecting part 3, i.e., a belt holding part 5, and is held movably relative to the connecting part 3. The connecting part 3 and the fixing part 20 will be described again later in connection with the explanation of the manufacturing method of the training tool 1.

[0029] Next, the training tool 1 according to the present invention will be described in more detail with reference to the embodiment shown in FIG. 1(b).

[0030] In this embodiment, each of the loop portions 2a, 2b forming the main body 1A is formed into a ring shape from a wide band 10 that is flexible but inelastic, i.e., non-stretchable. In this embodiment, the wide band 10 is a wide, elongated member having a width W of 80 to 150 mm and a thickness T2 of 1 to 3 mm (specifically, in this embodiment, the width W = 100 mm and the thickness T2 = 1.3 mm), and is made by laminating one or more layers of flexible but instretchable material. In other words, the wide band 10 is flexible in the longitudinal and width directions and can be bent and deformed, but has substantially no stretchability in the width and longitudinal directions, i.e., is a non-elastic member. In this embodiment, if the width W of the wide band 10 is less than 80 mm, as described below, the load applied to the user's thigh muscles, such as the hamstrings and quadriceps, becomes localized during use. This increases the load per unit area, resulting in excessive load on the thigh muscles and potential muscle damage. On the other hand, if the width W exceeds 150 mm, the load applied to the hamstrings and quadriceps, etc., by the user's body weight becomes weak. This decreases the load per unit area, resulting in insufficient training of the thigh muscles. Furthermore, as described below, the ring portions 2a and 2b can be grasped by hand to enable training around the scapulae, for example. However, if the width W exceeds 150 mm, the width W becomes too wide, potentially making it difficult to grasp the ring portions 2a and 2b, particularly the cushion portions 4 of the ring portions 2a and 2b. Of course, the wide band 10 must have enough strength (breaking strength) to withstand a load of approximately the user's weight (maximum 200 kg) when using the training equipment. As will be described in detail, the wide band 10 is preferably made of woven or knitted fabrics made of synthetic fibers, natural fibers, or blends thereof. In particular, in this embodiment, woven fabrics made of synthetic fibers are preferably used, and the non-stretchable material is a woven or knitted fabric made of synthetic fibers such as polyamide fibers such as nylon 6 and nylon 66, or polyester fibers such as polyethylene terephthalate and polybutylene terephthalate, either alone or in combination.In this example, specifically, a non-stretchable synthetic woven fabric made of polyester fiber manufactured by TM Vu Hung Co., Ltd. was used.

[0031] The connecting portion 3 is preferably, but not limited to, a wide band 10 similar to the ring portion 2 (2a, 2b) and fabricated integrally with the ring portion 2, as shown in the drawings and described below. Therefore, in this embodiment, a wide band 10 similar to the ring portion 2 (2a, 2b) is used, and the width W3 is the same as the width W of the ring portion 2, i.e., W3 = W = 80 to 150 mm (specifically, W3 = W = 100 mm in this embodiment). However, the thickness T3 can be set to T2 = 1 to 3 mm, similar to that of the ring portion 2. However, in this embodiment, the thickness T3 is set to T3 = 3 × T2 for manufacturing reasons, as described below. The wide band 10 is flexible but non-stretchable. That is, the wide band 10 of the connecting portion 3 is also flexible and can be bent and deformed, but does not substantially stretch in the width or longitudinal directions, i.e., it is a non-elastic member. Furthermore, the length L3 of the connecting portion 3 is set to 10 to 30 cm (specifically, 190 mm in this embodiment), although it is not limited thereto, in order to connect the ring portions 2 (2a, 2b) at an appropriate interval and hold the fixed portion 20, which is a belt member 21 as described below, making it suitable for use as an exercise tool.

[0032] As described above, in this embodiment, the two ring portions 2a, 2b of the training device 1 of the present invention each have a cushion portion 4, as shown in FIGS. 1(a) and 1(b). The cushion portion 4 is integrally provided on the ring portions 2a, 2b over a length L4 in the region (load region) that directly contacts and presses against the thigh of the lower leg when the thigh region is attached to the ring portions 2a, 2b through the lower leg, i.e., the region opposite the junction F with the connecting portion 3. This reduces discomfort upon contact with the muscle and protects the muscle from damage due to unexpected excessive loads. Of course, the cushion portion 4 may also be provided around the entire inner periphery of the ring portions 2a, 2b. In this embodiment, the region length L4 of the cushion portion 4 is 50 to 530 mm, specifically, 380 mm. The cushion portion 4 will be described again later in connection with the manufacturing method of the training device 1.

[0033] Furthermore, as described above, the training tool 1 has a fixing part 20 that connects the connecting part 3 to a structure P (see FIG. 5(b)), such as an existing fixed pole, to hold the main body 1A. In this embodiment, the fixing part 20 has a flexible, elongated belt member 21 made of, for example, a synthetic fiber fabric, such as a belt or rope, and the belt member 21 is passed through a belt member holding part, i.e., a belt loop 5, formed on the connecting part 3, and is held movably relative to the connecting part 3. The belt holding part 5 will be described again later in connection with the explanation of the manufacturing method of the training tool 1.

[0034] One end 21a of the belt member 21 is equipped with a buckle (fastening metal fitting) 22 having two D-shaped ring fittings 22a, 22b, and as shown in Figures 5(a) and (b), the other end 21b of the belt member 21 is passed through it, allowing the usable length of the belt member 21 to be adjusted and fixed. That is, the end 21b of the belt member 21 passes through the holes of the D-shaped ring fittings 22a, 22b of the buckle 22, then turns back and passes around the outside of fitting 22a, passes through the hole of fitting 22b, and then the length of the belt member 21 is adjusted and the end 21b of the belt member 21 is pulled to tighten and fix it. Instead of the belt member 21 configured as above, it is also possible to use a rope as the fixing part 20, for example, with a hook attached to the end thereof so that it can be connected and fixed to an existing structure P.

[0035] Preferably, an elongated pad member 30 is attached to the belt member 21 so as to be movable along the longitudinal direction of the belt member 21, as shown in FIGS. 1(a) and 1(b) and FIGS. 4(a) and 4(b), which will be described later. This pad member 30 functions as a friction member to prevent the belt member 21 from shifting when it is connected to a structure P, such as a pole, and also to prevent damage to the pole. Any suitable pad member 30 can be used and is not limited to the one described below. In this embodiment, first and second pad members 30A and 30B were used, each having a pad material 31b integrally formed on one side of a base material 31a by stitching or the like. The first and second pad members 30A and 30B have the same widths W30A and W30B, but the lengths L30A and L30B of the first pad member 30A are slightly longer (L30A > L30B). In addition, both ends of the first pad member 30A are formed in a curved shape in this embodiment, although this is not essential. In this embodiment, the base material 31a of the pad member 30 (30A, 30B) is the same synthetic fiber fabric as used for the wide belt 10, and the pad material 31b is, for example, a stretchable polyurethane resin pad material. Although not limited thereto, in this embodiment, the widths W30A, 30B are W30A = 30B = 65 mm, and the lengths L30A, L30B are L30A = 190 mm, L30B = 140 mm.

[0036] The two members 30A, 30B are integrated with each other by stitching S30 at both longitudinal edge portions with the base materials 31a facing each other, thereby allowing the belt member 21 to be movably inserted and attached through a central slot G30 formed extending in the longitudinal direction.

[0037] 1(a) and 1(b), the belt member 21 is a string-like elongated member having a width W21 of 30 to 100 mm, a thickness T21 of 1 to 3 mm, and a total length L21 of 600 to 2400 mm (specifically, in this embodiment, the width W21 is 50 mm, the thickness T21 is 1.3 mm, and the total length L21 is 1200 mm). The belt member 21 is an inelastic and flexible member, i.e., it is bendable and flexible but not stretchable. Of course, it must be strong enough to withstand a load equivalent to the user's weight (maximum 200 kg) imposed when using the training equipment. A synthetic fiber woven fabric is preferably used as the base material for the string-like elongated member. As described above, the same non-stretchable synthetic fiber woven fabric as the wide band-like members forming the loop portion 2, the connecting portion 3, etc. can be preferably used.

[0038] (Manufacturing method) Next, one embodiment of a method for manufacturing the training tool 1 according to the present invention will be described with reference to FIGS. 2(a) to 2(c).

[0039] In this embodiment, as shown in FIG. 2(a), the training tool 1 according to the present invention is prepared by folding a non-stretchable strip-shaped material 11 having a width W0 and a length L0 in the longitudinal direction and cutting it to a predetermined elongated width (W) and length (L) to produce an outer layer 11a and a lining layer 11b made of a non-elastic material. The outer layer 11a and the lining layer 11b are stitched (sewn) S10 along the longitudinal direction, for example, at positions approximately 3 to 5 mm from both end edges, to produce a wide strip 10. In this embodiment, the wide strip 10 has a two-layer structure consisting of the outer layer 11a and the lining layer 11b, but it can also have a three-layer or more layer structure. Of course, a single-layer structure is also acceptable. Furthermore, while the outer layer 11a and the lining layer 11b are made of the same material in this embodiment, this is not limiting, and different materials can also be used for each layer.

[0040] 2(b), a narrow wide strip 10 having a predetermined width (W) and length (L) is folded into a loop, and the regions of both end portions 10A, 10B of the wide strip 10 having a length L3 are directly overlapped to form the region of the connecting portion 3. Next, the wide strip 10 is shaped so that loop portions 10C, 10C having a length L2 are formed on both sides of the overlapped end portions 10A, 10B. Next, the center portion 10D of the wide strip 10 having a length L3 and the region of the connecting portion 3 having a length L3 formed by the end portions 10A, 10B are overlapped, and stitching processing S3 is performed. 2(c) and 1(a), a main body 1A of the training tool 1 is produced, which has two paired ring portions 2a, 2b with a diameter D2 formed in a ring shape from the wide band 10, and a connecting portion 3 with a length L3 connecting the two ring portions 2a, 2b. However, in this embodiment, the connecting portion 3 with length L3 is made of three layers of wide band 10, which increases its strength (load capacity).

[0041] Next, a method for manufacturing the cushion portion 4 will be described. In this embodiment, as described above, the wide strip 10 is produced by sewing together the outer fabric 11a and the lining fabric 11b, which are made of an elongated rectangular inelastic material cut to a predetermined width (W) and length (L). In this embodiment, the cushioning material 6 can be inserted between the outer fabric 11a and the lining fabric 11b in the load-bearing region (i.e., the cushion portion 4) of length L4, as shown in FIG. 3(a), and the outer fabric 11a and the lining fabric 11b can be sewn together by sewing together, incorporating the cushioning material 6. A cushion portion 4 having a length L4 and a thickness T4 of approximately 10 to 100 mm (see FIG. 3(a)) and incorporating the cushioning material 6 can be produced. Various materials can be used as the cushion material 6, such as a high-density polyurethane foam. In this example, a high-density foam was used, processed to a diameter D4 of 50 mm and a length L4 of 380 mm, as shown in FIG. 3(a), and inserted into the region of the cushion section 4 having the length L4. Of course, the structure of the cushion section 4 is not limited to the above structure. As shown in FIG. 3(b), a cylindrical cushion material 6 can also be inserted around the wide band 10, surrounding the outside of the wide band. Furthermore, although not shown, an elongated or flat cushion material 6 can also be wrapped around the outside of the wide band 10.

[0042] Furthermore, as shown in FIGS. 1(b) and 2(c), in this embodiment, the training tool of the present invention has a belt loop (belt holding portion) 5 formed in the connecting portion 3, which has a length L3. The belt holding portion 5 is preferably formed, for example, from the same base material 11 as that used to form the belt-shaped member 10, as shown in FIG. 2(c). However, in this embodiment, the width W5 is approximately 20 to 40 mm smaller than the width W3 of the connecting portion 3, and the length L5 is 50 to 150 mm. Specifically, in this embodiment, the width W5 is 50 mm and the length L5 is 90 mm. Both longitudinal ends of the belt holding portion 5 are stitched S5 to the connecting portion 3, and a gap G5 (see FIG. 1(a)) is formed between the belt holding portion 5 and the connecting portion 3. Therefore, the belt member 21 is freely movable along the longitudinal direction of the belt, perpendicular to the longitudinal direction of the connecting portion 3. However, the width WG5 of gap G5 (see FIG. 1(a)) is set to a gap width that allows only slight movement of belt member 21 in the longitudinal direction of connecting portion 3 (i.e., toward loop portions 2a and 2b), and does not substantially cause misalignment. In other words, gap width WG5 is set to be slightly larger than belt width W21, for example, by about 2 to 3 mm. This belt holding portion 5 also has the function of connecting belt member 21 to a structure P such as a pole and preventing the holding positions of belt member 21 and structure P from shifting when training tool 1 is used with a load applied to it, thereby stably holding training tool 1 to structure P.

[0043] The training tool 1 according to the present invention configured as described above has a weight of, for example, about 350 g for the main body 1A including the loops 2 (2a, 2b) and the connecting portion 3, and about 160 g for the fixing portion 20. Furthermore, by folding it, it can be stored in a bag measuring about 440 mm in length and 330 mm in width, making it lightweight and easy to carry. Furthermore, the training tool configured as described above in this example was able to withstand a load of 135 kg or more.

[0044] (How to use) Next, we will explain the training methods that can be carried out using the training tool of the present invention. Using the training tool of the present invention configured as described above, for example, the following training can be carried out, but of course, the use of the training tool of the present invention is not limited to these training methods.

[0045] First, before using the training tool 1, the fixing portion 20 of the training tool 1 is connected to a structure P, such as a fixing pole, to set up the training tool 1. That is, as shown in FIGS. 1( a) and 1(b), the belt member 21, which has been passed through the belt holding portion 5, is turned to the opposite side of the connecting portion 3 from the belt holding portion 5, and is then wrapped around the structure P, such as a fixing pole, so that the cushion portion 30 comes into contact with the structure P, as shown in FIGS. 5(a) and 5(b). Next, one end 21b of the belt member 21 is passed through a hole in a buckle metal fitting 22 provided on the other end 21a, folded back, and fastened, firmly connecting both ends 21a, 21b of the belt member 21. In this way, the training tool 1 is attached to the structure P. Next, the user can use the training tool 1 to perform the training they require, as described below. (1) Hamstring stretching and training (Figure 6(a)-(c)) The user inserts their lower legs into the two ring portions 2 (2a, 2b) of the training tool 1, with the front thigh regions of their lower legs facing the cushion portions 4 of the ring portions 2 (2a, 2b) (Fig. 6(a)). Next, they place the ring portions 2 (2a, 2b) of the training tool 1 above their knees, stretch them taut, and bend their hip joints (Fig. 6(b)) without bending their waist, and bend their body forward in an "U" shape and pull (Fig. 6(c)). Then, they slowly stand up. (2) Quadriceps training (Figure 7(a) and (b)) The user inserts their lower legs into the two ring portions 2 (2a, 2b) of the training tool 1 so that the posterior thigh regions of their lower legs come into contact with the cushion portions 4 of the ring portions 2 (2a, 2b) (Fig. 7(a)). Next, they place the ring portions 2 (2a, 2b) of the training tool 1 behind their knees, stretch them taut, drop their buttocks diagonally downward, and bend their hip joints (Fig. 7(b)). Then, they slowly stand up. (3) Stretching both latissimus dorsi muscles (Figure 8(a) and (b)) The user positions themselves facing the training tool 1, raises the training tool 1 to arm height, and grasps the ends (cushion parts 4) of the two loop parts 2 (2a, 2b) of the training tool 1 with both hands (Fig. 8(a)). Next, the user shifts their center of gravity to their heels, bends their body into a "L" shape, and pulls (Fig. 8(b)). Then, they slowly return to their original position. (4) Unilateral latissimus dorsi stretch (Figure 9(a) and (b)) The user positions themselves sideways in relation to the training device 1 and grasps the ends (cushion portions 4) of the two loop portions 2 (2a, 2b) of the training device 1 with both hands (Fig. 9(a)). Next, the user raises the training device 1 to arm height and grasps the ends (cushion portions 4) of the two loop portions 2a, 2b of the training device 1 with both hands. Next, the user shifts their center of gravity to their right leg, bending their body in a "L" shape so that their right upper limb is positioned above their left upper limb and pulling (Fig. 9(b)). Then, they slowly return to their original position. If necessary, the same training can be performed in the opposite direction, i.e., with their left upper limb positioned above their right upper limb. (5) Stretching around the shoulder blades (Figure 10(a)~(c)) The user positions themselves facing backwards in relation to the training tool 1 and inserts their upper limbs into the two rings 2 (2a, 2b) of the training tool, placing the cushioning 4 of each ring 2 (2a, 2b) against the front region of their shoulders (Fig. 10(a)). Next, with the cleaning tool 1 on their back, they bring their shoulder blades in toward their spine, stick out their chest, and lean forward (Fig. 10(b)). Next, they imagine there is a wall in front of them, cross their arms, and push against it, using the momentum of the push to return their upper body to the original position (Fig. 10(c)).

[0046] As described above, the training tool according to the present invention, which is configured as described above and can be used by a user for physical training, comprises: (1) The device allows users to stretch and strengthen their hamstrings, quadriceps, hip joints, and other training areas using their own body weight without having to worry about tipping over or the center of gravity. It also increases the range of motion of the shoulder blades, stretching the entire body, both upper and lower, making it easy to shift weight and allowing for two-person stretching without help, improving muscle strength and flexibility. It is also lightweight and portable. (2) Because the load on the training area is your own body weight, excessive load is not placed on the training area, which helps prevent injuries during training. (3) You can focus your attention on the hamstrings, which are one of the muscles that are difficult to focus on, and you can train them in a short amount of time. (4) It allows for training of the lower body, which has weakened muscles, with less strain on the knees and hips, and can be used intermittently even during rehabilitation. (5) Strengthening the hamstrings dramatically improves basic movements in exercise or sports, such as running, jumping, throwing, and hitting, which in turn strengthens the body structure. (6) Although it trains relatively large muscles in the body, such as the hamstrings and quadriceps, it can be easily performed without requiring large training machines or a specialized training room, and is lightweight and easy to carry. It has the following features. [Explanation of symbols]
