Description

The present invention relates to a smart exercise device capable of measuring muscle strength in real time. More specifically, the present invention relates to a smart exercise device capable of measuring muscle strength in real time, which not only enables a user to perform various exercises that can be performed at a fitness center, etc., with one device, but also allows the user to perform progressive overload exercises with a load that is suitable for the user, as the user's muscle strength is measured and displayed in real time while exercising, and allows systematic exercise management, such as recommending exercises for relatively weak parts/parts that need exercise based on the exercise data after exercise. The present invention relates to a smart exercise device capable of measuring muscle strength in real time, which not only enables a user to perform various exercises with different muscle strength, but also recommends an elastic band with the most appropriate elasticity according to the user's muscle strength and guides the user to exercise in the optimal environment.

Typically, strength training is performed using exercise equipment that gives a sense of weight, such as weight equipment or elastic bands. However, this simply involves repeating strength training against a given weight and does not have a measurement function to measure the user's muscle strength in real time while exercising. This creates the problem that it is not possible to perform personalized exercises according to the user's muscle strength, and after exercise, it is not possible to systematically manage muscle strength data by body part and date, such as which muscles have grown and how much.

In addition, strength exercises develop muscles through the principle of progressive overload, which means slowly increasing the weight you handle each time. However, existing weight equipment determines the weight according to the blocks inserted into the equipment, so weight can be increased in increments of 2.5kg, 5kg, and 10kg, which is the weight of the unit block. This means that it is difficult to achieve progressive overload such as 20kg, 20.1kg, 20.3kg, and 20.5kg, and it is not possible to increase weight from 20kg to 22.5kg immediately. In addition, existing exercise equipment has the problem of requiring separate, expensive dedicated machines for each type of exercise, which is costly and requires a lot of installation space.

In addition, elastic bands made of relatively inexpensive rubber are sometimes used at home, but depending on the type of exercise, in some cases the band must be held short while sitting and standing up, and in other cases the band must be held long while lifting the arm over the shoulder. However, conventional elastic bands are made entirely of rubber, and as the length of the band changes, the pulling force also changes. For example, when the elastic band is held short, it can be stretched to the same length by pulling with a large force, whereas when held long, it can be stretched to the same length with only a little force. This causes the exercise load to change significantly every time the posture is changed, which can make it difficult to exercise properly.

In addition, existing elastic bands are provided in several colors, such as yellow, red, blue, purple, and black, with different elasticity, and people often combine multiple bands for each type of exercise to suit their muscle strength. However, even for the same person, muscle strength varies for over 30 types of exercise, making it very difficult to know which bands to use and how many to combine. As a result, people are often unable to use bands appropriate for each type of exercise, and end up using a combination of bands that are too hard or too weak, which often results in complaints that they are not getting the exercise they need.

The present invention is intended to solve the above-mentioned problems, and provides a smart exercise device that can measure muscle strength in real time, allowing users to perform various exercises that can be performed at fitness centers, etc., with one device, and that measures and displays the user's muscle strength in real time while exercising, allowing users to enjoy progressive overload exercise with a load that suits them. After exercise, systematic exercise management is possible, such as recommending exercises for relatively weak parts/parts that need exercise based on the exercise data. In addition, even if the user is exercising in various types of exercises with different muscle strength, the device recommends an elastic band with the most appropriate elasticity according to the user's muscle strength, and provides guidance to always exercise in the optimal environment.

As shown in FIG. 1, in the first embodiment of the present invention, when the user performs muscle exercise while pulling the strap 25, the muscle strength of the user detected by the sensor is displayed in real time through the display window 13a of the device itself or the screen of the external display means 40 such as a smartphone, computer, or television, so that the user can visually check their muscle strength and perform gradual overload exercise with an exercise load suitable for them. In other words, if you lift up to 20 kg today, you can perform gradual overload exercise such as 20.1 kg tomorrow and 20.3 kg the day after tomorrow. Not only can you perform gradual overload exercise, but you can also manage systematic data such as the progress of muscle strength increase by exercised part after exercise, and you can perform recommended exercises for relatively weak parts or parts that need exercise for the next exercise, making systematic muscle exercise possible even for beginners.

As shown in Figs. 3 to 5, the present invention provides a turntable 18 that can rotate left and right around a second axis 17 on a support means 10, a vertical rotating bracket 14 is provided on the turntable 18, and a rotating support 15 that rotates up and down around a horizontal first axis 16 is provided on the upper end of the rotating bracket 14, and a first sensor 12 for detecting muscle strength is connected to the rotating support 15 via a bolt or the like. Therefore, the first sensor 12 rotates up, down, left and right around the first axis 16 and the second axis 17, and is positioned perpendicular to the pulling force regardless of the direction in which the strap 25 is pulled, and can accurately detect the pulling force. In other words, while some exercises involve pulling upwards, there are also exercises involving spreading left and right and exercises involving pulling diagonally, and exercises are performed in various directions, so it is a very important technology to be able to accurately detect the force regardless of the direction in which the strap 25 is pulled.

In some cases, as shown in FIG. 3, a ball plunger 18a is provided on the support means 10 with a ball exposed to the outside and supported by a spring, and a number of ball seating grooves 18b are provided at a certain angle on the turntable 18 at a position corresponding to the ball plunger 18a, so that the user can move the sensor bundle A in the desired direction according to the angle.

The first shaft 16 or the second shaft 17 has an axial hole 19, 20 that runs through the center like a pipe, and the signal line 21 and power line of the first sensor 12 are wired to the outside through this axial hole 19, 20. No matter in which direction the first sensor 12 rotates to detect muscle force, the signal line 21 and power line are protected inside the shaft, so signals can be transmitted safely without being broken.

In the first embodiment of the present invention, a sensor bundle A, which is usually a combination of a length adjustment means 30, a first sensor 12, a turntable 18, a rotating support 15, etc., is provided in pairs at both ends of the support means 10 as shown in FIG. 1, and is connected to both handles 29 or both ends of a barbell bar, allowing exercise with both hands. At this time, the screen of the display means 40 in FIG. 1 is provided with a balance confirmation section 44 that can check the balance of strength by comparing the user's left and right muscle strength, allowing the user to perform balanced muscle exercise while checking the state of their own left and right balance in real time during exercise.

2(a)-(c), even if the length of the strap 25 is adjusted according to the exercise posture, such as by holding the strap 25 short or long according to the type of exercise, the elastic part 26 always maintains a constant length and elasticity, so that muscle exercise can be performed with a constant exercise load, and the planned exercise can be performed with uniform resistance since there is no problem of imbalance in exercise load, such as the strap 25 being easily or difficultly stretched due to the length of the elastic part changing according to the exercise posture as in the past. Incidentally, the length that the user stretches with their legs bent and the length that the user stretches with their arms folded are almost the same, so if the elasticity is the same, they can exercise with a constant exercise load.

In addition, the elastic portion 26 of the strap 25 is provided with a number of elastic bands 28 with different elasticity as shown in FIG. 6, and one or more of the elastic bands 28 are detachably connected to the length adjustment portion 27. Since the user exercises different muscles for each type of exercise, elastic bands 28 with high elasticity should be used for large muscles such as the pectoral muscles, and elastic bands 28 with low elasticity should be used for relatively small muscles such as the deltoid muscles. In this way, it is not difficult for a beginner to find the elastic band 28 that is suitable for each type of exercise.

Accordingly, the present invention calculates the elastic band 28 with the most suitable elastic force (or the closest elastic force) for the muscle based on the muscle strength detected by the first sensor 12, and recommends it to the user through the band recommendation unit 42 on the screen of the display means 40. Therefore, the user can select and use the elastic band 28 that is most suitable for him/herself very easily by simply connecting the recommended elastic band 28 to the strap 25, even if the user is a beginner. For example, when the elastic bands 28 are displayed in yellow, red, blue, purple, and black for 1 kg, 3 kg, 5 kg, 10 kg, and 20 kg, respectively, if the user measures the muscle strength of the deltoid muscle to be 8.3 kg, the method is such that the closest elastic bands 28 are recommended to be connected to the strap 25, one each of blue and red.

In addition, the present invention provides an exercise result display unit 43 on the screen of the display means 40 that shows the degree of muscle strength increase or decrease for each part of the human body structure after the exercise is completed, allowing the user to very easily understand at a glance how much muscle strength has increased in each part. Furthermore, the screen of the display means 40 further includes an exercise type recommendation unit 45 that recommends focusing on parts with a low rate of muscle strength increase or parts that need exercise based on the exercise results, which is advantageous in that even non-experts can exercise systematically.

In addition, even if the strap 25 of the present invention applies the same exercise load when exercising at the same length, if the strap 25 is pulled a little further today than yesterday, an increased load is applied, making gradual overload exercise very easy to perform.

In addition, a handle 29 is detachably connected to the upper end of the strap 25, and the handle 29 has multiple gripping parts 29a spaced apart vertically by more than the thickness of the palm. When the length of the strap 25 needs to be adjusted slightly, the distance from the support means 10 to the support part 29a can be easily adjusted by changing and gripping the gripping parts 29a without having to go through the troublesome process of adjusting the length of the strap 25 using the length adjustment means 30.

In addition, in the present invention, as shown in FIG. 7, a number of click switches 13c are provided on the upper surface of the support means 10, and the click switches 13c are connected to the electronic circuit 13 and transmit signals to the display means 40 through a communication protocol to perform functions such as clicking a selection button 41b on the screen. In this case, the selection button 41b is often a predetermined button among a number of buttons.

The application program 41 of the display means 40 may further include a remote click function block 41a that automatically clicks a predetermined selection button 41b on the screen when a signal is received from the electronic circuit 13 that the strap 25 has been pulled with more than a set force.

Therefore, the user can easily select and operate the selection button 41b on the screen of the display means 40 through the click switch 13c or by pulling the strap 25 with more than a set force while exercising on the support means 10 without having to go to the display means 40, which is far away.

In addition, the present invention provides a number of event selection switches 13d on the upper surface of the support means 10, and the screen of the display means 40 is provided with an event matching unit 47 for inputting information in advance about which switch selects which event. Therefore, when the user presses the event selection switch 13d to exercise, the muscle strength data sensed by the first sensor 12 is automatically stored as the exercise result of the event even if the user exercises without looking at the display means 40. At this time, the event selection switch 13d can be used together with the click switch 13c, or can be provided separately. Of course, in order to use the click switch 13c and the event selection switch 13d together, a confirmation switch 13b is further provided, and when the confirmation switch 13b is pressed, it is used as the event selection switch 13d, and when it is not pressed, it is used as the click switch 13c, or vice versa.

In addition, although not shown in the drawings, the present invention provides a sensor inside the sensor bundle A on both sides that detects how much of the strap 25 has been unwound from the spool 32, and the length of the unwound straps 25 on both sides is displayed on the screen of the display means 40. By looking at this display, the user can easily align the lengths of the straps 25 on both sides, making it very easy to maintain balance during exercise.

In addition, in the present invention, as shown in Figures 8 and 9, a bench 50 is placed on the upper surface of the support means 10 in a perpendicular direction, and the bench (50) is placed with its legs (52) on the support means (10) side placed on the support means (10) so that the support means 10 is pressed and fixed by the user's weight. Therefore, the bench 50 simultaneously has the function of allowing the user to lie down and exercise, and the function of pressing and firmly fixing the support means 10 by the weight of the person lying down.

The second embodiment of the present invention, as shown in Figures 10 and 11, is provided with only one sensor bundle A consisting of a combination of a length adjustment means 30, a first sensor 12, a rotating support 15, etc., and an elastic band 28 is split into left and right sides at the end of the length adjustment part 27 and connected to both ends of a pair of handles 29 or a barbell bar, allowing exercise with both hands. Of course, when exercising with one hand, it is possible to exercise with one hand by connecting the elastic band 26 to only one side of the end of the length adjustment part 27. In this case, a screw shaft 17b and a nut 17c are provided at the lower end of the sensor bundle A, and it can be connected and installed to a separate scaffold or door frame for use.

Furthermore, as shown in FIG. 12, the third embodiment of the present invention can measure both muscle strength exercise data and aerobic exercise data using one device, resulting in a complementary synergistic effect. That is, since both muscle strength exercise and aerobic exercise can be measured through one main body and one electronic circuit 13, the unit price per function can be significantly reduced and the development and manufacturing processes can be greatly simplified. Also, since people who do aerobic exercise always feel the need for muscle strength exercise, and people who do strength exercise always feel the need for aerobic exercise, both can be done in parallel with one piece of equipment, time and space efficiency can be maximized. That is, a separate exercise space is not required, and a large synergistic effect can be achieved by appropriately mixing aerobic exercise and muscle strength exercise.

The above-mentioned objects, features and advantages of the present invention will become more apparent from the following detailed description, which is based on the accompanying drawings.

Figures 1 to 12 show various embodiments of the present invention. In the first embodiment of the present invention, as shown in Figure 1, a sensor bundle A connected to a strap 25 is provided on each side end of the support means 10, and a control box C connected to the sensors on both sides is provided in the center of the support means 10.

The strap 25 is a member that transmits the user's force to the first sensor 12 in FIG. 3, and as shown in FIG. 2, is divided into an elastic part 26 on one side that stretches elastically when the strap 25 is pulled, allowing the movement parts of the arms and legs to move, and a length adjustment part 27 that is connected to the elastic part 26 and allows the user to adjust the overall length of the strap 25 according to changes in posture, height, etc. The length adjustment part 27 does not stretch when the strap 25 is pulled, or stretches relatively less than the elastic part 26, allowing the user to freely adjust the length of the strap 25 according to changes in posture, height, etc.

On the other hand, the elastic part 26 is always fixed in length unless the user pulls it, and is made up of a number of elastic bands 28 with different diameters and thicknesses as shown in FIG. 1. For example, the yellow one is suitable for pulling with a force of 1 kg, the red one is suitable for 3 kg, the blue one is suitable for 5 kg, the purple one is suitable for 10 kg, and the black one is suitable for 20 kg, and so on. Therefore, for a person with muscle strength of 8.3 kg to exercise, the red and blue elastic bands 28 must be connected to the strap 25.

As shown in FIG. 1, such strap 25 has a ring 60 and a snap hook 61 that can be detachably attached to the ring 60 attached to the connection part between the elastic part 26 and the length adjustment part 27 and the handle 29. The handle 29 is attached to the upper end of the strap 25 so that it can be held by hand. As shown in FIG. 6, if multiple gripping parts 29a are provided spaced apart vertically and the distance between each gripping part 29a is formed to be greater than the thickness of the palm, the user can easily adjust the small distance from the support means 10 to the gripping parts 29a by changing and gripping the gripping parts 29a without having to adjust the length of the strap 25 separately.

The support means 10 is a platform-like member that the user can step on and lift, as shown in FIG. 1, and two sensor bundles A are provided on each side, each of which is a combination of a length adjustment means 30, a first sensor 12 shown in FIG. 3, and a rotating support pedestal 15. A control box C is provided in the center of the support means 10, incorporating electronic circuits 13 that are connected to the first sensors 12 on both sides.

The length adjustment means 30 is usually connected to the sensor bundle A at both ends of the support means 10 as shown in Figs. 3 to 5, and functions to connect the first sensor 12 and the strap 25 while adjusting the length of the strap 25. In the length adjustment means 30, a cylindrical spool 32 is rotatably installed inside a cover 31 of a certain size, and the length adjustment part 27 of the strap 25 is wound around the spool 32. At this time, the spool 32 is provided with a disk-shaped flange 33 at both ends, and a sawtooth stop groove 34 is provided at a certain interval on the circumferential surface of the flange 33, and the stop groove 34 controls the rotation of the spool 32 as the operating key 35 provided on one side of the cover 31 engages or disengages. At this time, the stop groove 34 can be formed not only on the circumferential surface of the flange 33, but also in the middle of the flange 33 or at any position on the spool 32, as long as it can engage with the operating key 35 to stop the spool 32 at a certain angular interval.

The operation key 35 is provided on one side of the cover 31 so as to be movable forward and backward or rotatable. First, as shown in Figs. 3 and 4, the forward and backward type has a fixed protrusion 36 protruding from one side of the operation key 35, which selectively engages with the stop groove 34 of the spool 32 to fix it, and is elastically supported by a spring 38a at the rear and has a push part 38 exposed to the outside of the cover 31 at the front. Therefore, the operation key 35 of this forward and backward type normally advances forward by the spring 38a, and the fixed protrusion 36 engages with the stop groove 34, so that the spool 32 cannot rotate and is fixed. In addition, if the push part 38 exposed to the outside is pressed as necessary, the operation key 35 is pushed backward, the fixed protrusion 36 is released from the stop groove 34, and the spool 32 rotates by the built-in spring-like elastic means (32a), and the length adjustment part 27 of the strap 25 is automatically wound around the spool 32 to adjust the length.

On the other hand, as shown in FIG. 5, the rotation type operation key 35 has a central part hinged to the cover 35a, a fixed protrusion 36 that is connected to the stop groove 34 at one end and a key driving means 39 such as a solenoid or a motor is connected to the other end. The key driving means 39 is controlled in conjunction with a key switch 39a that is exposed on the upper surface of the support means 10. Therefore, in this rotation type, when the key switch 39a is not pressed, the fixed protrusion 36 of the operation key 35 is connected to the stop groove 34, and the spool 32 cannot rotate and remains fixed. When the user presses the key switch 39c, the key driving means 39 is controlled in operation so that the fixed protrusion 36 is released from the stop groove 34, and the spool 32 rotates due to the built-in elastic means (32a), and the length adjustment part 27 of the strap 25 is automatically wound around the spool 32 to adjust the length. When the key switch 39a is released, the key drive means 39 extends again, and the fixed protrusion 36 of the operating key 35 engages with the stop groove 34, fixing the spool 32.

Furthermore, a pair of sensor bundles A are provided at both ends of the support means 10, and at the center of the sensor bundle A, as shown in Fig. 3, a vertical second shaft 17 is provided rotatably on the support means 10 through a bearing, and a horizontal turntable 18 is provided at the upper end of the second shaft 17. Vertically rotatable brackets 14 are provided in a line on the turntable 18, and a rotating support base 15 having an approximately U-shaped cross section is hinged to the upper end of the rotating bracket 14 through the first shaft 16 so as to be rotatable in the vertical direction, and the length adjustment means 30 is connected and installed inside the rotating support base 15. A sensor mounting portion 37 is provided inside the length adjustment means 30, and the first sensor 12 is installed by being assembled therein, and the first sensor 12 is connected and installed to the rotating support base 15 through a fastening means 24 in the form of a bolt. Therefore, no matter from which direction the user pulls the strap 25, the first sensor 12 is positioned perpendicular to the pulling force while freely rotating horizontally and vertically through the first axis 16 and the second axis 17, allowing it to accurately detect the force.

In addition, the first shaft 16 and the second shaft 17 are provided with hollow first and second shaft holes 19 and 20, and the signal line 21 of the first sensor 12 is wired to the outside through the first and second shaft holes 19 and 20, so that there is no risk of the signal line 21 being twisted or broken no matter how the length adjustment means 30 is rotated in the horizontal/vertical direction.

The first sensor 12 is connected to the strap 25 and detects the pulling force of the strap 25. Any type of sensor can be used, such as a load cell or a pressure sensor, as long as it can detect the force. The first sensor 12 is connected directly to one end of the strap 25 and can detect the pulling force of the strap 25, but it can also be connected to the strap 25 through a length adjustment means 30 as shown in FIG. 4, and of course it can be connected to the strap 25 through other types of members, such as a bar, as long as it can transmit the force.

The display means 40, as shown in FIG. 1 or FIG. 7, is for displaying the detected muscle strength, and can display muscle strength not only through an external digital device such as a smartphone, computer, or television, but also through the device's own display window 13a such as an LCD, LED, or FND provided on the device's control box C, all of which are included in the display means 40.

At this time, the screen of the display means 40 is provided with a balance checking section 44 that can check the balance of forces by comparing the user's left and right muscle strength as shown in FIG. 1, and is configured to allow the user to perform muscle exercises while checking their own left-right balance state in real time during exercise.

The screen of the display means 40 is provided with an exercise result display section 43 that displays the degree of muscle strength increase or decrease for each part of the human body on a human body structure diagram after the exercise is completed, as shown in FIG. 6, so that the user can easily understand at a glance how much muscle strength has increased in each part. In addition, the screen of the display means 40 is further provided with an exercise type recommendation section 45 that recommends focusing on parts with a low muscle strength increase rate or parts that need exercise based on the exercise results, so that even non-experts can perform systematic exercise.

As shown in FIG. 7, a number of switches are provided on the upper surface of the support means 10, and these switches consist of a power switch, a confirmation switch 13b, and a number of function switches. The function switches serve as the click switch 13c described below and the event selection switch 13d described below. In addition, the number of function switches can be used as both the click switch 13c and the event selection switch 13d. In this case, if the confirmation switch 13b is pressed and held down before pressing the function switch, the function switch will serve as the event selection switch 13d, and if the function switch is pressed immediately without pressing the confirmation switch 13b, the function switch will serve as the click switch 13c. Of course, the roles can be determined in the opposite way. It is of course possible to provide the click switch 13c and the event selection switch 13d separately.

The click switch 13c is connected to the electronic circuit 13, and the electronic circuit 13 transmits a signal to the display means 40 to make the selection button 41b on the screen clickable. That is, even if the user stands on the support means 10 and exercises, the user can perform operations such as clicking the selection button 41b on the screen of the display means 40, which is located a predetermined distance away, through the click switch 13c.

The application program 41 of the display means 40 is also provided with a remote click function block 41a that automatically clicks a specified selection button 41b on the screen when a signal is received from the electronic circuit 13 that the strap 25 has been pulled with more than a set force, and the selection button 41b on the screen of the display means 40 can be easily clicked and operated by pulling the strap 25 with more than a set force.

The event selection switch 13d is connected to the internal electronic circuit 13, and the electronic circuit 13 transmits a signal to the display means 40. The screen of the display means 40 is provided with an event matching section 47 that allows the user to select which exercise each event selection switch 13d is matched with. For example, when the user presses the No. 1 switch and clicks on one of the exercise events displayed on the screen, the No. 1 switch and the corresponding event are matched with each other. When the user presses the event selection switch 13d in this matched state to exercise the corresponding event, the muscle strength data sensed by the first sensor 12 is automatically stored in the storage means 48 such as the memory of the display means 40 even if the user exercises without looking at the display means 40, and the data is managed so that it can be confirmed through the exercise result display section 49 on the screen of the display means 40 as necessary.

The support means 10 of the present invention may be a scaffold-like support means 10 that the user steps on and is fixed in place as shown in Figures 1 to 7, but as shown in Figures 11(a) and (b), any type of member that is connected to a horizontal panel, vertical post, door frame D, etc. and can be firmly fixed in place, such as a bolt or C-channel, can all serve as the support means 10.

FIGS. 8 and 9 show a case where a separate bench 50 is connected to the support means 10 and the person performs muscle exercises while lying on the bench 50. The bench 50 is a panel of a certain size, and is installed with one leg 52 suspended on the support means 10 so as to be arranged perpendicular to the support means 10. At this time, a groove 10c is provided on the upper surface of the support means 10, and a protrusion 55 corresponding to the groove 10c is provided on one leg 52 of the bench 50, which are detachably fitted to each other.

The bench 50 is for a user to lie down and perform chest exercises or lower body exercises, and has a structure in which the support means 10 is pushed and firmly fixed by the weight of the person lying down. The bench 50 comprises a top plate 51 on which the user can lie down, and four pairs of legs 52 at both ends of the bottom surface of the top plate 51. The paired legs 52 on both sides are interconnected by a horizontal bar 53. The legs 52 can be used by maintaining them in an upright position by a bolt or pin-like fixing means 54, or can be stored folded under the bottom surface of the top plate 51. When the bench 50 is turned upside down for storage and the exercise device is stored on the bottom surface side of the top plate 51, the paired legs 52 can be folded, and the support means 10 of the exercise device is pushed and fixed by the horizontal bar 53 connecting the paired legs 52, so that the bench 50 and the exercise device can be stored together, which is convenient and reduces the volume and distribution costs.

On the other hand, the second embodiment of the present invention, as shown in Figs. 10(a) and (b) and Figs. 11(a) and (b), has only one sensor bundle A consisting of a combination of a length adjustment means 30, a first sensor 12, a rotating support 15, etc., and an elastic band 28 is split into left and right sides at the end of the length adjustment part 27 and connected to both ends of a pair of handles 29 or a barbell bar, so that it can be exercised with both hands. Of course, when exercising with one hand, it is possible to exercise with one hand by connecting the elastic band 26 to only one side of the end of the length adjustment part 27. In this case, a screw shaft 17b and a nut 17c are provided at the lower end of the sensor bundle A, and it can be connected and installed to a separate scaffold, a door D, a vertical post, etc., and in this case, the screw shaft 17b and the nut 17c play the role of the support means of the first embodiment for fixing and installing the equipment to a structure.

In addition, in the second embodiment, an electronic circuit 13 that processes the detected muscle force data and transmits it to the display means is disposed inside the sensor bundle A and is connected to the first sensor 12.

The third embodiment of the present invention is the same as the first embodiment in that it detects the force pulling the strap 25 as shown in FIG. 12, but further includes a push plate 22 on the upper side of the support means 10, and a second sensor 23 for detecting the force of stepping on or pushing the push plate 22 is further provided between the push plate 22 and the support means 10. Therefore, this second embodiment can detect aerobic exercise data such as a user climbing up on the push plate 22 or running on the push plate 22 through the second sensor 23 and display it externally through the display means 40. Also, the first sensor 12 can measure the force pulling the strap 25 but cannot measure the force of the user pushing with their hands or feet, but the second sensor 23 can additionally detect and display such pushing force, so more types of exercise can be performed.

The present invention described above is not limited to the above-mentioned embodiments and the accompanying drawings, and it will be apparent to those with ordinary skill in the art to which the present invention pertains that various substitutions, modifications and alterations are possible without departing from the technical concept of the present invention.
