Training device and barbell

A training device for strength training is capable of performing through use of a barbell, the training device including: a frame body; a support body configured to support the barbell from below; moving means for moving the support body to ascend and descend along the frame body; control means for controlling the moving means; and state detecting means for detecting a state of the barbell or a user, wherein the control means is configured to control the moving means based on a detection signal detected by the state detecting means. With the training device, various kinds of free-weight training can be solely and safely performed.

TECHNICAL FIELD

The present invention relates to a training device, and more specifically, to a training device with which free-weight training can be solely and safely performed and a barbell to be used together with the training device.

BACKGROUND ART

Methods of strength training utilizing equipment (excluding so-called “bodyweight training”) can be roughly divided into two types. One type is machine training using a dedicated device equipped with a weighted object, and the other type is free-weight training using, for example, a dumbbell or a barbell (hereinafter referred to as “weighted object”).

In the free-weight training, a person who performs the training (hereinafter referred to as “user”) is required to use his or her whole body to support a weight while keeping a balance. Thus, the free-weight training is said to have a higher training effect as compared to the machine training in which the weight passes a constant path and the balance is mechanically maintained.

The user can perform the free-weight training alone, but with assistance by a spotter, there are advantages in that more effective training is allowed (for example, pushing muscles to exhaustion and preventing injury), and more efficient training is allowed (showing effects in a shorter period of time).

In recent years, there has been proposed a training device configured so that training can be performed in an environment similar to the free-weight training with a spotter (Patent Literature 1).

DESCRIPTION OF EMBODIMENTS

First Embodiment

An example of a training device and a barbell according to the present invention is described with reference to the drawings. The training device according to the present invention is a device for strength training to be performed through use of a weighted object. In the following, as an example, description is given of a case in which the weighted object is a barbell W in which plates (weights) W2are provided on both ends in a longitudinal direction of a shaft W1.

As an example, the training device illustrated inFIG.1(a)includes a frame body10, a support body20, moving means30, state detecting means40, and control means50. The support body20is configured to support the barbell W. The moving means30is configured to move the support body20to ascend and descend along the frame body10. The state detecting means40is configured to detect a state of the barbell W or a user. The control means50is configured to control the moving means30.

The frame body10is a part serving as a framework of the training device. The frame body10in this embodiment includes two frame body bases11aand11band four support columns12(first support column12ato fourth support column12d). The two frame body bases11aand11bare arranged in parallel to each other at an interval on left and right sides, respectively. The four support columns12are provided upright at an interval in a front-and-rear direction of each of the frame body bases11aand11b. Both the frame body bases11aand11bhave one end sides coupled to each other by a first base coupling member11c, and other end sides coupled to each other by a second base coupling member11d. A step plate11eis provided on the first base coupling member11c.

Among the four support columns12, the first support column12aand the second support column12bare coupled to each other by a first coupling member13a, and the third support column12cand the fourth support column12dare coupled to each other by a second coupling member13b. Between the first coupling member13aand the second coupling member13b, a third coupling member13cis bridged on one end side, a fourth coupling member13dis bridged on another end side, and a pull-up/chin-up bar14is bridged at a middle position. On an inner side of the four support columns12ato12d, a training space S1in which a user performs training is formed.

An auxiliary support body15is provided on inner surface sides of the four support columns12ato12d. The auxiliary support body15in this embodiment includes locking plates15afixed to the support columns12, respectively, and a safety bar15bremovably mounted to the locking plates15a.

The locking plates15ain this embodiment are each a vertically-long plate-shaped member arranged along the support column12, and each have, on its surface, a plurality of locking holes15c, to which the safety bar15bis lockable, and which are formed at intervals in a height direction.

The safety bar15bin this embodiment is a bar-shaped member having locking protrusions (not shown) provided on its back surface. The safety bar15bis arranged in parallel to the first coupling member13aand the second coupling member13b. The safety bar15bcan be mounted to the locking plates15awhen the locking protrusions are locked to any locking holes15csuitable for the training type. The auxiliary support body15may be provided as required, and can be omitted when not required.

The configuration of the frame body10is merely an example, and other configurations can also be adopted.

The support body20is configured to support the barbell W from below. In this embodiment, one support body20is provided between the first support column12aand the second support column12b, and another support body20is provided between the third support column12cand the fourth support column12d(two support bodies20in total). The two support bodies20are provided at opposed positions at the same height. The barbell W is horizontally supported on both end sides in the longitudinal direction thereof by those two support bodies20.

As an example, the support body20illustrated inFIG.2(a)toFIG.2(c)includes a support body base21, dampers22, and a receiving portion23. The dampers22are provided at intervals in a width direction of the support body base21. The receiving portion23is provided above the dampers22.

The support body base21has a horizontally-long box shape, and both ends in the width direction thereof are held by sliders32to be described later. The support body base21has shock absorbers provided thereon as the dampers22configured to reduce the impact applied to the receiving portion23. In this embodiment, as an example, there is shown a case in which five shock absorbers are provided, but the number of shock absorbers may be larger or smaller than five.

As illustrated inFIG.2(c), guides24are provided on outer sides of, among the five shock absorbers, shock absorbers arranged on both outer sides. The guides24each include a bush24aand a shaft24baccommodated in the bush24a. The guides24are configured to guide the receiving portion23so that the receiving portion23is vertically movable without shifting in a horizontal direction. The bushes24aare provided on the support body base21, and the shafts24bare provided on the receiving portion23.

The receiving portion23is provided above the five shock absorbers. The receiving portion23is a part configured to support the barbell W from below. The receiving portion23has a support surface for supporting the weighted object. The receiving portion23in this embodiment is formed into a V-shape having downward inclinations from both end sides in a longitudinal direction toward a middle portion. The barbell W is supported under a state in which the barbell W is movable on the support surface.

Both inclined surfaces of the receiving portion23(front downward-inclined surface23aand rear downward-inclined surface23b) function as a guiding portion (front-and-rear direction guiding portion) configured to guide the barbell W to a middle portion (lowest portion) in the front-and-rear direction (FIG.3(a)toFIG.3(c)). The receiving portion23can be formed so that the lowest portion is located at a position shifted to the front or rear side from the middle portion. The receiving portion23may have a horizontal upper surface.

The receiving portion23in this embodiment has, in addition to the front downward-inclined surface23aand the rear downward-inclined surface23b, an outer downward-inclined surface23cinclined outward. The outer downward-inclined surface23cfunctions as a guiding portion (lateral direction guiding portion) configured to guide the barbell W to a middle portion in a right-and-left direction.

Specifically, when a barbell70(seeFIG.11(a)toFIG.11(c)) to be described later is used, a conical portion72aof a flange72is brought into abutment against the outer downward-inclined surface23cso that the barbell70is guided to the middle portion in the right-and-left direction (FIG.4(a)toFIG.4(c)).

Sensor brackets25are provided one by one on both end sides in the longitudinal direction of the receiving portion23, and proximity detecting means26is provided on each of the sensor brackets25. The proximity detecting means26is means for detecting that the weighted object is brought closer to the support body beyond a reference separation distance.

As the proximity detecting means26, for example, various laser sensors can be used, but sensors other than the laser sensors can also be used.

In this embodiment, contact detecting means27(FIG.5) for detecting that the barbell W is brought into contact with the support body20(receiving portion23) is provided on the receiving portion23. In this embodiment, a load sensor is used as the contact detecting means27.

As the contact detecting means27, means other than the load sensor can also be used as long as the means can detect the contact to the support body20(receiving portion23). For example, a physical switch configured to turn on in response to contact of the barbell W, or an eddy current sensor configured to measure a distance with respect to the barbell W through use of a high frequency magnetic field can be used. The contact detecting means27may be provided as required, and can be omitted when not required.

The configuration of the support body20is merely an example, and other configurations can also be adopted.

The moving means30is configured to move the support body20to ascend and descend along the support columns12of the frame body10. In this embodiment, a linear actuator is used as the moving means30. The linear actuator includes a guide rail31, and the slider32configured to slide along the guide rail31.

In this embodiment, one guide rail31is provided on a front surface side of the first support column12a, one guide rail31is provided on a rear surface side of the second support column12b, one guide rail31is provided on a front surface side of the third support column12c, and one guide rail31is provided on a rear surface side of the fourth support column (four guide rails31in total).

A first slider32ais provided on the guide rail (first guide rail31a) on the front surface side of the first support column12a, a second slider32bis provided on the guide rail (second guide rail31b) on the rear surface side of the second support column12b, a third slider32cis provided on the guide rail (third guide rail31c) on the front surface side of the third support column12c, and a fourth slider32dis provided on the guide rail (fourth guide rail31d) on the rear surface side of the fourth support column12d.

One of the two support bodies20is bridged between the first slider32aand the second slider32b, and the other thereof is bridged between the third slider32cand the fourth slider32d. Both the support bodies20are each held at both ends in the longitudinal direction by the sliders32.

In this embodiment, all of the first slider32a, the second slider32b, the third slider32c, and the fourth slider32dare caused to ascend and descend in synchronization with each other so that both the support bodies20ascend and descend at the same height while keeping horizontal postures. One linear actuator may be provided for one support body20(one linear actuator in total). In this case, only one end side in the longitudinal direction of each support body20is held by the slider32with an actuator, and the other end side thereof is held by the slider32without an actuator.

The linear actuator in this embodiment is controlled by the control means50. The control of the linear actuator is to be described later. As long as the means can move the support body20to ascend and descend, means other than a linear actuator can be used as the moving means30.

The state detecting means40is means for detecting a state of the barbell W or the user. In this embodiment, a depth camera (depth sensor) is used as the state detecting means40. The depth camera in this embodiment is configured to detect position information of the shaft W1of the barbell W. The depth camera in this embodiment can measure a distance from the depth camera to the barbell W (shaft W1).

As illustrated inFIG.1(a)andFIG.1(b), in this embodiment, the depth camera is provided on an upper part of the second support column12bso that a lower end portion of the depth camera is positioned on the upper side by about 40 cm from an upper surface of the support body20at the highest position. The depth camera can be provided at other positions. An installation position and an installation angle of the depth camera can be adjusted as appropriate so that a desired angle of view can be obtained. In this embodiment, as an example, there is shown a case in which one depth camera is used, but two or more depth cameras can also be provided.

Although not shown, information acquired by the depth camera is transmitted to a processing unit connected to the depth camera, and is processed by the processing unit. In this embodiment, in the processing unit, a moving speed, a path, and a lateral balance of the barbell W can be calculated based on a change over time of the position information acquired by the depth camera.

Specifically, an angle of the barbell W can be calculated based on the number of pixels, and the position of the shaft W1can be identified from the calculated angle and the distance to the shaft W1measured by the depth camera.

In this embodiment, the information acquired by the depth camera and the information calculated by the processing unit are transmitted to the control means50, and the moving means30is controlled based on the transmitted pieces of information.

As the state detecting means40, other than the depth camera, an optical camera configured to shoot, for example, a motion of the barbell or a motion of the user, and a sound sensor configured to detect, for example, voice output from the user can also be used.

When the optical camera is used as the state detecting means40, a position, a moving speed, a path, a lateral balance, or the like of the barbell W can be calculated through machine learning from image data (moving image) obtained by the optical camera. Also in this case, the information acquired by the optical camera and the information calculated by the processing unit can be transmitted to the control means50, and the moving means30can be controlled based on those transmitted pieces of information.

When the sound sensor is used as the state detecting means40, it can be determined that the user has reached the limit when the sound sensor detects voice of the user, and the moving means30can be controlled in response thereto.

The state detecting means40can be provided on the barbell W. For example, the barbell may be equipped with a gyroscope sensor, and the gyroscope sensor may measure an acceleration of the barbell W. The gyroscope sensor can be provided on the interior or the exterior of the barbell W. Other than the gyroscope sensor, a switch to be operated by the user may be provided on the barbell W so that the state of the user can be detected through an operation of the switch.

The configuration of the state detecting means40is merely an example, and other configurations can also be adopted.

The control means50is configured to control the moving means30and other various pieces of equipment. As illustrated inFIG.5, in this embodiment, the moving means30is controlled based on a signal transmitted from the proximity detecting means26, a signal transmitted from the contact detecting means27, and a signal transmitted from the state detecting means40.

Now, description is given of control that is based on the signal transmitted from the proximity detecting means26, control that is based on the signal transmitted from the contact detecting means27, and control that is based on the signal transmitted from the state detecting means40. The following types of control are merely examples, and other types of control can also be performed.

First, description is given of the control that is based on the signal transmitted from the proximity detecting means26and the control that is based on the signal transmitted from the contact detecting means27. As illustrated inFIG.6(a)toFIG.6(d), when the proximity detecting means26detects that the barbell W is brought closer to the support body20beyond the reference separation distance at the time when the support body20ascends, the moving means30is controlled so that the support body20is decelerated. With this control, the impact of the barbell W to be applied to the support body20is reduced.

After the support body20is decelerated by the control, when the contact detecting means27detects that the barbell W is brought into contact with the support body20, the moving means30is controlled so that the support body20is accelerated. With this control, the barbell W is caused to rapidly ascend, thereby being capable of preventing the user from being crushed by the barbell W.

In a simulation performed by the applicant, when the support body20was brought into contact with the barbell W (stationary state) of 120 kg held by the user at a moving speed of 270 mm/s, an impact force was 893 kgf, but when the moving speed of the support body20was decreased to 50 mm/s, the impact force was 31 kgf. From the simulation results, a great damping effect due to the deceleration of the support body20was recognized.

In the control, the moving means30can be controlled as follows. Instead of supporting the entire (100%) load to be applied to the support body20, a difference between a weight of the barbell W set in advance and a weight detected by the contact detecting means (load sensor)27may be calculated, and assistance may be given by an amount corresponding to the difference.

For example, in a case in which the weight of the barbell W set in advance is 100 kg, when the weight detected by the load sensor is 30 kg, it can be determined that the user still has strength to lift up a weight of 70 kg, and the control can be performed to give assistance by an amount corresponding to the lacking weight of 30 kg.

Next, description is given of the control that is based on the signal transmitted from the state detecting means40. In this embodiment, the moving means30is controlled in accordance with each of three modes of a “normal mode (Normal MODE),” a “forced-reps mode (Forced-Reps MODE),” and a “drop-sets mode (Drop-Sets MODE).”

The “normal mode (Normal MODE)” is a mode in a case in which training similar to general free-weight training to be performed without a spotter is performed. The “forced-reps mode (Forced-Reps MODE)” is a mode in a case in which training similar to forced-reps training is performed. The “drop-sets mode (Drop-Sets MODE)” is a mode in a case in which training similar to drop-sets training is performed.

In this case, the forced-reps training refers to a training method in which the spotter supports the lifting of the barbell W when the user cannot lift up the barbell W anymore, thereby being capable of increasing the number of lift-up times of the barbell W as compared to a case in which the user performs the training alone.

Further, the drop-sets training refers to a training method in which the spotter reduces the weight of the barbell little by little at the timing at which the user comes close to the limit and cannot lift up the barbell W any more, thereby being capable of increasing the number of lift-up times of the barbell W as compared to the case in which the user performs the training alone. Both of the methods are said to be one of most efficient training methods with which results can be achieved in a short period of time.

Now, description is given of the control in each of the training modes of the “normal mode (Normal MODE),” the “forced-reps mode (Forced-Reps MODE),” and the “drop-sets mode (Drop-Sets MODE).”

As illustrated inFIG.7, in the “normal mode (Normal MODE),” when the state detecting means40detects that the barbell W lowered to the bottom is not lifted up for a certain time period or more (Limit Detect), that the user has given an instruction of intervention by voice or a barbell operation (User Action), or that the number of repetitions set in advance has been finished (Final Rep), the moving means30is controlled so that the support body20ascends (Slider Up).

The state detecting means40may detect, in addition to the above, intervention instructions of the user given by methods other than the voice or the barbell operation (for example, a switch to be stepped by a foot) or a body state of the user (for example, an abnormality in heart rate), and the moving means30may be controlled based on the detection results.

Further, when the state detecting means40detects a state in which there is a high probability of injury or accident, the moving means30may be controlled so that the support body20ascends. Specifically, the state detecting means40, for example, the optical camera can measure a training form in real time, and when a state in which a form collapse leading to injury or an actual unbalance causing falling becomes apparent (for example, when the form of the user falls outside of a range of a reference form set in advance), the control can be performed so that the support body20automatically ascends to hold the barbell W. Similarly, when the state detecting means40, for example, a vital sensor detects that vitals such as heartbeat and breathing have abnormal values (for example, the vital data of the user falls outside of a range of reference vitals set in advance), the control can be performed so that the support body20automatically ascends to hold the barbell W.

After that, when the barbell W ascends to reach a start position by the support body20, the moving means30is controlled so that the support body20is stopped at this position (Start Position).

When the support body20ascends, sound output means28(FIG.5) can output an alert.

As illustrated inFIG.8, in the “forced-reps mode (Forced-Reps MODE),” when the state detecting means40detects that the barbell W lowered to the bottom is not lifted up for a certain time period or more, or that the user has given an instruction of intervention by voice or a barbell operation, the moving means30is controlled so that the support body20ascends to reach a position at which the support body20can support the barbell W.

When the barbell W is supported by the ascending support body20, the moving means30is controlled so that the support body20ascends in consideration of the remaining muscular strength of the user (Power Assist).

After that, when the barbell W ascends to reach the start position by the support body20, the support by the support body20is canceled.

In this mode, the control is performed until the number of repetitions set in advance is finished. Meanwhile, when the state detecting means40detects that a descending speed of the barbell W is faster than a speed set in advance (Descend Speed), the moving means30is controlled so that the support body20ascends to reach a position at which the support body20can support the barbell W. When the barbell W is supported by the support body20, the moving means30is automatically stopped.

Similarly to the case of the “normal mode (Normal MODE),” also in this mode, when the support body20ascends, the sound output means28(FIG.5) can output an alert.

As illustrated inFIG.9, in the “drop-sets mode (Drop-Sets MODE),” when the state detecting means40detects that the barbell W lowered to the bottom is not lifted up for a certain time period or more, that the user has given an instruction of intervention by voice or a barbell operation, that a speed to lift up the barbell is slower than a speed set in advance (Ascend Speed), or that the barbell is held at a top position (position obtained when the user extends his or her arms) for a certain time period set in advance or more (Position Hold), the moving means30is controlled so that the support body20ascends to reach a position at which the support body20can support the barbell W.

When the barbell W is supported by the ascending support body20, a weight of the weight W2is automatically changed at a predetermined position (for example, a position of a predetermined support bar63of a plate rack60to be described later) (Plate Change). After that, the user restarts raising and lowering the barbell W without an interval.

As described above, the weight W2can be automatically changed, and hence the user is not required to replace the weight W2by himself or herself. Thus, the user can immediately start the next set without an interval (rest), thereby being capable of efficiently performing the drop-sets training. The function of automatically changing the weight W2is not always required, and can be omitted when not required. When the function of automatically changing the weight W2is not used, for example, the plate rack60illustrated inFIG.10(a)toFIG.10(c)can be used.

Next, description is given of the replacement of the weight W2. The plate racks60illustrated inFIG.10(a)toFIG.10(c)are used while being arranged on both outer sides in a width direction of the frame body10. Each of the plate racks60includes a scaffold plate61, a rack support column62provided upright from the scaffold plate61, and support bars63provided to laterally protrude from the rack support column62.

In this embodiment, three support bars63are provided to protrude at intervals in a height direction of the rack support column62. The support bars63of the right and left plate racks60are provided so that lower support bars, middle support bars, and upper support bars thereof have the same heights.

Each support bar63holds the weight W2. In this embodiment, the weight W2held by the middle support bar63bis lighter than the weight W2held by the lower support bar63a, and the weight W2held by the upper support bar63cis lighter than the weight W2held by the middle support bar63b.

When the user replaces the weight W2, the weight W2mounted on the shaft W1is slid and moved to the support bar63present at the same height as the shaft W1(weight W2in use is removed).

After that, the support body20is moved so that the shaft W1is brought to the same height as a different support bar63, and the weight W2held by the support bar63is slid and moved to the shaft W1(different weight W2is mounted), thereby being capable of easily replacing the weight W2.

When the training device according to the present invention is used, an existing barbell W can be used, but a dedicated barbell70developed for the training device according to the present invention can also be used.

As an example, the barbell70illustrated inFIG.11(a)toFIG.11(c)is developed for the training device according to the present invention, and includes a shaft71, flanges72, and weight equipping portions73. The shaft71is to be gripped by the user. The flanges72are provided at positions closer to the outer sides in the longitudinal direction of the shaft71. The weight equipping portions73are provided on the outer sides of both the flanges72. The weight W2is to be mounted to each of the weight equipping portions73.

As illustrated inFIG.11(c), the shaft71has a pipe shape, and round bar-shaped core members74are inserted to both end portions in the longitudinal direction of the shaft71(the shaft71and/or the core members74is referred to as “a long bar” in this application). The flanges72are rotatably mounted through intermediation of first bearings75at positions closer to the shaft71of both the core members74. As the shaft71, a core member (member that is not hollow) may be used in place of a pipe.

Both the flanges72each have a shape including a cylindrical portion72bon a distal end side of the conical portion72a. In parts of both the core members74on the outer sides of both the flanges72, the cylindrical weight equipping portions73are rotatably provided through intermediation of second bearings76. Both the weight equipping portions73are held by lock nuts77so that the weight equipping portions73are prevented from falling off from the core members74.

In the barbell W, the shaft71, the flanges72, and the weight equipping portions73are each rotatably coupled through intermediation of bearings. Accordingly, when the conical portion of the weight equipping portion73is placed on the receiving portion23of the support body20, the barbell W is smoothly guided to the middle portion (lowest portion) even when the barbell W is equipped with a weight.

Further, as described above, the conical portion72aof the flange72in the barbell W abuts against the outer downward-inclined surface23cof the receiving portion23in the support body20. In this manner, the barbell W is guided to the middle portion in the right-and-left direction.

The barbell70illustrated inFIG.11(a)toFIG.11(c)is merely an example, and, as the barbell W, an existing barbell and barbells having structures other than that of the barbell70illustrated inFIG.11(a)toFIG.11(c)can also be used.

Second Embodiment

Another example of the training device according to the present invention is described with reference to the drawings. The basic configuration of the training device according to this embodiment is similar to that in the case of the first embodiment. Differences reside in that, as illustrated inFIG.12, a physical measurement space S2is provided on the front side of a training space S1, and that physical data acquiring means80for acquiring physical data of the user is provided in the physical measurement space S2. In the following, matters different from those in the first embodiment are mainly described, and description of matters similar to those in the first embodiment is omitted as appropriate.

The frame body10in this embodiment includes an additional first support column12eprovided upright on the front side of the second support column12b, and an additional second support column12fprovided upright on the front side of the fourth support column12d. The additional first support column12eis provided upright on the frame body base11aextended to the front side of the second support column12b, and the additional second support column12fis provided upright on the frame body base11bextended to the front side of the fourth support column12d.

Extended front end portions of both the frame body bases11aand11bare coupled to each other by an additional coupling member11f. Upper end portions of the additional first support column12eand the additional second support column12fare coupled to each other by a fifth coupling member13e.

As illustrated inFIG.12, in this embodiment, the physical measurement space S2is formed on the inner side of the second support column12b, the fourth support column12d, the additional first support column12e, and the additional second support column12f, and the physical data acquiring means80is provided in the physical measurement space S2. As the physical data acquiring means80, for example, an existing 3D scanner can be used.

In this embodiment, with the physical data acquiring means80, various kinds of physical data can be measured, such as, in addition to the height and the length of arms and legs of the user, sizes around the neck, around the upper arm, around the chest, around the waist, around the hips, around the thigh, and around the calf.

Before the training is started, the physical data acquiring means80can measure the physical data, and various settings of the support body20(for example, a top position (initial position) and a bottom position (maximum position to lower the barbell)) can be automatically adjusted based on the measured data. At this time, it is preferred that the locking plate15aof the auxiliary support body15be fixed in the vicinity of the bottom position, and thus, for example, a display monitor81to be described later can be used to notify the user of the bottom position. Further, the physical data acquiring means80can measure the physical data before and after the training so that the contents of the training can be determined based on the data.

In this embodiment, the display monitor81is provided between the additional first support column12eand the additional second support column12f. As the display monitor81, a mirror display having both functions of a mirror and a display, a digital signage, or the like can be used.

On the display monitor81, various kinds of information can be displayed, such as a status of the user, training information, information related to injury, a more effective training method, and advertisements of training equipment and protein drinks.

The display monitor81may be provided as required, and can be omitted when not required. Further, a mirror without a display function can be provided between the additional first support column12eand the additional second support column12fin place of the display monitor81.

Other Embodiment

Although description is omitted in the first and second embodiments, a lifting platform can be provided on a floor surface of the training space S1. As the lifting platform, an existing or new lifting platform, for example, a pantograph lifting platform can be used.

With the lifting platform being provided, training at a low position, for example, hip thrusts and squats, can be supported. The lifting platform may be provided as required, and can be omitted when not required.

Although description is omitted in the first and second embodiments, a measurement mat including a pressure sensor (pressure distribution sensor) can also be provided on the floor surface of the training space S1. With such a measurement mat being provided, the balance of loads applied to the feet at the time of training can be checked.

Although description is omitted in the first and second embodiments, placement stages (not shown) can be provided to both the support bodies20so that the user gripping the pull-up/chin-up bar14can place his or her legs thereon when performing the pull-up/chin-up training. The placement stages can be removed when the pull-up/chin-up training is not performed.

Through use of the placement stages, pull-up/chin-up training using the bodyweight called “chinning” can be effectively performed. It is difficult for a user having insufficient muscular strength to solely perform chinning in which the whole body weight is supported by grip and arm strength, and in general personal training, the chinning is performed under a state in which the spotter supports his or her legs, thereby being capable of increasing the training effect. However, in this embodiment, the placement stages can be used so that training similar thereto can be solely performed.

Specifically, the user can hang down from the pull-up/chin-up bar14and have his or her legs (knees) placed on the placement stages. The pull-up/chin-up can be performed under this state so that an effect similar to that in the case in which the chinning is performed with his or her legs being supported by the spotter can be obtained.

In the second embodiment, as an example, there is shown a case in which the training space S1and the physical measurement space S2are provided in one frame body10, but the training space S1and the physical measurement space S2can be provided in different frame bodies10. In this case, it is preferred that the physical measurement space S2be provided in the vicinity of the frame body10forming the training space S1.

INDUSTRIAL APPLICABILITY
