It is attached to the end of the handlebar 14 via a longitudinal central force screw 9 (support shaft) facing the grip portion 5a.

[0017] That is, a through hole 5c is formed in the longitudinal center of the front portion 5b, and a cylindrical liner 10 having a hat-shaped cross section is fitted into the through hole 5c so as not to rotate. You. The liner 10 is formed of a material having a low coefficient of friction, and a shaft 9b of the screw 9 (parallel to the shaft 7b of the screw 7) is rotatably fitted.

A screw hole 11 into which the tip of the shaft 9b of the screw 9 is screwed is provided at the tip of the handlebar 4. A small clearance is formed between the handlebar 4 and the front portion 5b of the handle 5, and between the liner 10 and the head 9a of the screw 9, and the handle 5 is provided around the shaft 9b of the screw 9. It can rotate smoothly.

A plurality of screw holes 11 are provided at both ends of the handlebar 4 at predetermined intervals in the length direction, and by changing the screw holes 11 into which the screws 9 are screwed, The position of handle 5 can be changed.

As shown in FIG. 1, arms 12 which are orthogonal to the bar 2 and extend in parallel with each other are fixed to both left and right ends of the bar 2. A through hole 12a is provided at the tip of each arm 12. An annular end portion 13a of the wire 13 is attached to the through hole 12a. The other ends 13b of the wires 13, 13 are connected to tips of a pair of ropes 15, 15 drawn out from the weight training machine 14 (load applying means).

The weight training machine 14 includes a pair of weight elevating units 16, 16 erected vertically at right and left intervals, and a pair of guide bars erected vertically on both left and right sides to sandwich them. 17 and a rope guide portion 18 fixed between the guide bars 17 and 17 so as to be able to move up and down.

As shown in FIG. 5, each weight lifting section 16 includes a pair of left and right guide bars 19, 19, which are vertically erected, a weight support section 20, which is attached to these vertically and vertically, and a weight support section 20. A plurality of plate-shaped weights 21, 21,... Which are arranged below the portion 20 and are vertically engaged with the guide bars 19, 19 and vertically stacked, and are mounted on the upper ends of the guide bars 19, 19. And a rope guide device 22 attached thereto.

On the floor of the training room, a rectangular plate 23 is fixed along the wall W, and guide bars 19, 19 are erected on the upper surface thereof.

Further, a rectangular plate 24 is fixed horizontally on the wall surface W of the training room so as to be positioned vertically above the plate 23, and the rope guide device 22 is fixed to the front surface thereof.

[0025] The weight support portion 20 engages with the guide bars 19, 19 so as to be able to move up and down, and has a pair of left and right bearing plates 25, 25 on its upper surface. It is rotatably supported. Further, a shaft 27 penetrating through each weight 21 projects vertically downward from the lower surface of the weight support portion 20.

The shaft 27 is provided with through holes 27a, 27a,... Penetrating back and forth at regular intervals in the axial direction, and the interval is equal to the thickness of one weight 21.

[0027] Each weight 21 is provided with a pin through hole 21a penetrating back and forth, and a shaft through hole 21b penetrating vertically and penetrating the shaft 27.

When the weight support portions 20 abut on the upper surface of the uppermost weight 21 in a state where the weights 21 are vertically overlapped, the through holes 27a of the shaft 27 Align with hole 21a. Insert pin 28 into pin through hole 21a of any weight 21 Then, the pin 28 penetrates through the weight 21 and the shaft 27, and the tip portion projects rearward of the shaft 27.

When the weight support 20 rises in this state, the weight 21 through which the pin 28 has been inserted and all the weights 21 located above the weight 21 rise together while being suspended by the weight support 20. Therefore, by changing the weight 21 through which the pin 28 is inserted, it is possible to adjust the number of the weights 21 suspended on the weight support portion 20.

[0030] The rope guide device 22 includes a bearing 29 fixed to the upper ends of the guide bars 19, 19 and the plate member 24, a bearing portion 30 rotatably supported by the housing 29 in a horizontal direction, and a A pulley 31 which is vertically and rotatably supported on a bearing part 30 is provided.

[0031] The guide bars 17, 17 have an upper end fixed to the plate 24 via the support member 32 and a lower end fixed to the plate 23.

The rope guide portion 18 includes a plate-like support member 34 fixed to the guide bars 17, 17 so as to be able to move up and down horizontally, and a pair of holders 35 attached to the left and right ends of the front surface of the support member 34. 35, a bearing portion 36 rotatably supported on each holder 35 in a horizontal direction, a pulley 37 vertically and rotatably supported on each bearing portion 36, and upper and lower ends of a support member 34. And a pulley 39 which is vertically and rotatably supported by each bearing portion 38.

[0033] At the front end of each bearing portion 36, a gate portion 40 is provided for guiding the rope 15 pulled out from the pulley 37 forward. A guide rod 41 is provided at the front end of each bearing portion 38 to form a gap between the pulley 39 and the pulley 39 so that the rope 15 can pass therethrough.

[0034] The rope 15 drawn into the gate portion 40 is wound around the outer peripheral portion of the pulley 37, penetrates through the through hole 35a at the top of the holder 135, engages with the outer peripheral portion of the pulley 39, and It is wound around the outer peripheral portion of the pulley 31 and extends downward, is wound around the outer peripheral portion of the pulley 26 and extends upward, and the upper end is attached to the lower surface of the housing 29.

When the rope 15 pulled out from the gate portion 40 is pulled forward, the weight support portions 20 and the weights 21 suspended therefrom rise, and when the force for pulling the rope 15 is reduced, the weight support portions 20 and Weight 21 falls.

Next, a method of using the training device 1 will be described with reference to FIG. training When the user grips the handles 5, 5 of the pressing operation unit 3 with both hands and presses forward, the pressing force is transmitted to the bar 2 via the support member 6, and further transmitted through the arms 12, 12, and the wires 13, 13. It is transmitted to the ropes 15, 15 (see Fig. 5).

[0037] As a result, a force in the ascending direction is applied to each weight supporting portion 20, and the weight supporting portion 20 and the weight 21 suspended therefrom are lifted, so that these weights act on the ropes 15, 15. The weight is transmitted to both ends of the bar 2 via the wires 13, 13 and the arms 12, 12, and applies a rearward load to the bar 2.

[0038] By repeating the operation in which the trainee pushes both the arms and presses the pressing operation unit 3 forward so as not to lose the load, the muscle strength of the upper arm and the trunk can be strengthened. Further, since the pressing operation unit 3 is rotatable 360 ° in both directions and is unstable, it is possible to train the wrist and to strengthen the muscular strength of the forearm.

In the present embodiment, the handles 5, 5 are rotatable 360 ° in both directions, and the wrist can be turned. The training can be performed with an action and image that is very similar to the push and pull actions performed in judo approaches. By wrapping a cloth made of the same material as the judo clothes around the grip 5a of the handle 5, training with an image more similar to the actual judo approach is possible.

[0040] Further, when pressing the pressing operation part 3, the gripping force and the muscle strength of the shoulder can be strengthened because the handlebars 5, 5 are gripped with force and both arms are pushed forward. In addition, when pressing the pressing operation unit 3, it is necessary to step on the foot to balance, so that not only the upper body but also the lower body can be strengthened. In particular, the upper arm, forearm, rectus abdominis, pectoralis major, latissimus dorsi, etc. can be obtained.

Further, in the present embodiment, since both ends of the bar 2 are pulled through the ropes 15, 15 to apply a load, the bar 2 is unstable, so that when the pressing operation unit 3 is operated, Bar 2 rocks in a vertical plane. Such a structure is particularly effective for strengthening the lower body.

[0042] By performing training with the training device 1, in the judo approach, a force can be applied that resists the opponent's attraction or push by pushing with his arm.

The size of the load that the weight training machine 14 applies to the bar 2 depends on the weight It can be adjusted by changing the number of weights 21 suspended on the part 20. The height of the ropes 15, 15 from the floor surface can be adjusted by raising and lowering the support member 34 of the rope guide portion 18.

Further, in the present embodiment, since the bearings 36, 36 for supporting the pulleys 37, 37 of the rope guide 18 are rotatable in the horizontal direction, when the trainee changes the direction in which both arms protrude. In addition, since the wires 13 and 13 do not come off or twist and do not generate unnecessary resistance, the degree of safety is high.

[0045] Furthermore, by measuring the weight of the weight 21, it is possible to know the magnitude of the load applied to the bar 2, and therefore, based on numerical evidence! Can be.

FIGS. 17 to 21 show modified examples of the first embodiment.

In the example shown in FIG. 17, the support member 6 can be rotated around the central axis of the bar 2 and fixed at an arbitrary position. When the pressing operation unit 3 is rotated and fixed at a position rotated by about 180 ° around the center axis of the bar 2 and a tensile force is applied to the bar 2 in the arrow direction through the pressing operation unit 3 at this position, A load contrary to this pulling force is applied to both ends of the bar 2 by the weight training machine 14 (see FIG. 1). In this way, training can be performed with an action similar to the action of grasping and attracting the opponent with both hands.

In the example shown in FIG. 18, a pressing operation unit 42 for one-handed operation can be rotatably attached via a screw 7 in place of the pressing operation unit 3. The pressing operation unit 42 is formed in the same manner as the handle 5 of the pressing operation unit 3, and is operated by the trainee with one hand. In this way, the training can be performed with an action similar to the action of grasping and pushing the opponent with one hand.

In the example shown in FIG. 19, a pair of handles 5 can be attached to handlebar 4 such that one has a step X in the axial direction of screw 7 with respect to the other. That is, the spacer 50 having a height corresponding to the step X can be inserted between the handle 5 and the handlebar 4. By doing so, training can be performed with one arm extended and the other arm contracted, so that training corresponding to various approaches can be performed. The example shown in FIG. 20 includes exercise amount display means 43 for calculating and displaying the exercise amount of the trainee. The exercise amount display means 43 includes a counter 44 that counts the number of the weights 21 that move up and down and the number of times of ascending and descending, a counting circuit 45 that calculates the amount of exercise based on the detection value of the counter 44, and an amount of exercise calculated by the And a display device 46 for displaying.

It should be noted that the counting circuit 45 and the display device 46 may be designed specifically, or only a new personal computer may be created using a general personal computer. The displayed amount of exercise is not particularly limited. For example, the number of times of ascending and descending, total weight, kinetic energy (calories), and the like can be displayed. In this way, rational training based on numerical evidence can be performed.

In the example shown in FIG. 21, a human figure mounting portion 48 for mounting a virtual opponent doll 47 to the bar 2 is provided. The doll attachment portion 48 is a rod-shaped member, one end of which is fixed to the outer peripheral surface of the support member 6 and protrudes in a direction perpendicular to the bar 2. The doll 47 is arranged facing the front of the trainee, and is fixed to the tip of the doll mounting portion 48 by the fixing member 49. By doing so, training can be conducted that imagined actual efforts.

Note that the examples shown in FIGS. 17 to 21 may be implemented alone, or may be implemented by appropriately combining some of them.

The magnitude of the load acting on one end of the bar 2 and the magnitude of the load acting on the other end of the bar 2 instantly become unbalanced according to the magnitude of the pressing force or the tensile force acting on the bar 2. It may be configured as follows. In this way, training that approximates the varied movements in actual judo approaches is possible.

[0055] As a mechanism having such an operation and effect, for example, a clutch mechanism is provided in one of the weight elevating and lowering parts 16, and when the speed of the wire 15 connected to the weight elevating and lowering part 16 exceeds a certain speed, a clutch is provided. It is conceivable that the mechanism operates to interrupt the transmission of the load to the wire 15.

Further, it is safe to provide a mechanism for preventing the weight 21 from dropping abruptly when the operation of pushing or pulling the bar 2 suddenly stops. Such a mechanism includes, for example, a pulley that guides the wire 15 and a flyweight that swings when the centrifugal force exceeds a predetermined value. It is conceivable to provide a brake shoe which grips and holds the wire 15 when the fly weight swings.

Next, a second embodiment of the present invention will be described. 7 is an overall perspective view of a training device 101 according to a second embodiment of the present invention, FIG. 8 is a plan view of the training device 101, FIG. 9 is a side view of a step 104 of the training device 101, and FIG. FIG. 10 is an explanatory diagram of how to use the training device 101.

As shown in FIG. 7, the training device 101 includes an elongated bar 102. The bar 102 is formed to be longer than the shoulder width of a trainer of a typical physique, and the end protrudes by several tens of centimeters on both sides of the trainer while the trainer rests on the shoulder. I do.

As shown in FIG. 8, the bar 102 has a bar main body 102a formed of a rigid material such as a metal, and annular connecting portions 102b are formed at both left and right ends thereof. A plurality of string-like elastic bodies 103 made of rubber or the like are inserted into each connecting portion 102b. An elastic tube 102c made of a resin material is attached to the outer peripheral surface of the bar main body 102a.

[0060] Reference numeral 104 denotes a step board, which is mounted on the floor surface and is formed of a rigid rectangular plate. As shown in FIG. 9, a sheet member 105 (a non-slip means) formed of a material having a high coefficient of friction to prevent the step 104 from slipping on the floor is attached to a lower surface of the step 104. Have been.

An annular connecting member 106 is provided upright at each corner on the upper surface of the step 104, and an elastic body 103 is connected to each connecting member 106 via a connecting ring 107. Each elastic body 103 is passed through the connecting portion 102b and the connecting ring 107, and both ends (not shown) are connected to each other.弹 The elastic body 103 is detachable from the connecting ring 107 and the connecting part 102b, and the size of the load applied to the bar 102 can be adjusted by changing the number of elastic bodies 103 or replacing it with another elastic body. can do.

Next, a method of using the training device 101 will be described with reference to FIG. When the trainer rides on the platform 104 and lifts the bar 102 while holding it horizontally on the shoulder, each of the elastic bodies 103 extends within the elastic limit, and a downward load is generated on both left and right ends of the bar 102. . Further, by twisting the bar 102 carried on the shoulder to the left and right, each elastic body 103 expands and contracts within the elastic limit, and loads opposite to the twist are generated at the left and right ends of the bar 102.

[0063] By repeatedly performing the squat operation of bending and stretching the knee while holding the bar 102 on the shoulder and twisting the bar 102 right and left during the operation, the muscle strength of the lower body and the trunk can be strengthened. Note that the bar 102 may be pulled up to the waist level with the rear hand and twisted right and left. When performing the squat operation, the operation of flexing and stretching the body slowly is effective because the load of the elastic body 103 acts on the upper body and the knee, which is effective.

By performing such an operation, particularly, quadriceps femoris, biceps femoris (hamstring), gastrocnemius and soleus (calf), latissimus dorsi, abdominal muscle, gluteus maximus, etc. can be trained. This will allow you to build the core of the body necessary for judo, and improve the balance of your body when performing techniques and competing.

[0065] In the training apparatus 101, since the load is applied to the bar 102 by the elastic body 103, the bar 102 can be made relatively lightweight. Therefore, compared to a training device that applies a load by weight (for example, a squat shaft, etc.), the β-force that works when twisted is small, so that excessive torsional force or twisting force does not act on the body, and it is safe and So fast! , Training in motion is possible.

[0066] Further, the training device 101 has an advantage that it has an extremely simple structure, is inexpensive to manufacture, and easy to move.

Further, since the magnitude of the load applied to the bar 102 can be known by measuring the power of the elastic body 103, highly reasonable training based on numerical grounds can be performed.

In the present embodiment, a force for attaching the elastic body 103 to the step 104 placed on the floor may be attached to the floor via appropriate attaching means. .

FIG. 22 to FIG. 24 show modifications of the second embodiment.

In the example shown in FIG. 22, a plurality of elastic bodies 103 and a plurality of connecting rings 107 provided therebetween are provided for each connecting member 106 of the connecting portion 102 b of the bar 102 and each connecting member 106 of the step platform 104. Arbitrarily increase or decrease the number of connecting rings 107 and elastic bodies 103 You can do it. In this way, the height from the step 104 to the bar 102 can be adjusted, so that a plurality of trainees with different heights can be accommodated. Further, by changing the number of the elastic bodies 103 or replacing the elastic bodies 103 with one having a different repulsive force, the magnitude of the load applied to the sensor 102 can be adjusted.

The example shown in FIG. 23 includes exercise amount display means 108 for calculating and displaying the exercise amount of the trainee. The exercise amount display means 108 includes a counter 109 for counting the number of times the bar 102 is moved up and down, a counting circuit 110 for calculating the amount of exercise based on the detection value of the counter 109, and a display for displaying the amount of exercise calculated by the counting circuit 110. With device 111

[0072] Note that the counting circuit 110 and the display device 111 may be designed specifically, or only a new personal computer may be created using a general personal computer. Although the displayed amount of exercise is not particularly limited, for example, the number of times of ascending and descending, total weight, kinetic energy (calories) and the like can be displayed. In this way, reasonable training based on numerical evidence can be performed.

In the example shown in FIG. 24, the step 104 is equally divided into a pair of left and right divisions 104a and 104b along a center line 112 extending in the front-rear direction, and is divided by a pair of hinges 113 provided at these boundaries. The portions 104a and 104b are rotatably connected, and the step 104 can be folded along the center line 112. By doing so, the step 104 can be folded and made compact, so that the transportability and the storage property are improved.

Note that the examples shown in FIGS. 22 to 24 may be implemented alone or in combination with one another as appropriate.

Next, a third embodiment of the present invention will be described. FIG. 11 is an overall perspective view of a training device 201 according to a third embodiment of the present invention, FIG. 12 is a side view of the training device 201, and FIG. 13 is an explanatory diagram of a method of using the training device 201.

[0076] The training device 201 is used by being connected between two fixed objects s, S arranged on both sides of a space where the trainee trains, and is larger than the distance between the fixed objects S, S. It has a short bar 202. This bar 202 is formed longer than the shoulder width of a trainer of a typical physique, and has an end when placed in front of the trainee. Force Protrude by several tens of cm on each side of the S trainer It should be noted that the fixed object S may use an existing one (for example, a column of another training device) or may be a specially designed one.

As shown in FIG. 12, the bar 202 has a bar body 202a formed of a rigid material such as a metal, and annular connecting portions 202b are formed on both left and right ends thereof. . A plurality of string-like elastic members 203 made of rubber or the like are attached to each connecting portion 202b via a connecting ring 204.

[0078] Each elastic body 203 is inserted into the connecting ring 204, is wound around the outer periphery of the fixed object S, and

(Not shown) are tied together. The elastic body 203 can be freely attached to and detached from the connecting ring 204 and the fixed object S. By changing the number of the elastic bodies 203 or replacing it with another elastic body,

The size of the load applied to 202 can be adjusted.

Next, a method of using the training device 201 will be described with reference to FIG. When the trainer holds the bar 202 with both hands and performs rotation, twisting, stepping on the body as an axis, loads opposing these operations are generated at the left and right ends of the bar 202.

[0080] The bar 202 can be freely moved within the elastic limit of each elastic body 203.

, Can strengthen the strength of the whole body. In particular, forearm muscles, biceps brachii, triceps brachii, quadriceps femoris, latissimus dorsi, etc. can be trained.

[0081] Further, in the training apparatus 201, since the elastic body 203 applies a load to the bar 202, the bar 202 can be made relatively lightweight. Therefore, since the inertial force that works when twisted is small, excessive torsional force or torsional force does not act on the body, and it is possible to train safely and quickly while moving.

[0082] Since the trainee can move the bar 202 freely and quickly, the trainee can perform training with an action and image similar to the actual judo approach.

For example, by pressing the bar 202 with the left hand while stepping with the right foot, pulling the bar 202 with the right hand, and twisting the body to the right, the same operation as the large outside mowing on the left can be performed.

[0084] Further, while stepping on the right foot and the left foot in this order, pressing the bar 202 with the right hand, pulling the bar 202 with the left hand, and twisting the body 180 ° to the left, it is possible to perform the same operation as the right carrying technique. .

[0085] The training device 201 has an extremely simple structure and is inexpensive to manufacture. Both have the advantage that they are lightweight and easy to move.

[0086] Also, by measuring the power of the elastic body 203, it is possible to know the magnitude of the load applied to the bar 202, and thus it is possible to perform highly reasonable training based on numerical evidence. Wear.

[0087] There is also an advantage that the training can be performed at any place as long as there is a fixed object connecting the bar 202.

Next, a fourth embodiment of the present invention will be described. FIG. 14 is an overall perspective view of a training device 301 according to a fourth embodiment of the present invention, FIG. 15 is a plan view of the training device 301, and FIG. 16 is an explanatory diagram of a method of using the training device 301.

As shown in FIG. 14, the training device 301 is used in connection with a plurality of fixed objects S ′, S ′, which are arranged around the space where the trainee trains. And a torso winding part 302 wound around the trainee's torso.

[0090] The fixed object S 'may use an existing one (for example, a column of another training device) or may be a specially designed one.

[0091] As shown in Fig. 15, the body winding part 302 includes a flexible tube 303 formed of a resin material, and a chain 304 inserted into the tube 303 and having both ends protruding from the tube 303. And a hook-shaped locking member 305 attached to one end of the chain 304.

[0092] The body winding part 302 is formed in an elliptical shape, and a plurality of string-like elastic bodies 306 made of rubber or the like are provided on both ends in the major diameter direction of the connecting ring 307 of the pair. It is linked via 307. Both ends of each elastic body 306 are connected to each other, passed through connecting rings 307, 307, and connected to a fixed object S ′ via a hook-shaped connecting member 308 and a wire 309 so as to be vertically movable.

[0093] The elastic body 306 is detachably attached to the connecting ring 307 and the connecting member 308. By increasing or decreasing the number of the elastic bodies 306 or replacing it with another elastic body, a large load is applied to the body winding part 302. Can be adjusted.

Next, a method of using the training device 301 will be described. Wrap the torso 302 around the trainee's torso and tighten it to an appropriate strength. The hook 305 is hooked at an appropriate position at the other end of the chain 304 and locked.

As shown in FIG. 16, when the trainee twists the torso to the left and right, each elastic body 306 expands and contracts, and a load contrary to the twist acts on the torso winding part 302. Since this load acts directly on the trainee's torso, the trunk muscle strength can be surely strengthened. In particular, it can train rectus and oblique muscles.

[0096] In addition, by performing a motion such as putting out or pulling the trainee's power forward and backward at the same time as torsion, the training can be performed with a motion and image similar to the actual judo approach.

[0097] The training device 301 has an extremely simple structure, is advantageous in that it is inexpensive to manufacture and easy to move because it is lightweight.

[0098] Further, since a load is applied by the elastic body 306, the body winding part 302 is lightweight and has a small inertial force acting when twisted. Therefore, since excessive torsional force and torsional force do not act on the body, training with safe and quick motion is possible.

[0099] Further, there is an advantage that training can be performed at any place as long as there is a fixed object connecting the body winding part 302.

[0100] Further, since the magnitude of the load applied to the body winding part 302 can be known by measuring the power of the elastic body 306, it is possible to perform highly reasonable training based on numerical evidence. Monkey

[0101] The configuration of the present invention is not limited to those described in each of the above embodiments. Various modifications can be made to the above embodiment without departing from the spirit of the present invention.

[0102] The training device of the present invention can also be used for training other than judo.

Industrial applicability

[0103] In the training device of the first invention, when the trainee grasps the pressing operation portion with both hands and presses forward, a load is generated at both ends of the bar in a direction opposite to the pressing direction. By repeating the operation in which the trainee presses the pressing operation unit forward so as not to lose the load, the muscle strength of the upper arm and the trunk can be strengthened. Also, since the pressing operation part is unstable in rotation, it can train the wrist and strengthen the forearm muscle strength. Can do. In addition, since it is necessary to firmly hold the pressing operation unit with both hands and push both arms forward, it is possible to enhance grip strength and shoulder muscle strength. Further, when pressing the pressing operation unit, it is necessary to step on the foot to balance, so that the muscle strength of the lower body as well as the upper body can be strengthened.

[0104] In the training device of the second invention, a downward load is generated at both ends of the bar when the trainee lifts the bar on the shoulder, and the bar held on the shoulder is moved to the left and right. The twist causes a load on the bar that is contrary to the twist. By repeatedly performing the squat operation of bending the knee while holding the bar on the shoulder and twisting left and right during the operation, the strength of the lower body and the trunk can be strengthened. The same effect can be obtained even if the bar is pulled up to the waist level with the rear hand and twisted right and left.

[0105] In the training device of the third invention, when the trainee holds the bar with both hands and performs rotation, twisting, stepping on the body, etc., a load contrary to these operations is generated in the bar. . With this training device, since the movement of the bar is not restricted, the strength of the whole body can be strengthened, and the training can be performed with the motion and image similar to the actual judo approach.

[0106] In the training device of the fourth aspect of the present invention, the trainee twists the torso left and right, so that a load contrary to the twisting is generated in the torso winding portion. Since this load acts directly on the trainee's torso, the strength of the trunk can be surely strengthened. In addition, since the trainee can simultaneously perform twisting such as putting the foot forward or pulling the foot backward, the training can be performed with the motion and image similar to the actual judo approach. .
