Description

[0001] The present invention relates to a training device and a method for operating the training device.

[0002] Training devices and rehabilitation equipment are used in sports and leisure facilities, such as gymnasiums, fitness centers, rehabilitation centers, clinics, and similar facilities. In such facilities, it is stipulated that athletes or users (hereinafter referred to as trainers) perform gymnastic or rehabilitative series of exercises to improve physical fitness and / or health, also referred to as training units, which vary according to parameters such as the type of training or rehabilitation, the build of the trainer, their health condition, the goals to be achieved, etc.

[0003] Generally, after examining the characteristics of the trainer, a series of exercises, i.e., a training plan, is created by a coach or instructor, in which the execution conditions of the exercises are also defined. This training plan actually constitutes the program to be executed by the trainer and is usually accompanied by a written list that the trainer carries with them during the training unit for checking the execution of the exercises performed by them. Different training plans mainly differ in the number of exercises, as well as the order, duration, and intensity of the exercises.

[0004] Advantageously, the trainer completes a full-body training to ensure balanced muscle building in the body and avoid the risk of injury caused by weaker muscle groups. This usually includes various exercises, also referred to hereinafter as training movements, which exercise all the major muscle groups of the body.

[0005] Professionals understand full-body training as a training in which exercises from each of the following categories are completed: upper body pulls, upper body pushes, lower body pulls, lower body pushes, hip closures, and hip openings. The upper body pull category includes exercises of pulling movements against resistance through the upper body muscle tissue, such as seated rows or lat pulldowns. The upper body push category includes exercises of pushing movements against resistance through the upper body muscle tissue, such as chest presses or shoulder presses. The lower body pull category includes exercises of pulling movements against resistance through the lower body muscle tissue, such as leg curls. The lower body push category includes exercises of pushing movements against resistance through the lower body muscle tissue, such as leg extensions or leg presses. The hip closure category includes exercises of closing the hip angle against resistance through the trunk muscle tissue, such as abdominal presses. The hip opening category includes exercises of opening the hip angle against resistance through the trunk muscle tissue, such as back extensions. By completing at least one exercise from each of the above categories, effective full-body training can be ensured.

[0006] Generally, full-body training is completed on different devices specialized for this purpose. For example, a leg press machine is used to train the legs, and a flat bench with a barbell rack is used for bench presses (chest presses). However, since there are usually multiple trainers in a fitness center at the same time, waiting times may occur when using different machines.

[0007] One possible alternative is to provide a single training device with which a full-body training can be accomplished.

[0008] One problem with full-body training is the different settings that have to be made on each machine. Usually, on each machine, in addition to the resistance, the seat or the operating element has to be adjusted according to the height of the trainee. Thus, the training plan includes not only the corresponding exercises, but also the number of sets and repetitions thereof and the settings that have to be made on the machine. For a training device that allows full-body training on the same machine, although the trouble of switching to the next machine is eliminated, for this training device, the positions of the seat and the operating element also have to be individually adapted for each exercise.

[0009] WO 2020 / 212223 A1 discloses a strength training device for strengthening the muscle strength of the upper body region and / or the leg or trunk muscle tissue. The strength training device includes two seats and three manually operable operating elements, and the operating elements are coupled to at least one resistance-generating unit through a lever mechanism. The trainee can thus perform different exercises using the corresponding operating elements while sitting on the corresponding seat. For this purpose, the lever mechanism of the operating element is changed accordingly by a control unit. The disadvantage of WO 2020 / 212223 A1 is that the exercises performed thereon are limited because its structure, for example, does not allow leg press and supported rowing, both of which are essential exercises for full-body training. In addition, the user has to mechanically adjust the seat according to his height and the exercises to be performed separately. This is not only complicated and laborious for the trainee, but also very dangerous because he risks injury when setting it incorrectly. In addition, it is not clear how a digital coach can continuously accompany the trainee when the trainee not only has to change the seat, but also has to leave the seat almost after each exercise in order to adjust the seat.

[0010] EP 2174694 A1 discloses a system for creating and editing a training plan, in which the execution of the exercises is monitored by a computer and the training results are directly incorporated into the training plan. Thus, the recording of the training results is eliminated. However, the comfort of performing all the exercises on the same device and being able to exclusively reserve the device during the exercise is eliminated. Switching from one device to another has many disadvantages. First, the trainee has to first perform a surface cleaning and disinfection on each device. Then, he may have to wait at the next device until the current user finishes his exercise. Then, he may have to leave his device before finishing because the subsequent user urges him. In addition, each time he changes the device, he loses his digital coach and has to log in again on each device. These are just the direct disadvantages of use. Economically, it is obvious that in a design for this purpose, with 6m 2Full-body training on a training device with space requirements and a cost of 20,000 € can be installed closer to or even directly near the trainee, while for full-body training with multiple dedicated machines, space requirements of 100 m are estimated and a total cost of 120,000 €, which only applies to large fitness centers. 2 The space requirements and the total cost of 120,000 € only apply to large fitness centers.

[0011] GB 2510136 A discloses a training device having a circular frame on which operating elements are fixed. The circular frame can be rotated by a ground unit to bring the operating elements to respective training positions.

[0012] WO 2009 / 143808 A1 discloses a training device having at least one cable, the first end of which is coupled to a holding element and the second end of which is coupled to an electric motor. The cable is guided through a pulley during this process, the pulley being arranged on a trolley that can move on an arcuately curved guide rail.

[0013] Therefore, the object of the present invention is to eliminate the disadvantages of the prior art and to provide a training device and a method for operating a training device that are capable of performing a full-body strength training that is ideally matched to the trainee.

[0014] According to the present invention, this object is solved by a training device according to claim 1 and a method for operating said training device according to claim 13. Preferred embodiments of the present invention are given in the dependent claims.

[0015] The present invention relates to a training device comprising a single adjustable seat for a trainee; and first, second and third operating elements. Each operating element is individually configured to be moved by the trainee sitting on the seat from a starting position to an end position and back again during training. The training device further comprises: a first force transmission unit connected to the first operating element; a second force transmission unit connected to the second operating element; and a third force transmission unit connected to the third operating element. In addition, the training device comprises at least one training resistance unit connected to the force transmission units; and a control unit. The seat comprises a seat surface and a backrest, wherein the seat surface and the backrest are configured to be adjustable independently of each other. In addition, the training device according to the present invention differs from the prior art in that the control unit is adapted to control the training resistance unit and to adjust the position of the seat surface or the backrest or the position of at least one operating element or a combination thereof.

[0016] In the context of the present invention, the term "training resistance unit" is understood to mean a unit that exerts a resistance on the operating element such that the trainee can perform the exercises to be carried out on the operating element against the resistance.

[0017] The advantages of the training device according to the present invention are that the control unit automatically adapts the corresponding operating elements and seats for the exercises to be completed respectively, whereby full-body training can be carried out on one machine, thus eliminating the trouble of waiting for an idle training device when changing training exercises. Another advantage of the training device according to the present invention is that the trainer does not have to remember the positions of the seats and operating elements for each exercise, because the control unit completes the adaptation for him. Thereby, the risk of injury caused by mispositioned operating elements or incorrectly adjusted seats is avoided. Another advantage of the training device according to the present invention is that full-body training can be carried out in a shorter time, because the resetting of the training device is eliminated, and the training device thus achieves particularly efficient training. In addition, through the automatic adaptation of the training device, the threshold for inexperienced trainers such as the elderly is also reduced, because the training device independently completes the configuration. The ability to reserve the device during full-body training further improves comfort and simplifies the planability of training. Another advantage of the training device according to the present invention including a single seat is that full-body training can be carried out without the trainer having to leave the seat of the training device, because the control unit automatically adapts the corresponding operating elements and seats for the exercises to be completed. This improves the comfort of training and further reduces the floor area occupied by the training device, whereby it is also suitable for home use or small training rooms. Another advantage of the training device according to the present invention including three operating elements is that the training movements can be better distributed to the respective operating elements, so that these operating elements require less adaptation and / or achieve better force transmission.

[0018] As described above, the seat includes a seat surface and a backrest. In the context of the present invention, this means that the seat surface and the backrest can be directly connected to each other or only indirectly connected to each other to form a seat.

[0019] In an embodiment where the seat surface and the backrest are not directly connected to each other, a channel is formed between the seat surface and the backrest, and the channel is defined by the seat surface and the backrest. This structure allows the operating element to move through the channel between the seat surface and the backrest. For example, when it should rotate under the seat to change its position. This structure enables a training in which the trainer does not have to get up from the seat surface when the operating element is switched from a first training exercise to a second training exercise.

[0020] In a preferred embodiment of the present invention, the first operating element is configured such that it can train the muscle tissues of the legs, upper torso, arms or shoulders of the trainer. In addition, the second operating element is configured such that it can train the muscle tissues of the legs and lower torso of the trainer. In addition, the third operating element is configured such that it can train the muscle tissues of the shoulders and upper torso of the trainer.

[0021] Through this distribution, all the main muscle groups of the body can be effectively trained.

[0022] The leg muscle tissue particularly includes the following muscles: quadriceps femoris, gluteal muscles, soleus, gastrocnemius, biceps femoris, and sartorius.

[0023] The upper torso muscle tissue particularly includes the following muscles: pectoralis major, pectoralis minor, deltoideus, teres major, teres minor, and latissimus dorsi.

[0024] The arm muscle tissue particularly includes the following muscles: triceps brachii and biceps brachii.

[0025] The lower torso muscle tissue particularly includes the following muscles: erector spinae, iliocostalis, longissimus, spinalis, rectus abdominis, and obliquus externus abdominis.

[0026] The shoulder muscle tissue particularly includes the following muscles: pectoralis major, pectoralis minor, and deltoideus.

[0027] For this purpose, it is preferable to perform at least one training exercise selected from leg press, rowing pull, and chest press on the first operating element. It is preferable to perform at least one training exercise selected from leg curl, leg extension, abdominal press, and back extension on the second operating element. It is preferable to perform at least one training exercise selected from shoulder press and lat pulldown on the third operating element. The above training exercises particularly exercise the following muscles:

[0028] Leg press: quadriceps femoris, gluteus maximus, soleus, and gastrocnemius.

[0029] Rowing pull: teres major, teres minor, latissimus dorsi, deltoideus, and biceps brachii.

[0030] Chest press: pectoralis major, pectoralis minor, deltoideus, and triceps brachii.

[0031] Leg curl: biceps femoris, sartorius, and gastrocnemius.

[0032] Leg extension: quadriceps femoris and gluteal muscles.

[0033] Abdominal press: rectus abdominis and obliquus externus abdominis.

[0034] Back extension: erector spinae, iliocostalis, longissimus, and spinalis muscles.

[0035] Shoulder press: deltoid, triceps brachii, pectoralis major, and external oblique abdominal muscles.

[0036] Lat pulldown: latissimus dorsi, trapezius, teres major, teres minor, and biceps brachii.

[0037] By distributing the training movements to three operating elements, all major muscle groups of the body can be trained particularly effectively. In particular, the movements of shoulder press and / or lat pulldown can be performed more effectively by the third operating element in this way.

[0038] In a preferred embodiment of the invention, the seat is longitudinally arranged between the first and the third operating elements, and the second operating element is arranged transversely to the seat in the longitudinal direction. The advantage of this arrangement of the operating elements is that the trainer can conveniently enter the training device from the side, i.e., transversely, and the operating elements do not obstruct him during this process.

[0039] Preferably, at least one operating element is also configured as a fixing element for fixing the trainer to the seat. Particularly preferably, the second and third operating elements are also configured as fixing elements for fixing the trainer to the seat.

[0040] Since in some training movements, the own body weight is not sufficient as a counterweight for the resistance of the training device, it may be necessary to fix the trainer. The advantage of fixing the trainer by the operating element is that no additional fixing elements are required, especially no handles that the trainer has to hold. This enables the trainer to fully focus on performing the training movement without having to hold a handle or the seat during this process. In addition, the necessity of fixing by straps on the seat, which is sometimes uncomfortable, is also eliminated. Last but not least, with the above preferred embodiment, the risk of injury due to incorrect trainer fixation is reduced.

[0041] In a preferred embodiment of the invention, one of the operating elements is configured to pivot about a horizontal rotation axis oriented perpendicular to the longitudinal direction, preferably pivotable 360°. Particularly preferably, the second operating element is configured to pivot 360° about a horizontal rotation axis oriented perpendicular to the longitudinal direction. The advantage of this particularly preferred embodiment is that the second operating element is suitable for performing a variety of training movements due to the rotational freedom about the rotation axis, and these training movements also include movements in the opposite direction. Therefore, by rotating about the rotation axis, the second operating element can be used for both the training movement of leg curl and leg extension. In addition, the second operating element is suitable for both the training movement of abdominal press and back extension.

[0042] Preferably, the adjustable seat includes a seat surface and a backrest, both of which are configured to be adjustable independently of each other. Particularly preferably, the seat surface or the seat can be moved vertically and horizontally along the longitudinal axis. In addition, in a preferred embodiment, the seat surface can also be tilted about a transverse axis, wherein the transverse axis is perpendicular to the vertical axis and perpendicular to the longitudinal axis. The seat can thus be tilted or lifted relative to the horizontal plane.

[0043] By the separate adjustability of the seat surface and the backrest, the seat can be ideally adapted to the different body proportions of the trainer, so that each trainer can perform all the exercises to be completed in a position ideal for him. The backrest can be moved horizontally and can also change its inclination relative to the seat. Thus, optimal adjustment can be made for each exercise and each trainer.

[0044] In a preferred embodiment of the present invention, the total weight of the training device is less than 800 kg. This facilitates the transportation and installation of the training device. In addition, due to the light structure, the training device can also be placed on higher floors of buildings, which usually have lower load-bearing capacities than the ground floor.

[0045] In a preferred embodiment of the present invention, the training device includes a second training resistance unit and preferably a third training resistance unit, wherein each training resistance unit is respectively connected to a corresponding force transmission unit. By assigning each force transmission unit to a separate training resistance unit, the power required by the training resistance unit and its structure can be precisely adapted to the training movements performed on the corresponding operating element. For example, for the training movement performed on the second operating element, such as leg flexion and extension, less training resistance is required than on the first operating element (on which leg press can be completed). Therefore, by directly assigning each operating element and its associated force transmission unit to a separate training resistance unit, the power required by it can be optimized, which results in significant cost savings.

[0046] Preferably, the training device is modularly constructed, and the weight of each module is less than 300 kg.

[0047] By the modular construction, the individual components of the training device can be easily transported by two strong people without the need for transport aids such as forklifts, manual pallet trucks or lifts during this process.

[0048] In a preferred embodiment of the present invention, at least one force transmission unit is configured as a rocker. Particularly preferably, all force transmission units are configured as rockers.

[0049] The preferred embodiment in which the force transmission unit is configured as a rocker enables the operating element to move under load in respectively opposite movement directions without changing the connection points of the operating element or the force transmission unit during this process.

[0050] For example, for a cable device with a bolt counterweight, it is necessary to change the guide pulley and thus the connection point of the traction rope in order to perform, for example, a standing biceps curl and a standing triceps dip.

[0051] The structure of the force transmission unit of the rocker enables the performance of shoulder presses and lat pulldowns with the same operating element without having to modify the training device in the process.

[0052] Preferably, the training resistance unit includes an electric motor, preferably a servo motor or an AC motor, particularly preferably a servo motor.

[0053] The advantage of using a servo motor or an AC motor as a resistance source is that the space - occupying counterweight tower is eliminated. In addition, the training resistance can be adjusted steplessly and automatically. The advantage of a preferred servo motor is also that the training resistance can be adjusted very precisely, whereby the training movement can be monitored and controlled more precisely.

[0054] The invention also relates to a method for operating a training device by a trainer, comprising the following steps:

[0055] a) Providing a training device (1), preferably a training device (1) according to any one of claims 1 - 11, comprising a control unit (83), an adjustable seat (5), a first operating element (11), a second operating element (13) and a third operating element (15).

[0056] b) Verifying the trainer (3) at the control unit (83), thereby loading a predefined training plan (85) into the control unit (83), and adjusting the position of the seat (5) and the position of at least one operating element (11, 13) by the control unit (83) according to the predefined training plan (85).

[0057] c) Performing a first training movement (91), wherein the trainer (3) moves one of the operating elements (11, 13) at least once from a starting position to an end position and back again according to the training plan (85).

[0058] d) Adjusting the position of the seat (5) and the position of at least one operating element (11, 13) by the control unit (83) according to the predefined training plan (85).

[0059] e) Performing at least one additional training movement (99), wherein the trainer (3) moves one of the operating elements (11, 13) at least once from a starting position to an end position and back again according to the training plan (85).

[0060] f) Optionally repeating steps d) and e) until the predefined training plan (85) is completed.

[0061] The advantages of the method according to the present invention are that the control unit automatically adapts the corresponding operating elements and the seat for the exercise to be completed respectively, whereby full-body training can be carried out on one machine without having to leave the training device or switch to another training device during this process. Another advantage of the training device according to the present invention is that the positions of the seat and the operating elements for each exercise are automatically adapted by the control unit, and the trainer does not have to remember these positions separately. Thereby, the risk of injury caused by mispositioned operating elements or incorrectly adjusted seats can be avoided or minimized. By automatically setting the position and training resistance, the training results can be evaluated with higher quality, and the training achievements from one training session to the next can be compared more precisely.

[0062] Another advantage of the training device according to the present invention is that full-body training can be carried out in a shorter time by eliminating the manual resetting of the training device. In addition, through the combination of the training plan and the control unit, the training device can be precisely adapted to the needs of the trainer, thereby avoiding overtraining and thus also reducing the risk of injury. Continuous digital guidance, automatic and personalized setting of the device to the trainer, and the ability to reserve the training device during full-body training create a new level of comfort, which will motivate many people to train. A 15-fold reduction in space requirements and a 5-fold reduction in costs will enable a more detailed distribution of these devices, thereby achieving a reduction in time consumption in addition to the improvement in comfort.

[0063] In the method according to the present invention, the training device preferably includes a third operating element. Particularly preferably, a first training movement selected from the group consisting of chest press, rowing pull, and leg press is performed on the first operating element. Particularly preferably, a second training movement selected from the group consisting of leg curl, leg extension, back extension, and abdominal press is performed on the second operating element. Particularly preferably, a third training movement selected from the group consisting of shoulder press and lat pulldown is performed on the third operating element.

[0064] As already described for the training device, the three training movements mentioned above involve all the major muscle groups of the human body.

[0065] In a preferred embodiment of the method according to the present invention, the training plan is loaded from a storage unit, particularly preferably from a cloud-based storage unit, onto the control unit.

[0066] The advantage of the cloud-based storage unit is that it eliminates the need for a local server for storing training plans in the training environment or the building where the training device is located. Thereby, the space and energy costs that would be incurred in the case of a local server can be saved.

[0067] Preferably, the training plan includes at least one parameter selected from the group consisting of movement sequence, training resistance, duration of each stage of the movement, movement amplitude (range of motion), seat configuration data, movement dynamics, and number of movement repetitions.

[0068] These parameters all have an impact on the training intensity and thus allow for personalized adjustment of the training stimulus.

[0069] The present invention will be explained in more detail below with reference to some embodiments shown in the accompanying drawings. If alternative embodiments differ only in individual features, the same reference numerals are used for the features that remain unchanged. The figures show purely schematically:

In addition, the training device 1 includes a first operating element 11, a second operating element 13, and a third operating element 15. The first operating element 11 includes a first connecting rod 17 and two handles 19 for the hands 20 of the trainer 3 arranged on the first connecting rod 17. The first operating element 11 also includes a second connecting rod 21 and a plate 23 arranged on the second connecting rod 21, on which the feet 24 of the trainer 3 can be positioned. In Figure 1 and Figure 2 , the first operating element 11 is folded because it is not used for the intended training movement. The second operating element 13 includes a third connecting rod 25 and a contact element 27 fixed to the third connecting rod 25, which contacts the trainer 3. In Figure 1 , the contact element 27 contacts the upper region of the back 29 of the trainer 3. The third operating element 15 includes a fourth connecting rod 31, two handles 33 for the hands of the trainer 3 arranged on the fourth connecting rod 31, and two restraint elements 35 arranged on the handles 33. In Figure 1 , the third operating element 15 is folded upward because it is not used for the currently performed training movement. The training device 1 also includes a side box 37 covered with a cover plate 39; a front box 41 having a cover plate 43 (not shown); a rear box 45 having a cover plate 47; and a seat bracket 49. The backrest 9 is arranged on the rear box 45 and can move longitudinally towards or away from the trainer 3. In addition, the backrest 9 can also be tilted so that it leans more steeply or more flatly against the rear box 45. The seat surface 7 is fixed to the seat bracket 49 and can move up and down in the vertical direction, move forward towards the first operating element 11 and move backward towards the backrest 9 along the longitudinal axis. In addition, the seat surface 7 can also be tilted towards the first operating element 11 or lifted towards the backrest 9. The training device 1 also includes a screen 51 on which information about the current training movement is displayed to the trainer 3. The corresponding information includes, for example, the current number of completed repetitions, the programmed number of repetitions, the number of completed sets, the programmed number of sets, the current position of the operating element, the range of motion to be completed, or the next training movement to be completed. The screen 51 is fixed to a track (not shown here) by a suspension member 53 and can move forward and backward longitudinally along the track so that the trainer 3 can clearly read the information displayed on the screen 51.

[0080] Figure 3A side view showing a preferred embodiment of the training device 1, in which the cover plate 39 at the side box 37 has been removed so that the internal structure is visible. The first operating element 11 is connected to the first force transmission unit 55, where the first force transmission unit 55 is configured here as a rocker with a movement range of approximately 90°. The first force transmission unit 55 is connected to the first training resistance unit 59 through the first transmission mechanism 57. The first training resistance unit 59 is configured here as a servo motor. The second operating element 13 is connected to the second force transmission unit 61, where the second force transmission unit 61 is configured here as a rocker with a movement range of 360°. The second force transmission unit 61 is connected to the second training resistance unit 65 through the second transmission mechanism 63, where the second training resistance unit 65 is also configured as a servo motor. The third operating element 15 is connected to the third force transmission unit 69, where the third force transmission unit 69 is configured here as a rocker with a movement range of approximately 90°. The third force transmission unit 69 is connected to the third training resistance unit 73 through the third transmission mechanism 71, where the third training resistance unit 73 is also configured as a servo motor. To reduce the load on the first and third training resistance units 59, 73 caused by the weight of the first and third operating elements 11, 15, the first and third force transmission units 55, 69 are fixed to the connection points 79, 81 by springs 75, 77 respectively. Figure 3 Also shown is the control unit 83, which is installed in the side box 37 and controls the positioning of the seat surface 7, the backrest 9, the three operating elements 11, 13, 15 and the training resistance units 59, 65, 73 from there. The positions of the three operating elements 11, 13, 15 are adjusted here by the three training resistance units 59, 65, 73.

[0081] Figure 4Schematic diagram showing a preferred embodiment of the method according to the present invention. At the start of training, the trainee 3 sits on the seat surface 7 of the seat of the training device 1, registers at the control unit 83 of the training device 1, and during this process confirms the reservation created by him on this device. After successful registration, the control unit 83 loads the training plan 85 from the cloud-based storage unit 87 onto the control unit 83 and calls the first training device configuration 89 stored therein. In the first training device configuration 89, the training device 1 is set for the first training movement 91 (here, back extension). During this process, the first operating element 11 moves backward to provide movement space for the training movement, and the third operating element 15 moves upward. In addition, the seat surface 7 moves forward so that it is at the height of the rotation axis of the second operating element 13 and is adjusted in height according to the height of the trainee 3. For this purpose, the second operating element 13 moves under the seat 5 through to the back of the trainee 3 and is adapted in height according to the height of the trainee 3. During this process, the digital coach instructs the trainee 3 to slightly lift his legs. The resistance used when the operating element 13 moves is so low that it will not hurt anyone. The digital coach signals to the trainee 3 that the configuration of the training device 1 is complete and that he can start the first training movement 91. The trainee 3 starts the first training movement 91 by applying pressure to the second operating element 13 with his back. During the training movement of back extension, the trainee 3 moves the second operating element 13 forward and backward along the path 93 predetermined for this purpose by the training plan 85 until he reaches the number of repetitions predetermined by the training plan 85. During this process, if the control unit recognizes the necessity (for example, when the trainee 3 is fatigued), the control unit 83 can adjust the movement amplitude along the path 93 and whether the resistance applied to the second operating element 13 is increased or decreased. When the trainee 3 has completed the first training movement 91 of back extension according to the training plan 85, he can remain sitting on the seat surface 7 while the control unit 83 configures the training device 1 for the next training movement 99. For this purpose, the control unit 83 calls the second training device configuration 95 and configures the training device 1 accordingly for the second training movement 99 (here, high pulley row) during the transition phase 97. During the transition phase 97, first the second operating element 13 is rotated backward so that it can rotate downward between the seat surface 7 and the backrest 9 and continue to move forward through under the seat toward the first operating element. The seat surface 7 with the trainee 3 sitting thereon moves backward toward the backrest 9. At the end position of the seat surface 7, the back of the trainee 3 sitting on the seat surface 7 touches the backrest 9. During this process, the second operating element 13 fixes him on the seat surface 7 by applying pressure to his thighs. Finally, the third operating element 15 is moved from the raised position to the starting position for high pulley row adapted to the height of the trainee 3. After the end of the transition phase 97, the trainee 3 can now complete the second training movement 99 of high pulley row on the training device 1.For other training exercises predefined by the training program 85, the training device 1 is set for the next training exercise in another conversion phase, while the trainee 3 does not need to leave the seat during this process.

[0082] Figure 5 Shows the trainee 3 during a back extension exercise. The trainee 3 is sitting on the seat surface 7 of the adjustable seat 5 during this process. During the back extension exercise, the second operating element 13 moves along a circular path 101 around the pivot point 103. The pivot point 103 is at the height of the hip joint of the trainee 3 during this process. To achieve an ideal exercise execution, the second operating element 13 must be adapted to the body proportions of the trainee 3. For this purpose, the length of the second operating element 13 can be adapted to the body proportions of the trainee 3 along the lever path 105, such that the contact element 27 is arranged at the height of the scapulae of the trainee 3. For this purpose, the seat surface is adjusted along the seat height axis 107 and the seat longitudinal axis 109, such that the hip of the trainee 3 coincides with the pivot point 103 of the second operating element 13. The adaptation of the positions of the seat surface 7 and the second operating element 13 and the body proportions of the trainee are necessary to avoid incorrect loading of the trainee 3 during training.

[0083] Figure 6 Shows a perspective view of the training device 1, where the trainee 3 is performing a lat pulldown exercise. During this process, the trainee 3 is sitting on the seat surface 7 and holds the handle 33 of the third operating element 15 with his hand 20. During the lat pulldown exercise, the handle 33 of the third operating element 15 moves from the starting position (above, shown) to the end position (below, not shown) against the resistance and then returns again. If the resistance is greater than the own weight of the trainee 3, he will be lifted from the seat surface 7 during the execution of the exercise and will perform a chin-up instead of a lat pulldown. To fix the trainee 3 on the seat surface 7, the second operating element 13 is positioned such that the contact element 27 of the second operating element 13 contacts the upper side of the leg of the trainee 3 and thereby prevents the trainee 3 from being lifted from the seat surface 7.

[0084] Figure 7 Shows a perspective view of the training device 1, where the trainee 3 is performing a rowing pull exercise. During this process, the trainee 3 is sitting on the seat surface 7 and holds the handle 19 of the first operating element 11 with his hand 20. During the rowing pull exercise, the handle 19 of the first operating element 11 moves from the starting position (away from the chest, not shown) to the end position (close to the chest, shown) against the resistance and then returns again. Even at a low resistance, the trainee 3 will apply too little of his own weight and will be pulled away from the seat surface 7. To fix the trainee 3 on the seat surface 7, the third operating element 15 is positioned such that the restraint element 35 on the handle 33 contacts the chest of the trainee 3 and thereby prevents the trainee 3 from being pulled away from the seat surface 7. Figure 8Side view showing a preferred embodiment of the training device 1, in which the trainer 3 performs a chest press (bench press) exercise. For this purpose, the trainer 3 is seated on the seat surface 7, with the back 29 in contact with the backrest 9. In the chest press exercise, the hands 20 of the trainer 3 grip the handle 19 of the first operating element 11 and move it from the starting position (shown) to the end position (arms extended forward, not shown) against resistance and then back again. To perform the chest press exercise, the first connecting rod 17 of the first operating element 11 folds upwards (oriented substantially parallel to the ground) and is arranged such that the trainer 3 pushes the handle forward along a path extending substantially parallel to the ground until the elbows are extended.

For this purpose, the trainer 3 is seated on the seat surface 7, with the back 29 in contact with the backrest 9. In the leg press exercise, the trainer 3 places the feet 24 on the plate 23 and moves it from the starting position (not shown) to the end position (shown) against resistance and then back again. The plate 23 is connected to the first operating element 11 by means of a second connecting rod 21 during this process.
