As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0024] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

The lower waist support plate 301 is rotatably installed between the first rotating mounting seat 206 and the second rotating mounting seat 207.

[0034] Specifically, the first cylinder 208 and the second cylinder 209 are synchronous cylinders. The first cylinder 208 and the second cylinder 209 extend and retract synchronously to adjust the height of the floating plate 205, thereby adjusting the height of the lower waist support plate 301.

[0037] When backbend training is required, pull down the limiting frame 11 and stretch the two first springs 12 to disengage the top edge of the limiting frame 11 from the limiting rotating seat 8. Rotate the backbend support plate 301 so that the convex arc surface of the backbend support plate 301 faces upward and the leg pressing assembly 302 faces downward. At this time, the top edge of the limiting frame 11 is opposite to the first strip groove 9. Release the limiting frame 11, and the limiting frame 11 will be engaged in the first strip groove 9 under the action of the two first springs 12. At this time, the backbend leg pressing mechanism 3 is in the backbend state, and the trainee can use this embodiment to perform backbend training.

[0042] In addition, a protective pad is laid on the top surface of the support plate 407.

[0043] When the trainee needs to stand up, the third cylinder 403 is extended to push the reinforcing rod 406, thereby adjusting the rotation of the auxiliary frame 405. The support plate 407 then lifts the trainee's head to help the trainee stand up.
