[0045] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0046] like Figure 1-6 As shown in the figure, this application provides a squat posture correction machine, including a frame 100, a foot pedal device and a foot pedal connecting device 200; the foot pedal device is installed at the bottom of the frame 100 and can move back and forth along the frame 100; the foot pedal device includes an adjustment plate 1, and a first rotating shaft 101 is installed at the center of the adjustment plate 1, which rotates relative to the horizontal plane with the first rotating shaft 101 as the central axis; the foot pedal connecting device 200 is installed on the left and right sides of the foot pedal device 200 and is used to connect the frame 100 and the foot pedal device.

[0047] During implementation, a display panel can be set up corresponding to the foot pedal device to show the rotation status of the foot pedal device, allowing real-time observation of the leg and foot status during squats, thereby increasing the standard of training.
