Description

Technical Field

[0001] This invention relates to the technical field of squatting auxiliary training devices, and particularly to a sports training device with foot braces and its training method. Background Technology

[0002] In the field of fitness training, squatting is a common way to exercise lower limb strength and strengthen core muscles. It is mainly carried out through deep squats, a classic fitness exercise. It mainly involves standing with your feet apart, bending your knees and squatting down to a specified depth before standing up. It exercises the muscles in the thighs, glutes, and core, enhances lower limb strength and body stability, and also improves cardiovascular function. It is a very basic and efficient training method in daily fitness and strength training.

[0003] Based on the above, the position and spacing of the load-bearing pedals in most existing squat training equipment are fixed, making it difficult to adapt to the physical conditions of trainees of different heights and body types. The protective measures are relatively simple, and most of them rely solely on the trainee to control the squatting range, which can easily lead to oversquatting. Furthermore, they cannot provide timely and effective protection when the trainee is exhausted, posing certain safety hazards. At the same time, it is difficult to quickly adjust the training intensity according to one's own needs. Summary of the Invention
