[0002] With the acceleration of modern life pace, people pay more and more attention to physical health and physical exercise. Among many ways of fitness, the exercise of leg muscles is particularly important, because it not only relates to sports performance, but also directly affects the stability and safety of daily activities. As a common way of leg exercise, leg training can effectively enhance the strength and endurance of thigh muscles, calf muscles and hip muscles.

[0003] After searching, the patent document with the publication number CN112190877A provides a self-weight type inclined up-pedaling training device. The device makes the force exerted by the user during exercise change. In the initial state, a smaller force is exerted on the device to lift the user up, the angle of the device increases, and the force gradually increases. When the user's leg is fully stretched, the force reaches the maximum. Then, when doing the recovery action, the force gradually decreases until returning to the starting position. In this way, it not only avoids damage to the knee, but also enables the user to fully exercise.

[0004] The above-mentioned device adjusting frame can be inserted into the fixed frame through the bolt to adjust the installation height of the pedal. This adjusting method is relatively complex on the one hand, and on the other hand, it cannot adjust the distance between the pedal and the seat, and cannot be applied to users with different heights. In view of this, we propose a leg training device convenient to adjust. CONTENT OF THE INVENTION
