[0002] The human body is an organic whole composed of various organ systems. When doing physical activities, it seems that only muscles are moving. In fact, the body's breathing, blood circulation and other organs are also participating in the activities, and they are all directed and coordinated by the cerebral cortex. Warming up is to increase the excitement of cortical nerve cells. Warming up can also slightly increase body temperature, so that muscles and tendons are in good condition, with good elasticity and stretchability, and will not be strained or torn due to sudden contraction. However, when users of existing leg sports training devices use them, they cannot use them when they are tall or short, which reduces the practicality of the device.
