The concept of fitness is very broad and can be roughly divided into mechanical exercise and non-mechanical exercise. As Xiao Bai, it is impractical and unsafe to use difficult equipment from the beginning. So, step by step, starting from the foundation. Xiaobai can choose jumping rope, jogging and other sports with lower difficulty coefficient to enhance endurance. Wait until the physical fitness and athletic ability reach a certain height, and then increase the difficulty.

Secondly, in the process of exercise, one thing is often easy to forget, and that is warm-up. It seems unnecessary, but it can prevent us from being pulled by cramps during exercise and reduce the possibility of injury. Warm-up doesn't need high intensity, stretching or jogging for a while can have a good effect.
