: A proper warm-up is essential before the official run. Just like the car needs to be warmed up before starting, the body needs to warm up to increase the metabolism and raise the temperature to prepare for the upcoming exercise. For example, dynamic stretching, moving wrists and ankles, lunges, leg lifts and other actions can effectively move joints and muscles to prevent injuries. In many of the competition videos, the pros will carefully warm up, which is the basis for a successful finish.
