Sprint precautions:
Don't do warm-up exercises. Doing some simple physical exercises before physical exercise is conducive to safe and effective exercise. Because in the cold winter, due to the cold stimulation, the elasticity and ductility of muscles and ligaments are obviously reduced, and the flexibility of the whole body joints is much worse than that in summer and autumn.
If you don't do warm-up exercise before exercise, it is easy to cause muscle ligament strain or joint sprain, which makes the exercise unable to proceed normally. If the running is less than 10 km, there is almost no need to replenish water during running.
If you run every day, the amount of running should be controlled properly. At first, girls suggested running 3-5 kilometers, while boys suggested running 5- 10 kilometers. Don't run too much at a time, keep it like this for 1-2 months, and then gradually increase the amount. You must keep your balance and posture when running. Try to run during the day, not for fun. I know the road conditions during the day. brief introduction
