1, warm-up before running Speaking of long-distance running, the first thing you have to do is warm up before running. Track and field sports can easily cause injuries to muscles, joints and ligaments, especially lower limbs.

2. Relax after running. Don't stop immediately after running, then walk for three to five minutes until the whole body is relaxed, and do stretching exercises in time to open the ligaments of the body, and be sure to keep it for a certain time. Long-term persistence will be of great help to the improvement of physical fitness and is conducive to bodybuilding. Then do other training.
