2, exercise methods should be appropriate, winter fitness should improve the intensity and intensity of exercise, increase the number and frequency of movements, at the same time increase the content of aerobic exercise, and correspondingly extend the exercise time to improve the function, develop special qualities, consume body fat and prevent excessive accumulation of fat. In addition, pay attention to the exercise interval should be shorter, especially when standing in cold air for a long time outdoors. If the interval time is too long, the body temperature will drop, which will easily make the muscles tired from the excited state and increase the viscosity, which will not only affect the exercise effect, but also easily hurt when the next group of exercises is carried out.
3. Warm-up activities should be sufficient. When exercising in winter, especially outdoors, you should first do a good job of warm-up activities. After jogging, unarmed exercise and a small amount of light equipment practice, you will get hot and sweat a little, and then join in fitness activities. If you exercise without doing warm-up activities, it will often cause muscle strain and joint sprain.
4, the thickness of clothing should be appropriate, exercise in winter, start to wear more clothes, wear clothes to be soft, not too tight, and take off some thick clothes after warming up. After exercise, if you sweat a lot, you should dry the sweat in time, change into sweaty sports clothes, shoes and socks, and wear a hat at the same time to prevent heat loss. In addition, you should pay more attention to keep warm when you are exercising outdoors. After exercise, you will have more fever and always want to cool off, but you must not stand in a windy place to blow. Instead, you should return indoors as soon as possible, dry your sweat and put on clean clothes. As the saying goes, "Cold comes from the foot." Because people's feet are far away from the heart, the blood supply is less, and the subcutaneous fat of the feet is thin, so the warmth retention is poor. Therefore, it is particularly easy to feel cold feet when exercising outdoors in winter. If the head, back and feet are cold, cold air will invade the body from fur, nose and mouth, which will not only affect the effect of fitness exercise, but also catch a cold and get sick. Usually, some fitness enthusiasts like to wear fitness shoes for winter, which is not good. Because rubber-soled shoes conduct heat quickly, the soles of your feet are easy to get cold when you don't exercise, which leads to chilblain, arthritis and other diseases.
