In winter, the climate is dry and the temperature drops, but people's enthusiasm for participating in outdoor fitness has not decreased at all. In winter, what should exercisers who like sports pay attention to in order to achieve healthy goals? First, keep warm to prevent colds. Because I come out to exercise in winter, I often wear less clothes for the convenience of activities, and I am prone to catch cold on the way to the sports place. So you'd better put on your coat and take it off at the beginning of the activity. And just after exercise, because the blood circulation is very fast, the body is rapidly dissipating heat, and I can't feel cold in a short time. But at this time, the pores are open, and cold air can easily stimulate the body, causing hidden harm. So put on your coat in time after exercise and keep warm. Second, make full preparations. Cold weather, vasoconstriction, poor blood circulation and tight muscles and ligaments can easily lead to muscle strain, ligament tear and even fracture. So warm-up activities must be done well, not only before strenuous activities, but also when walking and jogging. Third, when the temperature is very low in winter, it is best to avoid direct contact with the skin when using fitness equipment outdoors. You'd better wear gloves when using metal instruments. Considering friction, it is best to wear leather gloves or rubber-soled shoes when making parallel bars or pedals to avoid slipping.
