Precautions:
1, Warm-up activities should be sufficient: Exercise without warm-up activities will often cause muscle strain and joint sprain. Therefore, when doing fitness exercises in winter, especially outdoor sports, we should first warm up. After jogging, unarmed exercise and a little light weapon exercise, we will warm up and sweat a little, and then we will devote ourselves to fitness.
2, breathing methods should pay attention to: do not open your mouth to breathe, so as not to directly stimulate the throat by cold air, causing upper respiratory tract infection and cough.
3. Winter fitness exercise consumes a lot of heat because of the low temperature, large heat dissipation, correspondingly increased basal metabolism and large amount of exercise. Therefore, it may be beneficial to friends who want to lose fat, and it is difficult to increase muscle strength, so pay more attention to scientific diet.
