Aerobics practice can be arranged in the morning, day or night according to one's work, study and living habits. Among them, 3 pm to 8 pm is the best time, because physical strength is relatively strong during this time, and exercise after work can also play a role in eliminating fatigue. 2-3 times a week, each time 1-2 hours. If you practice before meals, rest for half an hour before meals and rest for more than 1 hour after meals. Practice at night, two hours before going to bed, so as to avoid excessive excitement and falling asleep.

Second, pay attention to sports hygiene.

Warm-up activities should be carried out before doing aerobics to warm the body and improve the excitement of the nervous system. Because the human body needs to overcome the physiological inertia of internal organs from a quiet state to a moving state, and the beginning of movement should be gradually strengthened, so that blood circulation and gas exchange can be gradually improved; Metabolism can gradually flourish, making joints, muscles and ligaments more flexible and flexible, which can not only prevent injuries, but also prepare the body for functions. After the exercise, you should do finishing activities, so that the blood flowing into the muscles can slowly flow back to the heart during the exercise, the body will gradually return to a calm state, and the tense muscles will be stretched and relaxed. Taking a hot bath after exercise can make the whole body feel comfortable, refreshed and more energetic.
