If it's to lose weight and increase the memory of motor skills, morning is good. When people wake up in the morning, they have consumed almost all the energy they ate last night. At this time, not eating and not exercising will lead to a result-"burning" fat. There is still some glycogen in the liver because there is no energy in the morning. When the concentration of these glycogen is reduced to a certain extent, fat "burning" will become the dominant way of energy supply, thus making it possible to lose weight. Therefore, exercise in the morning has special benefits for losing weight and preventing fatty liver. Besides, it is easier for people to learn aerobics, ballroom dancing and Tai Ji Chuan in the morning than at other times. Therefore, the health benefits of morning exercises are more in a sense.

The ancients paid attention to "smelling chickens and dancing", and fitness was generally chosen in the morning. As for the carbon dioxide in the air in the morning, the serious pollution is not the main reason. In fact, the pollution of automobile exhaust during the day is also very serious, which will release lead, heavy metals and some chemical wastes, such as benzene. Blood pressure is high in the morning and can be adjusted by drugs. Therefore, when is the best time to exercise is not absolute. It also varies from person to person.

Whether in the morning or afternoon, you should exercise moderately. As far as health is concerned, it is effective to start exercising at any age. Exercise more when you have time, but exercise less when you have no time. Just move, even if it's just a trick.
