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.
