1. I don't eat for nearly 10 hours at night, and my glycogen is basically exhausted in the morning. At this time, aerobic exercise can directly decompose fat to provide energy, thus achieving a very good fat-reducing effect. If it is aerobic training after meals, the body must first consume sugar to provide energy. Under the same exercise time, its fat-reducing effect is far lower than that of fasting aerobic training in the morning.

2. Aerobic exercise in the morning can keep the body's metabolism at a high level, and make the internal organs and other organs active, so that the body can burn fat even at rest. The effect of aerobic training at night is not good, and the metabolism of human body drops during sleep, reaching the lowest point of the day, which is not good for fat loss. For friends who gain muscle, on the contrary, after strength training at night, they go to sleep, and the reduction of human metabolism is conducive to energy conservation and muscle recovery.

3. Train the body to release endorphins in the morning. Endorphins can make people feel happy, reduce stress and enhance blood circulation. At the same time, morning exercises can make people full of energy and have a sense of accomplishment to overcome themselves.
