You can do sports when you are free. You don't need to specify a certain time period. But you can't do it after dinner.

Just after eating, the appropriate exercise is walking, just walking in the community, but you can't do strenuous exercise, which will be counterproductive.

Theoretically, this is a good night, because as far as people's physical condition is concerned, people are in a state of water shortage after a night's sleep, and their blood is sticky in the morning, and then strenuous exercise may cause dangers such as insufficient blood supply to the brain, cerebral hemorrhage and myocardial infarction. If you like morning exercises, I suggest you drink 1-2 cups of boiled water after washing, and then exercise. From the environmental point of view, some toxic gases in the air are difficult to volatilize before the sun comes out, which is not suitable for exercise. From the follow-up reaction, it is easy to eat more after exercise in the morning, but it increases the intake.

Exercise after meals is mainly to burn excess calories in the body. However, it is not appropriate to exercise immediately after meals. At this time, the blood is concentrated in the stomach for digestion, and immediate activities affect digestion. It is advisable to go out for activities half an hour after supper. The most ideal way to exercise is brisk walking, which lasts for more than half an hour, so that the fat cells in the whole body can exercise fully. Aerobic breathing can oxidize the fat in the body, so aerobic exercise can lose weight. Running hard, out of breath, the body is in a certain degree of hypoxia, and it is impossible to oxidize fat.
