The air in the morning is the most turbid, the cells in the body are still resting, and the blood pressure is low. You shouldn't do a lot of exercise. You should walk in the morning to exercise your bones and muscles.

The air is the best in the morning, especially at 8: 00 or 9: 00, when plants start photosynthesis, they will release a lot of oxygen, so it is better to do some aerobic exercise in the morning.
