The right time to exercise:

The prime time for exercise in a day is 16: 00- 17: 00 in the afternoon, because after a whole day's daily work, the muscles and ligaments of the human body have been fully active, and the heart rate and blood pressure tend to be stable, so you can carry out more intense aerobic exercise, such as running, playing ball, swimming and equipment fitness.

If you are working, you can postpone your exercise until 17: 30- 18: 30. This time is afternoon and evening. The sun has not set yet, and it is still in season. At this time, exercise not only avoids working hours, but also does not affect the collection of the spirit of the sun after sunset, and there is no conflict with dinner time, which is more suitable for working people.
