Generally speaking, as long as the sun comes out in the morning, the time before 9 pm is optional (not after meals). However, the best time to lose weight by exercise depends on the type of exercise and your usual living habits. For the normal office workers of the Student Party, the exercise time is only twice: before breakfast in the morning and after dinner in the evening.
In addition, from the point of view of preventing sports injuries, it is best to exercise in the afternoon or evening, because the body temperature in the afternoon is higher than that in the morning, muscles and joints are more flexible, and various physical indexes of people reach the peak.
