For physical exercise, it is better to exercise from 3 pm to 9 pm in a day. Because after a day's work activities, the blood circulation is improved and accelerated, the muscle viscosity is reduced, the tension is increased, the excitability is increased, and the range of joint activity is large.

1. This period is the peak of physical strength, full of energy and enhanced sports ability, which is really a good time for fitness exercise. Studies have proved that the central nervous system of human movement is the most active from 3 pm to 9 pm, and the excitability is stronger than inhibition. During this period, many world records were broken.

Exercise in the morning, so the time requirement is strict. Because after a day and a night's sleep, the human body has no food and no activity. In the morning, the body is dry, the muscles are sticky, the body is inert, the blood viscosity is high, and the blood circulation is slow, so it is not easy to mobilize the enthusiasm of muscle activities.

3. If time permits, it's best to exercise at the same time every day, which can stimulate the desire to exercise, improve the exercise ability and achieve the best exercise effect.
