Let's just say that reasonable and moderate exercise is good for your health. Some exercises are good for tonifying the kidney, such as "lying in the sun", but fitness is mostly strength-oriented exercise, which is not suitable for people who are weak or prone to sweating. Excessive fitness is not helpful to the body, but harmful to the body. From a physical point of view, most fitness is not suitable. Exercise, the best time is in the morning, not suitable for strenuous exercise at night. In a beautiful outdoor environment, it is good for people who are weak or easy to sweat to walk quickly. If you are healthy, you can jog moderately and sweat best.
