My opinion is: Exercise for health? Or sports medicine? Health is about 6Km a day, and the treatment is definitely many times that of ordinary people. People who cherish their strength, then don't say anything! Step by step-standard exercise is an excellent exercise, which can take 1000 steps at any age. The best rehabilitation method is safe, effective, simple, economical and has few complications.
Because I have been "empathetic" for many years, many diseases are recovered by exercising on the treadmill.
