Because the seat of a bicycle can't fully support its own weight during exercise, it can exercise more than running. Riding a bike seems simple, but it is actually exercising the muscles of the whole body. When pedaling, you can exercise quadriceps femoris on the thigh surface and gluteus maximus on the hip; The force transmitted by the pedal can exercise the triceps surae; Holding the handle with both hands can exercise the back muscles and abdomen, as well as the upper wrist triceps and upper body muscles of both hands.
