Because the body is a circulatory system, when you exercise in one place, all the cells in your body will be active, just like walking at an accelerated pace, so will your legs. The more you exercise, the more powerful you will be. Legs play a very important role. When you exercise your legs, your blood will quickly become active and stimulate every nerve to improve your metabolism, because your legs are also the strength. Not only do you walk on your legs, but the more you exercise your legs, the better. At the same time, it also has a certain protective effect on your leg bones. For example, exercising your legs will help you get shorter.
