You don’t have to walk far and you don’t have to walk fast, but you really should walk. According to a study at Lawrence Berkeley National Laboratory, you can get the same health benefits walking as you can by running. The calories burned by both walking and running were equally effective when it came to the health benefits to the cardiovascular system.
