Running burns more calories in less time than almost any other continuous exercise.
A regular running or walking program lowers your risk of life-threatening maladies such as heart disease, high blood pressure, and diabetes.
Walking is a low-impact exercise that produces less stress on the knees and joints than many other activities do.
Both walking and running produce endorphins, brain chemicals that make you feel happy and confident.
Both are social activities—you can run or walk with a friend, your kids, or even strangers in a race.
