Walking: The Slower, Surer Way to Fitness
People walk for many reasons: for pleasure...to rid themselves of tensions...to find solitude...or to get from one place to another. Nearly everyone who walks regularly does so at least in part because of a conviction that it is good exercise.
Often dismissed in the past as being "too easy" to be taken seriously, walking recently has gained new respect as a means of improving physical fitness. Studies show that, when done briskly on a regular schedule, it can improve the body's ability to consume oxygen during exertion, lower the resting heart rate, reduce blood pressure, and increase the efficiency of the heart and lungs. It also helps burn excess calories.
