How do you tap your inner aerobic self? It is simple. By using the strongest muscles in your body - the muscles of your legs. When you move your legmuscles vigorously, continuously, steadily for 20 to 42 minutes, four to six times a week, they push your cardiovascular system (heart, lungs and circulatory system) into working at a rate that demands large amounts of oxygen. And since our entire body-brain system is built to work on the principle of oxygen-inhalation, it brings about dramatic, miraculous changes within us.
