Aerobic dancing

There's nothing mysterious about aerobic exercise. It simply refers to the kind and level of physical effort that increases the body's consumption of oxygen. In fact, aerobic means "needing oxygen in order to live".

When we exercise enough to need more oxygen, our heart and lungs are forced to work harder to provide it. When they work harder, a host of good things happen. The heart is conditioned to beat more strongly. As a result, it pumps more oxygenated blood to all our tissues, nourishing them better. Though we gain a faster heart rate during the exercise, the heart returns to its resting state quickly. In other words, it works much more efficiently. (These benefits translate into more protection against heart attacks.) Our capacity to take in oxygen and discharge carbon dioxide also improves; our lungs become better conditioned. As we gain in physical fitness, we become able to engage in more strenuous activity over a greater length of time with less fatigue.

There's confusion in some people's minds about what constitutes an aerobic exercise and what does not. Jogging is definitely aerobic. So are swimming, brisk walking and bicycling, as well as aerobic dancing. Tennis is not always an aerobic exercise because it isn't continuous. In order for an activity to qualify as aerobic, it has to be somewhat vigorous and sustained, maybe 15 minutes or a half hour, at least 3 or 4 times a week. Improvement in fitness comes over time, not overnight.
