Aerobics is any system of conditioning exercises that increases heart and breathing rates for a sustained period and thus increases the flow of oxygen and blood to all parts of the body. To be effective, the exercise must raise the pulse rate to a certain level (see the following chart) and keep it at that level for not less than twenty minutes. (Note: People who are not in good physical condition should start out with ten minutes at the minimum heart rate and build to twenty minutes at the maximum heart rate.)

Aerobic conditioning benefits the body in many ways. It will decrease intramuscular fat and increase lean muscle, leading to a firmer, stronger body. Aerobic exercise improves circulation; a trained heart is a more efficient pump and therefore doesn’t have to work so hard. This lowered heart rate preserves the heart and lessens its chance of fatiguing prematurely. Aerobics improves absorption and utilization of food; provides overall increases in energy and stamina; encourages more restful sleep; and decreases dependence on addictive substances such as alcohol, drugs, and tobacco. Most exercisers report a decrease in nervous tension and depression. And it is now known that exercise causes the release of endorphins that increase an overall sense of wellbeing.

If you are not in the habit of exercising regularly, you may hear the word “aerobics,” and immediately see visions of thin, tight bodies in coordinated workout gear, or think with dread about running. Don’t be discouraged. A wellness approach to exercise is not that limited.
