Aerobic exercises are workouts done with the utilization of oxygen to improve the conditions of the heart, lungs and blood vessels. It usually involves the large muscles of the legs, back and chest and is done at moderate intensity for a longer period of time so that carbohydrate is turned into energy. When the carbohydrate stores in the form of glycogen in the liver and muscles have become depleted, the body will metabolize fat to fuel the activity. Since this is a slow process, the individual exercising will feel fatigue and energy loss unless the person gets a little rest or guzzles up energy drinks to maintain the energy levels.

Because this kind of workout improves the oxygen-carrying capacity of your heart and lungs, it is highly beneficial for health. However, for aerobic exercises to achieve their desired effects, they must be performed for at least twenty minutes a day for a minimum of three times a week. Examples of workouts that develop your cardiovascular system are swimming, bicycling, running, dancing, jogging, power walking and climbing the stairs.

One of the best health benefits that can be derived from adhering to an aerobic regimen is reducing your risk of dying prematurely from cardiovascular disease. As air is taken in and expended out of the lungs, the muscles involved in respiration are strengthened and developed. Together with this, the heart muscle is also enlarged and fortified, improving its efficiency in pumping blood in and out of the system. When the heart and lungs are enhanced and circulation is improved, blood pressure gets reduced and more red blood cells in the body facilitate the transport of oxygen throughout the tissues.
