Aerobic exercise performed at low intensity. Many people believe that this types of activity is a quick way to become lean because it uses a higher percentage of fat for energy when compared with a high-intensity activity. However, the total energy expenditure for a given period of time is much less for the low-intensity activity, and the actual amount of fat lost may be the same for both types of activity. Nevertheless, low-intensity aerobics does have the advantage of being less stressful on the joints and, although it may not contribute greatly to aerobic fitness, it probably does provide a sufficient stimulus to the heart to reduce the risk of cardiovascular diseases.
