Popular forms of aerobic exercise include jogging, brisk walking, swimming, biking, cross country skiing, and aerobic dancing. Aerobic exercise uses the body's large muscle groups in a continuous, rhythmic and sustained movement and requires using oxygen for the production of energy.

When oxygen is combined with food (the stored fat in your body's cells) energy is produced. The longer that you move aerobically, the more energy is needed and the more calories are used.

Regular aerobic exercise will improve your cardio-respiratory endurance. This is the ability of your heart, lungs and blood vessels to produce energy. Plus you will also build up your muscular endurance.

When you engage in a regular program of exercise you will build a healthier body and you will lose excess body fat because you will be using up the stored fat in your body cells.

Never begin an exercise program until you have consulted with your doctor about what kinds of exercise will be beneficial for you, and once you begin, maintain your exercise program.

A good recommendation is some form of aerobic exercise at least three times a week for a minimum of 20 continuous minutes. If that is too much, simply start with a shorter time span and build up to that level. If you need to lose a large amount of weight, you will want to build up to a 30 minute workout five times a week or even daily.
