Aerobic exercise, also known as cardio or endurance activity, is the cornerstone of most fitness training programs. Aerobic exercise causes you to breathe faster and more deeply, which maximizes the amount of oxygen in your blood. The better your aerobic fitness, the more efficiently your heart, lungs and blood vessels transport oxygen throughout your body — and the easier it is to complete routine physical tasks and rise to unexpected challenges, such as running to your car in the pouring rain.
Aerobic exercise includes any physical activity that uses large muscle groups and increases your heart rate. Try walking, jogging, biking, swimming, dancing, water aerobics — even leaf raking, snow shoveling and vacuuming.
For most healthy adults, the Department of Health and Human Services recommends that you get at least 150 minutes a week of moderate aerobic activity or 75 minutes a week of vigorous aerobic activity. You also can do a combination of moderate and vigorous activity. The guidelines suggest that you spread out this exercise during the course of a week.
