Aerobics exercise is a vigorous exercise designed to increase cardiovascular efficiency. Aerobic exercise is any physical activity that makes you sweat, causes you to breathe harder and gets your heart beating faster than at rest. It strengthens your heart and lungs and trains your cardiovascular system to manage and deliver oxygen more quickly and efficiently throughout your body. Aerobic exercise uses your large muscle groups, is rhythmic in nature and can be maintained continuously for at least 10 minutes. In addition to strengthening your heart and cardiovascular system, participation in regular aerobic exercise has many health benefits.
