Cardiovascular fitness

Cardiovascular fitness Exercise may be aerobic or anaerobic. Aerobic exercise requires oxygen to ensure that there is enough energy for exercise to continue. Anaerobic exercise is of short duration and depends on stored energy sources instead of oxygen. Aerobic exercise, such as running, swimming, or dancing, improves your cardiovascular system (your heart and blood vessels). Exercises for improving muscle strength and flexibility are examples of anaerobic exercise.
