Aerobic exercise (also known as cardio) is physical exercise of relatively low intensity that depends primarily on the aerobic energy-generating process. Aerobic literally means "living in air", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism. Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time.

Famous quotes containing the word exercise:
“I have never taken any exercise, except sleeping and resting, and I never intend to take any. Exercise is loathsome. And it cannot be any benefit when you are tired; and I was always tired.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
