Cardio training increases the function, capacity, and health of the heart and lungs. There are basically two types of cardio training: aerobic and anaerobic.

Anaerobic training, which means without oxygen, is training that does not allow the exerciser to breathe in as much oxygen, limiting the amount of oxygen to the muscles requiring the body to gain energy from carbohydrates, a form of sugar in the body.
