Cardio
Cardio is exercise that raises your heart rate and breathing to work the heart and lungs.
Definition
Cardio, short for cardiovascular exercise, is any rhythmic activity that gets you breathing harder and keeps your heart rate up for a sustained period. Common examples include running, cycling, swimming and aerobics classes, where you keep moving continuously rather than in short bursts.
The term is used broadly in fitness to describe this kind of heart-and-lungs work, as opposed to strength exercises focused on lifting. Cardio can be steady and continuous, or built from intervals of harder and easier effort, and it scales from a gentle walk to a fast run.
