Term used to refer to training or exercise which develops cardiovascular conditioning, by increasing heart rate (known also as aerobic exercise) and burning calories. Running, walking, swimming and team sports such as football or netball are all examples of ‘cardio’.

Some forms of cardio are moderate intensity, whereas other are vigorous, or high intensity.

Cardio activity is essential for heart and respiratory health. It is also thought to facilitate the release of endorphins and help mental well-being too.
