Cardio

Short for "cardiovascular exercise," cardio refers to any exercise that increases the heart and breathing rate.

Typical examples include running, walking, cycling, and rowing. Cardio is usually contrasted with strength training exercises like push-ups, squats, and pull-ups. However, strength training and cardio need not be mutually exclusive — stringing together a series of resistance exercises with minimal rest can certainly meet the requirements of a cardiovascular workout[1][2].
