Cardio

My favourite hobby

Aerobic exercise (also known as endurance activities,[1] cardio or cardio-respiratory exercise) is physical exercise[2] of low to high intensity that depends primarily on the aerobic energy-generating process.[3] "Aerobic" is defined as "relating to, involving, or requiring oxygen",[4] and refers to the use of oxygen to meet energy demands during exercise via aerobic metabolism adequately.[5] Aerobic exercise is performed by repeating sequences of light-to-moderate intensity activities for extended periods of time.[3] Examples of cardiovascular or aerobic exercise are medium- to long-distance running or jogging, swimming, cycling, stair climbing and walking.
