Aerobic exercise enhances lung function, strengthens the heart muscle, and stimulates healthy blood flow and circulation.
Aerobic exercise is any physical activity that causes your body to receive more oxygen as the word "aerobic" implies "with oxygen."
Your muscles need more oxygen to contract for an extended period of time while you workout.
Cells engage in cellular respiration during aerobic activity, which involves the conversion of oxygen and other molecules into adenosine triphosphate (ATP),
Your heart rate will increase as a result of the need to circulate more blood bringing oxygen to your muscles.
In order to boost the amount of oxygen in your circulation and body, your breathing rate will also rise.
