Why is cardio training so important?
Cardio training is exercise with the purpose of developing cardiovascular or aerobic fitness. Cardiovascular fitness is a good measure of the heart’s ability to pump oxygen-rich blood to the muscles.
Cardio training generally involves exercising at a constant moderate level of intensity, for a specified duration, during which the cardiovascular system is allowed to replenish oxygen to working muscles and rowing.
