The typical beginner´s “Enough! Can´t do it anymore” has little to do with legs, because in fact we run with our heart. And this video will explain you why.
A human body has a cardiovascular system, that conveys blood through vessels and delivers nutrients and oxygen to all its parts and tissues, carrying away what cells do not need any more: carbon dioxide (CO2) and other wastes.
Blood can be compared to trucks at a construction site: they bring building materials and remove construction waste. Heavy breathing in new runners is caused by the lack of oxygen in the muscles.

So, let´s go by parts and start with learning a couple of general facts about our heart.
