Lets do some cardio!!!

As we do exercise our heart becomes more effective. This is because our heart is a muscle and as any other muscle if you exercise it, the muscle increase in size. When this happen our heart becomes able to pump more blood to our body with less pressure and more effectiveness giving us the ability to supply more oxygen for those muscles that need it in order to produce energy and perform the physical activity. That is why do cardio is  important as it will allow us to supply more oxygen for better production of energy and remove of carbon dioxide which only makes us feel our muscles tired.
