Cardiovascular endurance is

Cardiovascular endurance consists of maintaining an increased heart rate and breathing rate for a longer period of time. Cardiovascular endurance can be accomplished through consistent exercise performed for prolonged periods of time. Cardiovascular exercise improves your body's ability to bring oxygen from the environment, into the lungs, and diffused into the bloodstream. With an increase flow of oxygen to cells in the body will help them work to their capacity. In addition, cardiovascular exercise helps the heart become bigger and stronger (it is a muscle), allowing more blood to be pumped out with each beat. If more blood is pumped out with each beat, the heart does not have to beat as fast or work as hard.
