"Exercise
Prolonged aerobic exercise may also increase stroke volume, which frequently results in a slower heart rate. Reduced heart rate prolongs ventricular diastole (filling), increasing end-diastolic volume, and ultimately allowing more blood to be ejected."

Stroke volume is the amount of blood that the heart can push out with each beat. It depends on three things: the amount of blood that comes into the heart, how hard the heart has to fight to push the blood back out to the body, and how hard the heart can contract.
Anaerobic exercise or lifting weights wouldn't have very much effect on it. However, regular aerobic activity helps to lower the blood pressure, which decreases how hard the heart must beat to get all the blood out. It also strengthens the heart and allows it to pulse more strongly with each beat. With both of these factors combined, aerobic activity directly leads to an increased stroke volume. This is a very good thing.
