Whether you are overweight or trim, have hypertension or normal blood pressure, engaging in regular exercise such as walking, cycling, jogging or swimming can help lower your blood pressure and your subsequent risk of heart attack and stroke.
The review of 54 clinical trials involving 2,419 previously sedentary adults concluded that regular exercise decreased systolic blood pressure — the upper number in a blood-pressure reading — by an average of 4 mm of mercury (mm Hg) and diastolic blood pressure, the bottom number, by an average of 2.6 mm Hg.
Even a small reduction in the overall population's average blood pressure level should dramatically reduce the morbidity and mortality of heart disease and stroke in the US general population.
The new findings offer more evidence that exercise is important both for treating high blood pressure and preventing the condition from developing in healthy people, he said.
In addition to the cardiovascular risks, high blood pressure also can damage the kidneys, eyes and brain. Blood pressure is considered elevated if the reading is 140/90 or higher.
Statistics show that about 25% of US adults have high blood pressure and up to 30% are sedentary. While the study did not identify an ideal amount of exercise for lowering blood pressure, results showed that a variety of types of aerobic exercise at all frequencies were beneficial to people who were previously sedentary. In other words, some activity was better than none.
US health officials advise that people aim to get at least 30 minutes of moderate exercise on 5 or more days a week.

The heart and circulatory system
The heart beats faster to pump blood around the body more quickly to supply enough oxygen to the muscles to allow them to do work. At rest the heart normally pumps about 4 litres of blood per minute, but during moderate aerobic activities such as cycling, approximately 20 litres of blood per minute circulate throughout the body. The heart itself is a muscle and when exercised as in cycling it gets bigger and stronger just as your biceps do.
People who take part in regular physical activity have a lowered risk of cardiovascular disease compared with those who don’t.
Blood pressure
Regular aerobic activity such as cycling can prevent or delay the development of high blood pressure and in people who already have high blood pressure it can reduce blood pressure.

Cycling like any repetitive activity is considered cardio. It is way to complex to break down too far. Basically by exercising you are training your body to use what it has and to build what it doesn't. You will increase your vasculature and decrease the hearts need to beat like heck to get the oxygen to those starving cells.

Your heart is a muscle. Work it regularly and it will pump less to do the same amount of blood flow. Do not work it and you will have problems moving around yourself.
