Lack of exercise is a risk factor for developing
coronary artery disease (CAD). Lack of physical activity can indirectly increase the risk of
CAD, because it also increases the risk for

Regular exercise is essential not only for preventing CAD
but also for improving your overall heart health.
It also is possible that regular physical activity increases the
number of smaller blood vessels that connect different coronary arteries. If
one of the major coronary arteries is suddenly blocked, these collateral blood
vessels serve as an alternate route to supply blood to the portion of the heart
muscle threatened by a heart attack.
