How Does Cardio Exercise Affect Your Heart?

When performing cardiovascular exercises, blood flow is directed toward working muscles and away from areas that aren't doing much (such as your arms during running, or the digestive tract). There is increased blood flow, and blood volume returning to the heart.

As the heart registers a larger blood volume, over time the left ventricle adapts and enlarges. This larger cavity can hold more blood, and ejects more blood per beat, even at rest.

Over time, with chronic cardio training, our resting heart rate drops because each beat delivers a bigger burst of blood, and fewer beats are needed. This takes work off your heart and is why cardio exercise is recommended for heart health.

Note: Consulting a doctor before beginning any exercise program is recommended, especially for individuals with heart conditions or cardiovascular issues.
