Effective exercises for enhancing cardiovascular health include aerobic activities, such as running, cycling, swimming, and brisk walking. These exercises elevate the heart rate, improve circulation, and strengthen the heart muscle, making it more efficient at pumping blood. Consistent aerobic exercise can lower blood pressure, reduce cholesterol levels, and improve overall cardiovascular fitness. The American Heart Association recommends at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity aerobic activity per week for optimal heart health.
