Aerobic exercise greatly benefits heart health by improving the efficiency of the cardiovascular system. It strengthens the heart muscle, enabling it to pump blood more effectively and reduce resting heart rate. Regular aerobic activity helps lower blood pressure and improve cholesterol levels, reducing the risk of heart disease and stroke. Additionally, aerobic exercise enhances circulation and may contribute to weight management, reducing strain on the heart. Engaging in activities like running, cycling, or swimming can lead to long-term cardiovascular health improvements.
