Exercise benefits cardiovascular health by strengthening the heart muscle, improving circulation, and reducing blood pressure. Regular physical activity helps maintain a healthy weight, which is essential for heart health. It can also enhance cholesterol levels by elevating the amount of high-density lipoprotein (HDL), which protects against heart disease. Furthermore, exercise encourages better blood sugar control and reduces the risk of type 2 diabetes, indirectly benefiting cardiovascular health. Engaging in aerobic activities, like running or cycling, can lead to significant improvements in heart function and overall endurance.
