Regular aerobic activity positively influences heart health by strengthening the heart muscle, lowering resting heart rate, and improving overall circulation. Engaging in consistent aerobic exercises, such as walking, running, or cycling, helps reduce blood pressure and manages cholesterol levels. These activities also lower the risk of heart disease by fostering a healthy weight and improving blood vessel function. Furthermore, regular aerobic exercise promotes better oxygen supply to tissues, strengthening overall heart efficiency and contributing to a healthier cardiovascular system.
