The best type of exercise for cardiovascular health improvement is aerobic exercise. Activities like running, cycling, swimming, and even brisk walking elevate heart rate and improve blood flow. Regular aerobic exercise strengthens the heart, lowers blood pressure, and increases lung capacity. Incorporating moderate to vigorous intensity aerobic sessions for at least 150 minutes weekly can enhance cardiovascular endurance and overall fitness. Additionally, pairing aerobic workouts with strength training can provide comprehensive benefits, supporting muscle health and metabolic function.
