Commonly recommended exercises to improve cardiovascular health include activities such as running, cycling, swimming, and brisk walking. These aerobic exercises elevate the heart rate and enhance lung capacity while promoting overall endurance. Engaging in moderate to vigorous intensity workouts for at least 150 minutes per week is vital for reaping cardiovascular benefits. Incorporating interval training—alternating high and low intensity—can further improve cardiovascular fitness. It's also essential to ensure that these exercises are enjoyable and sustainable to maintain long-term participation.
