Cardiovascular workouts, often referred to as cardio, are exercises that increase your heart rate and improve blood circulation. These activities include running, cycling, swimming, and dancing. Engaging in cardio helps strengthen the heart and lungs, enhancing overall fitness and endurance. Regular cardiovascular exercise can also aid in weight management and reduce the risk of chronic diseases such as heart disease and diabetes. It is recommended to perform at least 150 minutes of moderate-intensity cardio each week for optimal health benefits.
