Cardiovascular activities, also known as aerobic exercises, are physical activities that increase your heart rate and improve blood circulation. Examples include running, swimming, cycling, and dancing. These exercises help strengthen the heart and lungs, making them more efficient at delivering oxygen to the body. Engaging in cardiovascular activities can provide numerous health benefits, such as weight management, improved mood, and reduced risk of chronic diseases like heart disease and diabetes. It is generally recommended to perform at least 150 minutes of moderate-intensity aerobic exercise each week for optimal health.
