Aerobic exercise is any physical activity that gets your heart rate up and increases your breathing rate. This includes activities like running, cycling, swimming, and dancing. Aerobic exercise is important for cardiovascular health, as it strengthens the heart and lungs and improves circulation. It also burns calories, helps with weight loss, and reduces the risk of chronic diseases like diabetes and heart disease. Regular aerobic exercise can improve mood, boost energy levels, and enhance overall well-being.
