Cardio workouts, short for cardiovascular workouts, are exercises that increase your heart rate and improve blood circulation. These activities can include running, cycling, swimming, and dancing. The primary goal of cardio is to enhance the efficiency of your heart and lungs, promoting overall health and fitness. Engaging in regular cardio workouts can help with weight management, boost energy levels, and reduce the risk of chronic diseases such as heart disease and diabetes. It's recommended to aim for at least 150 minutes of moderate-intensity cardio each week for optimal health benefits.
