Cardiovascular workouts, often referred to as cardio, are exercises that elevate your heart rate and improve the efficiency of your heart and lungs. Common forms of cardio include activities like running, cycling, swimming, and jumping rope. These workouts help increase endurance, burn calories, and enhance overall fitness. Engaging in regular cardiovascular exercise can lead to numerous health benefits, such as reduced risk of heart disease, improved mood, and better weight management. It is generally recommended to aim for at least 150 minutes of moderate-intensity cardio each week to maintain optimal health and fitness levels.
