Cardiovascular training, often referred to as cardio, involves exercises that increase your heart rate and improve the efficiency of your heart and lungs. Common forms of cardio include activities like running, cycling, and swimming. This type of training helps enhance overall fitness, endurance, and stamina. Engaging in regular cardiovascular training can lead to numerous health benefits, such as improved circulation, reduced risk of heart disease, and better weight management. It is recommended to include at least 150 minutes of moderate-intensity cardio each week for optimal health benefits.
