Cardio exercises increase your blood circulation and overall heart rate. Performing cardio exercise is an ideal method of losing fat, improving physical endurance, and maintaining good health. It is also associated with numerous health benefits such as a decreased risk of chronic diseases like cancer, diabetes and heart disease. One of the most essential benefits of cardio is fat loss. Cardio workouts burn as much as 67 percent more calories than strength training exercise. Cardio also improves your lung capacity, reduces stress, and enhances sleep quality.
