Official Body-for-LIFE Cardio-Training Plan Cardio workouts are indispensable to an effective training program and general good health. By definition, cardio workouts can be any exercise—jogging, running, biking, swimming, elliptical machine, stairs, even jumping rope—that raises and maintains your heart rate over a predetermined amount of time. By doing so, you strengthen your heart and lungs and lower your resting heart rate, which means that over time the same effort that produced a 10-minute mile will produce a 9-minute mile. Cardio workouts burn fat. And cardio fitness is what gives you endurance and the ability to persist in sports and in life. The Benefits of Cardio
