Cardio workouts
		Cardio workouts are indispensable for 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.
