It's not often you see straight cardio workouts on FitDaily that's not performed in intervals or based on specific exercise component. This one is here for sheer endurance and to show there's still value in regular cardio.
When doing straight cardio, monitor your heart rate and try to vary your pace throughout, but make sure you keep your pace well into your aerobic zone the entire time. There should be no reading books or being overly distracted on the treadmill. Concentrate on your pace and your heartrate. If you really need a distraction I suggest music or audiobooks.
