The Fat Burn and Cardio heart rate workouts adjust the resistance of the Lifecycle exercise bikes in response to
your heart rate. These two workouts use either the technology of the Lifepulse Digital Sensors (models C9i and
®
R9i) or Polar compatible telemetry (models C7i and R7i ) to monitor your heart rate and automatically adjust the
work load to maintain your Target Heart Rate. The end result is a perfect workout every time, eliminating both
under- and over-training.
On the Lifecycle exercise bike, the Fat Burn Workout will maintain your heart rate at 65% of your theoretical
†
maximum heart rate or another target heart rate that you enter. Pedal resistance will automatically adjust to
maintain the target heart rate. Exercising at 65% of your theoretical maximum heart rate maximizes the aerobic
benefits of exercise by accessing the body's fat stores for fuel and by allowing you to exercise longer.

The Cardio Workout is virtually identical to the Fat Burn Workout. The only difference is that your target heart rate is
calculated at 80% of your theoretical maximum to accentuate cardiovascular improvement by placing a heavier
workload on the heart muscle. If you wish to vary the focus of your exercise activities (once the warm-up is
complete), you may switch back and forth between the Fat Burn and Cardio Workouts at any time during a workout
by simply pressing the Enter Key- creating the ultimate interval training workout!
Remember, you may change your Target Heart Rate at any time after the warm-up period by simply pressing the
Up/Down Keys or toggling Fat Burn and Cardio target heart rates using the Enter Key.
The Life Fitness Heart Rate Zone Training workouts begin with a three-minute warm-up period designed to safely
get you closer to your target heart rate from a resting start. It should take two to three minutes for your heart rate to
reach your target.
NOTE: If your heart rate is above the chosen target during the warm-up period, the warm-up period will
immediately end and the Lifecycle exercise bike will begin automatically varying its resistance to maintain your
target heart rate.
