HEART RATE WORKOUTS
Research shows that maintaining a specifi c heart rate while exercising is the optimal way to monitor the intensity of a
workout and to achieve maximum results. That is the idea behind the Life Fitness Heart Rate Zone Training approach to
exercise. Zone Training identifi es an exerciser’s ideal heart rate range, or zone, for burning fat or increasing cardiovas-
cular fi tness. The zone is a percentage of the theoretical maximum (HRmax), and its value depends on the workout. The
maximal heart rate formula is defi ned by the American College of Sports Medicine’s
Guidelines for Exercise Testing and
Prescription
, 8th Edition, 2010. HRmax equals to 206.9 minus the total of 0.67 multiplied by a person’s age.
Theoretical Maximum Heart Rates and Target Heart Rates
Reference the chart below for Theoretical Maximum Heart Rates and Target Heart Rates.
Wear the optional Polar
®
telemetry heart rate chest strap, or grip the Lifepulse
TM
sensors, to enable the on-board com-
puter to monitor the heart rate during a workout. The computer automatically adjusts the incline level to maintain the
target heart rate based on the actual heart rate.
The Polar
®
Telemetry Heart Rate Chest Strap
The Polar telemetry heart rate monitoring system transfers heart rate signals to the console when electrodes are
pressed against the skin. These electrodes are attached to a Polar telemetry heart rate chest strap that the user wears
during the workout. The Polar telemetry heart rate chest strap is optional. Contact Life Fitness Customer Support Ser-
vices to order.
See the diagram to the right of this paragraph for correct positioning of the Polar telemetry heart rate chest strap. The
electrodes (A), which are the two grooved surfaces on the underside of the strap, must remain wet to transmit accu-
rately the electrical impulses of the heart back to the receiver. Moisten the electrodes. Then, secure the Polar telemetry
heart rate chest strap as high under the chest muscles as possible. The
strap should be snug, but comfortable enough to allow for normal breath-
ing.
The transmitter strap delivers an optimal heart rate reading when the elec-
trodes are in direct contact with bare skin. However, it functions properly
through a thin layer of wet clothing. If it becomes necessary to re-moisten
the Polar telemetry heart rate chest strap electrodes, grasp the center of
the strap, pull it away from the chest to expose the two electrodes, and re-
moisten them.
Note:
If the Lifepulse system sensors are grasped while the chest strap is worn, and if the signals from the sensors are
valid, the on-board computer uses these sensor signals for calculating the heart rate instead of those transmitted by the
Polar telemetry heart rate chest strap.
