Research shows that exercising within a specific heart rate is the optimal way to monitor exer-
cise intensity and achieve maximum results. That is the idea behind the Life Fitness Heart Rate
Zone Training approach to exercise.
Zone Training Exercise takes the guesswork out of working out by identifying specific ranges, or
zones, in which to maintain a heart rate to achieve maximum exercise results according to
goals. In short, Zone Training Exercise all but eliminates under- and over-training by targeting
the heart rate to individual fitness objectives.
For instance, if the primary goal is to burn fat, exercise at a level between 60% and 75% of the
theoretical maximum heart rate
75% to 85% of the theoretical maximum heart rate.
Life Fitness offers two exclusive workouts designed to take full advantage of the benefits of
Heart Rate Zone Training Exercise: Fat Burn and Cardio (optional for CT 8500 in the U.S.A. and
Canada). The focus of the exercise activities can be varied by switching between the Fat Burn
and Cardio workouts at any time during a workout or by entering a new target heart rate with the
Up or Down Arrow keys or numeric keypad (CT 9500HR).
Both the Fat Burn and Cardio workouts measure heart rate. Wear the telemetry heart rate chest
strap and the heart rate will be transmitted to the on-board computer continuously. Alternately,
for CT 9500HR, grasp the Lifepulse sensors on the moving arms. The resistance level will auto-
matically adjust to maintain the target heart rate based on the actual heart rate.
