HY HEART RATE ZONE TRAINING EXERCISE?
Research shows that maintaining a specific 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 identifies an exerciser's ideal heart rate range, or zone, for burning fat or increas-
ing cardiovascular fitness. The values within the zone depend on the workout.
Note: Consulting a fitness trainer is recommended for defining specific fitness goals and design-
ing a workout program.
The Model 91Ti treadmill features exclusive workouts designed to take full advantage of the
benefits of heart rate zone training exercise: FAT BURN and CARDIO. Each workout offers
different benefits, as discussed in Section 4, titled The Workouts.
During one of these workouts, grasp the Lifepulse system sensors, or wear the Polar heart rate
chest strap to enable the on-board computer to monitor the heart rate. The computer automatically
adjusts the resistance level to maintain the target heart rate* based on the actual heart rate. To
change the target heart rate during a workout, use the SELECT ARROW keys.
Although the Model 90T does not offer the FAT BURN and CARDIO workouts, it is equipped
with Polar telemetry heart rate monitoring. The Polar heart rate chest strap is sold separately for
both the Model 91Ti and the Model 90T.

* Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a 40-year-old user's THR for the CARDIO
workout is 144. This workout targets 80 percent of the maximum, so the equation would be (220-40)*.80=144.
