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
increasing cardiovascular fitness. The values within the zone depend on the workout.
NOTE: Consulting a fitness trainer is recommended for defining specific fitness goals and
designing a workout program.
The Life Fitness Total Body Trainer features exclusive workouts designed to take full advantage
of the benefits of heart rate zone training exercise: FAT BURN and CARDIO. For detailed infor-
mation about the workouts, see Section 4, titled The Workouts.
During one of these workouts, grasp the Lifepulse system sensors continuously, or wear the
Polar heart rate chest strap to enable the on-board computer to monitor the heart rate during a
®
workout. 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
LEVEL ARROW keys.
* 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.
