3 HEART RATE ZONE TRAINING EXERCISE
3.1 WHY 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 increasing cardiovascular fit-
ness. The zone is a percentage of the theoretical maximum
†
(HRmax), and its value depends on the workout. The Life
Fitness Cross-Trainer features five exclusive workouts designed to take full advantage of the benefits of Heart Rate
Zone Training exercise:
• FAT BURN • HEART RATE HILL • EXTREME HEART RATE
• CARDIO • HEART RATE INTERVAL
Each workout offers different benefits, as discussed in Section 4, The Workouts.
NOTE: Consulting a fitness trainer is recommended for defining specific fitness goals and designing a workout program.
The Heart Rate Zone Training workout programs measure heart rate. Wear the optional telemetry chest strap, or grip the
Lifepulse sensors, to enable the cross-trainer’s on-board computer to monitor the heart rate during a workout. The com-
puter 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, simply enter a new target heart rate by typing in the desired number
on the numeric keypad or by pressing the Heart Rate button on the Touchscreen.
To switch between programs during a workout, use the CHANGE WORKOUT
button.

Defined by the American College of Sports Medicine's "Guidelines for Exercise Testing and Prescription" as equal to 220 minus an individual’s age.
* Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a 40-year-old user's THR for the FAT BURN workout is 117. This workout targets 65 per-
cent of the maximum, so the equation would be (220-40)*.65=117.
