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. The Life Fitness exercise bike features five exclusive
workouts designed to take full advantage of the benefits of Heart Rate Zone Training+ exercise: FAT BURN,
CARDIO, HEART RATE HILL
TM
, HEART RATE INTERVAL
TM
, and EXTREME HEART RATE
TM
. Each workout
offers different benefits, as discussed in Section 4, titled The Workouts.
NOTE: Consulting a fitness trainer is recommended for defining specific fitness goals and designing a workout
program.
All Zone Training workouts measure heart rate. Grasp the Lifepulse
®
Sensors (C9i), or wear the telemetry chest
strap (C7i) to enable the bike’s on-board computer to monitor the heart rate during a workout. The computer
automatically adjusts the intensity level to maintain the target heart rate* based on the actual heart rate.
* Target Heart Rate (THR) is a percentage of the theoretical maximum. For example, a 40-year-old user's recommended THR for the
HEART RATE INTERVAL workout is 144. The HEART RATE INTERVAL workout targets 80 percent of the maximum, so the equation
would be (220-40)*.80=144.
