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 Lifecycle recumbent bike features exclusive workouts designed to take full advantage of the
benefits of heart rate zone training exercise:
FAT BURN
,
CARDIO
,
HEART RATE HILL
(93R
only),
HEART RATE INTERVAL
(93R only),
EXTREME HEART RATE
(93R only). Each workout
offers different benefits, as discussed in Section 4, titled
The Workouts
.
During one of these workouts, wear the optional Polar heart rate chest strap to enable the bike’s 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 dur-
ing a workout, use the 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.
