When prompted by the MESSAGE CENTER to enter age, use the ARROW KEYS to increase or
decrease the displayed age to the correct value, and press ENTER. Lifecycle exercise bike
workout programs that set a target heart rate zone first calculate the user's theoretical maximum
heart rate by subtracting the user's age from the number 220. The programs then calculate the
†
target zone as a percentage of the theoretical maximum.

When prompted by the MESSAGE CENTER to enter a time, use the ARROW KEYS to increase
or decrease the displayed time to the desired value, and press ENTER.

When prompted by the MESSAGE CENTER, use the ARROW keys to increase or decrease the
displayed intensity level or target heart rate* to the desired value, and press ENTER. Adjust the level
as needed or desired during the workout.
• Intensity level: The Lifecycle exercise bike provides a selection of 20 intensity levels. The
intensity level appears in the WORKOUT PROFILE window as rows of lights arranged in
columns. Selecting a low intensity level at first is recommended. As physical conditioning
improves, the levels can increase.
• Target heart rate: Exercise bike programs that calculate a target heart rate base this number
on the age of the user and the type of workout. The user accepts or adjusts the rate when
setting up the workout. During the workout itself, the program reads the heart rate, which is
transmitted via the Polar heart rate chest strap or through to contact heart rate electrodes;
and it uses this data to adjust the resistance. Manually raising the rate increases the intensity
of the cardiovascular exercise.

Two workout mode options on the Lifecycle exercise bike feature alternate ways to vary workouts.
• Bike Mode: This workout mode simulates the experience of riding a real bicycle. The rate
of calories burned, and total distance travelled increase automatically as the user increases
the pedaling speed. This mode can be used with all workouts, except for FAT BURN and
CARDIO. To select Bike mode, press BIKE MODE key.
• Constant-Calories-Per-Hour Mode: This workout mode enables a user to maintain a
consistent rate of calories burned per hour. As the pedaling speed increases, the resis-
tance level automatically decreases. As the pedaling speed decreases, the resistance
level automatically increases. This mode can be used with all workouts. To select it,
press the CONSTANT CAL./HR. key.
If the user selects a FAT BURN or CARDIO during the setup, the default mode is Constant-
Calories-Per-Hour. For all other workouts, the default mode is Bike. The user may select or
change a mode during a workout setup or during a workout.
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 CARDIO
workout is 144. This workout targets 80 percent of the maximum, so the equation would be (220-40)*.80=144.
