ENTERING AGE
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. 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.
ENTERING TIME
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.
SELECTING AND ADJUSTING THE RESISTANCE LEVEL
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.
• Resistance level: The Life Fitness cross-trainer provides a selection of 20 resistance levels. The resistance 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: 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 Lifepulse system sensors or the Polar heart rate chest strap; and it
uses this data to adjust the resistance. Manually raising the rate increases the intensity of the cardiovascular exercise.
