INTENSITY LEVEL
The Life Fitness Treadmill provides several different ways to adjust the intensity level of an workout.
When prompted, use the ARROW keys to increase or decrease the displayed intensity level or tar-
get heart rate* to the desired value, or choose the desired value with the NUMERIC KEYPAD, and
press ENTER. Adjust the level as needed or desired during the workout.
• Intensity level: The Life Fitness Treadmill provides a selection of 20 intensity levels. Each level
represents a range of incline percentages. (See Section 4.4 Maximizing Workouts on a Life
Fitness Treadmill for a chart showing all 20 levels.) The Workout Profile Window displays the
levels of intensity in a workout-in-progress as proportional columns. The height of the column
furthest to the left is proportional to the current level of intensity. 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 Polar
heart rate chest strap or the Lifepulse system sensors; and it uses this data to adjust the resis-
tance. Manually raising the rate increases the intensity of the cardiovascular exercise.
4) ENTERING WORKOUT VALUES
AGE: When prompted to enter Age, use the ARROW KEYS to increase or decrease the displayed
age to the correct value, or key in the correct value with the NUMERIC KEYPAD, and press ENTER.
Life Fitness Treadmill 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.
WEIGHT: Select weight and press enter. Entering an accurate weight allows for a more accurate
calorie calculation and for Watts and METs to be computed and displayed.
GENDER: Select gender and press enter. (Used for the Fitness Testing workouts)
* 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.
