CARDIO
The CARDIO workout is virtually identical to FAT BURN; however the target heart rate is calcu-
lated at 80 percent of the theoretical maximum†(HRmax)**. The higher target promotes cardio-
vascular improvement by placing a heavier workload on the heart muscle.
NOTE: The intensity level is changed by incline. Speed can be only changed by the user.
NOTE: Change the target heart rate at any time by using the NUMERIC KEYPAD.
HILL
The Life Fitness-patented HILL workout offers a variety of configurations for interval training. Intervals
are periods of intense cardiovascular exercise separated by regular periods of lower-intensity exer-
cise. The WORKOUT PROFILE window represents these high and low intervals as columns of illumi-
nated LEDs, which together have the appearance of hills and valleys. The computerized interval
training workout has been scientifically demonstrated to promote greater cardiorespiratory improve-
ment than steady-pace training.
The HILL workout goes through four phases, each marked by different intensity levels. The WORK-
OUT PROFILE window displays the progress of these phases. As noted in the descriptions below,
the heart rate should be measured at two stages in the workout to gauge its effectiveness. Wear the
chest strap or continuously grip the LifepulseTM handles. The MESSAGE CENTER does not display a
request for a heart rate measurement, as it does with CARDIO, FAT BURN and the HEART RATE
ZONE TRAINING programs.
1 Warm-up is a phase of low, gradually rising resistance, which brings the heart rate into the
lower end of the target zone and increases respiration and blood flow to working muscles.
2 Plateau increases the intensity slightly, and keeps it steady, to bring the heart rate to the low
end of the target zone. Check the heart rate at the end of this phase.
3 Interval Training is a series of increasingly steeper hills, alternating with valleys, or stints of
recovery. The heart rate should rise to the high end of the target zone. Check the heart rate
at the end of this phase.
4 Cool-down is a low-intensity phase that allows the body to begin removing lactic acid, and
other exercise by-products, which build up in muscles and contribute to soreness.
4.3 WORKOUT DESCRIPTIONS
GOSYSTEM QUICK START
QUICK START is the fastest way to begin exercising. After the QUICK START key is pressed, a
MANUAL workout begins, at a very slow speed and with the incline level is set to zero by default.
Change the speed using the WALK, JOG or RUN key to jump to a preset speed, use the SPEED
ARROW keys to gradually move the speed up or down as desired, or use the NUMERIC keypad to
enter a new speed value. Change the incline level using the LOW, MID or HIGH key to jump to a
preset incline, use the INCLINE ARROW keys to move the incline gradually up or down as desired,
or use the NUMERIC keypad to enter a new incline value. For accurate caloric expenditure, enter
your weight using the ENTER WEIGHT button. The preset speeds and inclines are as follows:
English Metric Default
Default Units Default Units Incline Level
WALK 2.0 mph 3,0 kph LOW 1.5%
JOG 4.0 mph 6,0 kph MID 3%
RUN 6.0 mph 9,0 kph HIGH 5%
To redefine a preset speed, enter any non-FIT TEST workout. Press the SPEEDARROW keys
to adjust the speed value displayed in the MESSAGE CENTER, or the INCLINE ARROW keys
to adjust the incline value displayed in the MESSAGE CENTER. Press and hold the WALK,
JOG, RUN, LOW, MID or HIGH key until the console beeps twice, indicating that the new speed
has been programmed. Note that the WALK speed must be lower than the JOG speed, which
much be lower than the RUN speed, and the LOW incline must be lower than the MID incline,
which must be lower than the HIGH incline, or the treadmill will reject your change, signaled with
a beep.
NOTE: All changed preset values are preserved when the treadmill is turned off.
NOTE: It is possible to program the WALK, JOG, and RUN speed values and LOW, MID
and HIGH incline values in pre-programmed workouts (MY WORKOUTS) - each workout
may have a different setting for the six Go System Quick Start keys.
MANUAL
The MANUAL program is a constant effort workout in which the user can change resistance
level or speed at any time.
RANDOM
The RANDOM program creates a terrain of hills and valleys that varies with each workout. More
than one million different patterns are possible.
FAT BURN
The FAT BURN workout is designed to maintain a user’s heart rate at 65 percent of the theoretical
maximum†(HRmax) for optimal results. Throughout the workout, the user wears a chest strap or
grasps the LifepulseTM sensors. If the user is not wearing a chest strap, the WORKOUT PROFILE
WINDOW displays a heart shape, and the MESSAGE CENTER displays a prompt to grasp the
sensors. The console continuously monitors and displays the heart rate, adjusting the intensity level
of the treadmill to reach and maintain the target*. This system eliminates over- and under-training,
and it maximizes the aerobic benefits of exercise by using the body's fat stores for fuel.
NOTE: The intensity level is changed by incline. Speed can be only changed by the user.

†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 (HRmax). A 40-year-old user's recommended THR
for the CARDIO workout is 144, or 80 percent of the maximum; so the equation would be (220-40)*.80 = 144.
