1.2 SETUP
Read the entire Operation Manual before setting up the cross-trainer.
WHERE TO PLACE THE CROSS-TRAINER
Following all safety instructions in Section 1.1, move the cross-trainer to the location in which it will be used. See
Section 5, titled Specifications, for the dimensions of the footprint. Allow one foot (30.4 cm) of clearance in front of the
cross-trainer to allow for movement of the pedal levers. It should be easy to mount the cross-trainer from the side.
HOW TO STABILIZE THE CROSS-TRAINER
After placing the cross-trainer in position, check the unit's stability by attempting to
rock it in all directions. Any slight rocking indicates that the unit must be leveled.
Determine which foot is not resting completely on the floor. Loosen the jam nut (A)
with an open-end 17mm wrench, and rotate the stabilizing foot (B) to lower it. Verify
that the cross-trainer is stable, and repeat the adjustment as necessary until the
unit no longer rocks. Lock the adjustment by tightening the jam nut against the sta-
bilizer bar. It is extremely important that the stabilizing leg be correctly adjusted
for proper operation.
PLUG IN THE CROSS-TRAINER
The cross-trainer comes with a standard power supply for the U.S., or a power
supply with country-specific line cords.
Insert the power adapter jack (C) into the barrel plug on the back of the cross-
trainer. Then insert the power supply into the wall outlet. Make sure the cord is
routed so that it doesn't bind and will not be walked on.
Check that the console LEDs light up. If not, recheck the plug and wall connec-
tions and make sure the wall outlet has power.

mount the Cross-Trainer.
3.2 BIOMECHANICAL GUIDELINES
There are two exercise variations that can be performed on the Cross-Trainer. For each variation, it is important to follow
these general biomechanical guidelines as well as the specific instructions listed below.
GENERAL
• Feet should be in a comfortable position facing forward on the pedals so the knees move in a forward plane (not angled
inward or outward) and so the hips do not rotate outward.
• Keep back straight. Do not bend forward at the waist.
• Keep both feet on the pedals at all times.
• If desired, allow heels to slightly lift off the pedals during the motion.
• Do not lock knees during the workout. Keep them slightly bent throughout the motion.
FORWARD MOTION – TOTAL BODY
• Mount the Cross-Trainer facing forward
• Hands should be positioned comfortably on the moving handles such that the elbow creates a 90 degree angle when the
moving handlebar is rotated toward you
• Choose the desired workout profile and duration on the console
• Begin moving feet in a smooth forward pedaling motion by pushing top foot forward and pulling bottom foot backward
• Exercise at a speed that is comfortable for you

REVERSE MOTION – TOTAL BODY
• Mount the Cross-Trainer facing forward
• Hands should be positioned comfortably on the moving handles such that the elbow creates a 90 degree angle when the
moving handlebar is rotated toward you
• Choose the desired workout profile and duration on the console
• Begin moving feet in a smooth reverse pedaling motion by pulling top foot backward and pushing bottom foot forward
• Exercise at a speed that is comfortable for you
BRAKING RESISTANCE
The Life Fitness Cross-Trainer features speed-dependent braking resistance. For a set resistance level on the monitor, the resistance
increases with speed. The faster you go, the greater the resistance. The computer makes no adjustments to maintain the resistance
level based on your speed.

4THE WORKOUTS
4.1 WORKOUT OVERVIEWS
This section lists the cross-trainer’s pre-programmed workouts. For more detailed information, see Section 4.2, titled
Setting Up and Using the Workouts.
QUICK START MANUAL MODE is the fastest way to begin exercising, and it bypasses the steps involved in selecting a
specific workout program. After the START key is pressed, a constant-level workout begins. The resistance level does
not change automatically.
INTERVAL combines “hills” and “valleys” of different resistance levels, which is proven to provide effective,
time-efficient cardiovascular results.
RANDOM is an interval training workout for which the user selects a computer-generated profile of varying intensity levels.
MANUAL is a workout in which the resistance level does not change automatically.
PEAK is intended to burn fat by building up to, and maintaining, a constant level of resistance throughout the workout.
SLOPE gradually increases the intensity throughout the workout duration. It is intended to strengthen the heart, as well
as the major muscle groups that are most active during the workout, such as the leg muscle groups.
CHALLENGE begins at a high resistance level and maintains this level throughout the duration.

16
4.2 SETTING UP AND USING THE WORKOUTS
To activate the console, press any key, or simply start pedaling. When the console display lights up, either select QUICK
START MANUAL MODE, or select a specific workout. Setting up a specific workout involves five steps, which are
described in this section:
1. Selecting a workout
2. Entering a workout duration
3. Entering a weight
4. Selecting a level
5. Starting the workout (pressing START) or ENTER
SELECTING AND USING QUICK START MANUAL MODE
Press the START key to begin a 30-minute MANUAL workout immediately. Once the workout is in progress, it is possi-
ble to change the resistance level using the ARROW keys.
SELECTING A WORKOUT
Press the ARROW KEYS until the LED display for the desired workout lights up. Then, press ENTER to confirm the workout
selection.
ENTERING A WORKOUT DURATION
After a workout is selected, the top DATA WINDOW flashes a default workout duration of 30 minutes. Press ENTER to
accept the default. Or, to change the duration, use the ARROW keys. Then, when the desired duration appears in the
DATA WINDOW, press ENTER to accept the duration. It is not possible to change the duration of a workout-in-progress.

17
ENTERING A WEIGHT
After a workout is selected, the top DATA WINDOW flashes a default weight. Press ENTER to accept the default. Or, to
change the weight, use the ARROW keys. Then, when the weight appears in the DATA WINDOW, press ENTER to
accept it. The on-board computer calculates the number and rate of calories burned using the entered weight as well as
the pedaling speed.
SELECTING A LEVEL FOR A MANUAL WORKOUT
After a duration is entered, the bottom DATA WINDOW flashes a default resistance level of “1”, which is the easiest of
the 16 resistance levels. Press ENTER to accept the default. Or, to change the level, use the ARROW keys. Then, when
the desired level appears in the DATA WINDOW, press ENTER to accept the duration. While the workout is in progress,
it is possible to change the resistance level (1-16).

EXPLANATION OF DIFFICULTY LEVELS
The difficulty level table shows the resistance level range at each difficulty level. Since some workouts have predeter-
mined profiles, a resistance level range had to be created. This allows the user to set a difficulty level of 1 - 9, which will
adjust the entire workouts intensity level.
STARTING A WORKOUT
After accepting a level, press START to begin the workout.
18

19
USING WORKOUTS IN PROGRESS
The cross-trainer MANUAL program features 16 resistance levels, with “1” being the easiest and “16” being the most
difficult. The cross-trainer RANDOM, SLOPE, INTERVAL, PEAK, and CHALLENGE programs feature 9 difficulty levels,
with “1” being the easiest and “9” being the most difficult. While a workout is in progress, it is possible to change the
level of the overall workout. To do so, simply press the UP or DOWN arrow keys repeatedly until the DATA DISPLAY
window shows the desired level. That change remains in effect for the entire workout or until the level is changed again.
