INTRODUCTION
Congratulations . . . and thank you for purchasing a Life Fitness 3500 treadmill. Your
new Life Fitness aerobic trainer is the most versatile in-home treadmill ever developed,
the culmination of over 20 years of Life Fitness research, technological innovation and
engineering expertise. It is recognized as one of the world's most popular and advanced
computerized running/walking machines.
Like other Life Fitness products, the Life Fitness 3500 treadmill is designed to provide
you with an effective workout that is both motivating and time efficient, without the stress
and strain on legs and joints caused by some other forms of exercise. A user-friendly
console displays a host of visual feedback in addition to acting as your personal “coach”
with easy-to-follow prompts and instructions.
Who uses Life Fitness treadmills? People who value their time and recognize the
importance of regular exercise. Olympic athletes, movie stars, business executives,
government officials, sports celebrities and others all make Life Fitness treadmills their
exercise choice. Whether at home or in the office, using a Life Fitness treadmill is an
excellent way to lose weight and improve your cardiorespiratory condition — and it's fun!
Why use a Life Fitness treadmill? Aerobic training with a Life Fitness 3500 treadmill is
more than just a motivating experience. Regular aerobic exercise improves your energy
and endurance, reduces body fat, lowers your risk of heart disease, and tends to prolong
life* — not to mention making you look and feel better and more confident. Competitive
athletes train aerobically to increase their heart strength, lung capacity and muscular
endurance, and working out consistently can help all of us deal with everyday stress.
lIt's Intelligent: Choose from the five standard Life Fitness workout programs,
or the Heart Rate Zone Training™ program (Zone Trainer™ heart rate monitor sold
separately). This heart rate training system uses the most accurate heart rate
readings available and maintains your target heart rate by automatically adjusting
incline, giving you the full benefits of aerobic training.
lIt's Motivating: An easy-to-read message center displays motivating feedback of
your workout so you'll always know how you're doing. Your elapsed time, calories
burned per hour, total calories burned, actual walking or running speed, distance
traveled, and terrain are continually displayed.
lIt's Easy: The user-friendly computerized console guides you through every step
of your workout.
If you have any questions regarding the operation of your Life Fitness 3500 treadmill,
please call Life Fitness Customer Support Services at [phone] or toll free with-

Lifetime Exercise for Health and Fitness

6
Numerous scientific and medical studies demonstrate that lifetime consistency is the
key to achieving the most important health benefits from exercise, and interval striding is
the ideal form of exercise for a lifetime of health and fitness. It features the easy, natural
activity of striding and adds the benefits of interval training. Its low-impact nature reduces
the chances of injury, and the motivational features of the Life Fitness 3500 treadmill
assure the enthusiasm and enjoyment so essential to making exercise a lifelong habit.
The Life Fitness 3500 Treadmill: The Ultimate Striding Machine
The Life Fitness 3500 treadmill is loaded with features designed to make interval
striding comfortable, motivational and safe. The FlexDeck™ striding surface minimizes
impact to bones and joints; the quiet — yet powerful — motor allows belt speeds from
0.5 to 9.0 mph, .81 to 14.5 kph on metric units; and the ergonomically-designed side rails
remain out of the way. The Life Fitness 3500 treadmill is truly the fitness machine of the
’90s and beyond for walking, running and interval striding.

GROUNDING INSTRUCTIONS
For safe operation, your Life Fitness 3500 treadmill MUST be properly grounded.
Should the unit malfunction, proper grounding provides a path of least resistance for the
electric current, which reduces the risk of electrical shock to anyone touching or using
the unit. Each unit is equipped with an electrical cord with an equipment grounding
conductor and a grounding plug. The unit must be plugged into an appropriate outlet
that is properly installed and grounded in accordance with local codes and ordinances.
A temporary adapter may be used to connect this plug to a 2-pole receptacle in the U.S.
and Canada if a properly grounded outlet is not available. A TEMPORARY ADAPTER
SHOULD BE USED ONLY UNTIL A PROPERLY GROUNDED OUTLET CAN BE
INSTALLED BY A QUALIFIED ELECTRICIAN.
DANGER: Electrical shock may result from improper connection of the equipment
grounding conductor. Check with a qualified electrician if you are in doubt as to proper
grounding techniques. DO NOT modify the plug provided with the product. If it does not
fit your electrical outlet, have a proper outlet installed by a qualified electrician.
L’exerciseur de marche Life Fitness 3500 DOIT être mis à la terre correctement pour
assurer un fonctionnement sans danger. En cas de mauvais fonctionnement, la mise à la
terre assure un parcours de moindre résistance pour le courant électrique, ce qui réduit
les risques de secousse électrique pour la personne qui touche ou qui utilise l’appareil.
Chaque unité est munie d’un cordon électrique, d’un fil de terre et d’une fiche de terre.
L’unité doit être branchée dans une prise de courant adéquate. La prise doit être cor-
rectement installée et mise à la terre conformément aux codes et aux règlements locaux.
DANGER: Une mauvaise connexion du fil de terre pourrait causer une secousse
électrique. Si vous avez des doutes quant aux techniques appropriées de mise à la
terre, consultez un électricien qualifié. NE modifiez PAS la fiche qui est comprise avec
l’appareil. Si vous ne pouvez utiliser la fiche dans la prise de courant, demandez à un
électricien qualifié d’installer une prise adéquate.

HEART RATE ZONE TRAINING™
Research shows that exercising within a predetermined heart rate range is the best way
to both measure your exercise intensity and achieve optimal results. That’s the idea
behind the Life Fitness Heart Rate Zone Training approach to exercise.
Heart Rate Zone Training takes the guesswork out of working out correctly by auto-
matically adjusting the incline of your Life Fitness 3500 treadmill to keep you at your
target heart rate - you can’t under-train or over-train - and you can target your heart rate
to your individual fitness goals!
If your primary goal is to burn fat, you should exercise at a level between 60% and 75%
of your theoretical maximum heart rate (defined by the American College of Sports
Medicine as 220 minus your age). If you wish to improve your cardiovascular condition,
you should work out at 75% to 85% of your theoretical maximum heart rate.
Example: Let’s say you are 30 years old. Your theoretical maximum heart rate is
220 - 30 (your age) = 190 beats per minute (bpm).
If your primary goal is to burn fat:
Multiply 190 x .60 = 114 bpm (this is the low end of your target heart rate zone);
Multiply 190 x .75 = 143 bpm (this is the high end of your target heart rate zone);
If your primary goal is to improve your cardiovascular fitness:
Multiply 190 x .75 = 143 bpm (this is the low end of your target heart rate zone);
