CHAPTER ONE: INTRODUCTION  
Your new CS 8.0 Bike console, the CS 8.0 console, is the most  
sophisticated exercise computer in the fitness industry. Even the  
simplest operation, Manual Control, works in a special and  
useful way. But the CS.80 console is also extremely easy to use; the  
user can ignore all the fancy stuff and use it with just one or two  
keystrokes.  
Introduction  
Smart Start: Intelligently picks useful workout settings — every  
Top  
Features  
workout, even an advanced one, is easy to set up.  
Always-available Workout Setup: Switch to this at any time in  
any workout. Adjust your current workout settings, or set up a  
whole new workout.  
Calorie Goal: Tell the bike how many calories you want to burn  
and how long you want to work out, and the bike figures out what  
workloads you need to maintain — including warmup and cool  
down.  
Constant Heart Rate Control: The bike takes you to your target  
heart rate within five to eight minutes, then keeps you there.  
Interval Heart Rate Control: Pick both a work target HR and a  
rest target HR, and the bike will take you back and forth between  
those two targets.  
Fitness Test: An enhanced version of the YMCA protocol to  
estimate maximum oxygen uptake (VO2max).  
Bicycle Simulation: An accurate simulation of a 21-gear road  
bike, including precise pedal cadence-to-speed response and body  
weight compensation.

Improved Maximum Heart Rate Estimates: Instead of the “220  
- age” formula, the CS 8.0 console uses a newer, more accurate  
formula created by exercise physiologists in 1994.  
Medical and Ergometer Modes: Feature-restricted modes suitable  
for rehabilitation and informal testing environments, with user-  
selectable pedal rpm limiting.  
Happy Workout: If riders want to think they’re burning lots of  
calories when they are actually hardly working at all, this workout  
is for them.

place the ball of their foot in the  
center of the pedal.  
Other riders are more comfortable  
if the arch of their foot is against the  
pedal. Riders are encouraged to be as  
efficient as possible, but use your own  
judgement in the comfort/efficiency  
tradeoff.  
Most riders will find a comfort/efficiency sweet spot at a  
pedal cadence around 80 rpm. More serious riders desiring  
maximum performance typically pedal at around 100 rpm. For  
electromechanical and safety reasons, the bike will not provide  
the fully requested workload when your pedal cadence falls below  
55 rpm. It will, however, accurately display the workload it does  
provide. For additional safety, cadence is workload limited.  
Pedal  
Cadence  
Breathe in a regular and relaxed manner. Many exercisers do  
not breathe enough, which reduces their exercise capacity and  
comfort. You might want to try breathing deeper and more  
frequently to see if it helps your exercise regime.

Monitoring Your Heart Rate  
CHAPTER TWO: RIDING YOUR BIKE  
The CS 8.0 Bike has two ways of monitoring your heart rate:  
Monitoring  
Your Heart  
Rate  
...By using a chest strap that transmits your heart rate to the bike  
via radio...  
...or by using the metal contact heart rate pads on the handlebars.  
Upright Upper HRC Pads  
Upright Lower HRC Pads  
Recumbent HRC Pads  
Although your bike functions fine without using the heart rate  
monitoring feature, this kind of monitoring gives you valuable  
feedback on your effort level. Chest strap monitoring also allows  
you to use Heart Rate Control, which is the most advanced  
exercise control system available.

Chest Strap Use  
CHAPTER TWO: RIDING YOUR BIKE  
When you wear a Polar or compatible transmitter strap, the bike  
will display your heart rate as a digital beats-per-minute (bpm)  
readout. This monitoring is very accurate, typically within one

Some moisture is necessary between the strap and your skin.  
Sweat from your exercise works best, but ordinary tap water may  
be used prior to your workout if desired.

Contact Heart Rate Use  
CHAPTER TWO: RIDING YOUR BIKE  
The contact heart rate system lets you monitor your heart rate  
without wearing a strap.  
Contact  
Heart Rate  
(CHR)  
A Note on CHR Accuracy  
Gently grasp the contact heart  
rate pads as shown below.  
CHR monitoring may be a bit  
less accurate than a chest strap,  
since the heart rate signals are  
much stronger at the chest.  
The CS 8.0 Bike uses the most  
advanced CHR system avail-  
able. It converts your heart rate  
waveform to a digital signal,  
then analyzes the digitized  
waveform to pick out the  
When the system detects your  
hands, the heart rate LED  
will flash in time with your

electrocardiogram shape and  
thus the heart rate.  
About 5% of the population  
cannot be picked up by any CHR  
system. This is because their  
heart is positioned in a more  
up-and-down manner in their  
chest, as opposed to leaning over  
to one side.

Getting the Most From CHR  
CHAPTER TWO: RIDING YOUR BIKE  
1. Exercise with smooth body motions. Avoid excessive body  
motion, especially in your arms and upper body.  
For Best  
Results  
2. Breathe smoothly and regularly, and avoid talking. (Talking  
will cause unrepresentative heart rate spikes of 5 to 10 bpm.)  
3. Grip the pads lightly, not tightly.  
4. Make sure your hands are clean, free of both dirt and hand  
lotions.  
When using a Heart Rate Control (HRC) workout or the Fitness  
Test, it is best to use chest strap monitoring. These workouts  
work best with the extra accuracy gained from a chest-contact  
heart rate monitoring system.  
A wall transformer external power option is available which gives  
the CS 8.0 Bike some additional capabilities:  
External  
Power  
Option  
• The bike’s display is always lit in Attract Mode (see  
Chapter 13). This can make the bike more friendly and  
interesting to prospective riders.  
Test Mode diagnostics are more versatile (see Chapter 15).  
• The bike’s minimum workload is lower, which is required  
by the Medical and Ergometer modes (see Chapter 11)  
and recommended for the Fitness Test (see Chapter 10).

Personal Power Fine Control  
CHAPTER FIVE: MANUAL CONTROL  
Manual Control can operate three different ways: Personal Power  
Fine Control, Bike Mode, and 10-watt mode.  
Introduction  
In all modes, change levels either by using the  
,
keys, or  
entering a workload level with the numeric keys and pressing  
.
Personal  
Power Fine  
Control  
This default manual control has 77 different levels (for a 150-  
pound rider), allowing you to fine-tune your workout. Since  
Personal Power is used, the number of levels available decreases  
for larger riders. This mode uses constant power workload  
control (see Appendix C).  
Bike Mode  
The second mode is Bike Mode, which simulates a 21-speed  
road bike, compensating for body weight with Personal Power,  
simulating air resistance, and computing speed correctly for the  
selected gear and cadence. The 21 “gears” are like that of a bike  
that has gearing from 50 to 105 inches.  
Bike Mode uses constant torque (see Appendix C), then adds  
additional workload for the simulations and compensations. The  
calculations are adapted from the power formulas in Bicycling  
Science, the leading reference in this field (see Bibliography).  
10-Watt  
Mode  
The final mode is a conventional 10-watt increment constant  
power mode.

weights.  
Each workout segment can  
have a value between 1 and  
8. The overall workout can be  
adjusted to 16 possible levels.  
The workload level of a work-  
out segment is calculated by  
the formula.  
The two hill programs are:  
• Rolling Hills, a series of  
gently changing workloads.  
• One Big Hill, with the  
workload gradually  
METs = (scaler1 * segment) *  
(scaler2 * level) + 2  
increasing to a maximum  
at the halfway point, then  
decreasing gradually to the  
end.  
METs are then converted to  
T-Mets.  
The two interval programs are:  
Scaler1 and scaler2 are math-  
ematical formulas which  
subtly change the scale and  
magnitude of both the seg-  
ment and level variables.  
• Easy intervals, with a  
moderate change between  
work and rest intervals.  
• Sport intervals, with a large  
change between work and

Introduction to HRC  
CHAPTER SEVEN: HEART RATE CONTROL  
True’s heart rate control (HRC) workouts let the bike monitor  
your relative exercise intensity by way of your heart rate, then  
automatically adjust the workload to keep you at your target  
heart rate and thus your desired exercise intensity.  
Constant  
HRC  
Your heart rate is a good measure of your body’s exercise stress  
level. It reflects differences in your physical condition, how tired  
you are, the comfort of the workout environment, even your diet  
and emotional state. Using heart rate to control workload takes  
the guesswork out of your workout settings.  
Consult your physician before using heart rate controlled  
workouts for advice on selecting a target heart rate range. Also,  
it is important to use the bike for several workouts in the manual  
mode while monitoring your heart rate. Compare your heart rate  
with how you feel to ensure your safety and comfort.  
See Appendix A for a chart that may help you pick a target heart  
rate.  
You need to wear a heart rate monitoring chest strap to use heart  
rate control. See the “Monitoring Your Heart Rate” section in  
Chapter 2 for a guide to proper usage. It is not recommended  
that you use the contact heart rate system for heart rate control  
workouts.

Types of HRC  
CHAPTER SEVEN: HEART RATE CONTROL  
The CS 8.0 Bike has five types of heart rate control:  
Types of  
HRC  
• Constant: pick a target heart rate, and the bike will control  
your workout from the very beginning so that you reach  
your target within five to seven minutes.  
• Interval: pick both a work target and a rest target heart rate.  
The bike will take you back and forth between these two  
targets.  
• HRC Ultra: simulates a real high-intensity workout by  
automatically raising your target heart rate as you proceed  
through the last half of your workout.  
• HRC Ultra Interval: simulates a real interval workout, with  
progressively higher targets for each work and rest interval.  
• Cruise Control: while in any program, set your current heart  
rate as your target by pressing a single key.

Constant and Interval HRC  
CHAPTER SEVEN: HEART RATE CONTROL  
This is the best-known type of HRC, and is the easiest to use.  
The bike will gradually raise your heart rate so that you reach  
your target within five to seven minutes. It keeps you there until  
2.5 minutes before the end of your workout time, then reduces  
workload by half for a cooldown.  
Constant  
HRC  
Note that as you tire during your workout, especially in the last  
third, workload will usually have to be reduced to keep you at a  
steady target heart rate.  
To change your target heart rate, press the  
one bpm at a time, or enter a new target with the numeric keys  
and press  
,
keys to change  
.
This allows you to do a classic interval workout with the bike  
controlling all workloads, including the rest segments. After  
reaching your work target just like in Constant HRC, the  
workload is immediately reduced by 65%, then controlled so you  
reach your rest target within about three minutes.  
Interval  
HRC  
As soon as you reach your rest target, the workload is  
immediately increased to the last workload attained in the work  
segment, then controlled to reach your target within about two  
minutes.  
This pattern repeats until 2.5 minutes before the end of your  
workout time, then reduces workload to the last rest segment  
workload.  
To change your work or rest targets, press the  
,
keys to  
change one bpm at a time, or enter a new target with the numeric  
keys and press  
.

HRC Ultra Overview  
CHAPTER SEVEN: HEART RATE CONTROL  
As mentioned in the Constant  
Why Use  
HRC Ultra  
Workouts?  
HRC section, as you tire in the  
last third of your workout, your  
heart rate has a tendency to rise,  
which Constant HRC addresses  
by reducing workload.  
However, exercisers who are  
really serious and in very good  
condition always let their heart  
rates rise during the last third  
of their workouts, usually to  
very high levels. The HRC  
Ultra workouts are designed  
to simulate this kind of high-  
intensity workout.  
Do not attempt these work-  
outs unless you are certain  
you are in good medical and  
physical condition. Failure  
to observe this warning may  
result in shortness of breath,  
dizziness, or death

HRC Ultra Workout  
CHAPTER SEVEN: HEART RATE CONTROL  
Unlike Constant and Interval HRC, you don’t pick a target heart  
rate, but you must enter your age correctly.  
HRC Ultra  
Workout  
For the first fifth of your workout time, HRC Ultra tries to  
increase your heart rate to 70% of your maximum heart rate  
(HRmax) within three to four minutes.  
In the middle three-fifths of your workout, HRC Ultra increases  
your heart rate to 88% HRmax within three to four minutes, and  
then maintains that heart rate.  
During the final fifth of your workout, HRC Ultra tries to raise  
your heart rate to 97% HRmax by the time you reach one minute  
to go in your workout time.  
Note: if you prefer lower (“less Ultra”) heart rate targets in either  
Ultra workout, you can reduce the targets across the board by  
pressing the  
key.

Interval HRC Ultra Workout  
CHAPTER SEVEN: HEART RATE CONTROL  
Interval HRC Ultra works similarly to Interval HRC, but the  
work target heart rates gradually increase through your workout.  
The first work segment target is 88% HRmax, and the last work  
segment target is 97% HRmax.  
Interval

The rest segment target is 65%. Note that workload usually has  
to be greatly decreased to allow you to reach this low a heart rate

Cruise Control  
CHAPTER SEVEN: HEART RATE CONTROL  
This is the simplest way to enter Constant HRC training. While  
in manual or any program you can enter Constant HRC by simply  
pressing the Heart Rate Control key. Your current heart rate will  
be set as the target.  
Cruise  
Control  
For best results, you should be at least five minutes into your  
workout and warmed up. This will allow Cruise Control to more  
accurately control your heart rate.  
Remember, you must be wearing a chest strap, and your heart  
rate should be displayed in the Heart Rate window.  
To change your target heart rate, press the

Important Points About HRC  
CHAPTER SEVEN: HEART RATE CONTROL  
The heart rate monitor transmitter strap should be worn  
Important  
Points  
About  
Heart Rate  
Control  
according to the guidelines in Chapter 2.  
If the transmitter strap is adjusted or moved while exercising,  
heart rate monitoring may be temporarily affected.  
If communication is lost for 30 seconds, the bike will exit the  
HRC workout into a manual workout.  
The transmitter strap sends a low-level radio signal to the bike,  
so interference from other radio and sound waves (including  
everything from cordless telephones to loudspeakers) is possible.  
The good news is that interference is usually quite brief. If you  
continue to have intermittent heart rate display problems, consult  
your local service technician, as the transmitter strap batteries  
may be low.  
Make sure you breathe smoothly and regularly.  
Talking during your workout usually causes heart rate spikes  
of five beats per minute or more, so avoid talking as much as  
possible.  
Maintain a smooth pedaling motion.  
Two users wearing the same kind of transmitter at the same time  
and in close proximity may cause false heart rate display readings.

CHAPTER EIGHT: CALORIE GOAL WORKOUT  
Calorie Goal lets you pick a total number of calories and workout  
time, then calculates a steady-state exercise at a work level  
(Cruising Watts) so that you reach your target total calories at  
the end of a 2.5-minute cooldown. There is a 2.5-minute warmup  
prior to Cruising Watts.  
Setting Up  
A Calorie  
Goal  
Workout  
Calorie Goal is especially useful if you exercise to help with  
weight loss or weight control. You might have a specific number  
of calories you wish to burn in each exercise session. Also, you  
sometimes have different amounts of time available to exercise.  
Calorie goal is the easiest way to achieve your exercise goal, no  
matter what your schedule.  
To change your calorie goal, press the  
calorie at a time, or enter a new calorie goal with the numeric  
keys and press  
,
keys to change one  
.
Some guidelines: Your workout time must be at least six minutes.  
If Cruising Watts are 400 or more, a warning will be displayed.  
The program will not accept a workout setup if Cruising Watts  
are above 600.

Introduction & How to Test Yourself  
CHAPTER TEN: FITNESS TEST  
The CS 8.0 Bike fitness test is an improved implementation  
of the YMCA protocol fitness test, as described in the ACSM  
Guidelines, Chapter 4. (See Bibliography.) The bike must monitor  
your heart rate accurately throughout, so you should use a  
wireless transmitter strap instead of the contact heart rate pads  
(see Chapter 2). It works best with the external power option.  
Introduction  
The result of the test is an estimate of your maximal oxygen  
uptake, or VO2max (see Appendix B).  
• Press Advanced Options  
then press  
until Fitness Test appears,  
How to  
Do It  
.
• Fill out all the personal parameters. You must enter your age  
correctly.  
• Press  
.
Make sure the bike is displaying your heart rate, then pedal in  
a smooth and relaxed manner for the 12 minutes of gradually  
increasing workload. Your VO2max estimate will be displayed  
when you finish.

Proper Preparation & Behavior  
CHAPTER TEN: FITNESS TEST  
You should:  
• Stay as relaxed as possible during the test, breathing  
smoothly and regularly.  
• Be dressed in comfortable workout clothes and riding in a  
room with comfortable air temperature and humidity.  
You should not:  
• Eat within three hours prior to testing, but you should not be  
hungry, either.  
• Consume caffeine within three hours prior.  
• Smoke within three hours prior.  
• Exercise vigorously within 24 hours prior.  
• Make any unnecessary movements of arms, head, or torso.

How the Test Works  
CHAPTER TEN: FITNESS TEST  
The test consists of four three-minute stages. Stage one is a

warmup stage. Stages two, three, and four are at ever-increasing  
workloads, with your heart rate measured during the second  
and third minute of each stage. (If the two heart rate samples in  
a given stage are separated by more than six bpm, that stage is  
extended for an additional minute.)  
The heart rate measured during the last minute of each stage is  
compared mathematically with workload, and then extrapolated  
to your age-predicted maximal heart rate (see Appendix A).  
The workload corresponding to this heart rate is converted to  
milliliters of oxygen per kilogram of body weight per minute.

Test Specific Issues  
CHAPTER TEN: FITNESS TEST  
Note that the absolute accuracy of this test is approximately  
+/- 15% compared to a laboratory maximal test. (See Swain and  
Leutholtz, Metabolic Calculations, page 63). The results on the  
CS 8.0 Bike should be somewhat better since it uses an improved  
maximum heart rate formula (see Appendix A).  
Test  
Specific  
Issues  
The repeatability accuracy, from test to test with the same test  
subject, should be much better, probably within +/- 7%.

CHAPTER ELEVEN: MEDICAL AND ERGOMETER MODE  
These modes require the use of the external power option, and  
are accessed by changing the default operation mode in Setup

several ways.  
What These  
Modes Do  
These modes:  
Restrict operation to just manual and custom programs.  
Replace the normal workload control modes to  
modes more common in the rehabilitation and testing  
environments.  
Provide a unique rpm limiting feature for cases where  
excessively rapid motion is of concern.  
Work in constant power mode and, since precise  
workload control is of prime importance all the time,  
torque is not rolled off at low rpms (see Appendix C).  
Have lower than normal minimum workload, because of  
the use of external power.

How These Modes are Different  
CHAPTER ELEVEN: MEDICAL AND ERGOMETER MODE  
The two modes differ in the way they control workload:  
How These  
Modes Are  
Different  
Ergometer Mode: This emulates  
What’s a kilopond?  
This is an obsolete unit  
of force, equivalent to the  
gravitational force on one  
kilogram at the earth’s  
surface, or about 9.8 new-  
tons. Sweden made the  
kilopond its official unit  
of force in 1945, and thus  
it ended up being used  
in an ergometer made in  
Sweden. It is essentially  
equivalent to the force on  
a kilogram at the Earth’s  
surface.  
a popular cycle ergometer whose  
workload settings are in kiloponds  
(see side bar) and are adjusted by  
changing the amount of weight (in  
kilograms) at the end of a brake belt  
wrapped around a flywheel.  
Many testing protocols are written  
especially for such an ergometer.  
These protocols can now be run on  
the CS 8.0 Bike, either programmed  
into a custom program or run  
manually.  
Medical Mode: This uses either  
METs or watts, instead of kiloponds,  
for workload control. (Although  
Operations  
Restrictions  
that’s just like normal operation mode, Medical mode adds the  
previously mentioned useful functions like no torque roll-off and  
rpm limiting, and doesn’t allow riders to play around with other  
exercise modes.) Most exercise prescriptions are in either METs  
or watts, so this mode is useful for that.  
These modes restrict operation to manual and custom programs.  
Refer to Chapter 5 for manual operation and Chapter 9 for  
custom program operation.

CHAPTER TWELVE: OTHER FUNCTIONS  
Happy Workout: This allows riders to perform a virtual (i.e.,  
imaginary) world-class workout. The bike thinks the rider is  
generating six times as much power as he really is, and all the  
related workout data like speed and calories are accelerated  
as a result. One use of Happy Workout is to allow easier  
demonstration of the bike to serious riders.

Electronic Input and Output: The CS 8.0 console provides two  
communication ports, labeled “Comm” and Aux.” They use the  
CSAFE standard, typically to provide power to and communicate  
with a channel- and volume-control device for a sports club  
entertainment system such as BroadcastVision® or Cardio  
Theater®. The Audio Remote keys generate these control signals.  
The Comm port also supports the full CSAFE Level 3  
communications specification for use with fitness equipment  
networks (see <fitlinxx.com/csafe/specification.htm>)  
The Video In port is not currently used.

The F.I.T. Concept Defined  
CHAPTER THIRTEEN: DESIGNING AN EXERCISE PROGRAM  
The workout portion of your exercise program consists of three  
major variables: Frequency, Intensity, and Time.  
What is  
the F.I.T.  
Concept?  
Frequency: How Often You Exercise  
You should exercise three to five times a week to improve your  
cardiovascular and muscle fitness. Improvements are significantly  
smaller with less frequent exercise.  
Intensity: How Hard You Exercise  
Intensity of exercise is reflected in your heart rate. Exercise  
must be sufficiently rigorous to strengthen your heart muscle  
and condition your cardiovascular system. Only your doctor can  
prescribe the target training heart range appropriate for your  
particular needs and physical condition.  
Start with exercise that stimulates you to breathe more deeply.  
Alternate days of moderate and easy exercise to help your body  
adapt to new levels of exertion without unnecessary strain.  
If you are just beginning an exercise program, you may be most  
comfortable using your bike at low workloads. As you use your  
bike regularly, higher workloads may be more comfortable and  
more effective.  
If you feel out of breath before you have exercised 12 minutes,  
you are probably exercising too hard.

More F.I.T. Concept Overview  
CHAPTER THIRTEEN: DESIGNING AN EXERCISE PROGRAM  
As your fitness level improves, you will need to increase your  
workout intensity in order to reach your target heart rate. The  
first increase may be necessary after two to four weeks of regular  
exercise. Never exceed your target heart rate zone. Increase  
the workload on the bike to raise your heart rate to the level  
recommended by your doctor.  
METs  
One MET is the amount of energy your body uses when you’re  
resting. If a physical activity has an equivalent of 6 METs, its  
energy demands are six times that of your resting state. The MET  
is a useful measurement because it accounts for differences in  
body weight. See Appendix C for more details.  
Time: How Long You Exercise  
Sustained exercise conditions your heart, lungs, and muscles. The  
longer you are able to sustain exercise within your target heart  
range, the greater the aerobic benefits.  
To begin, maintain two to three minutes of steady, rhythmic  
exercise and then check your heart rate.  
The initial goal for aerobic training is 12 continuous minutes.  
Increase your workout time approximately one or two minutes  
per week until you are able to maintain 20-30 continuous minutes  
at your training heart rate.

Utilizing the F.I.T. Concept  
CHAPTER THIRTEEN: DESIGNING AN EXERCISE PROGRAM  
The F.I.T. concept is designed to help you begin a program  
tailored to your needs. You may wish to keep an exercise log to  
monitor your progress.  
Using  
the F.I.T.  
Concept  
Your  
Fitness  
Program  
You can get valuable fitness benefits from your CS 8.0 Bike. Using  
the bike regularly may increase the ability of your heart and  
lungs to supply oxygen and nutrients to exercising muscles over  
an extended period of time. The bike will also help you develop  
added muscle endurance and balanced strength throughout your  
body.  
Calculate your maximum heart rate as a first step in developing  
your fitness program. The formula to calculate average maximum  
heart rate for one minute is:  
205.8 - (0.685 * age)  
See Appendix A for the source of this formula.  
Determining  
Your Needs  
To find your pulse, locate a vein on your neck or inside your  
wrist, then count beats for 10 seconds, then multiply by six.  
It’s also important to know your target training zone or target  
heart rate. The American College of Sports Medicine (ACSM)  
suggests 55% to 65% for lower-conditioned users, 75% to 80%  
for moderately conditioned users, and up to 90% for well-  
conditioned users. (See Appendix D.)

Beginning Your F.I.T. Program  
CHAPTER THIRTEEN: DESIGNING AN EXERCISE PROGRAM  
In addition to monitoring your heart rate as you exercise, be  
certain of how quickly your heart rate recovers. If your heart rate  
is over 120 beats per minute five minutes after exercising, or is  
higher than normal the morning after exercising, your exertion  
may be too strenuous for your current level of fitness. Reducing  
the intensity of your workout is recommended.  
The age-adjusted target heart rates indicated in Appendix A  
reflect averages. A variety of factors (including medication,  
emotional state, temperature, and other conditions) can affect the  
exercise heart rate appropriate for you.  
Warning: Consult your doctor to establish the exercise intensity  
(target heart rate zone) appropriate for your age and condition  
before beginning any exercise program.  
Beginning  
Your  
Warm-Up: Slow and Deliberate Exercise  
Exercise  
Program  
You are not warmed up until you begin to perspire lightly and  
breathe more deeply. Warming up prepares your heart and other  
muscles for more intense exercise and helps you avoid premature  
exhaustion. Start slowly, exploring different workloads until you  
can comfortably sustain your exercise level. A good suggestion is  
a minimum of three minutes. Perspiration on your brow is a good  
indicator of a thorough warm-up. The older you are, the longer  
your warm-up period should be.

CHAPTER THIRTEEN: DESIGNING AN EXERCISE PROGRAM  
Workout: Brisk and Rhythmic Exercise  
The workout trains and conditions your heart, lungs, and muscles  
to operate more efficiently. Increase exercise in response to your  
heart rate to train and strengthen your cardiovascular system.  
Concentrate on exercising smoothly.  
Cool-Down: Slow and Relaxed Exercise  
Cooling down relaxes your muscles and gradually lowers your  
heart rate. Slowly reduce your workload until your heart rate is  
below 60 percent of your maximum heart rate. The cool down  
should last at least five minutes, followed by some light stretching  
to enhance your flexibility.  
Beginning a Fitness Program  
If you cannot sustain 12 continuous minutes in your target heart  
rate zone, exercise several times a day to get into the habit of  
exercising.  
Try to reach and maintain 60-65 percent of your maximum heart  
rate. Alternate exercise with periods of rest until you can sustain  
12 continuous minutes of exercise at 60-65 percent of your  
maximum heart rate.  
Begin exercising in three to five minute sessions.

Weight Management  
CHAPTER THIRTEEN: DESIGNING AN EXERCISE PROGRAM  
Consistent aerobic exercise will help you change your body  
composition by lowering your percentage of body fat. If weight  
loss is a goal, combine an increase in the length of your workouts  
with a moderate decrease in caloric intake. For weight control,  
how long and how often you exercise is more important than  
how hard you exercise.  
Managing  
Weight  
Exercise four to five times a week.  
Try to reach and maintain 60-75 percent of your  
maximum heart rate with moderate exercise.  
Exercise for 30-45 minutes at 60-65 percent of your target  
heart rate.  
Here are some tips to achieving your weight management goal:  
Consume most of your dietary calories at breakfast and  
lunch, and eat a light dinner. Do not eat close to bedtime.  
Exercise before meals. Moderate exercise will help  
suppress your appetite.  
Take exercise breaks throughout the day to help increase  
metabolism (calorie expenditure).

Keeping Your Bike Clean  
CHAPTER FIFTEEN: CARE AND MAINTENANCE  
Your CS 8.0 Bike doesn’t require any routine maintenance, not  
even lubrication. Keeping it clean is the most important task.  
How to  
Care for  
Your Bike  
After every workout: Perspiration should be wiped from the  
control console, contact heart rate pads, shrouds, and seat.  
Weekly: Wipe down your CS 8.0 Bike once a week with a water-  
dampened soft cloth. On the contact heart rate pads, use a  
glass cleaning solution. Be careful not to get excessive moisture  
between the edge of the overlay panel and the console, as this  
might create an electrical hazard or cause the electronics to fail.  
Expert service and maintenance at a reasonable cost are available  
through your factory-trained, authorized True Fitness dealer. The  
dealer maintains a stock of repair and replacement parts and has  
the technical knowledge to meet your service needs.

Physician  
Robert Robergs, editor of the prestigious Journal of Exercise  
Physiology, conducted a study in 2002 of the maximal heart rate  
equation 220 - age. He found this equation “has no scientific  
merit for use in exercise physiology and related fields.”  
A New  
HRmax  
Equation  
In his survey of research in this area, Robergs found several other  
simple equations that were significantly more accurate. The best  
equation he found was derived in 1994 by Oten Inbar:  
205.8 - (0.685 * age)  
The CS 8.0 console uses the Inbar equation. Even though this is  
the best available equation, it still has a possible range of error of  
+/- 6 beats per minute.  
Other similar equations that are also more accurate than 220 - age  
are:  
206.3 - (0.711 * age) (Londeree, 1982)  
206.0 - (0.700 * age) (Tanaka, 2001)  
208.8 - (0.734 * age) (Robergs meta study, 2002)

Maximal Oxygen Uptake and METs

Appendix B  
Maximal oxygen uptake, or VO max, is considered the best single  
measurement of cardiovascular2fitness. It represents the peak rate  
of your body’s oxygen consumption capability, which is important  
because this is one of the two biggest factors in endurance  
performance.  
VO2  
(The other big endurance factor is the lactate threshold, which  
is the exercise level at which blood lactate begins to accumulate  
above resting levels. The lactate threshold is much more difficult  
to measure than VO2max, which is why VO2max is the accepted  
standard.)  
The only accurate way to measure VO2max is to use a laboratory-  
grade respiratory diagnostic system during a maximal exercise  
test. All other methods produce an estimate with varying degrees  
of accuracy.  
Serious training results in an average improvement in VO2max  
of 20%, and all this takes place in 8 to 12 weeks. Additional  
performance improvement after this time is a result of a higher  
lactate threshold and, to a lesser degree, increased biomechanical  
efficiency.  
(See Wilmore & Costill, Physiology of Sport and Exercise, pages  
140-141, and ACSM Guidelines, page 68).  
VO max is expressed in milliters of oxygen per minute per  
kilo2gram of body weight, or ml/min/kg.

METs are defined as the ratio of the current body energy  
expenditure rate compared with basal metabolic rate (BMR):  
MET  
Explanation  
METs = (VO2 rate of current state) / 3.5  
where 3.5 represents BMR. VO2 (oxygen uptake) and 3.5 are in  
units of ml/kg/minute of oxygen consumed by the body. This  
oxygen consumption rate corresponds to about 72 calories per  
hour for a 150-pound person.

Details on How the CS 8.0 Bike  
Controls Your Exercise Intensity  
97  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix C  
As you ride the CS 8.0 Bike, your exercise intensity is best  
measured as the amount of power received by the bike from your  
pedaling. This power is usually expressed in watts. The watts  
measurement is calculated from your pedaling speed (called  
cadence) multiplied by the amount of resistance on the pedals  
(called torque). (See Feynman, Lectures on Physics, 1971.)  
Constant  
Power &  
Constant  
Torque  
In most cases it is desirable to keep the exercise intensity  
constant, no matter what the pedal cadence, since it allows  
accurate control of the rider’s workout. This kind of workload  
control is called constant power. If you pedal faster, the resistance  
on the pedals (torque) is reduced by the same amount. If you  
pedal slower, the resistance is increased.  
If, instead, the amount of resistance on the pedals stays the  
same when your cadence changes, your workload intensity will  
vary directly with your cadence. If you pedal twice as fast, your  
exercise intensity doubles. This kind of workload control is called  
constant torque.  
Constant power is used by the CS 8.0 Bike in most cases, in order  
to provide the most accurate workload control. This is especially  
important in heart rate control workouts and the Calorie Goal  
program.  
A negative side-effect of constant power is that at very low  
cadences, such as below 55 rpm, the amount of extra torque  
applied to the pedals to keep power constant is so great that  
the rider may not be able to keep the pedals moving. To reduce  
this problem, the bike changes to constant torque at cadences  
below 55 rpm, preventing any further increases in torque. The  
computer will also warn you that it is no longer able to control  
exercise intensity.  
98  
CS 8.0 Owner’s Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix C  
Constant torque is used in a modified way in Bike Mode. In  
addition to constant resistance for a given “gear,” additional torque  
is applied to simulate wind and road resistance, as well as to  
compensate for different body weights.  
Personal Power was initially designed to vary workload at a  
1:1 ratio with body weight, just like a METs-based exercise  
prescription. However, it turns out that human endurance and  
power generating capability varies with the 2/3 root of body  
weight, not straight body weight. This relationship can be seen in  
everything from weightlifting world records to distance running  
competitions. (See McMahon and Bonner, On Size and Life  
(1985), page 55).  
The  
Personal  
Power  
Calculation  
Since METs do not work the way they’re supposed to, Personal  
Power is based on a new unit of measure that correctly accounts  
for body weight. This new unit of metabolic measure, called the  
T-MET, is defined as:  
T-MET = watts / (kg) 2/3  
where watts is power applied to an external machine from the  
exerciser, and kg is the exerciser’s body weight in kilograms.

Appendix D  
In 1998, the American College of Sports Medicine completed  
their most important position stand, titled, “The recommended  
quantity and quality of exercise for developing and maintaining  
cardiorespiratory and muscular fitness in healthy adults.” The  
ACSM is recognized as the premier authority in this area, so  
this document describes the current consensus among exercise  
physiologists and coaches.  
Introduction  
(Also note that the ACSM is a fairly conservative body, so they  
only make recommendations when there are compelling reasons.)  
The following is a summary of the document. The full document  
can be found on the ACSM’s journal’s website:  
fulltext.htm>  
The variables of frequency, intensity, and duration of exercise  
quantify the degree of overload stimulus in an exercise program.  
In general, the greater the stimulus the greater the training  
effect. All three types of exercise (cardiovascular, resistance, and  
flexibility) should be included in a training program.  
Cardiovascular training is especially sensitive to frequency and  
intensity; the minimums for developing and maintaining fitness  
are at least ten minutes per day at a minimum of 50% VO2max at  
least two days per week. Proper warmup and cooldown, including  
flexibility, are recommended.  
102  
CS 8.0 Owner’s Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix D  
Training should be three to five days per week at between 55%  
and 90% maximum heart rate. Deconditioned individuals should  
stay between 55% and 64%. Total duration of training should be  
between 20 and 60 minutes, with the time varying inversely with  
intensity. High-intensity, short duration exercise is generally only  
recommended when training for non-athletic competition.  
Specific Advice  
For  
Cardio  
fitness and  
Body  
Composition  
Adequate exercise intensity requires the use of large muscle  
groups, which typically means legs and buttocks. In some cases,  
shoulders and upper back muscles used in rigorous swimming  
will be adequate.  
Resistance training should consist of one set of 8 to 10 exercises  
that stimulate all the major muscle groups, two to three days  
a week. Multiple sets will not necessarily provide greater  
benefits, especially considering the significantly increased time  
requirements and adherence difficulties.  
Specific Advice  
For Muscular  
Strength  
and Flexibility  
Flexibility exercises should stretch the major muscle groups a  
minimum of two to three times a week, and should include both  
static and dynamic techniques.
