storage tray with space for items such as
water bottles, personal stereos, and cell phones.
Additionally, an integrated reading rack for
supporting a book or magazine (B) is located
below the workout profile window (M) in the main
console.
3. HEART RATE ZONE TRAINING EXERCISE 3.1 HEART
RATE ZONE TRAINING EXERCISE Research shows
that maintaining a specific heart rate while
exercising, is both the optimal way to monitor
the intensity of a workout and to achieve
maximum results. This is the concept behind a
heart rate zone training approach to exercise.
Zone Training identifies an exerciser's ideal
heart rate range, or zone, for burning fat or
increasing cardiovascular fitness. The values
within the zone depend on the workout. NOTE
Consultation with a fitness trainer is
recommended for defining specific fitness goals
and designing a suitable workout
program. The four bike workouts, Fat Burn,
Cardio, Target Interval, Target Hill are designed
to take full advantage of the benefits of a
heart rate program exercise
During these workouts, either grasp the pulse
system sensors, or wear a Polar heart rate chest
strap to enable the bikes on board computer to
monitor the heart rate. The computer automatically
adjusts the resistance level to maintain the
target heart rate based on the actual heart rate.
15
3.2 HEART RATE MONITORING 3.2.1 The hand grip
heart rate monitoring system The hand grip pulse
sensors are built into each side of the handle
bar grips. To check heart rate During a workout,
grasp of the two sensors that are set into the
handlebars. For an accurate reading, use a
comfortable grip. The console will display the
heart rate after 1 to 10 seconds.
3.2.2 The Polar telemetry heart rate monitoring
chest strap (Or similar compatible item) The bike
is equipped with Polar telemetry, a heart rate
monitoring system in which electrodes are pressed
against the skin, and transfer heart rate signals
to the bike console. These electrodes are mounted
in the chest strap that is worn during the
workout. The chest strap is an optional extra, to
order call your local distributor or
supplier. See the diagram below for correct
positioning of the strap. The electrodes (A)
which are the two grooved surfaces on the
underside of the strap, must remain moist to
transmit accurately the electrical impulses of
the heart back to the receiver. Moisten the
electrodes or apply a conductive gel. Secure the
strap as high under the chest muscles as
possible. The strap should be snug, but
comfortable enough to allow for normal breathing.
The transmitter strap delivers an optimal heart
rate reading when the electrodes are in direct
contact with skin. (It may also function through
a thin layer of wet clothing) If it becomes
necessary to remoisten the chest strap
electrodes, grasp the center of the strap, pull
it away from the chest and remoisten the two
electrodes.

4 THE WORKOUTS 4.1 WORKOUT OVERVIEWS This
section lists the Bikes preprogrammed workouts.
For more detailed information, see Section 4.2,
titled Using the Workouts. 4.1.1 Quick Start
This is the fastest way to begin exercising, and
it bypasses the steps involved in selecting a
specific workout program. After the Quick Start
key is pressed, a constant level workout
begins. All intensity levels are changed manually
they not change automatically.. 4.1.2 Manual
As Quick Start - this is a workout in which the
intensity levels are change manually.
4.1.3 Preset Program Interval is a Hill
workout in which intensity levels rise and fall.
The higher levels gradually incline toward a
peak and then gradually decline.
Hill is an interval training workout combining
hills and valleys with hills of different
intensity levels, and is proven to provide
effective, time efficient cardiovascular results.
17
4.1.3 Preset Program Cont.
Mountain is a Hill workout in which the
intensity levels gradually incline toward one
ultimate peak and then gradually decline.
Power is a Hill workout in which the intensity
level alternates between high and low levels
very quickly to simulate a typical speed-training
(interval) workout.
4.1.4 Heart Rate Program The user must wear a
Polar heart rate chest strap, or grasp the pulse
system sensors continuously.
Fat Burn This is a low intensity workout
for burning the bodys fat reserves. The workout
program automatically adjusts the intensity
level, based on the actual heart rate. The user
selects the intensity level from 50 to 65
percent of the theoretical maximum (MHR).
18

• Maximum Heart Rate (MHR) Defined by the
  American College of Sports Medicine's
• "Guidelines for Exercise Testing and
  Prescription" as equal to 220 minus an
  individuals age.
• Target Heart Rate (THR) This is a percentage
  of the theoretical maximum.
• For example, a 35 year old user's THR for
  the CARDIO workout is 148.
• This workout targets 80 percent of the
  maximum, so the equation would be 0.8(220-35)
  148.
• Programs that calculate a THR 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
• pulse system sensors and it uses this data
  to adjust the resistance. Manually raising the
  rate
• increases the intensity of the
  cardiovascular exercise.

• Cardio
• This is a higher intensity workout for more
  fit users, emphasizing cardiovascular benefits
  and
• maximum fat burning. The workout program
  automatically adjusts the intensity level, based
  on
• the actual heart rate. The user selects the
  intensity level from 70 to 80 percent of the
• theoretical maximum (MHR).

User example 35 years old (MHR 185) 80 MHR
19
Target Interval The workout consists of
three hills that target three heart rate goals.
The first hill brings the heart rate to 70
percent of MHR. The second hill increases the
rate to 75 percent of MHR. The third hill brings
the heart rate to 80 percent of MHR. The
valley always is defined as 65 percent of MHR.
User example For a 35 year old (MHR 185) 70,75
80
Target Hill This workout alternates
between two target heart rates as quickly as
possible. When setting up the workout, the
user enters a target maximum heart rate. After a
three minutes warm-up, the Intensity will
increase, until the user reaches the 85 percent
of MHR. Then, the intensity decreases, until
the heart rate falls to the 65 percent of MHR.
The program repeats these alternating
intensity levels.
User example 35 year old (MHR 185) 85 MHR,

4.3 FITNESS TEST The Fitness Test workout
measures cardiovascular fitness and can be used
to monitor improvements in endurance every four
to six weeks. The user must grasp the pulse
sensors when exercising or wear a heart rate
chest strap, as the test score calculation is
based on a heart rate reading. The workout
consist of three steps, 2 minutes warming up, 6
minutes workout, 2 minutes cool down. The
Fitness Test is considered to be a sub-max VO2
(volume of oxygen) test. It gauges how well the
heart supplies oxygenated blood to the exercising
muscles, and how efficiently those muscles
receive oxygen from the blood. Physicians and
exercise physiologists generally regard this
test as a good measure of aerobic capacity.
Please note that the estimated VO2 max scores
achieved will be 10 percent to15 percent lower on
stationary exercise bikes than those achieved on
treadmill. Stationary cycling has a higher rate
of isolated muscle fatigue of the quadriceps when
compared to walking/running on a treadmill,
climbing on a stair climber, or utilizing a
cross-trainer. This higher rate of fatigue
corresponds to lower levels of estimated VO2 max
scores. 4.3.1 To set up the Fitness Test -
Press the Fitness Test. - Enter the users age
and gender as the monitors message. - The
message center displays the prompt, DO YOU
EXERCISE 3 TIME PER WEEK DURING LAST 3
MONTHS? 1. CONDITIONS 2.UNCONDITIONS
Select 1. or 2. - Enter the uses weight. - The
console commences the workout. - The console
will read the user's heart rate, calculate a
fitness score, and display the score in the
MESSAGE CENTER. Note To receive a proper Fit
Test score, the work must be done within a
training zone. That is 40/60 RPM
(average 50 RPM) pedaling. The message center
displays RPM, and the workout profile
displays shapes, made of columns of lights, that
represent the range of RPM.
26
After the ten minutes, Fitness Test is completed
and a Fitness Test score will be displayed. The
console will not accept - Heart rates less
than 52 or greater than 200 beats per minute -
Body weights less than 75 pounds (34 kg) or
greater than 400 pounds (182 kg) - Ages below 10
or over 99 years - Input data that exceeds human
ability. 4.3.2 Important measuring
instructions It is important to take the
Fitness Test under similar circumstances each
time. The heart rate is dependent on many
factors, including - Amount of sleep on the
previous night at least seven hours is
recommended - Time of a day - Time you last ate
two to four hours after the last meal is
recommended - Time since you last drank a liquid
containing caffeine or alcohol, or smoked a
cigarette at least four hours is
recommended - Time since you last exercised at
least six hours is recommended For the most

6.3 TROUBLESHOOTING THE POLAR HEART RATE CHEST
STRAP HEART RATE READING IS ERRATIC OR ABSENT
ENTIRELY - Repeat the electrode moistening
procedure. The electrodes must remain wet
to pick up and transmit accurate heart rate
readings. - Make sure the electrodes are flat
against the skin. - Wash the belt transmitter
regularly with mild soap and water. - Make sure
the chest strap transmitter is within three feet,
or one meter, of the heart rate receiver.
- The chest strap is battery-operated and will
stop functioning when the battery runs out.
Contact JNB SPORTS or your Distributor for
instructions on how to have the chest strap
replaced. HEART RATE READING IS ERRATIC
OR EXTREMELY HIGH If the chest strap is worn
near sources of electromagnetic signals, these
signals may be strong enough to affect heart
rate readings. Possible sources include -
Television sets and/or antennas, cell phones,
computers, cars, high voltage power lines
and motor driven exercise equipment. - Another
heart rate transmitter within three feet, or one
meter, may also cause abnormal heart rate
readings. 6.4 TROUBLESHOOTING THE PULSE SYSTEM
SENSORS If the heart rate reading is erratic or
missing, do the following - Dry moist hands to
prevent slipping. - Apply hands to both
sensors, one in each hand. - Grasp the sensors
firmly. - Apply constant pressure around the
sensors. 6.5 RECYCLING THE BATTERY When this
