program. Note: If you stop exercising, the time
mode will pause after a few seconds.
¥ DistanceÑThis mode shows the total distance you
have pedaled, up to 99.99 miles. The display will
then reset to zero and continue counting.
¥ Fat calories (FAT CALS)ÑThis mode shows the
approximate number of fat calories you have
burned. (See FAT BURNING on page 10 for an
explanation of fat calories.)
¥ Calories (CALS)ÑThis mode shows the approxi-
mate number of calories you have burned. (This
number includes both fat calories and carbohydrate
calories. See FAT BURNING on page 10.)
¥ ScanÑThis mode displays the calories, fat calories,
speed, time, and distance modes, for 5 seconds
each, in a repeating cycle.
HOW THE PACER PROGRAMS OPERATE
When you use a
pacer program,
two columns of
bars will appear in
the display. The
left column will
show a target
pace; the right
column will show
your actual
pedaling pace. The
Target Pace Actual Pace
target pace will change periodically during the
program; as the target pace changes, simply adjust
your pedaling pace to keep both columns at the same
height. Important: The target pace is a goal pace.
Your actual pace may be slower than the target
pace, especially during the first few months of
your exercise program. Be sure to exercise at a
pace that is comfortable for you.
DESCRIPTION OF THE CONSOLE
The innovative console offers a manual mode and
three pacer programs. The pacer programs are
designed to help you achieve specific exercise goals
by pacing your exercise. The programs include a
stamina-building Interval program, an Aerobic
program, and a special Fat Burn program. Whether
you select the manual mode or one of the three pacer
programs, the consoleÕs six monitor modes will
provide continuous exercise feedback during your
workouts.
The graphs at the bottom of the console show how the
target pace will change during the programs. Look at
the graphs for a moment (see the drawing at the left).
Each graph is divided into ten columns, with six bars in
each column. The columns represent two-minute time
periods, and the red bars show what the target pace
will be. In the first column of the Interval graph, for
example, there is one red bar. This shows that during
the first two minutes of the Interval program, the target
pace will be about 5 miles per hour (see the scale at
the left end of the graph). In the second column there
are five red bars. This shows that during the second
two-minute time period, the target pace will be about
25 miles per hour. Note: Because there are ten two-
minute periods, each program will last for twenty
minutes.
DESCRIPTION OF THE MONITOR MODES
¥ SpeedÑThis mode shows your pedaling pace, in
miles per hour.
¥ TimeÑIf you select the manual mode, this mode
will count up the length of time you have exercised.
If you select one of the three pacer programs, this
mode will count down the time remaining in the

to exercise at a pace that is comfortable for

CONDITIONING GUIDELINES
The following general guidelines will help you to plan
your exercise program. Remember that proper nutri-
tion and adequate rest are essential for successful
results.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle
number in your training zone as you exercise.
Aerobic Exercise
WARNING: Before beginning this or any exer-
cise program, consult your physician. This is
especially important for persons over the age
of 35 or persons with pre-existing health
problems.
If your goal is to strengthen your cardiovascular
system, your exercise must be Òaerobic.Ó Aerobic
exercise is activity that requires large amounts of
oxygen for prolonged periods of time. This increases
the demand on the heart to pump blood to the
muscles, and on the lungs to oxygenate the blood.
For aerobic exercise, adjust the intensity of your
exercise until your heart rate is near the highest
number in your training zone.
EXERCISE INTENSITY
Whether your goal is to burn fat or strengthen your
cardiovascular system, the key to achieving the
desired results is to exercise with the proper intensity.
The proper intensity level can be found by using your
heart rate as a guide. The chart below shows recom-
mended heart rates for fat burning, maximum fat
burning, and cardiovascular (aerobic) exercise.
HOW TO MEASURE YOUR HEART RATE
To measure your heart rate, first exercise for at least
four minutes. Then, stop exercising and place two
fingers on your
wrist as
shown. Take a
six-second
heartbeat
count, and
multiply the
result by 10 to
find your heart
rate. For
example,
if your six-
second heart-
beat count is 14, your heart rate is 140 beats per
minute. (A six-second count is used because your
heart rate will drop rapidly when you stop exercising.)
To find the proper heart rate for you, first find your age
near the top of the chart (ages are rounded off to the
nearest ten years). Next, look below your age and
find the three numbers in boxes. The three numbers
are your Òtraining zone.Ó The lowest number is the
recommended heart rate for fat burning; the middle
number is the recommended heart rate for maximum
fat burning; the highest number is the recommended
heart rate for aerobic exercise.
Adjust the intensity of your exercise until your heart
rate is at the desired level. You can adjust the inten-
sity of your exercise by changing your pedaling pace,
adjusting the pedaling resistance, or moving the
handlebars as you pedal.
Fat Burning
WORKOUT GUIDELINES
To burn fat effectively, you must exercise at a rela-
tively low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
uses easily accessible carbohydrate calories for
energy. Only after the first few minutes of exercise
does your body begin to use stored fat calories for
energy. If your goal is to burn fat, adjust the intensity
of your exercise until your heart rate is near the
lowest number in your training zone as you exercise.
Each workout should include the following three parts:
A warm-up, consisting of 5 to 10 minutes of stretch-
ing and light exercise. A proper warm-up increases
your body temperature, heart rate, and circulation in
preparation for strenuous exercise. (See
SUGGESTED STRETCHES on page 11.)
10
Download from Www.Somanuals.com. All Manuals Search And Download.
Training zone exercise, consisting of 20 to 30
minutes of exercise with your heart rate in your
training zone.
EXERCISE FREQUENCY
To maintain or improve your condition, plan three
workouts each week, with at least one day of rest
between workouts. After a few months of regular
A cool-down, with 5 to 10 minutes of stretching.
Thorough stretching helps to prevent problems caused exercise, you may complete up to five workouts each
when you stop exercising suddenly. Stretching for
increased flexibility is also most effective after exercis-
ing. A proper cool-down should leave you feeling
relaxed and comfortably tired.
week, if desired.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
SUGGESTED STRETCHES
1
The correct form for several basic stretches is shown in the
drawings below. Move slowly as you stretchÑnever bounce.
1. Toe Touch Stretch
Stand with your knees bent slightly and slowly bend forward

your back foot flat on the floor. Bend your front leg, lean for-
ward and move your hips toward the wall. Hold for 15 counts,
then relax. Repeat 3 times for each leg. To cause further
stretching of the achilles tendons, bend your back leg as well.
Stretches: Calves, achilles tendons, and ankles.

CRANK ADJUSTMENT
If the arms of the Crank (14) become loose, they
should be tightened in order to prevent excessive
wear. Loosen the crank nut on the left arm of the
Crank. Place the end of a standard screwdriver in one
of the slots in the slotted crank nut. Lightly tap the
