DESCRIPTION OF THE CONSOLE
pace. Your actual pace may be slower than the tar-
get pace, especially during the first few months of
your exercise program. Be sure to exercise at a
pace that is comfortable for you.
The innovative console offers a manual mode and
three pacer programs. The pacer programs are
designed to help you achieve your exercise goals by
pacing your exercise. The programs include an 18
MPH/90 RPM program, a 12 MPH/60 RPM program,
and a 6 MPH/30 RPM program. The console also fea-
tures five monitor modes that provide continuous exer-
cise feedback. Note: On some consoles the pro-
grams are listed in MPH and on others in RPM.
Both sets of programs are identical.
The graphs on the left side of the console show how
the target pace will change during each program (see
the drawing above). Each graph is divided into ten
columns, and each column represents 1/10 of a mile.
The bars in each column show what the target pace
will be during that 1/10 of a mile. For example, in the
first column of the 12 MPH/60 RPM graph, there is
one bar. This shows that during the first 1/10 of a mile
in this program, the target pace will be 6 MPH (30
RPM). In the second column, there are two bars, indi-
cating that the pace is now 12 MPH (60 RPM)
HOW THE PACER PROGRAMS OPERATE
When you use a
pacer program, an
indicator will light
on each track of
the P.A.C.E.R.
display. The outer
track shows a tar-
get pace; the inner
track will show

will move around the track at the programmed
pace. As you exercise, adjust your pace so that
the indicators on the inner and outer tracks
remain even. As the program progresses, the tar-
get pace will change periodically; as the target
pace changes, you should also adjust your pace.
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.

CONDITIONING GUIDELINES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition and
adequate rest are essential for successful results.
During the first few months of your exercise program,
keep your heart rate near the low end of your training
zone as you exercise. After a few months of regular
exercise, your heart rate can be increased gradually
until it is near the middle of your training zone as you
exercise.
WARNING: Before beginning this or any
exercise program, consult your physician.
This is especially important for individuals
over the age of 35 or individuals withpre-
existing health problems.
To measure your heart rate, use the pulse sensor in
the handlebar. You can also measure your pulse by
placing two fingers
on your wrist. Stop
exercising and
WHY EXERCISE?
take a six-second
heartbeat count.
Exercise has proven essential for good health and
general well-being. Regular participation in a well-
rounded exercise program results in a stronger and
more efficient heart, improved respiratory function,
increased stamina and endurance, better weight man-
agement and body fat control, increased ability to deal
with stress, and greater self-esteem and confidence.
Multiply the result
by ten to find your
heart rate. (A six-
second count is
used because
your heart rate
drops quickly
when you stop
EXERCISE INTENSITY
exercising.) If your heart rate is too high, decrease the
intensity of your exercise. If your heart rate is too low,
increase the intensity of your exercise.
To maximize the benefits of exercising, it is important
to exercise with the proper intensity. The proper inten-
sity level can be found by using your heart rate as a
guide. For effective aerobic exercise, your heart rate
should be maintained at a level between 70% and
85% of your maximum heart rate as you exercise.
This is known as your training zone. You can find
your training zone in the table below. Training zones
are listed according to age and physical condition.
WORKOUT GUIDELINES
A well-rounded workout includes the following three
phases:
A warm-up phase, lasting 5 to 10 minutes. Begin with
slow, controlled stretches, and progress to more rhyth-
mic stretches. This will increase the body temperature,
heart rate, and circulation in preparation for strenuous
exercise.

A cool-down phase, consisting of 5 to 10 minutes of
stretching. Thorough stretching offsets muscle con-
tractions and other problems caused when you stop
exercising suddenly. Stretching for increased flexibility
is often most effective during this phase. This phase
should leave you relaxed and comfortably tired.
To maintain or improve your condition, complete three
workouts each week, with at least one day of rest
between workouts. After a few months of regular exer-
cise, you may complete up to five workouts each
week, if desired. Find the best time of day for your
workouts, and then stick with it.
Remember, the key to success is to make exercise a
regular and enjoyable part of your everyday life.
