MAINTENANCE AND TROUBLE-SHOOTING
Inspect and tighten all parts of the exercise cycle reg-
ularly. Replace any worn parts immediately.
The exercise cycle can be cleaned with a soft, damp
cloth. Avoid spilling liquid on the console. Keep the
console out of direct sunlight or the display may be
damaged. Remove the batteries when storing the
exercise cycle.
BATTERY REPLACEMENT
If the console does not function properly, the batteries
should be replaced. See assembly step 4 on page 5.
In addition, make sure that the console wire is
plugged into the console.
HOW TO TIGHTEN THE CRANK
If the arms of
the crank
become
loose, they
should be
tightened in
order to pre-
vent exces-
sive wear.
Loosen the
crank nut on
the left arm of
the crank.

Crank Arm
Slotted
Nut
Place the end of a standard screwdriver in one of the
slots in the slotted crank nut. Lightly tap the screw-
driver with a hammer to turn the slotted crank nut
counterclockwise until the arms are no longer loose.
Do not overtighten the slotted crank nut. When the
slotted crank nut is properly tightened, retighten the
crank nut.
HOW TO ADJUST THE RESISTANCE STRAP
If there is not enough pedaling resistance when the
resistance knob is turned to the highest setting, the
resistance strap may need to be adjusted. To adjust
the resistance
strap, first turn
the resistance
knob to the
lowest setting.
Next, locate
the slotted tab

the exercise
cycle. Grip the

strap underneath the slotted tab and pull it towards
the slot. When a little slack is created, pull the end of
the resistance strap tight and then let go of the strap.
Turn the crank for a moment to make sure that there
is not too much resistance.
HOW TO ADJUST THE CHAIN
The exercise cycle features a chain that must be kept
properly adjusted. If the chain causes excessive noise
or slips as you pedal, the chain should be adjusted.
To tighten the
chain, loosen,
but do not
remove, the
axle nuts on
both sides of
the flywheel.
Pull the fly-
wheel slightly Nut
forwards.
Make sure that
the flywheel is
straight and tighten the axle nuts.

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.
cise program, consult your physician, This is
especially important for persons over the age
EXERCISE INTENSITY
Whether your goal is to burn fat or to 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.
BPM HEART RATE TRAiNiNG ZONES
|
Age 20 30 40 50 60 70 80
To find the proper heart rate for you, first find your age
on the bottom of the chart (ages are rounded off to
the nearest ten years). Next, find the three numbers
above your age. The three numbers are your "training
zone." The lowest number is the recommended heart
rate for fat burning; the middle number is the heart
rate for maximum fat burning; the highest number is
the heart rate for aerobic exercise.
Burning Fat
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 ener-
gy. 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 num-
ber in your training zone as you exercise.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle num-
ber in your training zone as you exercise.
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be "aerobic." Aerobic exer-
cise 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.
HOW TO MEASURE YOUR HEART RATE
To measure your J
heart rate, first I
exercise for at
least four minutes.
Then, stop exercis-
ing 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 heartbeat 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.)
WORKOUT GUIDELINES
Each workout should include the following three
important 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 exercise.
Training zone exercise, consisting of 20 to 30 min-
utes of exercising with your heart rate in your training
zone. (During the first few weeks of your exercise pro-
gram, do not keep your heart rate in your training
zone for longer than 20 minutes.)
9

A cool-down, with 5 to 10 minutes of stretching. This
will increase the flexibility of your muscles and will
help to prevent post-exercise problems.
EXERCISE FREQUENCY
To maintain or improve your condition, plan three work-
outs each week, with at least one day of rest between
workouts. After a few months of regular exercise, you
may complete up to five workouts each week, if
desired. Caution: Be sure to progress at your own
pace and avoid overdoing it. Incorrect or excessive
training may result in injury to your health.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
