HOW TO USE THE HEALTHRIDER¨MOMENTUM
PLUGGING IN THE POWER CORD
Plug the power
cord into a 120-volt
outlet. The displays
and indicators on
the console will
flash once; the dis-
plays and various
indicators will then
light and a tone will
sound. Please
read through all instructions in this section before
using the MOMENTUM.
HOW TO EXERCISE ON THE MOMENTUM
To mount the MOMENTUM, hold the handlebars and
step onto the pedal that is in the lowest position. Next,
step onto the other pedal. Push the pedals until they
begin to move with a continuous motion. Note: The
pedal disks can turn in either direction. It is rec-
ommended that you move the pedals disks in the
direction shown below; however, to give variety to
your exercise, you may choose to turn the pedal
disks in the opposite direction.
To dismount the MOMENTUM, wait until the pedals
come to a complete stop. CAUTION: The MOMEN-
TUM does not have a freewheel; the pedals will
continue to move until the flywheel stops. When
the pedals are stationary, step off the highest pedal
first. Then, step off the lowest pedal.
INCLINE ADJUSTMENT
The incline frame can be raised or lowered to vary the
intensity of your exercise. To raise the incline frame,
lift the end of the incline frame until the crossbar is
resting on top of the incline bracket. Make sure that
the incline frame is resting securely on top of the
incline bracket. To lower the incline frame, first lift
the incline frame slightly. Then, push the incline brack-
et toward the upright and lower the incline frame onto
the stabilizer.
HOW TO USE THE UPPER BODY ARMS
The upper body arms are designed to give you a total
body workout. As you exercise, move the upper body
arms forward and back in order to work your arms,
back, and shoulders.
To vary the intensity of your upper body exercise, the
resistance of the upper body arms can be adjusted.
To increase the resistance, turn the arm resistance
knob clockwise; to decrease the resistance, turn the
knob counterclockwise.

The following guidelines will help you to plan your
exercise program. Remember that a proper diet and
adequate rest are essential for successful results.
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. For effective 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 physi-
cal condition.
Burning Fat
To burn fat, you must exercise at a 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 low end of your training zone as you exercise.
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, 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 middle of your training zone.
HOW TO MEASURE YOUR HEART RATE
To measure your
heart rate, stop
exercising and
place two fingers
on your wrist as
shown. Take a
six-second
heartbeat count,
and multiply the
result by ten to
find your heart
rate. (A six-sec-
ond count is used because your heart rate drops
quickly when you stop 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.
WORKOUT GUIDELINES
Each workout should include three important parts:
(1) a warm-up, (2) training zone exercise, and (3) a
cool-down.
Warming up
Warming up prepares the body for exercise by
increasing circulation, delivering more oxygen to the
muscles, and raising the body temperature. Begin
each workout with 5 to 10 minutes of stretching and
light exercise to warm up.

SUGGESTED STRETCHES
The correct form for several basic stretches is shown at the
right. Move slowly as you stretchÑnever bounce.
1. Toe Touch Stretch
Stand with your knees bent slightly and slowly bend forward
from your hips. Allow your back and shoulders to relax as you
reach down toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times. Stretches: Hamstrings,
back of knees and back.
2. Hamstring Stretch
Sit with one leg extended. Bring the sole of the opposite foot
toward you and rest it against the inner thigh of your extended
leg. Reach toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times for each leg. Stretches:
Hamstrings, lower back and groin.
3. Calf/Achilles Stretch
With one leg in front of the other, reach forward and place
your hands against a wall. Keep your back leg straight and
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.
4. Quadriceps Stretch
With one hand against a wall for balance, reach back and
grasp one foot with your other hand. Bring your heel as close
to your buttocks as possible. Hold for 15 counts, then relax.
Repeat 3 times for each leg. Stretches: Quadriceps and hip
muscles.
5. Inner Thigh Stretch
Sit with the soles of your feet together and your knees out-
ward. Pull your feet toward your groin area as far as possible.
Hold for 15 counts, then relax. Repeat 3 times. Stretches:
Quadriceps and hip muscles.

Training Zone Exercise
After warming up, increase the intensity of your exer-
cise until your heart rate is in your training zone for 20
to 30 minutes.
Cooling Down
Finish each workout with 5 to 10 minutes of stretching.
Stretching after exercise develops flexibility and helps
prevent post-exercise problems. A proper cool-down
should leave you feeling relaxed and comfortably tired.
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 exer-
cise, you may complete up to five workouts each
week, if desired.
