end of the Resistance Strap (17) and pull it back
slightly to remove any slack. While holding the end of
the Resistance Strap, fully close the Strap Buckle.
Turn the crank for a moment to make sure that there
is not too much resistance.

If the console does not display correct feedback, the
reed switch should be adjusted. In order to adjust the
reed switch, the Left Side Shield (12) must be removed. Remove the four Side Shield Screws (15) from the
Right Side Shield (13) and the three M4 x 16mm
Tapping Screws (30) from the bottom of the Left Side
Shield. Carefully slide the Left Side Shield forward off
the arm of the Crank (20) and remove it.

HOW TO ADJUST THE DRIVE BELT
The exercise cycle features a drive belt that must be
kept properly adjusted. If the belt causes excessive
noise or slips as you pedal, the belt should be
checked. To do this, the side shields must first be
removed. Refer to the instructions on this page and
remove the left side shield. Next, remove the right
side shield the same way.

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.

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 number in your training zone as you exercise.

WARNING:

Before beginning this
or any exercise program, consult your physician. This is especially important for persons
over the age of 35 or persons with pre-existing health problems.

Aerobic Exercise
If your goal is to strengthen your cardiovascular system, your exercise must be “aerobic.” 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 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 recommended heart rates for fat burning, maximum fat

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 heartbeat count
is 14, your heart rate is 140 beats per minute. (A sixsecond count is used because your heart rate will
drop rapidly when you stop exercising.)

burning, and cardiovascular (aerobic) exercise.
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.

WORKOUT GUIDELINES
Each workout should include the following three parts:
A warm-up, consisting of 5 to 10 minutes of stretching and light exercise. A proper warm-up increases
your body temperature, heart rate, and circulation in
preparation for exercise.

Burning Fat
Training zone exercise, consisting of 20 to 30 minutes of exercising with your heart rate in your training
zone. (During the first few weeks of your exercise program, do not keep your heart rate in your training
zone for longer than 20 minutes.)

To burn fat effectively, you must exercise at a relatively 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 num-

will increase the flexibility of your muscles and will
help to prevent post-exercise problems.

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.

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 exercise, you
may complete up to five workouts each week, if

Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
