ment of the program, both the Current Segment  
column and the column to the right will flash, a  
series of tones will sound, and all resistance set-  
tings will move one column to the left. The resis-  
tance setting for the second segment will then be  
shown in the flashing Current Segment column,  
and the resistance of the pedals will change to the  
resistance setting for the second segment. Note: If

Both heart rate programs—As you pedal, the  
console will regularly compare your heart rate to  
the target heart rate setting. If your heart rate is  
too far below or above the target heart rate set-  
ting, the resistance of the pedals will automatical-  
ly increase or decrease to bring your heart rate  
closer to the target heart rate setting.  
When you are finished exercising, the console

ularly. Replace any worn parts immediately.  
HANDGRIP PULSE SENSOR TROUBLESHOOTING  
If the handgrip pulse sensor does not function properly,  
see step 5 on page 11.  
To clean the exercise cycle, use a damp cloth and a  
small amount of mild soap. Important: To avoid  
damage to the console, keep liquids away from  
the console and keep the console out of direct  
sunlight.  
HOW TO MOVE THE EXERCISE CYCLE

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 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 maxi-  
mum 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  
The pulse sensor is not a medical device.  
Various factors may affect the accuracy of  
heart rate readings. The pulse sensor is  
intended only as an exercise aid in determin-  
ing heart rate trends in general.  
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.  
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.  
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 prepa-  
ration for exercise.  
Training zone exercise, consisting of 20 to 30 min-  
utes of exercising with your heart rate in your training  
zone. Note: During the first few weeks of your exer-  
cise program, do not keep your heart rate in your  
training zone for longer than 20 minutes.  
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.  
To find the proper heart rate for you, first find your age  
at 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 recommended  
heart rate for maximum fat burning; the highest num-  
ber is the recommended heart rate for aerobic exer-  
cise.  
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. Remember, the key to success is make exer-  
cise a regular and enjoyable part of your everyday life.  
Fat Burning  
To burn fat effectively, you must exercise at a relative-  
ly low intensity level for a sustained period of time.
