the end of the program you will receive a Fit Test Score which is the equiva-  
lent of your approximate VO2 max. This number should be used as a refer-  
ence to gauge aerobic improvements over an extended workout protocol.  
Please use the following table for reference only:

Your maximum heart rate may be roughly calculated by  
subtracting your age from 220. Your maximum heart rate and  
aerobic capacity naturally decreases as you age. This may vary  
from one person to another, but use this number to find your  
approximate effective target zone. For example, the maximum  
heart rate for an average 40 year-old is 180 bpm. The target  
heart rate zone is 60%-75% of 180 or 108-135 bpm. See Fitness  
Safety on page 22.

Before beginning your workout, check your normal resting  
heart rate. Place your fingers lightly against your neck, or against  
your wrist over the main artery. After finding your pulse, count  
the number of beats in 10 seconds. Multiply the number of beats  
by six to determine your pulse rate per minute. We recommend  
taking your heart rate at these times; at rest, after warming up,  
during your workout and two minutes into your cool down, to  
accurately track your progress as it relates to better fitness.  
F. RESULT MODE  
1. When operation time is finished, the console is in  
“Result state”, (W1) displays the following data in  
4 second intervals.  
a. Total operation time.  
b. Cumulative calories.  
c. Cumulative distance.  
d. Average speed.  
e. Average RPM.  
2. W3 displays “average heart rate”  
3. W2 displays “RESULTS MODE” and shows profiles  
of every program for 2.5 seconds sequentially, except in  
“FITNESS TEST” program.  
During your first several months of exercising, the AHA  
recommends aiming for the lower part of the target heart rate  
zone- 60%, then gradually progressing up to 75%.  
4. W2 displays “SCORE=000” when “FITNESS TEST”  
According to the AHA, exercising above 75% of your maxi-  
mum heart rate may be too strenuous unless you are in top physi-  
cal condition. Exercising below 60% of your maximum will result  
in minimal cardiovascular conditioning.

Check your pulse recovery rate – If your pulse is over 100 bpm  
five minutes after you stop exercising, or if it’s higher than  
normal the morning after exercising, your exertion may have been  
too strenuous for your current fitness level. Rest and reduce the  
intensity next time.

The target heart rate chart indicates average rate zones for different  
ages. A variety of different factors (including medication, emotional  
state, temperature and other conditions) can affect the target heart rate  
zone that is best for you. Your physician or health care professional can  
help you determine the exercise intensity that is appropriate for your  
age and condition.

For a 30 year-old the (THR) Target Heart Rate  
would be 114-142.
