Monitoring Your Heart Rate  
To obtain the greatest cardiovascular benefits from your exercise workout, it is important to  
work within your target heart rate zone. The American Heart Association (AHA) defines this  
target as 60%-75% percent of your maximum heart rate.  
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 tar-  
get heart rate zone is 60%-75% of 180 or 108-135 bpm. See Fitness Safety below.  
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.  
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%.  
According to the AHA, exercising above 75% of your maximum heart rate may be too stren-  
uous unless you are in top physical 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.  
Fitness Safety  
The target heart rate chart indicates average rate zones for different ages. A variety of differ-  
ent 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 profes-  
sional can help you determine the exercise intensity that is appropriate for your age and  
condition.  
10  
 
(MHR) = Maximum Heart Rate  
(THR) = Target Heart Rate  
220 - age = maximum heart rate (MHR).  
MHR x .60 = 60% of your maximum heart rate.  
MHR x .75 = 75% of your maximum heart rate.  
For example, if you are 30 years old, your calculations will be as follows:  
220 - 30 = 190  
190 x .60 = 114 (low end or 60% of MHR)  
190 x .75 = 142 (high end or 75% of MHR)  
30 year-old (THR) Target Heart Rate would be 114-142.  
See Table for additional calculations.
