Monitoring Your Heart Rate
(MHR) = Maximum Heart Rate
(THR) = Target Heart Rate
220 - age = maximum heart rate (MHZ)
MHZ x .60 = 60% of your maximum heart rate.
MHZ 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 MHZ)
190 x .75 = 142 (high end or 75% of MHZ)
30 year-old (THR) Target Heart Rate would be 114-142
See Heart Rate Table (on next page) for additional calculations.
Fitness Safety 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.
