Target Heart Rate Zone - Keys Fitness Alliance 920R Owner's Manual

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 aver-
age 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.
(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 on right for additional calculations.
