Many athletes are using heart rate
zones to measure and increase their
cardiovascular strength and improve
their level of tness. A heart rate zone
is a set range of heartbeats per minute.
The ve commonly accepted heart
rate zones are numbered from 1 to
5 according to increasing intensity.
Generally, heart rate zones are
calculated based on percentages of
your maximum heart rate.

Knowing your heart rate zones can
help you measure and improve your
tness by understanding and applying
these principles.
• Your heart rate is a good measure of
exercise intensity.
• Training in certain heart rate
zones can help you improve
cardiovascular capacity and
strength.
• Knowing your heart rate zones can
prevent you from overtraining and
can decrease your risk of injury.
If you know your maximum heart
rate, you can use the table (page 25) to
determine the best heart rate zone for
your tness objectives.
If you do not know your maximum
heart rate, use one of the calculators
available on the Internet. Some gyms
and health centers can provide a test
that measures maximum heart rate.
