Heart Rate Zones
CAUTION: Consult your
physician to specify heart rate
zones/targets that are appropriate
for your tness level and health
condition.
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
1–5 according to increasing intensity.
The Forerunner sets the heart rate
zone ranges (see the table on page
46) based on your maximum and
resting heart rates set in your user
prole (see page 33).
