3.6.2 Heart rate zones
Heart rate zones are defined as percentages of your maximum heart rate. Zone training
is an established training method, so there are pre-set defaults as follows:
● Zone 1 (60-70%): fitness zone; improves basic fitness and is good for weight
control.
● Zone 2 (70-80%): aerobic zone; improves aerobic fitness and is good for
endurance training.
● Zone 3 (80-90%): threshold zone; improves aerobic and anaerobic capacity and
is good for improving peak performance.
If you are following a personal training program that uses zone training, enter the values
defined by the program.
NOTE: The zone defaults follow the guidelines of the American College of Sports Medicine
for exercise prescription.
In the HR ZONES menu, you can turn on the zone feature, define zone limits, and turn
tones on or off. When the zones feature and the tones are turned on, your device alerts
you with a beep when you move from one zone to another.
