SUUNTO T1C User Guide - Manual (Page 23)

NOTE: The heart rate limits are displayed with dashes on the left outer rim of the display
if the limits are activated.
Possible real life situation: Staying in the zone
You want to have a good, tough training session today, so you set your heart rate limits to
equal your Zone 3 limits and turn the heart rate limit alarm on. Your Suunto heart rate
monitor notifies you when you go too slow, or push too hard!
5.2 Heart rate zones
Training with heart rate monitors is traditionally based on heart rate zones. The intensity
of your training is determined by the time you spend in each of three 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.
