SUUNTO M4 - Manual (Page 25)

When ready, Suunto M4 calculates your fitness index (scale 0 - 10) and shows
your current fitness level:
very poor = 0 - 1.9
below average = 2 - 3.9
fair = 4 - 4.9
good = 5.0 - 5.9
very good = 6.0 - 6.9
excellent = 7.0 - 10.0
NOTE: If you are using a guided exercise program, the fitness test is considered
an exercise and affects the target completion.
TIP: Compare your results with your previous fitness test results in history &
trend, see Section 13.2 History & trend on page 28.
TIP: Perform the fitness test regularly, for example once a month, to keep your
fitness level updated.
12.2 Testing your rest HR
Rest HR is your HR at rest. Test your rest HR to get even more personalized
guidance from Suunto M4 and to follow the development of your fitness level.
Improving fitness level usually lowers the rest HR.
To test your rest HR:
1. Moisten the contact areas and put on the HR belt.
