User Manual

of cardiovascular conditioning training should be performed within this zone. Improving basic
fitness builds a foundation for other exercise and prepares your system for more energetic
activity. Long duration workouts at this zone consume a lot of energy, especially from your
body’s stored fat.
Zone 3: Hard
Exercising at zone 3 begins to be quite energetic and feels like pretty hard going. It will
improve your ability to move quickly and economically. In this zone, lactic acid begins to form
in your system, but your body is still able to completely
flush it out. You should train at this
intensity at most a couple of times per week, as it puts your body under a lot of stress.
Zone 4: Very hard
Exercising at zone 4 will prepare your system for competition type events and high speeds.
Workouts in this zone can be performed either at constant speed or as interval training
(combinations of shorter training phases with intermittent breaks). High-intensity training
develops your
fitness level quickly and eectively, but done too often or at too high intensity
may lead to overtraining, which may force you to take a long break from your training
program.
Zone 5: Maximal
When your heart rate during a workout reaches zone 5, the training will feel extremely hard.
Lactic acid will build up in your system much faster than it can be removed, and you will be
forced to stop after a few minutes at most. Athletes include these maximum-intensity
workouts in their training program in a very controlled manner,
fitness enthusiasts do not
require them at all.
3.19.1. Heart rate zones
Heart rate zones are
defined as percentage ranges based on your maximum heart rate (max
HR).
By default, your max HR is calculated using the standard equation: 220 - your age. If you
know your exact max HR, you should adjust the default value accordingly.
Suunto 9 has default and
activity-specific HR zones. The default zones can be used for all
activities, but for more advanced training, you can use specific HR zones for running and
cycling activities.

Set your maximum HR from the settings under Training » Intensity zones » Default zones.
1. Tap the max HR (highest value, bpm) or press the middle button.
2. Select your new max HR by swiping up or down or by pressing the upper right or lower
right buttons.
