Using intensity zones for exercising helps guide your fitness development. Each intensity zone stresses your body in different ways, leading to different effects on your physical fitness. There are five different zones, numbered 1 (lowest) to 5 (highest), defined as percentage ranges based on your maximum heart rate (max HR), pace or power.
It is important to train with intensity in mind and understand how that intensity should feel. And don't forget, regardless of your planned training, that you should always take time to warm up before an exercise.
The five different intensity zones used in Suunto Spartan Sport Wrist HR Baro are:
Zone 1: Easy
Exercising in zone 1 is relatively easy on your body. When it comes to fitness training, intensity this low is significant mainly in restorative training and improving your basic fitness when you are just beginning to exercise, or after a long break. Everyday exercise – walking, climbing stairs, cycling to work, etc. – is usually performed within this intensity zone.
Zone 2: Moderate
Exercising at zone 2 improves your basic fitness level effectively. Exercising at this intensity feels easy, but workouts with a long duration can have a very high training effect. The majority 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 effectively, 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 dozen 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.
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 Spartan Sport Wrist HR Baro 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.

When you record an exercise (see Recording an exercise), an HR zone gauge, divided into five sections, is shown around the outer edge of the sport mode display (for all sport modes that support HR). The gauge indicates in which HR zone you are currently training by lighting up the corresponding section. The small arrow in the gauge indicates where you are within the zone range.
In addition, there is a dedicated display for HR zones in the sport mode default display. The zone display shows your current HR zone in the middle field, how long you have been in that zone, and how far away you are in beats per minute to the next zones up and down. The background color of the bar also indicates which HR zone you are training in.
In the exercise summary, you get a breakdown of how much time you spent in each zone.
