Polar Fitness Test measures your aerobic fitness at rest in just five minutes. The result evaluates your maximal oxygen uptake (VO2max). Fitness testing will motivate and inspire you to start, maintain or increase physical exercise.
EnergyPointer is an easy-to-use feature which tells you during exercising if the main effect of your training is fat burning or fitness improvement.
Heart Rate Zones
Select and monitor the intensity of your training easily with heart rate zones and follow heart rate based training programmes. The default heart rate zones are based on your maximum heart rate: very light (50–60% HRmax), light (60–70% HRmax), moderate (70–80% HRmax), hard (80–90% HRmax) and maximum (90–100% HRmax).
The most accurate calorie counter on the market calculates the number of calories burned. The calculation is based on your individual data: your weight, height, age, gender and the intensity of physical activity.
Get motivating feedback immediately after exercise by syncing your A300 with Polar Flow app or web service.
Activity Guide shows you different ways to reach your recommended daily activity goal and tells you how active you've been during the day.
Activity Benefit gives you feedback on a daily, weekly and monthly basis. The more you move, the greater the health benefits are. You can check up on how you're doing either from your smartphone or from the web.
Activity Tracking 24/7
24/7 activity tracking registers your daily activity at different intensity levels. A300 tracks your steps, calories and sleep time, and notifies you when you’ve been inactive for long periods of time.
Activity Zones track your daily activities on five intensity levels: resting, sitting, low, medium and high. You can see how much time you spend on each level in Polar Flow web service and app.
Sleep Duration and Quality
A300 tracks your sleeping time automatically from when you lie down and your body movements slow down. By showing you the amount of restful versus restless sleep, Polar Flow gives you a detailed look into how you sleep at night. You can see if your sleep’s affected by any changes in your daily life.
Inactivity Alerts with Vibration
A300 gently vibrates when you have been sitting for too long.
Steps and Distance
A300 counts your steps taken during the day and the distance based on the steps.
