      Heart rate zones

      Heart rate zones provide an easy way to select and monitor the intensity of your training and to follow heart rate based training programs. The default heart rate zones are divided into five zones based on the percentage of 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).

    • HRmax (age-based)

      HRmax (age-based)

      The highest number of heart beats per minute (bpm) during maximum physical exertion. For a rough estimate of your maximum heart rate, subtract your age from 220. HRmax is a useful tool for determining the intensity of training as intensity zones can be defined using HRmax. Some Polar products define maximum heart rate during the Polar Fitness Test, see also HRmax (Polar Fitness Test -based).

    • Polar OwnCal® – Smart Calories

      Polar OwnCal® – Smart Calories

      The most accurate calorie counter on the market calculates the number of calories burned. Calculation is based on your individual data: your weight, height, age, gender and the intensity of physical activity. Smart Calories are available in heart rate monitors and activity trackers.

    • Heart rate – bpm / %

      Heart rate – bpm / %

      Heart rate is the measurement of the work your heart does. Heart rate can be expressed as the number of beats per minute or as percentage of your maximum heart rate. Heart rate can also be expressed as a percentage of your heart rate reserve, meaning the difference between your resting heart rate and maximum heart rate (HRR = HRmax - HRrest). In Polar software or during strength training, heart rate can be displayed as a graphical trend.

    • Training Benefit

      Training Benefit

      Motivating feedback that’s delivered straight to you immediately after exercise is something that can help all of us.
