Smart Calories

The most accurate calorie counter on the market calculates the number of calories burned. The energy expenditure calculation is based on:

• Body weight, height, age, gender
• Individual maximum heart rate (HR_max)
• Heart rate during training
• Activity measurement outside of training sessions and when you train without heart rate
• Individual maximal oxygen uptake (VO2_max)
  VO2_max tells about your aerobic fitness. You can find out your estimated VO2_max with the Polar Fitness Test.
