Fitness test
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 and increase your physical exercise.

Heart rate also in water with H7 heart rate sensor (requires H7 sensor)
Pair up the A300 with Polar H7 Bluetooth Smart heart rate sensor to measure your every heartbeat during exercise, and find out if you’re mostly burning fat or improving your fitness. This is the most accurate way to measure calorie burn in heart rate based training.

Changeable wristband
The A300 has an easy-to-change wristband available in six juicy colors: charcoal black, powder white, sorbet pink, mellow yellow, storm grey and indigo blue.

Energy Pointer
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.

Smart Calories
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 your physical activity.
