Fitness Improvement
For those who want basic heart rate-based features to keep their fitness training simple.
Body measurement features
Automatic age-based target zone – bpm
To help you train safely and effectively, the training computer determines your heart rate target zone limits automatically according to your age-based maximum heart rate (220 minus age). The limits are determined either in beats per minute (bpm), as a percentage (%) of your maximum heart rate, or as a heart rate reserve (% HRR). See also Maximal oxygen uptake (VO2max) and Manual target zone.
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.
HR-based target zones with visual and audible alarm
You can define your target zones for a training session based on heart rate to help define the right intensity. When you are out of the preset zones, the training computer will give a visual and audible alarm.
Manual target zone – bpm
This feature enables you to define the target zone as you want and is suitable for your training. You can set the target zone for your training as beats per minute (bpm), as a percentage of your maximum heart rate, or as a percentage of your heart rate reserve (HRR%).
Polar OwnCal® – calorie expenditure
Polar OwnCal calculates the number of kilocalories expended during training. This feature allows you to follow the kilocalories expended during one training session and cumulative kilocalories expended during several training sessions. Some Polar products also estimate the fat-burning percentage (fat% on display), that is, kilocalories expended from fat during a workout which is expressed as a percentage of the total kilocalories burned.
Polar OwnCode® (5kHz) – coded transmission
Coded heart rate transmission automatically locks in a code to transmit your heart rate to the training computer. The training computer picks up your heart rate from your transmitter only. Coding prevents interference from other training computers.
Training features
Graphical target zone indicator
This feature points out graphically on the display the zone you are in during a training session helping you to stay on the desired intensity zone.
HeartTouch – button-free operation of wrist unit
When HeartTouch is on, different training information during training can be accessed without pressing buttons, for instance, when gloves make pressing buttons difficult, by bringing your training computer close to your transmitter.

The Polar F4 heart rate monitor is an entry level training aid. It is very simple in use and provides the user with the most essential workout data. Thanks to the textile chest strap with WearLink+ transmitter it very accurately measures the heart rate, which can be displayed in bpm or as percent of the maximum heart rate. The Heart Touch function allows changing the displayed data without even touching a button. It only needs to be brought near the transmitter. Coding the transmission prevents interference from other workout devices. The clear backlit display features graphical zone target indicator. The target zone is set automatically after entering necessary data and the user is informed by audible alarm when it is exceeded. The FT4 also measures the calorie expenditure and stores the workout summaries. Thanks to several watch features it can be used as a regular wrist watch.
