For recreational athletes who require all essential heart rate and timing features.

- Helps you train at the right intensity with personal sport zones
- The Polar Fitness test measures your aerobic fitness at rest and tells you your progress
- Displays calories burned

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.
- Average and maximum heart rate of each lap
- Average and maximum heart rate of training
- 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.
- 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).
- HRmax (Polar Fitness test-based)
Some Polar products predict your HRmax simultaneously with the Polar Fitness Test. This predicted HRmax value is more accurate than the age-based formula (220 minus age).
- 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 Fitness Test
Polar Fitness Test measures your aerobic fitness at rest in just five minutes. The result, Polar OwnIndex, evaluates your maximal oxygen uptake (VO2max). With the Polar Fitness Test you can measure your aerobic fitness by yourself, automatically and without any exertion. All you need is your training computer. The Polar Fitness Test is as accurate in predicting the VO2max as any sub maximal fitness test. The test is based on heart rate and heart rate variability at rest and personal information.
- 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.
- Polar OwnZone® – personal heart rate zone
Polar OwnZone® determines your personal heart rate limits for a training session. Depending on the day and time, your physical state may vary, for instance, if you are stressed or tired, or if you are not fully recovered from your latest training session, Polar can determine that information from your heart rate and guide you to your ideal training zone for that moment.
- Polar sport zones
Polar sport zones provide an easy way to select and monitor the intensity of your training and to follow sport zones based training programs. Training is divided into five zones based on percentages 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).

G1 GPS sensor features
- Distance – training, lap, and total
Distance (km, mi) can be set and measured in several ways. Training distance tells you the distance traveled during a training session. Trip distance tells you the distance from the latest trip reset. Lap distance tells you the distance of one lap. Total distance is the distance accumulated since the last reset. Odometer tells you the cumulative distance which you cannot reset.
- Speed-based target zones with visual and audible alarm
You can define your target zones for a training session based on speed. When you are out of the preset zones, the training computer will give a visual and audible alarm.
- Speed/Pace – current, average and maximum
Speed (km/h or mi/h) is measured with GPS, footpod, stride sensor or cycling speed sensor. Pace (expressed as min/km or min/mile) stands for the rate of speed. Pace is usually used in running. By setting a target pace, you can follow how fast you need to run in order to reach a certain distance in a predefined time.

Recording features
- Totals
Totals includes your training data starting from the last reset enabling you to follow your long-term training.
- Training files (with summaries) – 16
- Weekly history
Weekly history gathers your weekly training data. By selecting a week, you can review your training data for the week.

S1 footpod features
- Distance – training, lap, and total
Distance (km, mi) can be set and measured in several ways. Training distance tells you the distance traveled during a training session. Trip distance tells you the distance from the latest trip reset. Lap distance tells you the distance of one lap. Total distance is the distance accumulated since the last reset. Odometer tells you the cumulative distance which you cannot reset.
- Speed/Pace – current, average and maximum
Speed (km/h or mi/h) is measured with GPS, footpod, stride sensor or cycling speed sensor. Pace (expressed as min/km or min/mile) stands for the rate of speed. Pace is usually used in running. By setting a target pace, you can follow how fast you need to run in order to reach a certain distance in a predefined time.
- Speed/Pace-based target zones with visual and audible alarm
You can define your target zones for a training session based on speed. When you are out of the preset zones, the training computer will give a visual and audible alarm.

Training features
