Training with Polar Loop

The Polar Loop offers several options for tracking your training sessions, allowing you to choose what best suits your activity and preferences. You can track sessions manually—either with the Flow app or with the device (using the Flow app to start and stop the session)—or use automatic tracking directly on the device.

Manual training recording

You can manually start and stop your training session using the Flow app. Before starting the training session, you can choose whether to record it with the Flow app or with your device.

• Recording training sessions with the Flow app:

  When you use the Flow app to record your training, both heart rate and location-related data are recorded, and you can monitor them in real time during your session. You can also receive voice guidance and use quick targets.

  Best for: Planned workouts like gym sessions or runs, where precise start and stop tracking is important, or when you need GPS data (speed, distance, route) tracked.

  Keep your phone nearby during the session to ensure GPS accuracy and uninterrupted heart rate tracking.

• Recording training sessions with your device:

  When recording with the device, you need to start and stop the session manually using the Flow app, but you don't need to carry your phone with you during the workout. Once started, the recording is handled by the device. When using the device alone, only heart rate data is recorded.

  Best for: Activities where you find carrying your phone inconvenient, or when the start of your training is too low in intensity for automatic training detection to recognize.

Before you can manually record training sessions with the Flow app or your device, the device must be paired as a heart rate sensor on the Training settings page in the Flow app.

Automatic training detection

Automatic Training Detection enables your Polar Loop to detect and record workouts automatically—no need to manually start or stop a session.

When enabled, your device begins recording once it detects elevated heart rate and activity levels. The data is then automatically synced to the Flow app when your phone is within Bluetooth range. This feature ensures your training is tracked even if you forget to start it manually—and you don’t need to carry your phone during the session. You can focus fully on your training while your device handles the tracking in the background.

Best for: Spontaneous or casual activities such as brisk walking and cycling.
