Training with Polar Loop

You can record training sessions with your Polar Loop either manually or automatically.

Manual training recording

Manual training recording lets you track your sessions using your device as a heart rate sensor in the Flow app.

If your phone is with you during training, you can use its GPS to track outdoor activities, and use voice guidance and quick targets to guide your session. If you prefer to track only your heart rate, you can leave your phone behind. Your training data syncs automatically with the Flow app after you stop the session in the app.

Best for: Planned workouts such as gym sessions or runs where precise start and stop tracking is important, or when GPS data (speed, distance, route) is needed. Also suitable when the start of your session is too low in intensity for automatic training detection to recognize.

For more information, see Manual training recording.

Automatic training detection

Automatic Training Detection enables your Polar Loop to detect and record workouts automatically. You do not need to manually start or stop a session.

When enabled, the device begins recording when it detects elevated heart rate and increased activity levels. The data syncs automatically with 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. You do not need to carry your phone during the session.

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