How do you do a good heart rate reading on your Fitbit?

Don't see a heart rate or does the heart rate have a gray color on your Fitbit? That might be because of energetic movements you've made during an intense workout. In that case, the signal is too weak to perform a good measurement. Relax your wrist and stand still for up to 10 seconds. The heart rate reading should start up again automatically on the screen of your Fitbit.

Heart rate monitoring is enabled on your Fitbit by default. Is it disabled? That means your watch can't monitor your heart rate. You can easily enable this feature.

1. Open the Settings app on your Fitbit.
2. Tap Heart rate and choose Om. Your Fitbit can now monitor your heart rate.

The sensors of your Fitbit need to make proper contact with the top of your wrist. The Fitbit can't be too tight or too loose. Otherwise, the sensors don't make proper contact with your wrist. There needs to be enough space between the watch strap and your wrist, so your skin can breath. When you wear the watch the right way, your Fitbit can measure your heart rate most accurately.

If nothing helps, reset your Fitbit. You can either perform a hard reset or a soft reset. Note: with a hard reset, you reset the watch to factory settings. In this article, you can read how to reset your Fitbit model.
