Replacement Blaze not recording active minutes

[Bcobbold]

My first blaze which was a xmas present suddenly stopped tracking active minutes. I was sent a replacment however that isnt working either. I was at the gym this evening doing a zumba class for an hour and then weights for about 45 minutes and it hasnt tracked a single active minute! I have done all the usual restarting etc but i have had this literally a week! Can any one help please?

Hi there @Bcobbold. Great to have you in the Fitbit Community Forums!

I'm sorry to hear that you're not seeing active minutes on your new Blaze replacement. Now, I'd like to explain how the active minutes work to make sure you earn them.

Fitbit devices calculate active minutes using metabolic equivalents (METs) and you earn active minutes for activities at or above about 3 METs. To stay in line with the Center for Disease Control's (CDC’s) “10 minutes at a time is fine” concept, minutes are only awarded after 10 minutes of continuous moderate-to-intense activity.

This means that whenever you're doing an activity, you need to make sure to keep the same intensity for at least 10 minutes in order to earn active minutes. If you lower the intensity during the activity before 10 minutes, most likely, they will not be awarded.

The more calories you burn the higher your MET value, so therefore the more calories you burn the higher your total active minutes. Assuming you're active for at least 10 minutes at a time, green spikes on your calorie graph typically indicate that you’re earning active minutes.

Hope you find this information useful and anything else you may need, I'm here to help! 🙂
