Sense 2 is not tracking my workouts accurately

[SHarvey84]

Anyone else noticed that your sense 2 not tracking workouts correctly? For example I've just tracked a weightlifting session, that never really raises the heart rate by much and apparently I've burned over 1000 calories, which never never happens in weights. Checked all my settings and all fine as it was working fine yesterday but only change today was it was plugged in to charge

It appears that the functionality of the sense 2 is falling with increasing things not working, anyone else noticed this??

Hi there, @SHarvey84. It's nice to see you around the Fitbit Community Forums. Thanks for bringing this to my attention. I understand your concern, I will do my best to help you with this!

This type of issue is likely caused by the optical heart rate sensor struggling with rapid heart rate changes and significant wrist flexion common in lifting.

Sometimes the sensor can confuse movement noise with heart rate, causing inflated, high-calorie readings. The Sense 2 requires a very snug fit, higher on the wrist (above the wrist bone), to improve accuracy during activity.

With that being said, I'd recommend moving your device higher up your arm for training and also restarting your Sense 2. 

After checking the above, give it another try and let me know if the issue persists.
