Versa 2 calories burned accuracy concern

[JennRemai2019]

So I have a versa and up until two weeks ago it was counting calories correctly during my workouts, as I have favorite ones I like to do, I sometimes do them again weeks later. My watch is in the same position, but it is saying only half the amount of calories that I burned in the exact same workout I had done the week before. I am a fitness instructor, so I know its the same intensity level. Anyone have any suggestions?

Hi @JennRemai2019, welcome to the Community Forums.

Thanks for bringing this to our attention and for the details that were shared. Fitbit devices combine your basal metabolic rate (BMR)—the rate at which you burn calories at rest to maintain vital body functions (including breathing, blood circulation, and heartbeat)—and your activity data to estimate your calories burned. If your device tracks heart rate, your heart-rate data is also included, especially to estimate calories burned during exercise. The number you see on your Fitbit device is your total calories burned for the day.

Your BMR is based on the physical data you entered in to your Fitbit account (height, weight, sex, and age) and accounts for at least half the calories you burn in a day. Because your body burns calories even if you’re asleep or not moving, you see calories burned on your device when you wake up and will notice this number increase throughout the day.

Let me know if you have any additional questions.

So I realize all of that but its not counting the same during the
"exercise" portion when I specifically turn that on to the "workout" mode.
