Versa is tracking my calories way too low

[L4ur3nF]

Hi. I’m now on my second fitbit versa,

I do 2 personal training sessions a week and and have tried a few different settings for tracking my workout. 
Iv tried workout, Circuit training and interval training but I feel that the calories burnt is extremely in accurate. My workouts are just over an hour long but on average it says I only ever burn 80 calories per workout. 
Am I setting the workout  wrong or does anyone else have this problem?

Hi there, @L4ur3nF. Welcome to the Community Forums. I understand where your concern is coming from. 

Have you checked if your settings are set correctly? 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.

Note that in certain regions, you see kilojoules instead of calories. To change your units of measurement, see How do I change the units of measurement in my Fitbit account?
