Need Help With Calories!

[Wilderbeast]

Hi guys!

Got my Fitbit charge 3 yesterday after finally starting the healthy eating and exercise lifestyle two or so weeks ago. Made a lot of progress so far and I am a happy chap! Question though, how does the Fitbit count calories burnt? Apparently during my 30 minute stationary bike workout yesterday (using the spinning exercise option on the charge 3) I managed to burn 504 calories. This seems quite high but I am a 22.4 stone man, 6ft 3 tall and I am 28 years of age. Does this sound right to you guys? also, just being alive with average movement my Fitbit tells me I am burning around 2600-2900 calories per day with BMR. I have done several tests on my heart rate (fingers on the wrist) and it is crazy accurate with what my Fitbit is picking up, maybe 1 or 2 beats per minute under or over but mostly it is accurate.

Thanks guys!

Spinning is high intensity. Are you doing that on your bike?

I just use Bike and log it that way as mine is not high intensity

I would say its a mix of moderate/high. I keep up the pace and do small 30-50 second intervals (working my way up to a minute) every 5 minutes or so. The short bursts are pretty intense leaving me blowing out my arse. Sweating buckets from the 5 minute mark with pumped quads after the 30 minutes :D. I do this once in the morning then in the evening, I am addicted lol.
