Do exercise calories subtract BMR?

[0rganiker]

I've been biking to school and tracking it using my Surge. Today, for example, it said I burned 274 calories during my biking exercise.

What I'm wondering is if they're including my BMR calories in that measurement. Even without biking I would have burned 30 or so calories, so does exercise tracking include that? I would rather that it not include that, because it feels as though the number is then inflated. Not all of those calories were due to actually biking.

I know I could figure this out easily enough by just starting a "bike exercise" and then not actually biking, but I'd rather not mess up my stats if someone else already has an answer.

Thanks.

Fitbit always includes the BMR calories when showing calories burned. So, in your example the 274 calories were partly BMR and partly activity calories.
