Polar FT7 - Subtract Rest Calories?

stephabef

Do you guys subtract the cals you would have burned just by sitting from your exercise calories? For instance, my HRM told me I burned 122 calories in 20 minutes - do I subtract what I would have burned just by living for 20 minutes?

Ooo I would be really interested to know this too. If i was exercising for an hour, do i subtract 1/24th of my BMR from my total burn?
|sorry i didn't answer just wondered the same thing

yeah I always rest the calories burned when sitting down or resting. I reset the calorie count every time I'm starting to exercise again
so lets say I skate for 20minutes, i stop and rest take count of what I burned then reset and repeat

I do, but I have no idea if this is the right thing to do or not. I figure that my deficit is low anyway (to lose .5 per week, since I'm so close to maintenance), and I never have HUGE burns, that's negligible. I'm interested in other responses!

Ok, so I subtracted 19 calories... I took my BMR, divided it by 24 and again by 3 for what I'd burn in 20 minutes resting. I think this is correct?

Correct until the last part.. It's BMR divided by 24, and then by 60 to see what you burn a minute.. take that number times 20, to get what you'd burn in 20 minutes.

For the record, I've had an FT7 since april.. and never subtracted resting calories. I'll also lost 29 pounds doing it that way.. so in my eyes, it's not that important!

I did the same thing you did, though, just used a different formula. Divided BMR by 24 to get per hour, then by 3 (60 minutes in an hour/3 is 20 minutes).

Tracking calories burned is an inexact science to begin with (even a HRM is using an estimation), and trying to subtract the calories I MIGHT have burned from the calories I DID burn...everytime I workout...wow, my brain is hurting already.

If you're a math geek and it gives you a thrill, go for it. Otherwise, I think it's way more effort than it's worth.

I suppose I'd rather underestimate rather than eat back more than I should. And, yes, I do love doing math equations
