Do you subtract calories from your burn?

hmm...never, ever thought of that! Looking forward to seeing what other people say! Hopefully someone can shed light on this question though. Let's just say your body burns 100 calories an hour at rest. So if I walk slowly for an hour and burn like 150 calories, did I really only technically burn 50 calories for that hour of activity?

In theory, that would be the correct thing to do. In reality, I don't worry about it. There is enough inaccuracy and estimation in the entire process that I don't worry about that. You can drive yourself nuts. For example, what about the fact that after the class your heart rate is still higher and you are still burning calories at a higher rate than normal?

If you did a very light workout over a long period of time, that might make a difference, but for an hour class, not worth it.

Just my opinion of course. I record the calories off the gym machine, and it's been working fine.

yes...I subtract my normal burn as they have already been accounted for...no need to count them twice...it is also safer if you are going to be eating all your exercise calories

I guess I should have added I used a chest strap/ HRM

me too

I don't, because over the course of the next few hours when my metabolism is elevated and I am burning more calories than I normally would by just existing, I never track those... so I figure by not subtracting my "existing" calories from my burn and not counting the extra calories from my after burn, it all evens out in the end...

This exactly.

I do this when I use the MFP estimates because for me they estimate high. Everyone is probably different. For example, when I do Body Pump with my HRM, I burn between 200-300 calories. I've seen calorie burns between 400-800 calories. They are probably lift heavier or moving quicker than I am.

To each his own.

I totally burn 400 cal in pump class (i lift heavy) and on release 80 i was closer to 500....]

I can understand why someone would deduct those calories... I just never bothered and it had no impact on my progress or maintenance.

I agree. I also log what ever MFP or the equipment at the gym gives me, and I just don't eat all of my exercise calories most of the time. No impact what so ever on my weight loss or maintenance. But we are all different and we should do what works for us, and not for somebody else.

I put exactly what my heart rate monitor says which is about half of MFP. And to all of you talking about EPOC Wahoo to EXCESS POST OXYGEN CONSUMPTION... IT rocks! Great time to do some errands will your body does it's thing!

If you want the most accurate count of Kcalories bruned you need to get a Heart rate monitor with a chest strap that you can personalise with your height weight and age. The Machines as the gym do not accuratly monitor your heart rate as every person is a different height, weight, age and have different Cardiovascular Endurance. I know I put my burn Kcals in but I don't make them up. MFP always tells me I'm under my Kcalorie intake!
