Alright, this has had me wondering for a while now.

Say I burn 2400 calories per day. Average of about 100 calories per hour. BMR rate. Without exercise, lifestyle, etc, etc factored in.

I know go on the treadmill, slow walk, for 30 min, and burn another 100 calories. Would that be on TOP of the 50 calories I ALREADY burn that half hour, or are those 50 calories included in the 100 that I burn during the 30 min on a treadmill.

Am I burning 200 calories that hour, or am I burning 150 calories that hour I guess is what I'm asking.

I don't think you can look at it as adding the amount burned while doing cardio to what your body would have burned in a completely relaxed state. You are simply burning more calories while doing cardio that while sitting still. You are going to burn a different number of calories every day, every hour depending on so many factors. I wish I could construct a sentence with the point I have in my head... but alas I'm an idiot:D

I was just throwing figures out there to explain what I meant.

Even if I only burn 30 calories that hour, if I walk on the treadmill, and burn 100 calories, I'm really only burning 70 calories through exercise. The rest is being burnt by my BMR.

What you want to do is get a heart rate monitor, and run a baseline for that time of day on a rest day. Then on the day when you do the exercise, you can compare Calories burned and see how much difference the exercise made.

The answer is yes - the total calories you burn while exercising includes your basal caloric burn rate. As Zen said, you simply determine it on a rest day and subtract it out.

You are beginning to split hairs though - just make sure you are really pushing your heart rate up while doing your cardio, and take the total burned as exercise. If you want to factor it into a TDEE, just subtract 1 hr (or whatever total time you exercised) of your BMR and then add in the exercise calories estimated by your HRM.

I'm kinda tight on money right now. Just bought a squat rack and some more weights, so the HRM is going to have to wait.

But I think I got my answer. Thanks guys!
