Do calories burnt change the fitter you become?

Yes the healthier you become, lower weight, better cardiovascular system the harder it is to get your heart rate up so you will need to work harder to burn the calories you burn at the begining.

I was wondering that too..seeing people doing TurboFire, just like me, but burning way less...must be b/c I have some lbs on them! Thanks!

I was going to comment on your workout today syaing you make my cal burn for the Fire 55 I did look like nothing!

When I was heavier I was burning more cals and now that I'm getting closer to my goal weight I have to push even harder!

So as I adjust my weight in mfp it will automatically adjust my calories burnt right?

I have noticed that it does this for me, but this is why I want to invest in a really good HRM with a chest strap or a bodybugg. The reason being, I increase the intensity of the same workout each time I do it so I don't do the same amount of work each time...that means that I should not see the decrease in calories burned. For example, when doing something like an Insanity workout, as I progress fitness-wise I push myself harder to lower myself further during push-ups or jump higher during the plyometric moves. I also like to run in place faster than before.

For now I use the MFP calculations, but I think that when we increase the intensity each time we workout the calories burned should not go down. It's only by doing the same workout the same way that the calorie count reduces, which is why we are told to have variety in our workouts "so our bodies don't get used to it" (I'm sure you have heard that before) and to always wokr at increasing the intensity every time.

Yes. As your weight goes down MFP adjusts down your calorie burn (I like the weight loss just hate losing the calories lol)

Well, according to physics, moving the same weight the same distance will require the same amount of energy. Unfortunately, physics isn't always right. Just like you can get better gas mileage out of your car by keeping it tuned up, you can get better Calorie Mileage out of your body by "tuning it up" with exercise. While that is great health wise in that it means your body is working more efficiently, it does mean less of a calorie burn from the same workout because your body may not have to recruit as many muscle fibers to do the job.

Nice way to put it! Yes!

I am not sure about the fitness level and calories burned when it comes to do fitness classes. I believe a lot has to do with what you put into it. And how many of your muscles you activate. I am also a group exercise instructor. My fitness level is significantly higher than many of my participants'. When I compare calorie burn, I typically burn quite a bit more. When I take a comparable class from another instructor, I burn a bit less. I think when we instruct, we do moves with more enthusiasm and precision. Bigger motions to help participant see, etc. I think that might account for some of the 400 cal. Age has something to do with it too. I think HRMs figure age/expected lean mass into the configurations. Men under 30 have more testosterone so should have more muscle (generalization, not specific to the individual, but that is what HRM formulas use, generalities...) Just some ideas.

I agree, but the physics IS right. However, as you said, you are basically giving yourself a stronger engine with which to do it. The energy required is still the same, but the engine doing the work is a little different. A 30 mile daily commute at 50mph burns the same amount of gas, but if you want to consume more fuel you simply speed up to 60

Yep, annoying isn't it? The smaller and fitter you are, the less the payoff! running a mile for Mr/Mrs Average is supposed to burn 100 calories, at my height and weight it burns about 79!

Gain about 40 lbs of fat and you too and burn 100+ calories in the same time.
