I have read a few times (forget where) that low intensity cardio is very easily adapted to by our bodies and essentially what happens is that, after a few weeks the body compensates for the calories burned during cardio by lowering the bodies basal metabolic rate. Can anyone who is more knowledgable on the subject chime in on this?
Edit: ‘ready’ changed to ‘read’

I’m not sure about this. That being said, Layne is an advocate of cardio - particularly HIIT sessions done 2x weekly.
I, personally, (put this in the “things I can’t prove, but believe” category,) feel as though there are different ways and variations to do LISS cardio that are as or more effective than normal LISS types. I think the whole ‘have to stay at 120bpm for SS’ is hogwash. [/quote]
Yes, in the same video he mentioned that he is an advocate of high intensity intervals.[/quote]
It’s the concept of how the body becomes more efficient at repeated tasks. As such, the more aerobic work you do, the less of a caloric cost it puts on your body. That’s why you see so many folks who rely on traditional steady state work having to keep adding more and more to basically get the same effect on their caloric balance each day. Berardi, Norton, Poliquin, and many others have touched on this in their writings. You can get a nice explanation in a CSCS text if you care for the science involved.
A real life example of this that I’ve witnessed first hand (on a few occasions actually) is the ol’ “fat aerobics instructor”. I’m sure we’ve all see the woman who teaches 3-4 classes each day, does her own training, and yet looks nothing like the lean, toned specimen that you might expect. Or even the competitor who is doing hours and hours of steady state each day as their show draws near, adding more each successive week and yet they never really seem to be getting very far ahead.

Doesnt this just merit validity to varying your cardio methods? Example would be often switching your steady state from incline walking, to elipical, to stair master etc? [/quote]
Yes…and vary the pattern of resistance, elevation, & pace during the [treadmill, elliptical, stairmaster] session. [/quote]
This to a degree, but moreso, a matter of exertion levels. That’s the real key in terms of the benefits of interval based cardio approaches.
