Just curious what everyone's opinion on here was about the great debate in cardio. Every "expert" has an opion. Does it all make a difference or in the end is it all about calories in and out? I have a feeling it all has to do with where you are starting at as far as body fat levels and fitness capabilities.
Someone with 30% body fat probably has no need to do HIIT cardio but as they get leaner they become more adaptive to the cardio so HIIT would be more effective as far as getting the heart rate where it needs to be. Or would we argue the the heart rate zones are useless as well?
