I know I'm going to ruffle some more feathers out there by posting this, but hey, I'm here to help you get real information that will help you make choices and take actions that will get results!
I'm not here to just tell you what you want to hear. No, I want you to hear the truth, with evidence, and be able to make an informed choice from there.
I realize that will not necessarily make me the most exciting or popular person out there. But for those brave enough and serious enough about making changes in their bodies, by getting out of pain or transforming their body -- those people will appreciate this post.
I recently received this question that made me realize how many people out there are still using the heart rate info on machines as guides on how to transform their bodies. So let me give the truth.
In reference to the heart rate ranges posted on exercise equipment. They identify what your targeted heart rate should be if you want to burn fat, etc. based on your age. In my case, my heart rate while exercising is ALWAYS higher than that "fat burn" range. I would have to significantly slow down my pace in order to fall within that range. If my heart rate is not within that range, am I not burning calories efficiently? Is there a lot of merit to those targeted heart rate ranges? If I am not sweating, I don't feel like I am working hard. -- Nikkie
Target Heart is highly flawed. I have personal experience with contacting the user of some of these formulas and they had no real idea why they used them accept to say, "They were the popular tools used at the time". Guess it really doesn't answer why once they see the flaw they continue to use antiquated information.
To the point.
The Fat burning zone is supposed be the heart rate range where you will supposedly burn the most fat calories. Truth is, it cannot predict this. At best it can only partially suggest a percentage of use of fat, carbohydrates and protein.
Low Intensity - 60-65% MHR High Intensity - 80-85% MHR Total Calories expended per min. 4.86 6.86
Fat Calories expended per min. 2.43 2.7
Total Calories expended in 30 min. 46 206
Total Fat calories expended in 30 min. 73 82
Percentage of fat calories burned 50% 39.85%
