I still hear the one about you have to exercise long and intense. When I said on one team that I couldn't walk as fast as a lot of people do, I was told that I wasn't doing anything to get exercise then. I also have friends who say you have to exercise at least an hour at a time (no breaks) for it to be effective. Doesn't matter that they have said short periods and can add them up work. Report
There really is no such think as a "FAT BURNING ZONE". Unbeknownist to most people, fat as a percentage of calories burned are highest while at rest. We are burning around 50/50, fat/sugars regularly. As we move and intensity increases we gradually shift away from the fat to utilize the more readily available energy source - glycogen. When you go all out, we are relying on mostly glycogen, AT THAT MOMENT. But these energy pathways are EXTREMELY complicated and after the exercise stops there is a process by which the body will pull from ALL resources to replenish this much needed quick surplus. That's why we do all that heavy breathing. Much oxygen is needed to replenish and convert fat to usable energy. Even though little fat is used during the High Intensity, all energy pathways get involved as the body prepares to "go again". So, by maximizing energy burning DURING the activity, the more the body will then convert the storage to a ready resource, after. Report
Yea I'm in the "confused about #5" camp. Report
@BEVT @NRADUNSKY I think the "myth" part would be that you can get rid of the thick layer of fat over your abs by spot training them. No one will argue that toning makes a difference in your appearance, but until you get rid of the layer of fat through cardio you're never going to have a "six-pack." Same is true for any other body part. Spot training *will* give you beautiful, well defined muscles; you just won't be able to see them until you burn off the padding. Report
BEVT, I agree. People always talk like training one area is a waste of time because you can't have spot reduction, like the only reason to strength train is some abstract metabolic or bone strengthening health benefit. However, you for sure SEE a difference when you spot train (at least if your weight isn't quite high), and that is what most people care about when they spot train. I have a flat stomach for a few days after doing ab workouts-- not defined by any means, but everything has some structure rather than falling out over the front of my jeans. If I am lazy about ab exercises the next week it comes right back. Report
I think people confuse the spot reduction and fat burning because if you really don't have weight to lose but are flabby and poochy in certain areas just working on those areas makes a big difference. I know that if I don't work my abs they pooch more. If I slack of my triceps and biseps I see a difference. Maybe it's confusing flab with fat. But I notice when I lay off my weights I do get an overall look of "fat" in those areas I use weights for. And no one ever explains that. It looks like fat, do some toning regularly and it goes away. So there's something to it. Report
Your advertisements cover the article you are presenting. This means, of course, I cannot read the article. I'm trying not to use a lot of cuss words in saying this. Does no one check to see how the articles are presented? Please, have someone with 1. brains 2. responsibility and 3.common sense, read this. Report
Pilates had given me back my waistline. OK, I am at goal weight but I am 63 and amazed at the toning effect. Report
Interesting that the #1 myth is spot reduction, yet I continue to see just those type of headlines here, makes me wonder Report
Great article. I've heard that if you run, after 20 minutes you start to burn up muscle and not fat. True? I didn't think it was a true statement, but wondered. Report
I've never understood the "fat burning zone". From my understanding the way to lose weight is to cosume less calories then your body needs in a day and so our bodies will resort to using the calories stored in the form of fat. The higher intensitiy of the workout, the more calories our body is burning. How does a lower intensity workout burn a higher percentage of fat? Just wondering. Report
I'm a exercise specialist and I tell my clients about the fat burning zone in this way:
We burn a higher percentage of fat when exercising at lower intensities but the total fat burned is often less. Think of it as money. Would you rather have 75% of 100 dollars or 50% of 300 dollars? Translate that to fat and you burn 75% of your calories from fat or 75 calories vs. 50% of your calories or 150! Burning at a higher percentage will net you a lot less fat in the long run, assuming you exercise for the same amount of time. I will take 50% of 300 any day! Report
For all of you confused about #5, please google 'fat burning zone myth'. It's not explained very well in the article so I can understand why you are still confused.

Someone made the statement that 'if you are not burning fat then you are burning muscle, and nobody wants that'. That is an incorrect assumption. You are still getting a proportion of your calories (energy) from fat when you are not in the fat burning zone, other energy sources include carbs and stored glycogen. If you are burning more calories overall, you will burn more fat (even though the PROPORTION of calories from fat is lower). Burning more calories, no matter where they come from, will lead to better weight loss (as long as you don't eat them all back).

Here is a good explanation that should clear up some of the confusion:

I've believed all these myths at some point, but I know better now Report
Please explain Myth 5 in more detail - I am confused whether I should be increasing the intesity of my workouts. Report
