Wheres the logic?

I finally got a heart rate monitor (polar f6).

Anyways, after a workout being in my target range it says that 45% fat was burned (I assume fat calories)

Yesterday, I did a maize maze for an hour (best time yet) and I couldn't push myself hard enough to get in the target range (bf was slowing me down) Anyways, I recorded everything anyways. After the maze it said I lost 60% fat.

Why is this so? Should I be incorporating low impact days into my exercising schedule. I'm so confused :huh:

I'm going to leave this one for those of us with Polar HRM, and there are several of us. Mine is a cheapie MIO, which is all I could afford.

What I can tell you is that different zones burn different percentages of calories.

A higher target heart rate burns fewer fat cals than a lower one BUT,
if you work out LONGER in a higher target heart rate, even though the percentage of fat cals you burn is lower, you burn MORE OF THEM, so you're actually burning more over all.

At 60-65% target HR, you burn 4.86 cals per minute.
At 80-85% target HR, you burn 6.86 cals per minute.

This exerpt (http://www.sparkpeople.com/resource/reference_intensity.asp) should help you understand a little better.

""The most important thing to remember is that exercising at a higher intensity is better than exercising at a lower intensity when it comes to burning calories. There is a lower-intensity “fat burning zone” in which you utilize a greater percentage of calories from fat than at higher intensities. However, the total number of calories burned at that rate is less. For example, let’s say you bike at a low intensity and burn 100 calories. Seventy-five of those calories burned might come from fat. At first glance, that looks good. But if you bike at a higher intensity for the same period of time, you might burn 200 total calories, with 125 of those coming from fat. Your percentage of fat calories burned drops, but you burn more total calories and more total fat calories at the higher intensity.

The bottom line: for sustained weight loss, you have to burn more calories than you take in. Trying to focus on burning fat calories won’t help. Calories are calories –the goal is to burn as many as possible. ""


You are correct to mix up the intensity of your workouts. You trick your body and confuse it some, and
that creates 'metabolic turbulence' and keeps your body on red alert to what you may demand of it next workout.

Best of luck to you and btw :flowerforyou: welcome!! :flowerforyou:

Thank you ... that was very helpful! :happy:

This is kind of off topic, but I've seen people say that their heart rate monitors give this percentage of fat burned. I have a Polar F11 but have never seen any kind of percentage on it...where do you see this percentage? Do you think my HRM has this feature?

I have the polar F6 and I have to go into the are where it says File and find the day I exercised and it tells me how many calories, my max heart rate, my average heart rate, and the percent fat burned. I just found all of this information a couple of weeks ago (and I've had my HRM for 6 months) by just using the up/down arrows to see what everything did.

Ohmigosh Lyla...thanks! lol...I haven't played with mine too much, but I know it has a lot of bells and whistles I've never used...I really should have gotten the F4 or F6...the F11 is really too fancy for me lol

I am thankful you posted this thread.

Russia, that is some darn good info. Makes total sense.

Since getting my F6 ( oooh baby, I lub ya ) I found I am working in the higher heart rate zone, and had this same question. I burn more cals with 90% but less of them is fat %. I do mix up my exercise a LOT because I get bored to easily.

Thanks again:flowerforyou: :flowerforyou:
