    Thanks guys. I'm tossing that wrist HRM and getting a chest strap one today.

    In tears......

    You can definitely burn 1000+ cals in an hour. I have. I only have the watch kind (no chest strap). I set my watch with all my personal information (age, height, weight, etc) and it started giving me different numbers than what I was getting prior to setting it. Don't doubt yourself or your workout. Only you know how hard you go at it.

    Sorry, but probably completely wrong. Turbo Fire is a good workout, but that would be an insane burn.

    Have you entered your weight and stats correctly? Maybe its basing its calculations on an incorrect weight input. Might want to check it :)

    Chest ones are more accurate.

    I have a similar heart rate monitor, and while it runs a little bit on the high side, I check my heart rate every 5-10 minutes during workouts like boot camp or Zumba to be sure the heart rate it displays makes sense. If you know what is typical for you at rest and during exercise, start with comparing that to your monitor's results. Then use an online calculator to determine what the burn should actually be for a person of your body composition at that heart rate and length of time. (Try http://www.shapesense.com/fitness-exercise/calculators/heart-rate-based-calorie-burn-calculator.aspx). I check my heart rate every time I work out and use an average (about 500 calories for a good boot camp class, about 800 for high impact Zumba, about 600 calories for an average Zumba class, etc.). Then, once I know what I likely burn during a certain type of workout, I no longer wear the heart monitor - I use the average readings when I log my workouts.

    I am a 220(ish) pound male and I can burn over 800 cals in 30 minutes of semi-intense cardio and 30 minutes of heavy lifting.

    If I was to do 60 minutes of HIIT I would easily burn over 1000 cals.

    I have the Polar FT7 and I find that my calories burnt using the HRM are actually more than what MFP and the machines say!

    Maybe I am just lucky, you may be lucky too!

    Some people burn a lot more calories than others. I really fell bad for the people who were thinking they were burning 600+ cals only to find out it is closer to 250!

    ETA I should also mention that although I am overweight (bordering obese by BMI) I have a VO2Max of 50.

    I would just like to add that it IS possible to burn 1000 calories in an hour. When I run for 60 minutes, I burn close to 900 calories. My average heart rate is usually in the 170's. I do a lot of speed work and interval training.

    Calories burned calculates according to the following factors:

    Gender
    Age
    Height
    Weight
    Heart BPM / Average Heart Rate

    I used to have people tell me that MY burn was off because THEY did the SAME exercise and burned almost 1/2 the calories *I* burned.

    I'm just tossing this in - be sure to have your blood pressure checked. If you have high blood pressure and it's not controlled, that impacts your heart rate and calories burned - but it's not a SAFE way to burn calories! Best to get a quick check to be sure.

    I guess I'm tossing mine too. Yesterday it happened the same thing to me too Strech40/Core20 840 calories and today after doing Fire EZ 55 (for 55 minutes) I only burned 56 calories. I won't that to ruin my date I guess you are constantly training.

    Thanks for this post otherwise I would have still believed on my wrist HRM

    Help. I think my HRM is giving me false results. It said I burned 1098 calories from Turbo Fire Core (20 Min)+ Turbo Fire Strecth (40 mins)
    That seems to good to be true. I have the New Balance HRM that just goes on your wrist, no chest strip.

    Am I wrong, could this be right? (please say its right)

    Hi - I know these workouts, I've done TF and yeah this is way too many! For the others these are "recovery" workouts for toning/stretching. Your heart rate won't get much over 65% on these. I'd estimate just about 300 for Stretch 40 and 150 for Core 20

    In fact for these you could sub Stretch 40 for the MFP calculation for 40 mins of yoga, because that's basically what it is.
    And Core 20 you could log it as 20 mins of calisthenics

    There is a slight difference here, your HRM calculated average HR, but equation uses average % of maximum HRM, which is calculated from your avg. HR. The other variable that you are missing is HRM assume a certain V02Max (maximum oxygen uptake) this is really the key, and is only estimated in HRM's which make them better then other measures but not perfect as the V02Max is just estimated (unless you have an HRM that allows you to input your V02Max, after you have calculated it, hopefully correctly).
