I got this for Christmas, and used it for the first time today.... I took a walk for 40 min at a brisk pace...my average heart rate was 119...it says I burned 225 calories. That seems really high...the database here says 133 cals for a 40 min brisk pace walk..

Anyone know what is going on? I was really hoping this thing would be accurate! I am 5 4 and weigh 118-119...

    How long was your heart rate "in zone". Do you see where it lists that in your training records? 225 calories burned is definitely possible if you spent most of that time with your heart rate elevated "in zone".

    Sounds right to me. I use a different brand but high impact Zumba is about 400-450 for 60 minutes for me at 5'9" and 135. So I think the walking pace/time/burn seems reasonable.

    I would assume its all math. Everyone is different regardless. Some people may have a higher or lower heartrate and from that number, it would calculate how many calories you are burning. There are alot of variables that can go into calculating calories. Sorry math geek here...

    By the way, I have been also thinking getting a heartrate monitor myself. Do you like what you got?

    Sounds right to me! You can double check you put in your correct weight and height into the HRM but other than that you're good. 119 sounds right for walking quickly. ~200 cals for 40 min sounds reasonable.

    Yep that sounds about right to me. I have the same model and 119 is a moderate heart rate. If I run I'm usually 170-180 which = mega burn! It's so much fun working out with my Polar FT4 :-)

    When I put your age, weight, ave. heart rate and the time you worked out into the calories burned equation, then i got 272. So that doesn't seem to high to me

    After I got mine I noticed MFP and the treadmill both were underestimating my burn. Yours seems about right.

    Sounds correct to me for sure. I would trust your HRM.

    119 calories sounds very low to me for 40 minutes brisk walking.

    I have a polar FT4 I bought last spring 2011 and when weight /age/ height are all entered correctly it is very accurate, I used that compared to same entries into my precor elliptical machine user program and got nearly the same reading only off by 10 calories on the burn, for me 35 mins was 270 calories but this is on an elliptical and I am much heavier.
