This is my first time using it. I was shopping at Costco, twice really because I'd forgotten something and had to go back in.

Duration: 1:37:03

Calories: 608?? Seriously??

I used my Ft4 for the first time this morning for my daily walk, 3.5 miles in 1:05 hours with hills got me 513 calories, so its possible! I assume all your info is entered correctly?

Yep. Wow. I had always heard MFP was overly generous with their burn estimates, but I guess not for me.

It gave me 600 calories for 2 hours of hiking. It all depend of your weight but that being said It is not very accurate outside of steady cardio.

I was expecting the same, but some of my friends here said it is way high on some things and way low on others, so annoying!

I could be right, but it also could be wrong. HRMs are made for aerobic exercise. They don't do as well with low intensity or all day stuff. And when I say low intensity, I don't mean speed walking, but I do mean Costco shopping. Lots of people (including me) tried to wear a HRM all day and got a ridiculously high number back (I then got a bodybugg, which is made for all day wear, so I can say the HRM reading was completely incorrect).

That said, it depends on your size and intensity... But I wouldn't eat back those calories if I were you.

I don't think I could eat them all anyway. I might do half. It was much higher intensity than usual for shopping, and I was constantly in motion including periodic bending and some heavy lifting. I'm around 80# over the top of the "healthy" range for my height. I was easily as sweaty as I get on the elliptical, and very rosy-cheeked as well.
