i Own the polar ft7 hrm, and i was wondering whether it okay to wear it for when im cleaning rigorously. I pause it every time in not doing anything, and i only keep the watch on for about 2 hours. for 2 hours, constant cleaning or walking around i burn 800 calories, wondering if this is accurate? im 5f0 and 176 lbs.

    I have the same HRM and this seems about right according to your height/weight. I have used it for cleaning/lawn mowing etc and I don't burn quite that much but I'm taller and weight less --- so plan on burning less as you lose weight :) Same thing with zumba... i burned more when I was heavier --- even though I work harder now.

    Sounds accurate. I personally only log actual exercising. For me logging stuff that really is just daily routine stuff feels like I am cheating myself. Look at it like this. If you don't log that stuff and go off actual exercise vs food intake it makes for a decent buffer. I don't like to pad the numbers at all. I always overestimate my calorie intake and underestimate my calorie burns. Just my humble opinion.

    Hard to say if that's accurate or not. How did you calculate your max heart rate? If you're just using a formula then unless you are lucky enough to have a heart rate that matches the formula (and I wouldn't count on that) then I would say the numbers should be taken with a grain of salt.

    But I've given up trying to argue that with people ;)

    Well theres no need to argue here haha. i only log it once a month when i have a massive clean out, hence the 2-3 hours of cleaning. I clean everyday but i dont log that as its not much of an effort.

    I have the FT7 and I find myself constantly questioning the accuracy of some of it's readings. Here's what's happening:

    I am a 48-year old female, 5'4, and currently weigh 247. The watch set my max heart rate to 172, although that is different from most of the formulas I've seen. It seems to start the Fitness Zone around 104, which seems a bit low to me. I wear this most often while working out on the elliptical trainer (Crossramp, no arm work). I enter my weight and age into this machine when I start a workout. The machine also has a heart rate monitor built in and I find that it picks up the signal from my HRM's transmitter so my heart rate is displaying the whole time on the machine and it's about the same as the watch shows, maybe a few seconds slower in changing. For a 60 minute workout, the machine shows me burning around 800 calories, but the watch only shows about 395. That's a huge discrepancy. During this time my average heart rate is in the 140s and my max heart rate always hits in the 150s (and sometimes stays there for quite awhile when I'm having a good day).

    I know this is asking you to estimate but does this 395 number seem low? I'm not taking it slow and easy on the machine, and while I've always known that MFP's numbers for the elliptical trainer are way too high, I really thought I was burning in the 600-700 range. Would adjusting the maximum heart rate that the HRM sets make any difference? It's not a huge thing because the HRM has definitely helped me to push my fitness levels higher. Just in the six weeks I've had it I've found that I have to work much harder to elevate my heart rate now. But I'd still like to feel like I can trust the number of calories I'm burning.

    The only way to know your true max HR is to push yourself to it...preferably with a doctor's supervision. As far as if that's accurate...I burn 550 - 600 on an hour long run and an elliptical is going to be less intense than that. I would say you're getting a somewhat decent reading there.
