i know HRMs work best when you're keeping a steady heart rate whilst exercising, so i waited until i had a pretty decent task to do. i work at a bookstore. my task was to swap two sections (4 book cases each, 8 total) and so far ive only done half of it. which is an hours worth of work. swapping bookcases by taking chunks of books at a time, in each hand, walking them to the bookcase nearby and placing them there. sometimes squatting to grab books from the lower shelf and standing to put them on the higher shelf. no interruptions from customers, just straight shifting. i was sweating a little too. my HRM reads 377 cal burned in 1 hour. do you think this is accurate? i usually dont wear my HRM to work, but i wanted to test it out.

sorry if this seems silly. (coincidentally enough, i was swapping the humor and the sports sections. bahaha the irony.)

help!

    Your average work day should be counted into your energy expenditure (lightly active, very active, so on) on your MFP profile. You shouldn't track basic work tasks or life tasks as exercise unless they bring your heart rate up considerably. You burn calories naturally doing everything from breathing to sleeping - it only counts towards exercise if you're truly extending your body beyond its usual limits. Definitely don't track it. Only track swift walks, jogging, full blown steady state cardio, so on.

    Try finding your average heart rate and plug the numbers in to this site. http://www.shapesense.com/fitness-exercise/calculators/heart-rate-based-calorie-burn-calculator.aspx

    I managed bookstores for 12 years. Hell yah, that's about accurate. I think people who've never worked in a bookstore or reorganized shelves of books for a living have no idea how hard of work it is!
    (My 1st bookstore, the stock room was on the second floor, and we had to raise book shipments up to the top by loading them in a dumbwaiter with a pulley, then unloading them, checking them in, and then carrying them down the stairs to the sales floor. Random House shipments kept me fit!

    As to the people telling you not to count it as exercise because it's a part of your daily activity also have no idea how hard you're working during the day. I would come home from work WAY too exhausted to "go to the gym", or even to take a walk around the block. I was 130 pounds, and every inch was muscle. You can't tell me that's not exercise.

    :| I work as a manager of a very busy cafe and I am constantly on the move. I don't count it into my exercise calories. It isn't exercise - it should be counted into your daily expenditure. If it's that physically trying for you, consider it very active (i.e. spending a good part of the day doing heavy physical activity). I'm not discounting that she is working hard - I am saying that it is not exercise. Because it isn't. Unless her heart rate was significantly elevated on a STEADY basis, it isn't exercise.

    I mean this as supportive, but it is not exercise. The heart monitor is not to be used to record anything other than steady state and the heart monitor can even pick up when you get anxiety or scared and tell you have burned calories..

    This is not accurate what she says.. sorry..

    I know you are bad tired, but does not count for the reasons you say.

    i think it all depends on what her regular day is like - for example: if she works at the bookstore but normally is at the register and today she got this task - then yes she can consider that as additional exercise because its not something she does regularly.

    If swapping items from shelf to shelf is something that she does on the regular - then maybe she shouldn't consider it as exercise unless she is putting in extra energy into it (i.e lifting heavier books, going up and down stairs).

    Krissy - your normal schedule is to manage 1 busy cafe and its perfectly fine that you don't consider that as exercise. but if one day you have to run your cafe AND the one next door and you are actually sweating as you try to keep up with the demands of both... that's additional to your regular routine - therefore additional exercise.

    Just my thoughts.

    ... my HRM reads 377 cal burned in 1 hour. do you think this is accurate?

    I would say it's very unlikely to be accurate.

    You'll have burned c75-100 cals in that hour anyway as BMR.

    So a couple of aspects to consider, first being what contributes to work done and how much energy you expend. That's a function of mass and distance. Essentially you've moved say 300-400lbs of mass a distance of a few metres.

    To put it in perspective, move them a mile and you'll burn a couple of hundred calories.

    Now the issue of whether your HRM is likely to give you a meaningful estimate in those circumstances. HRMs are designed around research done on steady state, aerobic range, effort. You're unlikely to be in the aerobic range, your HR should be quit low so not getting into the range where the relationship between HR and calories is predictable. You'll also have been fluctuating. Both of those would lead the algorithms to overestimate.

    Also, keep in mind that the calories burned are usually figured by an average size male. Unless you program weight, gender, and age- it will most likely be on the high side . I've used my HRM for triathlon training for years and it's what I consistently see.

    help!

    What kind of HRM is it? Chest strap type is a lot more accurate than the optical or wrist sensor types (and those often don't take data as frequently).

    I don't know if you run or have tried to run recently, but I try to compare my effort to running when I'm trying to figure out if a calorie burn is reasonable. Average person burns 100 calories / mile. An overweight/untrained person might burn between 125-150 calories/mile. So if I assume 135 calories / mile that would be like running 2.75 miles.

    In the past I have used an elliptical for like a half hour and the machine will say something crazy, like I burned 450 calories in 30 minutes. But then I think to myself, did that feel like running more than 3 miles? No. So I probably didn't burn that much. However, if you were lifting books and carrying them around, that is a really great start to some good strength training. Strength training won't burn as many calories per minute as straight up cardio, but building (or maintaining as we lose) muscles will help us burn more calories as we get down to goal weight, and just make us stronger and more capable all around. Also the more activity you can squeeze into your day, the higher your TDEE, the better your burn, and either the faster you will lose weight or the more you can eat if you are trying to maintain. So keep it up!

    Calories running is a simple function of weight and distance. 100 calories per mile for an "average" person means "average" equals just under 159 pounds.

    That relationship does not hold up for other activities. Walking, running, lifting, yoga are very different from a biomechanical perspective so the perceived effort to caloric burn is not a constant.

    The extra burn created by new muscle mass is in the low single digit per pound of new muscle per day range. For females eating at a deficit, that isn't a factor.

    okay thank you all. it was a polar hrm. with a chest strap.
