SO I decided to wear my hrm all day today and just went about my normal day, desk job, vacuumed 3000 sq foot house, cooked, just normal stuff. I weight 141, 5'2, and my hrm says I have burned 2126 calories in the last 10.5 hours. Sound about right to you??? TIA

    Heartrate is a decent indicator of calories burned during steady state cardio. As such, HRMs are not good at measuring anything else.

    Sadly any HRM is not meant to be worn 24/7 so any readings you get will be wildly off. If you want something that tracks daily activity you will need to look into a Fitbit or Polar Loop or some other all day tracker

    The newer Polar wearables ARE meant to be worn all day, and combine activity tracking with exercise tracking. Which unit are we actually taking about, out of curiosity, and did you mean that you wore the HRM band around your middle all day, or just the wrist unit (which, technically, is not the HRM)? But regarding the accuracy - well, the company certainly says they are accurate :) But, they're basically just fancy calculators trying to make sense out of the data they receive. For your height and weight, 2126 seems high for 10 1/2 hours. I wonder if it read all that vacuuming as running, with the arm going up and down the way it would.

    I can sit in the bleachers for 2 hours after working out, and my heart rate monitor will tell me I burned 1000 calories. Yeah right. I wish! (I don't do it intentionally, I just sometimes forget to turn it off)

    HRM's in general are meant to be used for steady state cardio with no intervals.

    Activity trackers such as a fitbit will track daily activity and adjust your calories accordingly.

    I'm 5'2" and think that that is very high. My fitbit gives me around 1400 in a day, which is also too high- for me. MFP tells me 1200 calories a day and that seems accurate for me based on my slow weight loss over 4 months.
