We are lucky enough to have bought an Zephyr HxM Bluetooth Heart Rate Monitor and tried it out today.

My C25K run on a treadmill, consists of me walking very briskly for 16 minutes (3 MPH) and running for 15 minutes (4MPH)

Current weight 227 lbs

According to MFP I have burnt around 200 calories, where as the heart monitor said 520 calories !

Which is right ?

    If someone at a carnival eyeballed you and guessed your weight, and then you stepped on the scale, which number do you think would be more accurate?

    ^^Awesome^^

    The HRM of course is more accurate. MFP is a guess.

    Your HRM is right. I don't go by the entries on MFP because they are someone elses.

    HRM with a chest strap...so long as your settings are accurate.

    I trust my HRM more because MFP is kind of in the general amount by weight of different people. The HRM is actually going by my heart rate & how much effort I'm putting into it.

    HRM.. but only if it takes your age, weight, height and gender into account.. If it doesn't, then MFP would prob. be safer.

    My stupid HRM doesn't calculate calories, so it was a complete waste of money. Lesson learned. But I wonder of my phone C25K app, or MFP, which is the more accurate?

    ETA: if anyone is interested in guessing!

    I'll have to try a Kettleworx workout and see what I get on my HRM. Last kettlebell workout I put it under MFP Strength training and for 20 minutes of sweat and tears had 77 calories burn which I thought looked low. I'll look forward to seeing what Zephyr says :)

    It does take my age, weight and gender into account and it has a chest strap. I'll have to remember to alter my weight as it changes.

    I would say... neither. Probably a little more than 200, but less than 520.

    You covered almost two miles. I'd find it very hard to believe that you burnt ~260 calories per mile, unless you had the incline on the treadmill cranked up to the ceiling.
