logging exercise

Hello MFP Friends,

I have a question regarding logging exercise. I have been logging my daily exercise with the MFP link. Recently I bought new workout dvd's and had no clue how to count them towards burning calories. I went and bought a heart monitor that tracks calories burned. What the monitor reads vs logging with MFP is way different. A 30 min low aerobic workout on the MFP link says I only burn about 250 calories vs the monitor reads 550. Which tool should I trust?

    The heart rate monitor. 550 does sound a bit high, but it was a new workout for you. After you've done it a few times the number should level out a bit. Also, MFP can't know how hard you're working .... they don't know your resting heart rate or your "working" heart rate.

    You can't trust all HRMs, some are better than others. Does yours have a chest strap or is it watch only? Brand/model?

    550 sounds really high, especially for 30 minutes of what you're describing as low aerobic (meaning low impact I assume). If you plan on eating back the calories, I'd either go with the lower reading from MFP or split the differenct and log it as 400.

    When in doubt, go with the lower number.
  • Although it's tempting to log the highest number and go with that, like a poster above said there's no 100% accuracy depending on the model of HRM.

    If you log the highest number, try to eat no more than 50% of your exercise calories. This allows you wiggle room and ensures you don't go over your cal goal. :)
