I have a Garmin Forerunner 50 & when I do a gym workout, toning class or Kickboxing & I download my workout to the Garmin connect web site my Forerunner 50 does not record any calories burnt. I'm finding this quite annoying. Can someone tell me what I'm doing wrong, or if the Forerunner 50 does not have this function. If this is so then can someone tell what Garmin watch product do (I have a Garmin 500 & if I use it during a gym workout it records calories burnt, but it looks very wanky on my arm).
The FR50 does not calculate calories from HR. I don't own an FR50, but the calorie consumption is likely based on distance, and is most likely optimized for runners.
