I'm soliciting for some advice here for users of Myfitness.com that sync to a Fitbit and workout on an elliptical.

I've noticed, for some reason, when I compare the distance on my fitbit to the distance reported on the elliptical, there is a huge discrepancy, usually 2/10ths of a mile for each mile done.

Now I can understand that there would be variation between the elliptical and the calories burned on the elliptical [because elliptical calorie counters tend to be unreliable], but the distance should be one and the same.

This leads me to believe that my calorie burn is being unreported.

Any ideas on how to adjust/calibrate/compensate for this under-reporting, aside from ignoring it?

Thanks!

You can calibrate your walking and running stride and enter those in your fitbit profile to get walking and running accurate. I am really not sure about distance on an elliptical since it is kind of a made up thing. I know there are those elliptical bikes now, but the machines were giving distance figured before they were available. I am not sure what the elliptical distance is actually based on? I get how they can figure it out for rowing, cycling, skiing and treadmill machines. I am not sure about the calorie burn numbers from elliptials either (speaking of either the fitbit estimate or the machines as they are often reported to be one of the worst for over estimating). I am not anti-elliptical, it is one of my favorite machines when I went to a gym. They are a great low impact full body workout. I am just skeptical to how their distance figures correlate to the real world.

One idea, I don't know how good it is for the calorie burn. If you don't run, you could calibrate your running stride to the elliptical. Look at the thread on stride calibration, you would basically divide the distance covered in your elliptical workout by your steps during the workout. I am not sure how valid it would be, since in a way the movement path is a little more like cycling and the cycling distance involves gliding so stride really doesn't work.
