I’ve been using a Withings scale for the last 4 months. Body fat percentage started at 30% and dropped to 25% over the course of those 4 months. Muscle mass never went above 67% which, according to the scale, is well under the average.
Last week I found out from another TR user that the scale has an athlete mode, it should be used for anyone who exercises 8+ hours a week and has a resting heart rate under 60bpm.
I turned on heart rate mode and my fat percentage dropped to 18% and muscle mass went up to 80%, this has been the consistent reading for the last week. Have I been using the scale wrong this whole time or is the scale borked?
