I am utterly baffled by the cardio load 'feature' on my FitBit. I get a cardio load score for a light walk where my heart rate hardly goes into the light exercise zone, but nothing at all for a pretty vigorous 25-minute Spin session of constant high heart rate. Can anyone explain how that can be the case?
As a result i can have had a good cardio workout but still have the app pestering me to increase my cardio load. No sense whatsoever.
