Fitness Age and BMI

Gaynier said:

You should consider using waist/hip and other measurements rather than rely on BMI.

You can use Fat% instead of BMI. To have it done comfortably, you'd need the Index scale for that, otherwise you'd need to import the Fat% in a small CSV file regularly, since it cannot be entered directly through the interface.

But the Index scale will probably think he's too fat to.

But Garmin could make it easier than that, unless their intention is to get people to buy their scales! I found an online body composition calculator that is based on method used by the Navy Seals;

Garmin could have us enter the same body measurements and perform the same calculation. Easy peasy. Clearly I don't need to lose weight.

Sure they could, but we cannot help you with that. You'd need to suggest it to them at Share Ideas | Garmin. In the time being, before they implement it (and it may take couple of years, by experience), you can still use the proposed ways - either the Index scale, or the CSV import.
