Thank you, this is what I constantly say. For population statistics, BMI is nigh perfect, since it's much easier to gather than more accurate data points, and the number of exceptions are super small.

I know very fit people that still fall well in the BMI 20-25 range. Most around 23. You have to be very focused on natural bodybuilding for years if you want to become an outlier on BMI.

Or some combination with being super short or super tall. But this again affects a tiny minority.
