BMI is not a good measure for people who are athletic but it works well for average people.

The BMI is accurate for athletic people as well. It is only inaccurate for extremely well muscled people, such as sports stars that use steroids. For 99% of all cases, it's a good unit of measure.


 I disagree, I have a bodyfat percentage of around 20 and my BMI is 32. BMI is bullshit, it takes into consideration nothing like water/liquid balance, musclemass or heavyset ligament and muscle conjoinments (they can actually add quite a few pounds unlike a heavy bone structure which would add only 5-10% skeleton weight, truly trivial). One of my best friends' brother is a proffessional ski jumper and he has a normal BMI of 19 despite having less than 6% bodyfat. I'm currently schooling myself in fitness and nutriton to become a PT and one of the first and most repeated lessons we have is to never make use of BMI, it takes into account no factors of bodily composition, and is as such a very unreliable measure for a broad part of the populace.
