BMI goes out the window for people that lift weights.
it also makes men and tall people seem fatter than they are. it looks scientific to people unnerved by math but is nothing more than a glorified weight table with the common sense taken out.

True. BMI doesn't account for lean body mass, so many weightlifters and other athletes would be misclassified as overweight or obese. The calculation is intended as a guide to help average Americans determine whether or not they ought to lose a few pounds. For that purpose, it works well. Most Americans are not overweight owing to unusual muscular development, but those who are can disregard the classification.
