The BMI is not a good measure of weight or fat. I’ve said this before and I will say it again. Yes, you could ideally be in the BMI range and have muscle and an extremely low body fat percentage. But if you have more muscle than not, chances are you are actually going to be at the top range of that. BMI does not account for bone mass or density, it doesn’t account for muscles, it doesn’t account for actual body fat percentage or other extenuating factors in general.
It only accounts for the idea that if you are this height, no matter what you should be in this weight range. Luckily, obesity is actually determined by waist circumferences and body fat percentage. It has nothing to do with the BMI. But if you are overweight, it is not fair to judge by the BMI. There are so many factors to weight. But of course, many people still rely on the BMI as their weight bible in some ways. However, with all the measurement tools they now have, they can determine if you are actually underweight despite being regular or overweight on the BMI, which is also a big problem.
