The BMI is perfectly fine for adults, and is almost never a misleading measure. Even if you are athletic and well muscled, it still applies, and in that case, you can still be within your healthy range. The range is plenty large.
If you are an adult and you think the BMI is misleading, you are probably in denial about your own shape.
[edit] it seems people like to use examples like professional football players, who litterally add 30% to their body weight in muscle. There are two issues here: these people are almost certainly using HGH to attain this amount of mass, and the BMI is still relevant in that muscle weight is approximately as taxing on your heart as fat weight, pound for pound. Despite the fact that you may not want to lose the muscle weight, you can still be over weight.
IGN is simply incorrect.
