you are correct, The bmi does not fit well for some body types. Because it only takes weight - and not the source of the weight (bone/muscle/fat/water).
For example, lets take the typical NCAA running back. VERY strong and lean, but also pretty short. A typical size for a running back would be 5'8" and weigh 205 lbs. According to BMI charts, this person would be obese! But we all know that it is the exact opposite.
For most people, however, the bmi is a reasonably good source for getting a rough idea of a range. It is just something kind of quick and easy - at the price of accuracy. But for body builders/people with alot of muscle, people retaining fluid - perhaps due to liver (ascites) or kidney problems, or very big-boned or small-boned people - the bmi is not accurate.
