BMI is bullshit. By that calculation, Arnold was grossly obese in his champion years.
I am built like a minotaur - tall, wide, and meaty. I regularly pump iron, hike, train core, ride an exercise bike, and have no beerbelly/potbelly and drink no alcohol. These guys make me out at BMI of 35, which would put me in the obese category? Please. My blood pressure is normal and I can't remember the last time I was sick. That being said, I'll get a lot of definition if I shed about 20 lbs (which will still put me at about BMI=32, obese!).
Like I said, BMI is bullshit.
