When I was in the best shape of my adult life, I weighed 175, with 10% body fat (measured with calipers) and a size 30 waist. I wasn't overly into lifting weights but did a lot of cardio. My BMI was 30 - obese.
5 years later. I do about 3 hours of cardio a week, I weigh 185 and my waist is about 32. My BMI is 31.8. No doctor has ever looked at me and said I need to lose weight.
BMI is completely bunk in my case.
