Note for Athletes
BMI was designed as a population statistic — not an individual health measure. It does not distinguish muscle from fat. A 200 lb athlete with 8% body fat and a sedentary person of the same weight have identical BMI scores. If you are muscular or highly active, your BMI likely overstates health risk. Use body fat percentage or waist-to-height ratio for a more accurate individual assessment.
