Is BMI accurate for athletes?

BMI is a poor indicator of body composition for athletes. Muscular athletes are often classified as overweight or obese despite having low body fat. Use body fat percentage methods for athletes.

What are the BMI categories?

Underweight below 18.5, Normal weight 18.5-24.9, Overweight 25-29.9, Obese Class I 30-34.9, Obese Class II 35-39.9, Obese Class III 40 and above.

What should athletes use instead of BMI?

Athletes should use body fat percentage, FFMI (fat-free mass index), or waist-to-height ratio for better body composition assessment.
