Häufige Fragen
Is BMI accurate for athletes and muscular people?
BMI does not distinguish between muscle and fat mass. A muscular individual may have a high BMI while being very healthy. For athletes or those with significant muscle mass, body fat percentage, waist circumference, or a DEXA scan provides a more accurate assessment of body composition.
