1. BMI Ranges Explained
BMI groups scores into Underweight (below 18.5), Normal (18.5-24.9), Overweight (25-29.9), and Obese (30+). This standard index relates weight to height to screen for potential health risks.
2. Practical Applications of BMI
While BMI is a useful screening tool for weight categories, it does not directly measure body fat composition or distinguish between muscle and fat mass.
2.1 Limits of BMI for Athletes
Athletes with high muscle mass may have a high BMI score without having high body fat levels, as muscle weighs more than fat.
