: BMI = weight (kg) divided by height (m) squared. For example, 70kg and 175cm: BMI = 70 / (1.75 x 1.75) = 22.9.
: A healthy BMI is between 18.5 and 24.9. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.
: BMI may overestimate body fat in muscular individuals. Athletes should consider body fat percentage for a more accurate assessment.
