Frequently Asked Questions
What is BMI?

What is the normal BMI range?
According to WHO standards, 18.5 to 24.9 is normal weight. Below 18.5 is underweight, 25 and above is overweight, and 30 and above is classified as obese.
What are the limitations of BMI?
BMI does not account for muscle mass, body fat percentage, or bone density. Athletes with high muscle mass may have elevated BMI readings, so use it as a reference only.
