BMI doesn't distinguish muscle from fat, so it reads high for many strength athletes. Pair it with the body fat calculator for a fuller picture.
These calculators give population-level estimates for healthy adults. They aren't medical advice — talk to a doctor or registered dietitian before making significant changes, especially if you have a health condition or are pregnant.
