Frequently Asked Questions
No. BMI only calculates total mass. Bodybuilders with massive muscle weight will often be categorized as 'Obese' because muscle is denser than fat. Athletes should use our Lean Body Mass calculator instead.
According to the WHO, a score between 18.5 and 24.9 is considered the 'Healthy Weight' range for standard adults.
