Frequently Asked Questions
How is BMI calculated?
Weight (kg) ÷ height (m)². Categories: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30+ obese. It is a population screening tool, not a diagnosis.
What are BMI's limitations for fitness clients?
It cannot distinguish muscle from fat — muscular athletes read "overweight" regularly. Pair it with waist circumference, body composition, and performance markers for a real picture.
Should trainers use BMI in client assessments?
As one baseline metric among several, useful for tracking direction over time. Frame it carefully — progress photos, measurements, and strength gains motivate better than a single index.
