Frequently Asked Questions

Men: Essential (2–5%), Athletes (6–13%), Fitness (14–17%), Average (18–24%), Obese (>25%). Women: Essential (10–13%), Athletes (14–20%), Fitness (21–24%), Average (25–31%), Obese (>32%). The "Fitness" range is ideal for most non-professional athletes.
What measurements do I need for women?
Women need 4 measurements: height, neck circumference, waist circumference (at narrowest point), and hip circumference (at widest point). Measure in centimeters or inches consistently.
What is Lean Body Mass (LBM)?
LBM is your total body weight minus fat mass: LBM = Weight × (1 − body fat%). It includes muscles, bones, organs, and water. Tracking LBM is more meaningful than scale weight — an increase in LBM indicates muscle gain even if total weight stays the same.
