Health Tools

Whether you are setting a weight goal, planning a training cycle or just curious about how your body compares to clinical norms, these calculators expose the math behind common health metrics. BMI follows the WHO standard, TDEE uses the Mifflin-St Jeor equation (the most validated formula in clinical nutrition), and the body-fat estimators use the US Navy circumference method. None of them replace a doctor, but together they give you the same numbers a clinician would compute by hand.
