Determining an Ideal Body Weight helps you set realistic fitness goals and understand your body's healthy range based on the Body Mass Index (BMI) standard.
Health Standards:
This calculator uses the World Health Organization (WHO) BMI guidelines to determine the weight range where your health risk is statistically lowest.
Fitness Tip: Muscle is denser than fat. If you are an athlete or highly active, you may naturally fall above this range while remaining perfectly healthy.
