What the result means

BMI is a broad body-size indicator. It is useful for general fitness planning but does not distinguish muscle from fat.

BMI = weight in kg ÷ height in meters squared.

Athletes with high muscle mass may have a high BMI without having excess body fat.

Example calculation

A person weighing 70 kg at 175 cm has BMI = 70 ÷ 1.75² = 22.9.

Tips for better results

  • Use BMI with waist size or body fat percentage for better judgment.
  • Do not set aggressive weight goals from BMI alone.
  • Strength athletes should focus on body composition as well.

FAQ

BMI can overstate risk for muscular people because it does not separate muscle mass from fat mass.

A normal BMI range is a common target, but your best goal should also consider strength, waist size, and health status.

How much weight do I need to lose to reach a normal BMI?
