How to read BMI

BMI is a quick screening metric based on weight and height. It is useful for trend tracking, but it does not directly measure body fat, muscle mass, or health status by itself.

  • Weight (kg): your current body weight.
  • Height (cm): your body height in centimeters.
  • Age + gender: included for context in the result display.

Example: 75 kg and 175 cm gives a BMI around 24.5. Use this as a reference point, then combine with waist, training performance, and lab/clinical context.
