Body Mass Index (BMI)

BMI is a solid starting point for assessing your client’s physique…
But remember, it’s only the tip of the iceberg!

Calculate Your BMI

Enter your data for a quick estimate.

Tip: measure barefoot, standing straight against a wall.

How to Use

  • Enter body weight (kg).
  • Enter height (cm).
  • Click Calculate.
  • The BMI score will appear together with its category (underweight, healthy range, overweight, obesity).
  • A suggested bodyweight range for a “normal” BMI (18.5–24.9) is provided as a reference point for goal-setting.
  • Measure waist circumference at the navel level, right after a normal exhalation.
  • Use the reference table next to the chart to identify your client’s health risk factor and integrate it into your assessment.

Disease Risk (Waist-to-Weight Assessment)

Measure your waist circumference at the navel level, standing, right after a normal exhalation, then check your risk.

💡 A “normal” BMI combined with high waist size = increased cardiometabolic risk.
