LBM Calculator

Introduction

The LBM (Lean Body Mass) Calculator estimates the amount of body mass that is not fat — including muscles, bones, water, and organs. It is used in fitness and medical contexts to assess body composition more accurately than weight alone.

Key formulas:

- For Men: LBM = (0.407 × Weight in kg) + (0.267 × Height in cm) – 19.2

- For Women: LBM = (0.252 × Weight in kg) + (0.473 × Height in cm) – 48.3

- These equations are derived from the Boer formula, which provides reliable LBM estimates for both genders using weight and height.

Conclusion

The LBM Calculator is a helpful tool for fitness enthusiasts, athletes, and healthcare professionals who want a better understanding of body composition. It is often used alongside body fat percentage and BMI for a comprehensive health profile.
