Fat-Free Mass Index (FFMI) Calculator

This tool calculates the Fat-Free Mass Index (FFMI) to assess your lean mass relative to your height. By considering your weight and body fat percentage, the FFMI provides a more accurate representation of muscle development than the traditional BMI. It is particularly useful for individuals engaged in fitness or bodybuilding, as it reflects muscle mass independently of body fat.

The FFMI focuses on lean mass, providing a better understanding of your muscle growth. It is an excellent tool for tracking progress and adjusting your training and nutrition decisions.
