Enter your measurements to calculate your Fat Free Mass Index (FFMI)
Fat Free Mass Index (FFMI) is a measure that evaluates muscle mass relative to height, providing insights into body composition beyond what traditional BMI can offer. Unlike BMI, which doesn't distinguish between muscle and fat, FFMI focuses specifically on lean body mass.
The Normalized FFMI adjusts for height differences, making comparisons more accurate across individuals of different statures. This metric is particularly valuable for athletes, bodybuilders, and fitness enthusiasts who want to track muscle development over time.
How FFMI is Calculated:
FFMI Categories:
Men
Women
Important Notes: FFMI values above 25 for men and 22 for women are considered at the upper limit of natural genetic potential. Higher values may indicate exceptional genetics, enhanced training, or other factors.
Safety Information
This FFMI calculator is for informational and educational purposes only. Results should not replace professional medical advice, diagnosis, or treatment. Always consult with qualified healthcare professionals for personalized health assessments.
Accuracy Requirements
FFMI calculations require accurate body fat percentage measurements. Consider using DEXA scans, BodPod, or other reliable methods for the most accurate results. Bioelectric impedance and visual estimates may provide less accurate FFMI calculations.
