Fat-Free Mass Index (FFMI)
Calculate your FFMI to assess your muscular development relative to your height and fat mass.
The Fat-Free Mass Index (FFMI) is used by athletes to track muscle gains over time. It provides a more nuanced view of muscularity than the standard BMI.
Tracking FFMI helps you understand your body's potential for muscle growth and ensures your training and nutrition are effective. Focus on steady, sustainable increases in FFMI for peak physical performance.
Privacy: Muscularity data is strictly local to your device and is never uploaded to our servers.
