FFMI calculator
How much muscle you carry for your height, from your weight and body fat.
FFMI 22,3 (height-adjusted)
Lean mass 72,3 kg · Unadjusted FFMI 22,3
How it works
- Fat-free mass is your weight minus fat; FFMI divides it by height squared.
- The adjusted score normalises to 1.8 m so tall and short lifters compare fairly.
- For men, about 18 to 20 is average, 22 to 23 well trained, and around 25 is often cited as the natural limit.
Questions
Can you go over 25 FFMI naturally?
A few genetically gifted people do, but scores well above 25 are uncommon without performance-enhancing drugs.
