Heavy weight Body Builder/ professional athlete The above FFMI chart shows FFMI ranges for men, here is a table that shows FFMI ranges in women. The values above 28 show person using steroids as it is not possible to achieve naturally.The values between 26-27.9 show a person might be using steroids but it is possible to achieve this naturally.Heavyweight Bodybuilder/ professional athlete The following tables classify the FFMI indexes: Here is the table of scores that can be used by anyone to know where they stand regarding muscle mass and how much they can gain naturally and with the use of steroids. Body height- measured in meters, inches, feet, and centimeters.Body Weight- measured in kilograms and pounds.The fat-free mass index uses three factors to measure muscle mass in body which are: FFMI is not used commonly as BMI but is more precise and used for particular people like Bodybuilders and athletes.
