Today I’m going to extend Fitrupt by implementing FFMI computation
Fat Free Mass Index (FFMI)
FFMI is a formula that calculates the amount of muscle mass a person has in relation to his or her height. While similar to the Body Mass Index (BMI), FFMI is a superior method of calculating a person’s body condition and health, even though it is not as popular.
FFMI = Lean Body Mass / (Height^2)
