I was reading an article today where the discussed Lean Muscle Mass Index(LMMI), but they did not say exactly what it meant. It also said that a natural bodybuilder max LMMI is 26 while some one on steriods could reach the upper 30's. I was wondering if anyone knows what this index is and how it is measured. I know what BMI is and I am assuming that this index takes muscle mass into account by using body fat percentage, but I am not sure.
