Based on an analysis of some 300 class and overall title winning drug-free bodybuilders and strength athletes from 1947 to 2010 the following equation, predicting the maximum lean body mass someone of a given height and bone-structure can achieve without the use of anabolic drugs, was derived. It describes a “normal” state of nutrition and fluid retention in the trainee. (There is a link at the end of this article to an online calculator based on all of the formulae presented here).
where,
H = Height in inches
A = Ankle circumference at the smallest point
W = Wrist circumference measured on the hand side of the styloid process.
(The styloid process is the bony lump on the outside of your wrist.)
%bf = The body fat percentage at which you want to predict your maximum lean body mass
The above equation, as it was derived from collected data, applies most accurately to individuals of approximately average, balanced bone structures for their heights and average muscle belly lengths. Very thin ectomorphic men can expect to achieve roughly 95% of the lean body mass that the equation predicts. Likewise, very endo-mesomorphic men, men who have disproportionately wide hips, thick shoulder structures and torsos, high natural testosterone levels, exceptionally long muscle bellies or uncharacteristically small joints for their frame size may be able to exceed the prediction by up to roughly 5% in extreme cases (WNBF World Champion and Mr. Universe Rob Hope comes to mind).
As the above equation is intended for bodybuilders in a steady, maintainable state, special adjustments should be made for “bulking” off-season bodybuilders who, due to heavy food and liquid intake, often carry additional pounds of “lean body mass” in the form of fluid retention, labile proteins and contents in the digestive tract. In these cases, a bodybuilder may carry up to 4% additional body weight due to these factors - the predicted body weight must be multiplied by a maximum factor of 1.04 to account for this.
Comparing these body weights to population averages shows that these champions carry 24-26% more lean body mass than the average person of their height and bone structure. A large man such as Reg Park would carry 38-41 pounds more muscle than his average, non-weight training counterpart. A smaller structured man, such as 2006 WNBF World Champion Jon Harris, would carry about 31-34 pounds more muscle than an average, non-weight training man of his height and structure. It is also interesting to note that the absolute level of muscle mass carried by modern drug-tested bodybuilders is not statistically greater than that carried by bodybuilders from the pre-drug era - though modern bodybuilders compete at much lower body fat levels.

But, Casey Butt also wrote that his numbers may be off when it comes to those of African descent.
Not to mention if most winners were of one ethnic background in majority, then it definitely does not represent what all people can do.
