Not for the person arguing oppositely, but for everyone else, let me in a perhaps different way make a couple of points:
- In the vast majority of cases – everywhere except where DEXA is used – a given bodyfat percentage is NOT a fact. While ordinarily Thibaudeau saying a thing related to bodybuilding would correspond to a thing being a fact, or let’s say the Pope making a statement on Catholic doctrine would correspond with being a fact, this is NOT the case with “bodyfat percentage” statements when measured by anything but DEXA.
So it does make a substantial difference whether a person’s, for example Butt’s, “7.5%” bf means as in Thibaudeau’s picture, or as is often calculated by for example the Jackson-Pollock equation and 7-point skinfold measurement on an individual who is only moderately ripped or even only well-cut (or what I mean by those terms anyway).
Since DEXA is NOT used for either the subjects of Mr Butt’s analysis, or for pretty much anyone involved in the discussion (unless Coach Thibaudeau used it) we are not talking about facts with regard to bodyfat percentage, but very fallible and variable estimations.
Why do I give credit to my estimations? Well aside from having measured a lot of people in the past (using Jackson-Pollock), I had extensive discussion on this with the University of Florida professor who, in the Exercise Science department, was the go-to person in that regard. As well as having measured me (6% by hydrostatic, 8% by skinfold in quite ordinary walking around condition, moderately ripped at best, with her judgment being that the 8% value is what most likely would have correlated with DEXA) she had measured very many UF athletes and 6% values by skinfold were very ordinary among for example the sprinters, and it was not unknown for their hydrostatic values to be negative thus illustrating how very fallible these methods are.
I appreciate that Coach Thibaudeau has used and has had used on him methods giving higher numbers. Without DEXA there is no way to know what’s what.
However, by methods that most certainly are as credible as any other, numbers such as 8% by those methods are very ordinary and indeed can be walking-around condition. Coach Thibaudeau’s picture however is not an ordinary walking-around condition.
Nowhere does Mr Butt specify that what he means is bodyfat as determined by DEXA, which is really the only method by which anything is any more than a quite unreliable estimation.

Again the hip and waist structure factor has to be considered. For same arms, chest, and legs, having a waist in the same proportion to these as was the case for Mr Butt’s subjects (Steve Reeves, etc) will generate a lighter weight value. Someone with a more normal hip and waist structured – not as suited to bodybuilding — will weigh considerably more for the same chest, hip, and waist measurements.

Yes, referring to what I consider to be about 8% bodyfat, which is in line with what the UF professor in question considered to be most likely an actual (meaning, corresponding with DEXA) 8% bodyfat, I have met quite a few lifters that were natural and were such weights at such heights as mentioned. It really is not vastly unusual.
To be at the same leanness as Coach Thibaudeau in the picture I posted above and with a bodybuilder-type hip and waist structure and that weight and height as naturals, those I have not met.
Nowhere in the “Butt’s Ceiling” diatribes do I see consideration of these points, or even consideration of the fact that they take weights of dried-out, contest condition bodybuilders and don’t seem to recognize that non-dried out and at let’s say “Bowflex ad” level of bodyfat, which is still impressively lean and really I think about as lean as many Golden Age bodybuilders, they weigh quite a bit more.
A sad part is that the Butt fans are so ignorant as to not even pay attention to what Mr Butt says. He has written plainly, on this board, that there can be outliers (or may have said “there are outliers,” but I can’t recall which) exceeding his equation, and also has written plainly on this board that the reason the particular equation that is used on his Internet calculator was chosen is because he thought it would be the most interesting, being based on the past natural bodybuilders that it is, but he has equations for other types of builds – e.g. with more typical waist and hip structure – that in fact allow considerably more weight in lean condition.
So if they knew what the man wrote himself, they wouldn’t be saying what they do. Casey Butt himself says that athletes can be bigger, for given height and percent bodyfat, than what the “Butt’s Ceiling” boys say.

Sad is that I agree that some people will exceed the ceiling. Most will not however. The majority will not.
