Hold on a second now. 20% is too high to be considered normal? You people are delusional! (not that it’s a bad thing). Lean people on a bodybuilding website aren’t what’s “normal”. You people are the abnormal ones (which again, is good). Even if you aren’t what you’d consider super lean, if you’re like 12% or some shit, you need to understand, that’s not normal. If it were normal you wouldn’t have had to work so goddamn hard to achieve it.
And I’m not talking about normal relative to regular people in society today; I’m talking normal as in genetically/evolutionarily normal for a homo sapiens. Look at wild animals. They don’t have fucking striated muscles. They carry “normal” amounts of fat that animals (including humans) are designed to carry normally.
Of course this argument is academic and doesn’t really matter, but I just wanted to bring it up for you to think about. I think a lot of the leaninites on here have very warped views of what constitutes normal, fat, and lean.[/quote]
I’m not sure “warped” is the right term. What constitutes normal, fat, and lean is very relative at best.
I’ve been places where a man under 30% bf was considered lean (e.g., areas of rural midwest and southeast). I’ve also been places where a man over 20% was considered fat (e.g., east coast metropolitan centers). Neither has a warped view, they’re just relative to the local environment.
For that matter, if we’re talking 1st world countries, “normal” – in the statistical sense – is a very different thing than that of a 3rd world country.
Plus, I don’t think this is a very valid statement: “If it were normal you wouldn’t have had to work so goddamn hard to achieve it.”. “Normal” for a Thai farmer is a lot closer to 12% than for a midwestern American farmer. Personally, I don’t have to work very hard to be close to 12%. I’d have to work very hard to get anywhere near 30%.
Medically, we can talk in terms of numbers, which makes things at least a bit more specific.
Since few of us have access to even remotely decent measuring tools, there’s a lot of talk about degrees of ab visibility as an indicator of leanness. That at least gets you in the ballpark of an estimate.
Because of that, we can say things like “if you can’t see your abs at all, you’re at a higher risk for such-and-such than someone who can see some ab definition”. Correlations still hold merit here, even if we can’t exactly pinpoint where that “starts to see abs” position is on the chart.
