Muscle Proportion Calculations

[GlamLeatherPunk]

A while back--I'm talking a couple of years, most likely--I found a set of formulas for calculating proper muscle proportions, based on the "golden triangle" --a rule of Pythagoras, perhaps. I know it's been published in more than one muscle magazine over the years. Does anyone have any info on these formulas?
Thanks in advance for any help or advice.

It's wasn't based on the golden triangle or anything, but was based on actual mathematics (which I suppose is the same thing)

http://www.impulseadventure.com/weights/ideal.html gives a detailed idea of what to look for (if you don't mind doing a bit of maths!)

I mind doing a bit of math when sitting in front of a perfectly capable calculating engine, so some time ago when the ideal proportions formulas were posted to one of the muscle-oriented Yahoo groups (ooh, quelle surprise, it was the MGS group), I turned the "conversion chart" originally posted into a bit of Perl code to generate body measurements from height/weight values.

Because it's Perl, most of you (those running Windows or default-setup MacOS) won't have the ability to run the script unless you install a Perl interpreter, which is admittedly a lot to ask just to run a throw-away bit of fantasy math. But, hey, I'm on UNIX where Perl is standard equipment, so neener neener. <EG> ...Actually, come to think of it, Perl might be standard on MacOS as well, but you'd have to go into the Terminal to run it... which I hear is scary.

For anyone who's really curious, or aspires to geekitude (if you run Perl on Windows, you've got automatic geek cred) and feels like installing ActiveState Perl in order to run the code, here's a copy of IdealProportions.pl I threw into my geocities account.

Since there's renewed interest, depending how bored I get in the next few hours, maybe I'll finally get around to converting it into a nice chunk of run-anywhere JavaScript and throw it up on the web.

Just for comparison, I thought you guys might like to see the "average man" calculations used for designing seats, doors, etc. in the United States. [The number in the brackets is the Standard Deviation]

Ht - 68.6 in [2.74 in]
Wt - 166.3 lb (Ideal is 148-160)

Neck - 14.8 in [.79]
Biceps - flexed - 12.6 in [1.22]
Forearm - flexed - 11.65 in [.82]
Chest - 37.25 in [2.64]
Waist - 32.3 in [3.31]
Hips - 37.8 in [2.61]
Upper Thigh - 22.00 in [1.88]
Mid Calf - 14.3 in [1.16]

The ideal chart says this man is 2.44 and the differences are interesting.

Since these were calculated the average man's weight in the US has gone up to 189.8 lb. but I do not have the corresponding changes in measures.

well i ran your perl script and hell i'd love to be the stats it spat out.. shame i'm more fat than muscle

Too many numbers!!! *head explodes*

Gonna calculate pi next?

The ideal uncrackable PIN code!!

[diegodominica]

I might be dense and not understand what those numbers refer to but I thought the initial question was asking what the ideal relative proportions of a male would be. Something like chest to waist ratio, chest-thigh ratio, etc. Maybe the person who originated this thread can clarify his intent.

[Geek2Jock]

That would be pi to, what, the 500th? It's a joke on TheMM's comment about too many numbers!
