#ai muscle tutorial

Thanks! I use Bing’s image creator, and the tricks are constantly evolving. What worked three months ago may not work today. Currently, I use a prompt something like this:

shocking polaroid, gritty and desaturated image, side view, friendly masculine bodybuilder on stage at a roidgut convention flexing his disproportionately huge muscles for the crowd, handsome, confident, defined jawline, cleft chin, wearing a t shirt, jeans, sneakers, enormous octuplet pregnancy belly the size of an orb sticking out twenty feet, his belly is too big for him to reach around, his fans cheer for him as he pushes his belly toward the crowd

To get an image something like this:

In the interest of community and education, here is an example.

These four images were the result of one submission of one prompt - I didn’t have to wrestle the machine for them at all. The prompt is:

underexposed Polaroid, side view from far away, two Icelandic bodybuilding bros facing each other submerged near a hot spring, enormously muscular, golden light, loving embrace, buzzed blond hair, relaxed, unbelievably enormous muscles, muscle morph, leg muscles like enormous heavy water balloons, enormous muscular arms, high body fat, leaning against each other

Now be warned, this is a bit of a jenga tower. Moving things around too much may break it. I’d recommend writing your own from scratch but stealing specific key phrases, modifying and evolving those, see what works best for you.

Thanks to @thespacewerewolf for the “near a hot spring” trick to get them into a hot spring, and to @zangtangimpersonator for the water balloon / weather balloon comparison trick, which is a Swiss Army knife of a prompt for anyone who likes big round shapes.

wide, side profile full body shot, natural light, handsome 34 year old Portuguese ceo gives presentation to board of directors, blue button up dress shirt, black dress pants, black shoes, confident expression

Then I added the phrase

muscular backside

Accepted on first pass, 4 results returned, all underwhelming. Prototypical example:

So I modified it to be

muscular backside resembling a giant water balloon sticking out

Since water balloons sticking out have done such excellent work for me lately. Prompt accepted first try, 1 result returned.

Wow, ok, that’s a lot, probably too much. Let’s dial it back. Let’s delete the water balloon sticking out and instead have it be

enormous muscular backside

Risky because of the size modifier. But hey! Accepted first try, two results returned. And they’re NICE.

Definitely the best so far by a big margin. But the rest of him is a little underfed, isn’t it. Let’s go back to the top of the prompt and add “muscular” so that it reads

handsome muscular 34 year old

Accepted first try, two results returned.

Huh. I mean it’s still good, particularly the second one. But at best a lateral move, and at worst a downgrade.

How about we risk another yellow alert term and add “spherical” in front of enormous muscular backside?

Accepted first try, only one result, but those who dare not grasp the thorn should never crave the rose

Exquisite. But my brain says why stop there? Let’s go back to the top and modify “muscular handsome 34 year old” to be “bulked up handsome 34 year old”

Accepted first try. One result. My god. It’s alive.

I own the plane bro, and if I want you to fuck me at 30,000 feet, you’re gonna fuck me at 30,000 feet.

(This prompt:

rear view, natural lightning, full length photo, grotesquely muscular 600lbs 19 year old Canadian bodybuilder, staggeringly broad back, impossibly overdeveloped rounded lower back muscles, freakishly rounded quadriceps and hamstrings, spilling out of an airplane seat in Paris

I don’t know why Paris makes it safe, but Paris makes it safe. This probably will change soon enough but for now, if you’re trying to sneak something weird past the robot guard, just say it’s in Paris.

Et maintenant (les visages grotesque sont eternal, quel dommage)

Confounders are what I’ve taken to calling mundane phrases that help slip the fetish stuff past. A phrase like “taking a book off a library shelf” or “waiting for his coffee at Starbucks” or “wearing an Atari t-shirt” or “in a safe Canadian suburb in June.” These seem to muddy the waters in a way that helps “our side” against the fun-hating censors. Often, if you’ve got a prompt that’s on thin ice, removing one small Confounder can tip it into ban-land. For example, you’ve got a prompt that works, but “wearing aviator sunglasses” is one of your confounders. You want to see his eyes. If you delete that phrase, suddenly the entire prompt is rejected.

This is also a way to find out what terms are weighted. I’m convinced it’s not a binary at this point. I’ve used phrases like “muscular glutes” safely in prompts that are otherwise very boring and non-sexual. Similarly, things which you’d never guess to be objectionable clearly have some small NSFW weight to them - adding a phrase like “bulked up” or “side angle” to a successful but very risky prompt has turned it into a rejected prompt, when demonstrably “bulked up” and “side angle” are fine in other contexts.

“Bulky” and “bulked up” in general must have had their “weight” increased (haha) very recently, because they have absolutely been sinking prompts that look quite tame to me before I submit them.
