Update

Version 4.2
This Version is a nearly complete overhaul from the previous versions. I removed many old training material and added new ones to improve the depiction of the muscles. They now look more "realistic" and less like a mutation.

For now, I removed training material for the poses, flat chest and pregnancy, but might add some of them with new training material back in a future release.

Version 3

Update 06/13/2026: Version 3 for Pony added

This version is a total overhaul and I made several improvements to the depiction of the muscles, abs, obliques and especially the breasts. And I also added some Bodybuilding poses.

During my testing I noticed that it works unintentionally well with my Royal Blend XL V3 model.

But it also works very well with WAI-NSFW-illustrious-SDXL and HDA_Rainbow_Illus.

Please see below the new prompt settings (trained tags are marked in orange letters):

Recommended strength: 0.6-0.8

A Highres fix is recommended to get better results of the fine details.

Trigger: muscular female, hyper muscles, thick thighs, biceps (you can also omit hyper muscles and thick thighs in order to make them less big)

Optional:

abs, obliques, veiny muscles (adding these makes the muscles and abs more detailed. And sometimes a bit too much, see my preview pics 😊)

Pregnant (I also added some training material to make better looking pregnant muscular women)

back muscles, veiny muscles (use these when making a pose from the back)

Breast types:

I trained this model with 3 different types of breast shapes:

Sagging Breasts gives the the breasts a more „natural“ look.

Breast Implants gives the breasts a round, spherical shape

Flat chest does what it says and gives the character a flat, muscular chest

Poses:

Victory pose: Victory Pose, arms raised

Double biceps pose: double biceps pose, flexing both arms (not really necessary since just writing „flexing“ does mostly the same)

Single biceps pose: single biceps pose, flexing one arm (works, but sometimes needs several tries to work)

I plan to add more poses in a future release.

This is my 2nd try on a Hyper Muscles Lora and it now creates huge muscles as intended.

It worked quite well in my tests and clothing Loras also work to some degree.

Trigger: hyper-mscl

Recommended promt: hyper-mscl, muscular female, hyper muscles,
