<h3 id="update">Update </h3>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 3Update 06/13/2026: Version 3 for Pony addedThis 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 <a target="_blank" rel="ugc" href="https://civarchive.com/models/1366203/royal-blend-xl">Royal Blend XL V3</a> model.But it also works very well with <a target="_blank" rel="ugc" href="https://civarchive.com/models/827184/wai-nsfw-illustrious-sdxl">WAI-NSFW-illustrious-SDXL</a> and <a target="_blank" rel="ugc" href="https://civarchive.com/models/1223540/hdarainbowillus">HDA_Rainbow_Illus</a>.Please see below the new prompt settings (trained tags are marked in orange letters):Recommended strength: 0.6-0.8A 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)<h3 id="breast-types:">Breast types:</h3>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 shapeFlat chest does what it says and gives the character a flat, muscular chest<h3 id="poses:">Poses:</h3>Victory pose: Victory Pose, arms raisedDouble 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.<hr />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-msclRecommended promt: hyper-mscl, muscular female, hyper muscles,
