Hong Meiling from Touhou Project
Meiling is often drawn in a martial arts stance. This Lora does a surprisingly good job of recreating that, although it struggles with hand poses (as you would expect). Training images of this sort were tagged with "dynamic pose, fighting stance". Add this to your positive (or negative) prompt if you do (or do not) want this in your output.
The training set only included anime-style images, but it seems to work well with photo-realistic models too.
