How to train checkpoint model?

i collected HQ18895 images. My goal is to train different body styles with accuracy.

Ok there's multiple ways to do this, largely if you go to the ARTICLES section here on CivitAI ther'es some great SDXL articles by SECourses, otherwise my suggestion is to search on Google for best ways to do a Dreambooth or EveryDream trainer run. Not all of them require CONCEPT folders, but just check because every version of doing it is entirely different, and no one way of training is entirely anything more than opinions :)
