I found it difficult to achieve a pose where the body bends into a bridge-like shape, curving like a bow, with base_v1. This LoRA was trained on 67 training images depicting curved bridge poses from a variety of viewpoints.Applying the LoRA allows for more flexible and pronounced bridge poses. It can also produce poses where the subject remains standing in a relatively straight posture while bending only the upper body backward, similar to a JoJo pose.
