Request a Wan2.1 LoRA on our Discord, and we will train you and open-source it for free.
Join our Discord to generate videos of the Muscle Show-off Effect LoRA for free.

Wan2.1 14B I2V 480p v1.0:
Trained on 30 seconds of video comprised of 12 short clips (each clip captioned separately) of people showing off their muscles. This was trained on the Wan.21 14B I2V 480p model.

The trigger word is: 't2k1s takes off clothes revealing a lean muscular body and shows off muscles'

See below for some prompt examples that worked well for me. You can also check the videos I've posted here for the captions that were used to generate them. For each video the input image is just the first frame.

Recommended Settings:
LoRA strength = 1.0
Embedded guidance scale = 6.0
Flow shift = 5.0

Here's a link to the Wan2.1 I2V LoRA inference workflow I used to generate these videos: https://huggingface.co/Remade/Squish/blob/main/workflow/wan_img2video_lora_workflow.json

This is a slight modification to Kijai's version, with the main difference being the addition of the WanVideo Lora Select node, connected to the 'lora' field of the WanVideo Lora Select node. Find Kijai's original workflow here:

Prompt Examples:
A man in sunglasses and a black bandana stands in an urban environment, then t2k1s takes off clothes revealing a lean muscular body and shows off muscles, looking towards the camera.

A young man standing in front of an orange background with his hands in his pockets, then t2k1s takes off clothes revealing a lean muscular body and shows off muscles, looking directly at the camera with a slight smile.

Let me know if there are any questions, I'll be happy to help
