FAQ
- Why does the prompt stress high subject consistency?
- To guarantee the Day 1 and Day 30 versions show the exact same person so the transformation looks believable rather than like two different models.
- How can I adapt this thumbnail for a female fitness creator?
- Keep the split-screen and flex pose but change the text to a feminine athletic font weight and adjust skin-tone references in the prompt while retaining the same consistency instruction.
