AI Muscle prompt
Vertical 9:16 clip, 5 seconds. An AI-generated slim young man in a plain white t-shirt stands centred in a bright gym, facing the camera. He flexes both arms and his body comically swells into a huge bodybuilder physique, shoulders and biceps growing, the t-shirt stretching tight. He grins and strikes a double-bicep pose. Static camera, bright even light, playful, realistic, no logos.

Tips for a better result
- A full-body photo in fitted, plain clothes gives the best result.
- Keep clothing on and the tone comedic.
- Use yourself or someone who agreed, never a celebrity.
