Restage my photo as a fitness portrait. Keep my build as it is in the photo — do not change my body. Setting: a real gym with equipment out of focus behind. Hard directional light from one side with deep shadow for contrast and definition, a cool rim from behind. Athletic wear that fits. Mid-action or settled between sets, not posed for the camera. Slight desaturation, strong contrast, a touch of grain. Half-body framing. Keep my face, bone structure, natural skin tone and identity exactly as they are in my photo — change the styling around me, never who I am. The result must read as a real photograph: natural skin texture with visible pores, believable light direction and shadow falloff, correct anatomy and hands.
“Use it” opens the editor with this prompt already loaded — add your photo and generate. Copy works anywhere else: ChatGPT, Gemini, Midjourney.
If you do want a build change, the Muscle Generator app has a Build control rather than leaving it to the wording.
