IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the scene. The person's identity must remain fully recognizable with accurate facial structure, expressions, and body proportions.

TRANSFORMATION DESCRIPTION:
Transform the person into a fitness enthusiast performing a workout in a modern gym. Place the subject in a realistic gym environment with appropriate athletic clothing. The person should appear to be engaged in a workout activity such as lifting weights, using gym equipment, or performing a fitness pose. The transformation should look natural and authentic, as if the photo was taken during an actual gym session.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic, high-quality fitness photography
- Lighting conditions: Dynamic gym lighting with a mix of ambient overhead lights and accent lighting. Slight rim lighting on the subject to separate them from the background. Natural skin texture preserved.
- Color palette: Vibrant but realistic colors typical of a modern gym. Slightly desaturated background to keep focus on the subject. Cool tones with warm accent lights.
- Background treatment: Modern gym environment with visible equipment (dumbbells, barbells, weight plates), mirrors on walls, rubber flooring. Background should be slightly blurred (bokeh effect) to emphasize the subject while maintaining recognizable gym atmosphere.
- Attire: Professional athletic wear appropriate for the workout type (gym shorts/t-shirt or tank top for men, leggings/sports bra or athletic top for women). Clothing should fit naturally and match current fitness fashion trends.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and body
- Professional quality fitness photography
- Natural skin texture and muscle definition
- Realistic fabric textures on clothing
- Cinematic depth of field
- Aspect ratio: 1:1 or 4:3 (square or portrait orientation recommended for gym photos)

NEGATIVE PROMPT GUIDANCE:
