Cinematic Gym Portrait Prompt

A cinematic, ultra-realistic gym portrait of an athletic young woman with a strong, lean physique and clearly defined abs. She is standing indoors in a modern gym after a workout, slightly sweaty, looking down at her torso while gently touching her upper abdomen/chest area as if checking muscle engagement or breathing. She is wearing a soft pink sports bra and matching pink jogger pants, minimal accessories, no visible branding. Her dark hair is tied back in a low, slightly messy bun, with a few loose strands near her face. Her skin has natural texture and a light sheen of sweat for realism. The environment is a dimly lit gym with treadmills and other people exercising in the background, blurred using shallow depth of field. Background lighting is soft and warm, creating a moody, cinematic atmosphere. Lighting is low-key and directional, highlighting muscle definition on arms and abs while maintaining soft shadows. The image feels natural, candid, and powerful rather than posed. Shot on a full-frame camera, 50mm lens, f/1.8, shallow depth of field, ultra-detailed, photorealistic, high dynamic range, realistic skin tones, cinematic color grading, fitness photography style, Instagram-quality realism, 8K resolution.
