Create a professional photorealistic fitness photograph of a young athletic woman around 19–24 years old performing a single-arm dumbbell row beside a workout bench. She wears a fitted black athletic crop top, dark gray leggings, and clean training shoes. One hand and knee rest naturally on the bench while the opposite hand pulls a dumbbell upward in a controlled movement. Her posture should be anatomically correct, with realistic engagement through her back, shoulder, and arm. Position the camera at a front three-quarter angle so her face remains clearly visible despite her exercise position. She should turn her head naturally toward the camera with a focused, confident expression. Use soft frontal fill lighting across her face so her eyes, cheeks, forehead, and jawline remain bright and sharply detailed. Use subtle side lighting across her body to create realistic definition. The background should feature dumbbell racks, benches, cable machines, weight plates, and mirrors with gentle depth-of-field blur. Add subtle post-workout perspiration. Preserve realistic hands, fingers, wrist positioning, natural body proportions, skin texture, individual hair strands, authentic fabric folds, and believable gym equipment. Use professional 50mm fitness photography, cinematic depth, natural color grading, balanced exposure, realistic shadows, crisp facial focus, and 8K photorealistic detail.
