Fit Woman Gym Workout - Squat & Cable Cross Fitness

We need a hyperrealistic photoshoot of the same beautiful, athletic woman, fit and toned, in a modern fitness gym. She's wearing a black sports bra and black gym leggings. The first shot is a mirror selfie, capturing her back as she turns slightly, one hand holding her phone, the other on her hip, with a neutral, confident expression. We want soft, even gym lighting, emphasizing her defined back muscles in the clean mirror, with sharp focus.

Next, we need a side-angle shot of her performing a proper squat, feet shoulder-width apart, hips low, back straight, with a focused expression. Bright studio lighting should highlight visible muscle engagement and dynamic tension, with realistic shadows. Finally, a front three-quarter view of her doing cable crossovers on a dual machine, arms extended, slight forward lean, determined expression. Use high-contrast sport lighting to show defined shoulders and chest activation, with visible cable tension and ultra-high clarity. Maintain a clean, modern fitness palette and medium-shallow depth of field throughout.
