A fit young woman taking a mirror selfie inside a busy gym. She is turned slightly sideways, looking over her shoulder at the mirror while holding a smartphone in front of her face. She wears a matching olive green workout set (form-fitting tank top and textured leggings). Her long straight hair has subtle highlights and falls over her shoulders. The gym environment is active and realistic, with weight machines, cables, treadmills, and people working out in the background. The lighting is bright and even, typical of indoor gym fluorescent lighting, creating a natural, unfiltered look. Shot in smartphone style (iPhone), vertical 9:16 composition, mirror reflection visible, casual influencer fitness content. No heavy editing, natural skin texture, slight background blur but overall sharp image. Instagram fitness influencer aesthetic, candid yet posed, high detail, realistic proportions, everyday gym vibe.
