Create a high-end cinematic 3-panel (triptych) fitness editorial poster in a bold black and vibrant yellow color theme inspired by modern gym branding. The design should feel like a premium fitness campaign with strong contrast, clean layout, and powerful visual hierarchy. SUBJECT: A beautiful, attractive, fit young woman (not based on any real person), athletic and toned body, glowing skin, confident expression, strong posture. Hair tied in a sporty ponytail. She looks powerful, focused, and energetic. STYLING: Premium gym wear (sports bra + shorts set) in black with yellow accents, clean white sneakers, minimal accessories like wrist wraps or fitness band. ENVIRONMENT: Minimal industrial concrete studio with dramatic side lighting, deep shadows, and glossy floor reflections. Add subtle gym elements like dumbbells or a vintage boombox. Background should blend black shadows with bold yellow graphic textures, paint strokes, or abstract shapes. 📸 PANEL COMPOSITION (ALL IN ONE IMAGE): Top Panel (Hero Shot): The woman sitting in a relaxed but dominant pose, looking sideways confidently. Text: “BUILT IN SILENCE.” “PROVEN IN RESULTS.” Bottom Left Panel: She is seated or leaning after workout, slightly sweaty, natural athletic look. Text: “NO SHORTCUTS.” “ONLY HARD WORK.” Bottom Right Panel: Standing strong, powerful pose, one leg slightly raised or leaning. Text: “DISCIPLINE DEFINES YOU.” “SHOW UP EVERY DAY.” 🎬 DESIGN STYLE: Ultra-realistic, 4K resolution Bold black & yellow color dominance Modern gym poster aesthetic Strong shadows + cinematic lighting Clean, bold typography (white/yellow contrast) Slight grain for cinematic feel Balanced layout like professional Nike-style ad
