Japanese Women’s Gym Hero Banner Prompt — Clean & Airy

Generate a polished, feminine gym ad hero banner with a trainer-assisted workout scene in bright, private setting with soft natural light—ideal for landing pages targeting women 30–40. Use it as a Concept Art starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, style, canvas, scene, text, layout, and design. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
