Gemini Image (Nano Banana) Prompt Generator for Fitness & Health Coaching

Gemini Image (Nano Banana) understands full sentences, so the prompt reads like a photographer's brief: subject, setting, lighting, composition, mood and where the image will be used.

Every prompt is built from the same modular parts — role, task, context (your audience and details) and output format — then rendered in the style each AI follows best. Change the AI in the drop-down and the same request is rewritten instantly.

• Describe the scene conversationally — Gemini can keep editing the image across turns.
• Upload a reference photo to keep a product or person consistent.
• State the aspect ratio explicitly.

Choose a prompt type for fitness & health coaching; each comes with an expert role, context rules and an output format:

• Fitness photo — for example “a woman performing a kettlebell swing”.
• Exercise illustration — for example “how to do a correct bodyweight squat”.

Example output for Gemini Image (Nano Banana):

Create an image of a woman performing a kettlebell swing, set in a modern gym with natural light. Style: athletic lifestyle photography. Lighting: dramatic side light that defines the muscles. Composition: low angle, subject mid-movement. Mood: powerful and motivating. Details: focused expression, teal and black colour grade. It will be used for an Instagram ad for a gym membership, so use a 4:5 aspect ratio. Avoid: distorted anatomy, extra limbs, text.
