How it works

  1. Upload your photo

    Upload a clear photo showing the area you want to edit. Good lighting and sharp focus help the AI deliver better muscle definition results. JPG, PNG, WebP up to 7MB.

    Expect: Most edits complete in 20-45 seconds. Complex changes may need 1-2 refinements.
  2. Describe your edit

    Type what you want: 'Enhance muscle definition for a more toned, athletic appearance.' Be specific about details for best results. The AI understands natural language — no technical skills needed.

    Tip: Ask for subtle changes — 'slightly slim' works better than extreme adjustments.

    Copy one of these to get started:

    Arms and Shoulders Enhance the muscle definition in the arms and shoulders for a more toned look
    Abs Definition Add subtle ab muscle definition for a more sculpted midsection
    Overall Tone Add overall muscle tone and definition for a more athletic body appearance
    Fitness Photo Enhance muscle definition and add better lighting to make muscles pop in this gym photo
    4 more prompts
    Subtle Sculpt Subtly improve muscle definition for a naturally fit appearance
    Subtle and natural blend add muscle definition with subtle natural blending that matches the original photo's style
    With specific positioning add muscle definition in the center of the frame with balanced proportions
    Dramatic effect version add muscle definition with dramatic lighting and vivid details for maximum impact
  3. Review the result

    Use the before/after slider to compare results. Check that the muscle definition edit blends naturally with surrounding areas — look for consistent lighting, color matching, and clean edges throughout.
