How it works

  1. Upload your photo

    Choose a photo where your arms are clearly visible and well-lit. Sleeveless tops or tank tops work best for accurate enhancement. Good lighting helps the AI understand your natural arm shape.

    Expect: Simple toning: 45 seconds. Detailed muscle definition: 1-2 minutes and may need refinements.

  2. Describe the enhancement you want

    THIS IS THE KEY STEP. Type exactly how you want your arms enhanced: 'tone my arms and add muscle definition', 'slim my upper arms', or 'enhance arm muscles naturally'. Be specific about the type of enhancement. No need to mark your arms - the AI finds them automatically.

    Tip: Use descriptive terms like 'subtle toning', 'athletic definition', or 'natural muscle enhancement' for best results

  3. Review the enhancement

    Check how the arm enhancement looks natural and proportional to your body. Zoom in to see muscle definition details. The AI maintains realistic proportions and skin texture.

  4. Fine-tune specific areas if needed

    OPTIONAL. If you want to adjust specific areas like biceps or triceps definition, tap markers on those areas and regenerate with more specific instructions. Most enhancements look perfect without markers.

    Tip: Markers help when targeting specific muscle groups like biceps vs. triceps

If something looks off

AI changed the wrong area or enhanced something I didn't want changed

Why: The AI couldn't determine exactly which part of your arms you meant to enhance from description alone.

Try: Tap markers on the specific arm areas you want enhanced (biceps, triceps, forearms), then regenerate with the same prompt
Try This →

Tip: Markers tell the AI 'enhance THIS muscle group specifically.' Use them when targeting particular areas like just biceps or just upper arms.

Enhancement looks too fake or overdone

Why: The AI applied maximum enhancement rather than the subtle look you wanted.

Try: Add modifying words to your prompt: 'subtle', 'natural', 'slight' for softer enhancement
Try This →

Tip: Photos with good lighting and clear arm definition produce the most natural-looking results.

Arms look disproportionate to the rest of my body

Why: Enhancement was too strong for your body frame or the photo angle.

Try: Request 'proportional enhancement' or 'natural enhancement that matches my body type'
Try This →

Tip: Front-facing or side-angle photos work better than extreme angles for proportional results.

Only one arm was enhanced

Why: Photo angle or lighting made one arm more visible to the AI than the other.

Try: Specify 'both arms' in your prompt or place markers on both arms before regenerating
Try This →

Tip: Symmetric poses with both arms equally visible work best for even enhancement.

Enhancement looks unnatural or plastic

Why: Photo quality or compression made it difficult to blend the enhancement seamlessly.

Try: Use a higher quality photo with good natural lighting, or specify 'natural skin texture'
Try This →

Tip: Photos taken in natural daylight with minimal filters produce the most realistic enhancements.
