Rate My Abs

The AI looks for visible ab separation and oblique definition in your photo, weighing how much lighting and pose likely flattered or hid the true picture (harsh side-lighting can create shadow definition that isn't really there, and a braced pose reads more defined than a relaxed one), then describes your current definition stage in plain language.

A front-facing, well-lit photo with even lighting (avoid strong side-lighting or shadows), standing in a natural relaxed stance rather than flexed or braced, gives the most accurate read.

Visible ab definition is affected by body fat distribution, lighting, pose, hydration, and even time of day — the same person can look meaningfully different in two photos taken minutes apart. Treat this as a snapshot of one photo, not a precise or medical measurement.

Visible abdominal definition becoming a mainstream fitness benchmark tracks closely with the rise of gym-selfie and fitness-influencer culture in the 2010s, but the underlying idea is older: bodybuilders have used visible ab separation as an informal leanness indicator for decades, since ab definition reliably starts to show at lower body fat percentages than most other muscle groups.

These ranges run roughly 8-10 points higher for women due to typical differences in essential body fat, and genetics (particularly how fat is distributed and natural muscle insertion points) mean two people at the same body fat percentage can show noticeably different ab definition.
