The scanner looks at the same visual cues a coach uses to judge body fat: how clearly your abs and obliques show, the shape of your waist, and muscle separation. You get your body fat range, your category, and how many abs show.
Stand facing the camera in good, even light. Keep your chest to waist in frame.
The scan reads ab definition, oblique lines, and waist shape to estimate your body fat.
Scan weekly in the same pose and light. The trend matters more than any single scan.
Where does your result fall? These ranges follow the American Council on Exercise (ACE) categories.
| Category | Men | Women | What it looks like |
|---|---|---|---|
| Essential fat | 2–5% | 10–13% | Stage-lean, extreme definition |
| Athletic | 6–13% | 14–20% | Visible six-pack and obliques |
| Fit | 14–17% | 21–24% | Ab outline, flat stomach |
| Average | 18–24% | 25–31% | Little ab definition |
| Above average | 25%+ | 32%+ | No visible abs |
Essential fat is the minimum needed for health. Do not aim to stay at that level.
