How the screen works
Guardians are measured via Waist-to-Height Ratio (0.55 pass/fail), assessed separately from the fitness test. The body-fat ceiling aligns with the DoD corridor (26% men / 36% women).
| Initial screen | Threshold | Result |
|---|---|---|
| Waist-to-Height Ratio (WHtR) | must be < 0.55 | Below passes with no tape test; at or above → secondary body-fat evaluation |
Maximum allowable body-fat % (age / sex)
| Age group | Men (max %) | Women (max %) |
|---|---|---|
| All ages | 26% | 36% |
Fill in your own measurements — the worksheet prints with the official thresholds above.
