Army Body Fat For Men
For men, the Army-style body fat estimate uses height, neck, and waist measurements. The waist measurement is important because it reflects abdominal size, while neck measurement helps adjust the estimate.
Army Body Fat For Women
For women, the formula uses height, neck, waist, and hip measurements. Hip measurement is included because fat distribution patterns can differ between men and women.

- Keep the tape level and snug, but not too tight.
- Measure waist after a normal exhale.
- Measure neck below the larynx area.
- For women, measure hips at the widest point.
