About the U.S. Navy Method
The U.S. Navy body fat formula uses measurements of your neck, waist (and hips for women) along with height to estimate body fat percentage.
While not as accurate as methods like DEXA scans or hydrostatic weighing, it provides a reasonable estimate using only a tape measure.
How to Measure
Measure at the navel level while standing relaxed. Don't suck in your stomach.
Measure just below the larynx (Adam's apple), with the tape slightly sloping down at the front.
Measure at the widest point of your hips/buttocks.
Tip: Measure first thing in the morning for consistency.
