What this means
The U.S. Navy method estimates body fat from a handful of body circumferences. It's free, repeatable and surprisingly decent — typically within a few percent of a DEXA scan for most people. Body fat percentage tells you far more about your physique than scale weight alone.
Recommendations
- Measure first thing in the morning, relaxed, using a snug (not tight) tape for consistency.
- Track the trend over weeks rather than fixating on a single reading.
Watch out
- This is an estimate. Body composition varies with hydration and measurement technique — expect a margin of ±3%.
