Estimate your body fat percentage using the proven US Navy method. Get insights into your body composition and fitness level.
Body fat percentage provides a more accurate picture of your health and fitness than weight or BMI alone. Unlike these basic measurements, body fat percentage reveals your body composition – the ratio of fat to lean muscle mass.
The US Navy method uses circumference measurements to estimate body fat percentage. While not as precise as DEXA scans or hydrostatic weighing, it's remarkably accurate for a simple measurement-based method, with an error rate of approximately ±3-4%.
The US Navy method is quite accurate with an error rate of ±3-4%. While not as precise as DEXA scans, it's one of the most reliable measurement-based methods available and correlates well with more expensive testing methods.
Women typically store more fat in their hips and thighs due to hormonal differences. The hip measurement helps account for this gender-specific fat distribution pattern, making the calculation more accurate for females.
Healthy ranges vary by gender and fitness level. For men, 10-18% is generally considered healthy, while for women, 16-25% is typical. Athletes often have lower percentages, while some body fat is essential for hormone production and organ protection.
Yes! 💪 Body fat percentage is excellent for tracking fitness progress because it shows changes in body composition, not just weight. You might maintain the same weight while losing fat and gaining muscle.
For tracking progress, measure monthly or bi-weekly. Daily fluctuations are normal due to hydration, food intake, and other factors. Consistent measurement conditions (same time of day, similar hydration) improve accuracy.
