US Navy Method of Body-fat Estimation for Men
Body-fat % = 86.010 x log10(stomach – neck) – 70.041 x log10(height) + 36.76
- Height – Get someone else to do it for you if possible.
- Stomach – Measure at the navel. Have a relaxed stomach, exhaled but, don’t forcefully push it out!
- Neck – Keep your head straight, look forward. Keep your shoulders down and relaxed.
- Measure three times for each and average the three.
