Estimating Bodyfat

It's that time of year again. Before setting my health and fitness goals for 2006, I decided to check the status of a few things first. One of these is my current level of bodyfat - last estimated back in April this year.

Once again I used the same technique as used by the US Department of Defense, the formula being :

% body fat = 86.010 x log10(abdomen - neck) - 70.041 x log10(height) + 36.76

Note that the formula is a little different for females :

% body fat = 163.205 x log10(waist + hip - neck) - 97.684 x log10(height) - 78.387

Brilliant device. If your shoulders aren't quite as flexible as you'd like, grab The Rotater. Love it.
And if you've already got one - or are looking for another type of device - swing by the Straight to the Bar Store. It's all in there.

Plugging in measurements for abdomen, neck and height gave me :

%bf = 86.010 x log10 (35-16)-70.041 x log10(72) + 36.76 = 16.65617 (slightly better than last time).

For demonstration videos showing how the measurements should be taken, have a look at the Physical Readiness section of the NPC site.
