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
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.
