Checking B-Fat

[MrBig Senior Member Find all posts View Profile Close MrBig]

I have the caliper Slim Guide made by Creative Health. It comes with an instruction guide that give you a few ways to check your b-fat. The first one is the Durin Womersly data. When using this data there are 4 locations to measure, the back of upper arm, front of upper arm, back below shoulder blade and side of waist. Now when I use this data my b-fat measures 18%.
Now there is another way to check your b-fat and thats the Jackson Pollock data, with this data theres only 3 location to measure with this data. The chest, abdomen and the thigh. When I use this data my b-fat measure 13.5%.
Does anyone have an opinion on these two ways of getting your b-fat????

One thing I should mention is that with the Durin Womersly data, I have my wife do it and with the Jackson Pollock way I can do it myself. I'm thinking she's not doing it right, I don't know???

The % given is an average of the locations that you pinch. Some areas hold more fat that others you can find formulas online that will let you factor in up to like 9 pinch sites I think. Idk, I would just find a few different formulas, and average the results. You'll find that your readings will vary up to 3% lol

Theres one more I just check and that is one location, the back of upper arm. Now from this location it says I'm 14%, I guess theres my average. lol

I have a scale that tells all that. According to it I am a fat bastard. These scales can't be right, can they?

The scales will be off by a different amount for everyone, for me, they have been within a half a percent, but I have friends that they read off by 6-7% lol. A pinch test is more accurate (usually within~3%)
