formula for body fat %

[The One]

Hey Everyone, I need someone that knows his body fat to test the accuracy of the formula. It should only be of by a few tenths of a point. I got out of a magazine.

Thank You



Hydrostatic weighing for body fat%


Multiply your weight (in the nude) by 1.082
Example: if you weigh 200,
(200) X (1.082) =216.40


Add 94.42
Example: 216.40 + 94.42 = 310.82
*** (Weight factor) ***


Your waist measurement (at navel) X 4.150
Example: if your waist is 34”
(34) X (4.15) = 141.1
*** (Waist factor)***


Weight Factor – Waist Factor
Example 310.82 – 141.1 = 169.72
(169.72 is your lean body mass)


Your Actual weight – Lean Body Mass
Example: 200 – 169.72 = 30.28
(30.28 is your body fat)

(Body Fat/ Actual Weight) X (100)

Example: (30.28/ 200) X (100) = 15.14%


Your Body Fat would be 15.14%

The only tests I'd recommend are hydrostatic ones @ major Universities every few MONTHS.

All the other tape, hand-held gadget crap things, only serve to provide MAJOR head games and give readings that are all over the place.

My motto is, "If you still have to take bodyfat readings, you're still fat".

I tell my clients to put down the calipers, and get on the treadmill.

[bluethunder]

How does it take in consideration fat stores in all other places not just the waist line?

well im still fat so ummm lol how would you find out if your school has one i go to UMASS amherst its a big school like 30k students. think they would have one?

[The One]

Thanks guys I knew it was no way in hell I was at 25% body fat

[unclemoney]

it said I was 11% bf but im really 9%......

[fballhoss51]

said im 22, but im 12...lol

[big swoll]

i know im not ripped, but i also know that im not 18%bf

[Ultimate]

it says I'm 18% when I know I'm around 11%ish I have that book too it's the NO2 book the 21 day transformation... completely useless...

[The One]

YUP! ultimate, if they have someone use a formula that is so off, Can you imagine how worthless the product(NO2) is?

[lilchef14]

It said i have 20 when I have 13%, got me worried for a sec

UMass should have one. If your in that area, The Harvard Fatiuge Lab has one. But... Hydrostatic will only be correct if the subject can release all of their residual air volume... underwater. 99% cannot do it... nobody likes being underwater, out of breath. If you can find someone who know how to use calipers (Lange ONLY) ... you can get within 2-3%...

[Sustman]

It said that I was around 11.76% which I think is pretty accurate right now. Maybe I'm a little bit less but I thought this test worked alright!

[hikneeken]

forget all those calculating methods, i like to just follow this rule,8%all abs show when flexed,6%all abs show unflex,4%dry looking with all abs shown unflexed... i personally stay around 7-9
