    What do you know about bodyfat tests?

    After 4 months of pretty hardcore dieting, I lost 78 and decided to get my BF % tested at my gym. I also have a Tanita body fat scale at home that uses Bioelectrical Impedance Analysis to measure BF (or so they say!). I am 5'10" and started at 255lbs and ended at 177lbs. According to my scale at home I went from 41%BF to 19%BF... however when I got tested at my gym the computer gave me a reading of 9%. My gym uses a system from RJL Systems... this is supposed to be extremely accurate (or so they say!).

    There is a pretty big swing between 9% and 18%... which one is accurate???

    WOW what a tranformation I'm so happy for you and I'm sure you are

    there is no way you are at 19 in the after pic

    you have a great deal of lean mass and your abs are very clear

    I would go with the 9%

    I honestly have been convinced lately that calipers are the most accurate

    PS: what was your strategy to lose all this weight ?

    I know someone will ask

    (very inspiring by the way)

    The MOST accurate test is the water test were you are dunked in a tank. It is difficult to find a place to do it and expensive. Calipers are effective, but it depends on how and where your body stores fat. The scales that measure impedence are often inaccurate because the amount of water in your system affects the reading. looking at the pictures, I would go with the reading of 9%.
    I may not always be right, but I'm never wrong

    as long as your consistant with your tests thats all that matter.
    if your using your scale thing, you know when your improving or not, with calipers assuming you pinch in the same areas you know if your getting better or not...

    Isn't that all that really matters?

    Its tough to eyeball... If I were to guess I'd say your between 9-12%
