I asked my gym manager if there was some way he could measure my bf. He pulled out this handheld machine, entered my height, weight, and age. It had what looked like to be pulse sensors on a cardio machine. He pushed start and it went through it's deal and popped a number on the screen. Now it gave me 11.6% as the readout. I don't remember who made the machine, but if anyone's used one like this before, how accurate is this measurement? I usually get it done when I visit my mom's office (she's a pediatrician) and she's got the calipers and stuff that she borrows from the physical trainer who works next door. I don't think I'm 11%, but if I am"A Native American elder once described his own inner struggles in this manner: Inside of me there are two dogs. One of the dogs is mean and evil.

Sounds like a bioimpedance meter. I had my bodyfat tested with one of these before and the result was very close to what I got from a skinfold caliper testing.

That's exactly it. He said it was pretty close- just didn't know for sure. Thanks Mab!

yep... you can get a measurement done, go take a piss, get measured again and get a completely different number. it tends to underestimate fat in men and overestimate in women. on average, the margin of error is ~4-5%.Originally Posted by jonny21
there is error with skinfold calipers too; but, if done by a skilled technician, it would likely have half the error of bioelectrical impedance.

I got measured with one of those a week before a competition.....it said that I was 21%.....I don't trust those POS's at all. Then, I did it again and changed the age to 20....it said that I was 8%.....if you really want to know....get dunked.

You probably would do better next comp if you could come in a little tighter like maybe 16%Originally Posted by SJA
I was tested on a Tanita and I was 32%. And to answer the question I was NOT 32%BF
