I don't know where to post this so sorry if its inappropriate. My question is, how accurate are the body fat machine things the trainers make you hold at the gym and does silicone implants effect their accuracy and does swelling from weight training effect them? Thanks anybody

To the best of my knowledge you are not going to put a BF caliper on your breast directly (the 3 point test does not even come close to the breast, the other method seems to come closer to the armpit than the breast), so I cannot see it affecting the result.
And the skin and fat layer are above the muscle, so pulling up the skin and pinching it with the calipers will not be affected by muscle mass. In a more general sense gaining muscle will change your BF composition, but not in a way that would make your calipers inaccurate.()---() York Barbell Club #37 ()---()

I don't think shes is talking about calipers but one of those electrical impedance machines.
I think I recall reading that the implants (assuming silicone and not saline) would be counted as fat since it doesn't conduct electricity but rather impedes it like fat does. Muscle and water both conduct electricity. This is from memory and I don't know how accurate the source was. Hopefully, one of the members that is more versed in electrical engineering will chime in.
On another note, most of those machines are highly inaccurate. I bought one once and got readings that were all over the place in the same day (I found it useless and returned it). I wouldn't put much credence in them.
My understanding is that if you drink a lot of water you can throw them off.Last edited by dumb.bell; 02-24-2012 at 08:03 AM.

This! I had one test done as a "promo" on a very high dollar machine for joining a gym. You held things in your hand and stood on other things... it said 7% BF! Yea yea the problem was my abs were barely showing so try at least double that reading in reality. I find the simple skin fold calipers to be much more accurate as an indication of if your loosing or gaining fat.

those electrical devices are really only useful for trending, and only if you can do it at the same time every day like first thing in the morning, before shower/eating/drinking.
having a glass of water or two can wildly skew the results...so it might be all over the place by the time you're doing this in the gym. also if you're sweating, wet...you'll get different results.
you also get very different results depending on the angle you hold the thing from your body. how hard you squeeze it, if your arms are stright, there's a bunch of fudge factors.
it also won't be an accurate measurement compared with say a body fat caliper...so in short don't put too much stock in what the trainer tells you about body fat in the gym with one of those things.Last edited by Kodokan; 02-24-2012 at 06:56 AM.

I realize you said you weren't going to use one anymore but I thought I would throw my two cents in anyways. The silicone in your implants are incapsulated in a "plastic" type bag that will an insulator to the electrical impedance of the BF calculator. That being the case, your implants should make no difference in the readings from the machine. As already stated these machines aren't the most accurate your better off relying on a mirror or as you said your jeans.

I'm more of a butt man. I can take or leave boobies.

I'm pretty much with you...... although, my attitude is more of a "....once you've seen one pair of boobs, you pretty much want to see them all..."
I mean honestly, even given the chance to look at the most disgusting boobs available, I'm probably gonna at least take a peak. Just sayin'
Again...... butts, boobs, real boobs or fake....... naked women are just the coolest.
Me too....which probably describes my other thoughts in this post. I'm pretty much a 12yo running around in a 41yo body.
My wife is usually embarrassed, but she knew me when I was 16.....so yea, that's her fault.▪█─────█▪ Equipment Crew #4 ▪█─────█▪
