Gnc machine

Has anyone tried the machine outside of gnc at chinook?
It measures your height, weight, bmi, body fat, and heat rate.
How accurate is this machine?

Funny thing... when I bought my scale the sales person said weigh yourself after a shower...

So curiousity got the best of me... weigh before, get bf%.... shower, weigh again.. bf% drops 2% from a shower... woohoo get me an infomercial, do I have something to sell the masses...

My scale has hydration on it as well... although I am not sure how accurate it is I know that if I am low the bf% shoots up, and if I have drank a ton, bf% goes down. Assuming that this has something to due with the ease of the current passing through your body :dunno:

I have the hand model as well and it is more accurate than the scale, but still not as good as the calipers (either electronic or mechanical), but still not that far off.

BMI is a ridiculas measurment... even my GP says so, which amazed me.

Best way to find out your BF is go get a pinch test done. Don't know who does em in Calgary, but it's one of the more accurate ways of testing.

As long as the person doing it knows what they are doing it...and preferably not using plastic calipers.....and there are three different versions, 3 point 7 point and 9 or 11 point.. something like that.. it has been a while.. I use a 3 point as it is close enough as I am no athelete.

I would reccomend the University or Talisman Centre.. I know there are credible people there, some gyms might have people that can do it.

you can buy a body fat caliper for like 10 bucks at gnc. Its the plastic one but it works great. The more points you take the more accurate it is.
