confusion!!!

[texas_venom316]

hey guys i went to my local leisure centre 2 weeks ago on this machine that measure ur bmi, and body fat, and the measurements were as follows

13st 11lb body fat 18%

and today i went

13st 1lb body fat 18%

so as you can see my body fat hasnt decreased but my weight has, so im assuming its muscle im burning off which i cant understand because im lifting heavier in the gym ???? any ideas ... how reliable are those machines?

I dont trust those machines at all.

Not very accurate. the calipers are the most accurate and that is if you have the same person measure you each time.
the results of the machine you used can be effected by how much water you drank that day.

I thought that the hydrostatic tank thing is supposed to be the most efficient way of measuring ones bf %?

It is, but it can be difficult finding somewhere to get hydrostatically tested.

No way bro I got one in my room, there like $19.99 at walgreens, I dunk myself all the time!!

Hydrostatic is best, but my Tanita InnerScan BC533, is quite accurate (with the latest indexed equations) and very comprehensive, here are the measurement categories:

i see , but if you go at the same time e.g. in the morning before you eat anything then perhaps its ok for comparitive purposes ?

Very true...readings/measurements at the same times and under similar conditions are always ideal. But the more output data you possess, the better you're able to account for dependant variables. For example, if my weight is up 2lbs, mid-day then my body water measure will likely also be elevated. Plus, I can consider the number of calories consumed thus far, and subtract them from my total maintenance allotment, did I exercise yet, how much cardio was done, etc.
