How is the body fat measured? Just on scales? If that is the case I would think it was more fluid loss from the workout than body fat....

My gym has one of those 'things' with handles that meant to send 'waves' through you body to calculate the body fat.
So the trainer puts in my weight, weight, age & sex. I hold it out with my arms in line with my heart and then hold for a few seconds and it calculates the body fat.

The thing that calculates it is based on electrical resistance...something to do with muscles holding more water than fat, when combined with a weight measurement it yields an indication of body fat. I'd say it's more likely that the fluid/electrolyte balance in your body changed while you exercised (and drank water during exercise) and that would be reflected in a different reading.
Your trainer should understand that stuff otherwise it's a pretty meaningless kind of number to give you.

Yes you would think so wouldn't you Marydean?!! But he is a male trainer, so probably doesnt understand the very complicated female body!Especially mine as it seems to be very very strange at times...
So what would be more accurate - the reading before or after my sessions?

Based on what MD said, then I would say beforehand. You may sweat more/less or drink more/less during every workout

I was just about to say it depends on how hydrated you are... yes I'd be more concerned that he didn't know that too.

Aaahhh, so that explains it! I just had another check and we did it after i had already done a session at the gym and it was nothing like the first reading i had done! I decided to just ignore it and concentrate on other measures.
