Same as you Mrs R.
I started going to the gym just over a year ago, lost almost 2 stone by November but apart from a few pounds thats been it since. The wierd one was in Jan though when I'd lost a couple of pounds, got tested at the gym and my fat % had gone up, the next assessment I was 2 pounds up but fat % had dropped below level prior to Jan!
It is disheartening though.
Then again - just had a week in London on a course, tried to eat healthy but had a little bit where I seccumbed, and having nothing to do it meant the pub every evening....but I did manage 3 sessions in the hotel gym. Got home and put just 2lb on....but seeing as i'm doing the fit club at work I need to get right back on track (he says with a pint of beer at the side of him!)
