The face of a woman who just bagged herself a spot on the transform program!!! 
That was without doubt the hardest 30 mins of my life. Friends, I actually vomited. 
So I walked in and my work friend was already there and had already signed me up for Transform 
The PT who still has spaces took me into the office and I had a short interview with her. She asked about my motivation, health, lowest weight and highest ever weight and oddly, why am I fat I answered if I knew that mate I wouldnt be!
Anyway, she was really honest with me and said she's never worked with someone as heavy as me. Heaviest she's trained is 15st start weight so the fact I've come down from 19st 1lb to 16st 0lbs with just diet tells her I've got nutrition nailed she supports an LCHF lifestyle and eats that way herself although has porridge after morning work outs. She went through my my fitness pal account with me and says if it's accurate (which it is) she's happy for me to continue eating as I am.
Her next bit of honesty was brutal and to be honest, I nearly walked out. Basically, she rejected me from the program in the interview because she said she couldn't see how someone as big as me could work out to the level she needs. I got really upset by that but adopted my very best mumsnet death stare and gradually, upset became mightily pissed off. How bloody dare she. 
With no information about me other than my weight, she had decided I wouldn't work hard enough to be trained by her and I was a waste of time!
Anyway, I said I thought that judging me so quickly was unfair and can we still just do the group class and if she still rejects me at least I know I wasn't good enough on my own merit not on her snap judgement. She agreed. All fine.
She is lovely by the way, no hard feelings and I understand her prejudice, she's never been overweight so she doesn't understand it's its own special brand of hard work.
Now, you know it's going to be tough when your trainer follows you into the gym carrying a bucket. 
that should have been my first clue that she'd pissed me off on purpose but I had the red mist of rage at that point and just wanted to get the session done so I could have a cry in my car, come on here and rant at you lot about it
So I entered beast mode and I absolutely gunned for her in the session. She brought out the 'how fucking dare you' adrenaline rush you get when you're angry and I was so pissed off I just went for it. 30 different stations (10 cardio, 20 resistance), each for 1 minute back to back for half an hour. I discovered the purpose of the bucket when she shoved it under my face after station 18 which was rowing and I vomited straight into it.
There were about 5 stations I physically can't do (fat in the way) but I tried everything and after the 30th minute I was actually feeling like I had a bit of a second wind.
So we finished and I got a round of applause from a few of the other trainers and my friend too for actually finishing.
It transpires that I was played like a fiddle .. they tell you no at the interview stage to see if you actually commit to doing the session or whether you use the fact you're told you're not good enough to slack off and not work your hardest.
Because I got angry and wanted to prove her wrong, I now have a spot on her books
I feel incredibly, incredibly proud of myself and for the first time ever I feel like my body did something I loved it for. It didn't break and I didn't pass out. We're going to work on the vomit...
