OK, so I have had a personal trainer for a month.
My weight has gone down my a quarter of a stone. Means nothing to me, really.
My body fat is apparently the same, but I don't trust the scales.
My arms and chest have shrunk slightly which is fine, as I'd not been working on them so much.
My thighs and hips are bigger (muscle, not fat!).
My waist has gone down - 34" to 32 3/4".
That last one is the biggie for me. My blood pressure is apparently insanely good, too, and I have the recovery time of Cristiano Ronaldo or something. Just not his height, his looks, his money, his talent...
