Suzanne, thanks so much for the support!
I have a list of things to do, my PT did a session of it the other week so I knew how to do everything and I will have my music on, though maybe I need something other than my standard running playlist!
In terms of the strength and running, I had been happily running for two years and thought that my legs were in ok shape, until I started with the PT. The combination of body weight training such as squats and lunges and burpees (and every other kind of exercise under the sun including suspension) and and then weight bearing, with kettle bells and weights which I have got progressively heavier with has made a huge difference.
I can run up hills stronger, run longer distances before I fatigue and in general feel stronger. Obviously it has also helped aerobically as I have been doing some hiit stuff in sessions and I feel that my tolerance for aerobic exercise has also increased.
And I have lost inches though not much weight so I suppose my muscle tone has massively developed.
Thankfully tomorrow I am going to another gym in the local authority's chain so I will hopefully see no- one I know and can look like an idiot without anyone laughing at me!
What is odd is that I was a member of a gym from the age of 21 to 33 and no one ever showed me what to do with a weight or a kettle bell. I thought that going to the gym meant running and cross training and cycling and then using a resistance machine for my inner thighs, then going home! I literally did the same programme I was showed when I turned up young and naive to my university gym, and I never thought to do anything else 
So in order to not feel like I have wasted the last 17 hours with the PT I need to get this right. I'm just a bit scared! Daft really!
