I found I was a lot better 2nd and 3rd time round.. First time round I had no idea what to expect but I did the next time so knew what my body needed me to do

It still hurt mind you but as I knew that standing the first time was really going to hurt I held my stomach took a deep breath and got on with it.. (I had a panic attack the first time) plus you know you need to move and to hold your back straight..
