Lydia said that the way to do it was to start with shoulders back, chest out and bum back. I can get that bit. What then follows can probably be best described as "having a fit", which is then followed by giggling... Apparently I should be sitting on an invisble chair instead...
Is it better to try and exaggerate the movement (ie make it bigger)? I think I'm trying not to, which is why it ends up as looking like a fit...
Also, once I've sat down on my invisible chair - what then? just pop back up again?
I figure I've got a flexible body so I should be able to do this...
Anyone got any handy hints???
Cheers!
