Gabrielle,
I just wrote a reply which disappeared! Hate that.
Thanks for your advice. I went yesterday and used the advice of keeping the feet slightly apart (ie not touching) made me realise how wobbly my feet are. I was able to hold the standing position on the second set - on the first I was too wobbly and unbalanced - slowly but surely I will get there. Tomorrow I will work on flexing my foot (I take it that this is to point the toes towards the body).
Step by step I will get there!
I will also use you advice on the Bow pose - basically hold the arms up and just learn to kick.
Thanks so much for that!
As for trying to relax - between focusing on knees locked, tummy in, trying to take in air when have bad sinuses and can hardly breathe and trying to balance it is hard to relax - that will be the day I know I have nailed it!!
Thanks for the advice
