I am LOVING this course. I think you can still join but not for very much longer. I have been practicing like mad and am seeing a difference in all the horses:
Cally is lifting her back more and lengthening her stride, Dylan is moving more freely (Hurrah!!!!) and Oscar is going absolutely beautifully. He came to us very well schooled but I was never that good at keeping him working forward and over his back, but he transformed within 10 minutes of me changing my alignment. Must try and get some video. I don't ride Lisa but maybe I'll have a go on her too.
One thing that I find very interesting is that Mary explained why draw reins, side reins are not helpful: she said if a horse is encouraged to flex at the poll with gadgets, he is likely to concertina his neck in rather than stretch it forward. So although it will have the vertical face and arched neck, the neck will be too close to the riders body. I have seen lots of my friends' horses look exactly like that. And when I first got on Oscar today he was doing that too. Bringing his head down and contracting his neck in, not arching forward and down. But using the homework techniques, his neck stretched forward more and as it did so his stride lengthened and he moved much better.
