Some tips from me too.
For me there is a huge difference between yielding and shoulder in concerning the leg aids.
With shoulder in, you ask the horse to bend around your inside leg and for the horse to be able to do that, it’s essential that you keep your inside leg long.
It is then really hard to ask the shoulders to come of the track without the help of the outside rein.
What I do with the cordeo is, I lift and take it to the inside for the bend as if going onto a circle and then lift him straight again, with my upper body in the direction of the track and I sort of continue these two sets of aids which have worked on most horses who are ready to offer shoulder in of course, and it has worked for my students.
Just like with the inside rein we riders often tend to grab hold of it, the same happens with the cordeo, we try to create bend, or at least I did ha ha ! Of course then the horse wants to move off the track and the inside leg will come back to keep him there, but that is not shoulder in but some sort of rigid renvers ha ha !
To prepare shoulder in, first work on proper bend with your inside leg only on the circle, then on the track and then ask for shoulder for with the slight help of the cordeo.
For reacting to the leg yield; indeed as Sue says, in the same place will make it click.
Also, I ask the horse to move towards the fence and then ask a halt. Then I place one leg back a little and ask. To avoid to adding pressure and starting to push like crazy, take your leg off again and again and ask softly every time. When the horse indeed, just yields a tiny bit, reward like crazy.
With every lateral movement it is essential to;
- use your leg when the belly/barrel swings away from your leg (the moment the inside hind leg comes forward)
- release your leg after a few seconds and repeat only if needed.
The video Karen’s placed before by J.P. are so excellent!
Anyway, more and more I see how important it is to release your aids each pace and repeat as needed.
It’s not my invention alas, it is called by master La Gueriniere ‘le descent de main et des jambes’
Which simply means, let your hands and legs ‘hang’ doing nothing anymore.
Works like a charm.
