Here's where my "dorkiness" showed up. In this case, dorkiness equals big hole in my skill set. I probably should back up a bit and offer more of an explanation.
You see, I never really learned to post. I mean, I could post. Who can't? But it wasn't posting right. I was posting from my knees with my feet behind me, and I was very top heavy. I rode like a Weeble Wobble. You remember that egg shaped toy? That was me. Since endurance riders don't do a lot of posting, it was no big deal. Dressage riders need to post, so I started working on it.
Over the last year I have worked really hard to learn how to post correctly by allowing the horse to lift me while my legs hang relaxed without being grippy. I've also learned to sit back and bend my elbows which keeps my heavier horse from jerking me forward. I've become a fairly decent "poster." I can't yet always tell by feel which diagonal I am on without peeking, but I am getting much better. I feel the diagonals on a circle, but on the straight I still have to look. Nothing like telling the world about your weaknesses.
The way I practiced posting more correctly was to chant, one - two - one - two. If I needed Speedy G to slow down, I posted like this: ooone - twooo, ooone - twooo. It has taken some effort on my part, but I can now slow, or speed up, my horse's rhythm through the post. My weight is much lower, I don't grip with my knees, and my pelvis stays in an open position. This is all great, but I can't do it without the occasional counting and conscious focus, especially when one of the horses is being naughty. When they're relaxed and working well, posting is effortless.
Which brings us back to JL's One, Two, Let, Go lesson. The point of this lesson, which I'll describe in a minute, is to teach the horse not to be heavy by showing him that you won't hold onto him. It teaches him to hold himself up and not depend on the rider to lug his weight around. This may be a hunter/jumper lesson, but since it works so well, I don't care who it was designed for.
Since our earlier work has effectively taught Sydney to be light in the bridle and stretchy at the walk, we started the new exercise at the trot. JL had me pick up the trot. Sydney tipped his weight forward and tried to run the circle. He doesn't yet know that he's supposed to be submissive. JL had me pull back with both reins for a one, two count. Then I was to let go for the same two count. And repeat. The trick to this exercise is knowing how much weight to put in the pull back. She described it in terms of a number. If he's heavy, I pull back with a five or six. If he's getting lighter, I pull back with a two. The number describes the firmness of the pull.
That sounds great. The problem is that I could not coordinate the one, two count with my internal posting count. I tried. Over and over. I just couldn't pat my head and rub my tummy at the same time. JL's comment was that we had finally found a true hole in my training. It is obvious that I need to work on being able to move all of the parts of my body independently of each other. Since I can't yet do that, I finally just sat the trot. Well, sort of. I was dismayed that I was sitting the trot much like when I first started to develop my dressage seat. I hunched forward, gripped with my knees, and brought my heels up. But then ... slowly ... I felt myself relax my lower leg and I was really sitting the trot. It wasn't pretty, but it was working.
From a non-posting seat, I was able to follow JL's count: one ... two ... let ... go. It took some time and a lot of concentration on my part, but I was eventually able to pull with 2s and 3s instead of 6s and 7s. And finally, we established a submissive rhythm. I returned to a posting trot and with JL's encouragement, I began to fiddle. A push here, a nudge there, a rock to the inside, a half-halt with the outside. And at the very last, Sydney gave me some lovely reaching, stretchy trot. AHA!
When we finished the lesson, JL's homework assignments were:
#1. Practice using my body's parts independently of one another, and
#2. Work on the One, Two, Let, Go exercise.
The mind is willing, but in this case, the body is weak!
