This idea has change a lot about my riding, not perminantly (yet), but my approach has changed. I was having a heck of a time with left shoulder in, so I let go of the left rein and, go figure, there it was. Canter work, particularly left, has been hard because she does not enjoy feeling out of balance. I let go of trying to force her into balance and started playing with exercises the force her to balance herself on her own terms, such as shallow serpentines.
I took that information and applied it to something my dressage trainer, Deb, told me: hold the right contact going left. I thought to myself, do I even have right contact? Or is what I'm holding just pressure with nothing behind it. So, again, I left go of what I thought Was contact and asked her to come into it with a lot of exercises and a lot of encouraging outside leg.
Let go.
Set her up for making the decision herself.
Try not to be a control freak.
These are the driving ideas behind what I am trying to do with my mare. I took a concept and ran with it.
And I'm sure it will run me into some trouble, it already has. Suki does not always make decision I agree with. For example, she turned 10 feet too early onto a "trail" at a dead gallop in the woods while I was trying to retrieve a stirrup. But, I survived and she did not put a foot wrong.
Somehow, I doubt that's what Denny intended for me to do by letting her be the free spirit she is, but I can tell you he commented on how much more comfortable I seemed on her during my next lesson.
I suppose any time you go through thick forest on a horse, burying your face in the neck to avoid being cracked by a branch and shoving yourself back on by pushing off the trees she is dodging, your participating in some sort of trust building exercise. It's like submersion therapy for the type a personality type: relax and go with it or have a Wylie-Coyote moment with a tree.
