I was okay with all of his instructions except for the heel thing. No matter how hard I tried to push my heels down, they just popped right back up. Although once he had me ride with no stirrups, my heels did get lower.
When you're following a relatively straight trail for miles (even with some curves), it's easy to work on your position because there is not much steering involved, and the trail keeps your horse's go button activated. So while Speedy marched along, I got a definite feel for a swinging hip and how it feels to ride with a loose leg.
As those two ideas were really taking hold, I realized that I could now sink down through my heels as I was doing a rising trot. In fact, when I got it right, Speedy moved out even better.
It was a very new sensation ... for both of us. When I insisted on some self-carriage by bumping him off my hands (purposefully) and then being vigilant that I didn't hold him up though the belly and shoulders with my legs, his trot had much more swing, loft, and stretch. Ooh la la was that ever fun!
Give us another week or eighty-seven. We'll get it.
