Mary Wanless teaches leg yield without forcing it. The key: keep your body facing where you're going and weight over the horse. Common mistakes are pulling the rein, which makes the horse bend like a C, or shifting your ribs and seat off balance so you end up behind instead of over the horse.
So if I were to come down the center line and decide I was going to leg yield over to K, my horse would like to go, well, let's just walk to K. And I'd have to go, no, I'm twizzling you. So we're going to walk to K this way. And he'd go, no, that would be so much easier. And I'd go, no, I want to twizzle you. Keep your body facing in this direction. Even though both of our bodies are going to transmit force to have you move this way on a circle. What happens to most people when they lose it in this kind of scenario of pulling on this rein, giving this one, the horse's nose comes to the inside, but his, he jackknifes through his wither and falls out through there. When you look at that from the back, you see this, a C curve. What happens to people when they go laterally, though, is not that. And the typical pattern would be the rider wants to leg yield this way and has to make this force transmission from here in her body and the horse's body to that way. And she easily starts going, right, horse, we're going that way. Are you ready? And she gets very shovey and pushy with this side of her body. This seat bone tends to fall off. And the shape she makes with her body not of a C curve so much, but of what I think of as break dance. So if she starts doing this and trying to push the horse this way, she will tend to move her ribs over there. If I sit on somebody's back piggyback and I move my body here, the person carrying me is not going to want to go over there. Self preservation will have them stay under me. So when you go to your horse, right horse, we're going this way. He's not very likely to step that way. He needs your weight more here so that you're over him in the direction you're wanting him to go and not, as it were, left behind, trying to get it to happen from here. Sam.
