And how does one , mounted, ask the horse to contract these muscles? I’m having a hard time wraping my mind around the reality of this, but then, I frequently have difficulties with reality, or what people tell me is reality.[/QUOTE]
I’m setting myself up for a possible massacre here, but because I think Alicen is asking honestly, and because there’s a dramatic difference in my horse from one picture to another on the same day… I’m posting these despite the fact I’m clearly out of shape, in too huntery a position, open fingers, don’t have my elbows bent enough, and a host of other riding sins. Also, my horse is showing his tendency to curl I have been working with getting him over as I work on increasingly getting him to accept the bit more and more instead of fearing it.
However… when one discusses “raising the withers” these photos demonstrate it well, I think. My horse was very tense at this show. In this first photo, I have not pushed him into contact. His head is raised, but the base of his neck is lowered, and so is his back. There is a distinct dip behind the saddle and in front of his hips, as he is hollow. You can also actually see the muscles on the underside of his neck are tight and working.

On the other hand, across this diagonal I had pushed him forward with my legs, and he responded by stepping forward into contact. As we achieved contact, despite his ducking slightly behind vertical, the energy my legs were imparting then directed somewhat upward. You can see a triangular muscle being worked right in front of the saddle/his withers, and don’t see the muscles on the underside of his neck working. He’s still using too many muscles to tuck his head and not as relaxed as would be ideal, but he at least demonstrates to you which muscles would be used to lift the withers. His back is also much flatter behind the saddle - because he’s using not just the easy to see muscles in front of his withers, but the ones Ghazzu mentions as well. Keep in mind this is a horse/rider in training level - I’m posting because the angle of the sun gives you a great chance to see the muscles in action, but we demonstrate this nowhere near the ability a higher level horse would/should.

(And if you can’t tell from the above - I disagree that lifting the horse’s head will get it to lift its back, as my horse’s back is clearly lifted much more in the photo with his head LOWER. Lifting a horse’s head can easily make it hollow its back, just as asking a horse to lower its head can. It’s about getting the horse to use its body overall, not just how you locate the head. However, I do agree that if a horse has a locked jaw you can’t really get this. I tend to do leg yields to get my horse to soften - get his body softer, and the head goes where I want without me trying. We also do a lot of figure 8’s, circles, serpentines, other softening maneuvers as mentioned in this therad. At this point, “head where I want” includes the nose not tucking too much, and light but real contact.)
