Thanks for all your comments. We are training the reinback pretty much as most of you have suggested - a good halt, slight lightening of the seat, using our legs slightly behind the girth to ask for activity behind, but into a “non-allowing” hand. And then moving our legs forward and “allowing” with the hand to signal the horse to step forward again. Both trainer and I ride him, and we use the same aids. As I said, he has gotten fairly good at the initial reinback at home, but the double reinback at 4-3 sort of befuddles him. He seems to think he is being punished - he has a very strong sense of self (he can be a bit stallion-y at times), and he just doesn’t understand why he has to back up twice in a row. It’s just a little too much “submission” for His Nibs - LOL![/QUOTE]
If he “gets it” at home, then you’re on the right path. Now, just do more. Do you regularly rein back more than 3-5 steps? If not, do so. Take a dozen steps back. Expect him to continue to back as long as your seat it lightened (or just your pelvis tipped if he’s nice and sensitive to your aids), and expect him to immediately move forwards when you change your seat to normal sitting. Do it often and without worrying that you’re going to upset him or wreck him or something. You won’t.
For straightness, get off the wall. Work on TOF and TOH step by tiny little step in the middle of the arena. IOW, ask for not even a quarter of a half pirouette. Teach him to listen to little aids and wait for more instruction. Then play again with the rein back taking it step by step and correcting as necessary. It will eventually straighten and you will be able to restore the flow.
If straightness is still tough, build a little backing chute out of ground poles or railway ties. Put a right angle(!) in it and practice backing through it without touching the sides. You’ll teach yourself better feel in the rein back for straightness corrections and you’ll teach your horse to listen and step carefully exactly where you ask him to step.
Ok, now if your horse doesn’t truly “get it” at home, get off and go back to in hand work and put a really strong verbal tag on it. You’ll teach it one thoughtful step at a time. “Back” horse takes one step back and gets a reward. Repeat. When you lead forward out of those steps (and it doesn’t have to be after every step) take just a quiet, thoughtful step or two. Don’t wander off. Keep yourself and the horse on task for the duration of the lesson. Boring as all get out, but it works.
Practice your verbal tag anywhere, anytime. I use it a lot while grooming - low stress, easy as pie, and really helps to install the verbal cue.
Good luck, or rather, Good Practice!
