Thank you SO much for this. Can I ask you what you mean by "if she comes above I supple"?
Here is Jane Savoie's explanation:
"Once a horse has developed a steady rhythm (the first ingredient in the training scale), the next goal in training is suppleness. Suppleness refers to your horse’s ability to smoothly change his balance forward and back and side to side. Your horse should be supple in two ways–laterally supple through his side and longitudinally supple over his topline.
Your horse’s muscles need to be loose and elastic through the poll, neck, shoulders, back and hips to accomplish this. As your horse’s physical therapist, use the following exercises to loosen or “unlock” your horse:
POLL: The “poll” refers to the occipital protrusion at the back of the skull. However, in common usage, many people refer to the poll joint, between the atlas (C1) and skull as the poll. The poll is important to you because if your horse is blocked there, your aids can’t go “through” his body. If your horse is supple at the poll, you can position his head at the end of his neck either to the left or to the right from a little turn of the wrist (indirect rein action). Don’t open or close your fingers to supple the poll. If you wiggle the bit or open and close your fingers, you’re just asking your horse to flex at his jaw—not his poll. When your horse is supple at the poll, you’ll feel less resistance when turning your wrist.
NECK: While riding on a circle, use the inside rein in the same way you did when unlocking the poll, except ask for a bigger bend (7 inches to the inside, as opposed to 1 inch when flexing the poll). Do three bends in a row to the inside, quickly but smoothly. Don’t hold the bend and wait for your horse to “give” (that’s his jaw giving, not his neck). Also, keep the contact with his mouth instead of letting the rein get loopy. Be sure to squeeze with your inside leg at the same time you use your inside rein. Keep your outside rein steady and supporting. Don’t let your outside hand go forward. Your hands should stay side-by-side. That outside rein limits the bend to 7 inches. Then you’ll use it to straighten the neck.
After the three “supples”, leave your horse alone for six to eight strides and just maintain an elastic contact with his mouth. Then do another set of three supples. If the suppling was effective, your horse will lengthen and lower his head and neck and feel more relaxed. Repeat this neck suppling exercise in the other direction. Very stiff horses will require support from the outside leg to prevent their hindquarters from swinging off the track of the circle.
SHOULDERS: Starting at the walk, make a 20-meter square instead of a circle. Ride your horse with counter-flexion (His face is positioned 1 inch to the outside.) throughout the exercise. At each corner, move both hands to the inside to swivel your horse’s shoulders around the 90-degree turn. Soften when you complete the turn, but don’t let the reins go loopy. As your horse becomes more supple in his shoulders, you’ll feel less and less resistance in your hands as you slide his shoulders around the corners.
HIPS: Leg yielding loosens and supples your horse’s shoulders, back, and hips. If you’re leg yielding to the right, keep your right leg on the girth to maintain forward movement, and place your left leg three to four inches behind the girth to ask for sideways movement. You can squeeze and release with this leg if your horse isn’t moving sideways enough.
Your left rein asks for flexion by “turning the key in the lock” with your left hand. Keep your right rein steady, supporting contact.
Put weight on the seatbone that’s in the direction you want your horse to move—in this case the right seatbone. But take extra care to remain sitting squarely on your horse. Don’t lean to the right.
Once your horse moves in a regular rhythm and is supple, you’ll be ready to move on to the third ingredient in the training scale—Connection."
