Now I'm taking for granted that Ezra and her mare are happily walking around in their 10 to 12 foot circles. The mare will drop her head and relax into Ezra's legs.
Now I would start walking this mare in a series of lines the length of the arena. We're back to the "check out the horse and rider at the same time exercises".
Look straight ahead, make sure you're balanced evenly on your seat bones, and your shoulders are even. Your riding two-handed, your hands are relaxed, soft and maintain very light contact with your mare. My definition of contact is when you can just feel the horses mouth at the end of your reins. Your mare has an equal amount of space on both sides of her neck between her and the reins.
Your legs are relaxed and neutral. The mid-point of my calves lightly touch the sides of my horse when I'm relaxed.
Don't be in a hurry to here. Instead, experiment a little. Drop your weight onto your left seat bone. Simply wait and see what happens, keep looking straight ahead.
What I'm thinking will happen is she will attempt to reposition herself evenly under you. Her shoulder will come to the left and realign her. Immediately rebalance your weight evenly on your seat bones.
Play with this a little. Keep looking straight ahead and drop your right seat bone. She should drift, shoulder first to the right in an attempt to get under you again. Make sure you rebalance as soon as she steps over so she will understand that's what you want.
Wander up and down the arena, (off the rail) dropping the left seat bone, then the right.
Think about how she moves, were your legs fall, how your shoulders shift. Make sure you're not leaning right or left, just dropping about five pounds of weight into that seat bone to get her to move left and right.
Keep your hands out of this. The challenge is to get her to move without your hands turning her.
OK! Enough of that.
Now we're going to start to push your mare into a turn.
Walk about ten feet off the rail. As you reach a corner you will stop. Rock back on your pockets. (preferably Wranglers) Your outside (wall-side) leg will come off your mare. Your inside leg will slide back 6-10 inches and you will push with your calf.
Your mare should move her hindquarters towards the wall and into your opening leg in a turn on the forehand..
You will probably have to steady her with your hands on the reins to stop her forward motion.
Do a quarter turn and walk to the next wall.
I'm on drugs today BTW, so I'm not sure I'm making any sense.
Essentially I want you to walk down each wall, stop, do 1/4 turn on the forehand with the haunches moving toward the wall and then continue on.
Both directions please. Think about getting your desired response with your legs first, only using her reins to help balance her. Her head should stay fairly straight.
If your mare needs to bend her neck and nose to do a turn on the forehand then practice until she can move her haunches and keep her head and neck straight.
Once again, think about what's happening here.
In the first exercise she is moving into your dropped weight.
In the next she is moving away from your dropped weight.
The last exercise for the day is to walk random straight lines around the arena. Stop, do a 360 turn on the forehand and move off in the next direction.Turn left and right until she will softly turn for you without a lot of fuss.
Think about your balance. Be conscious of your weight at all times. Have fun, really!
