Flying change mayhem????

I was STRUGGLING with getting the right bend and getting a calm, cool and collected change with my horse until I started this exercise. On the long side, do a shallow loop serpentine. When you get to the quarter line, change the bend THEN ask for the change. When you go back to the wall, same thing- change the bend and ask for the change. This helped me set him up and also helped take tension out of the ask. Let me know how this works for you, or if you have any great change exercises!
