Nikki we really haven't been following a formal RC method tbh. We initially started with jump bumps for striding help and some boxwork (on the A-frame only), used hoops several times, and now we're maintaining with random surprise treats hidden at the end of the board. I unfortunately don't have contact obstacles at home so all of our practice is restricted to class or lessons. I'm very lucky that her natural striding seems to support RCs well.
This past trial the RCs really seemed to click and she was speeding up and even crouching as she hit them (not creeping, just getting very low and she's not a BC lol), even with some lateral distance from me.
