 It's like in the saddle, sitting taller to move forward, relaxing my posture, and seeing if she'll settle down and relax her posture as well. Very well. Find a halt, a little tension, there, a little relaxation, very nice. So now, when I reach up with a whip, I'll simulate the same thing that I did with the brush. The whip would represent our leg if we were on her back. It's a driving aid. Notice my posture is tall. Thinking about my chest, and where am I pointing my chest? Where am I directing my attention? If I direct it more back behind her and move my feet, it would make a lot of sense for her to move her hind quarters. If I direct my chest more forward and open, it might make sense for her to move forward.
