Me? Excited? Oh yes, I have no doubt that the majority of the time it is my fault. And the other minority of the time it's my fault because I didn't train it right to begin with
It does usually appear to be a case of timing. Either I decelerated too late, or showed too much motion. But there are occasions where she gets in this "WHEEEEEEE" mentality and doesn't pay attention.
This video is really the best I have. It's possible that I showed too much forward motion, but I do decelerate and come to a stop and she slices the jump and goes really wide to the weaves (start at 1 minute). After this video I brought her back and just stood next to the jump before the weaves and tried to get her to jump it in collection and she just would not do it.

I'd love to see any exercises you have!
