Oh, I feel for that flyer! This is definitely largely a flyer trick... flyer's to do, flyer's to fuck up. I'm so lucky that the Ant is patient with me (and knows he requires patience from me, too) and works with me, and mostly lets Pokemon do the coaching.

Front mount is physically easier than jumping onto canes, by far. I think.

I don't know if this would help her, but what helped us a lot is to alternate one tempo and one real try, one tempo and one real try. In the tempos I just lift my butt as high as I can (pulling from the middle of my rounded back) and push my hands down to my feet or thereabouts, piking, then come back down.
