Hi
For the clear hips:
1- The stap bar is a really good idea, do lots and lots of these. Always spot and shape
2- Explain to her that the wrist shifting happens really late, and she really needs to pull the bar down hard!. I am pretty sure that when she shoots to soon she is throwing her head, and just doesn't hold the hollow position. This is conditioning and orientation. WORK on lots and lots of back extension rolls that are JUST!!! short of handstand, but that maintain the hollow position. So pretty much she rolls just short of the handstands and then rolls back out all the time holding head neutral, and chest in, and butt tight, and in a nice hollow position
3- Spot her through it.. if you are strong enough and if she is tight enough. Have her hang under the bar in a hollow hold, and then grab her shoulders and spot her up to handstand, pretty much like like as if you spotted someone for a stalder. If she is loose it will show.
4- Encourage her to focus on circling not kicking her feet. She needs to really understand how to drive through her back.. Fromw when she hits horizontal postion out of a cast going into the clear hip, her shoulders should be directly over the hands, and from now she needs to aggresively try and turn over under the bar and thus load the bar, which will spring her up.
The clearhip to handstand is a very labour intensive skill, you will need to spot it over and over and over again. In the mean times you just need to work lots and lots of conditioning (specific) regarding open then shoulders while being hollow, lots hanging hollow holds, etc...
The cast could be:
a- She is still lacking the power, and thus splits the legs a little to reduce inertia and thus help her get up there.
b- She is arching in her back excessively, this will from anatomicaly reasons split her legs apart, especially if the knees are straight
c- She is lazy and just doesn't hold tight enough
d- She is unaware of it, even though you tell her she doesn't feel it. Solution
a- Spot her and stop her when she does it and ask her to feel where her legs are and then ask her to put her legs together and then understand the difference
b- VIDEO! haha wonder trick this one.
Do lots of heel drives (some call them hug the twiky), cast machine drills (can be done using a swiss ball), planche lever to handstands (spotted of course) lots and lots
If she is really quite close to doing the cast to handstands with legs together then keep working it, it will come around. Once again conditioning conditioning condutioning.
