Women re-learning a Straddle Cast Handstand

[munchkin3]

DD is re- learning it at her new gym. I find she is really having a tough time breaking the habit of arching her way up. She can do a beautiful correct looking one, (for my eyes) as long as the coach is standing there reminding her to hollow, and almost touch her toes to the bar before snapping shut.
I hope this can be fixed without lasting effects......she has such pretty bars....
