Women Beam back handspring help

[Newbiemom82]

Hi everyone! My daughter is struggling with her back handspring on beam and could use some tips, it’s just not clicking. Her coach says she needs to keep her shoulders open, she seems so focussed on making sure her hands land right that her shoulders close and one of both hands end up turning in, her arms bend etc. How does she keep her shoulders open when one hand has to land in front of the other? She can do a beautiful back handspring on floor, I think she is overthinking it. Any advice? Thanks!
