Well BatDragOn ... perhaps you'll need to change your handle to BatDragOff.
Congratulations on the improvement.
Not that this is the finished product mind you ... but I'd like you to share what she was working on to make these changes and what you feel may have helped the most.
Thank you FFS. I appreciate your help/insight. It's not over yet. I need to get that swing when a pitch is thrown. She took about 100 cuts last night on the bag and they all looked like the one in the video. Next I am going to have her hitting a ball off of a tee and get a video of it. After she gets comfortable with that soft toss & then long toss.
In regards to what I had her change:
Mentally, I had her focus on the queue's "turn the barrel to contact with hands" as you mentioned, and to "keep her back elbow behind her hands".
Physically, I made sure at toe touch her elbow was moving back and up. This back/upward movement peaks at toe touch. This seemed to lock/connect her hands momentarily with her shoulders and prevented her hands from dropping prematurely. When the elbow is going up, the hands can't go down until the back elbow is below the hands.
Thanks for your help. I am sure I will have more questions in the next phase (tee/soft toss).
