We've had the same thing with squat on and various other skills. The privates have always helped, bc she and the coach were able to stage the skill in a way that made her feel safe and not pressured. Like for giants, first it was fully spotted. Then CHS, he'd hold, and then let her do the giant, and he'd help her stop. Then he'd stand there while she did it herself and just be ready to catch her, then he stood at the top of the pit bar ladder, at the bottom, and finally just watch from a distance. Coaches can't do that while training 7 other girls so I really think it's worth it. Plus in a private I find they tend to be more understanding and less just "move it forward."
