My impression is that there are 2 issues. Camelia probably isn’t a good enough coach for this level. For any gymnast (has she ever coached another elite?). But she is particularly unsuited to coaching her own child. From what I have heard, there is no plan, structure or discipline to Sabrina’s training. They turn up and they do what they want. Not because Sabrina is rebelling against her mother, it’s just never been enforced by Camelia. This was the large part of the issue between the Voinea’s and the previous national team coaches, Sabrina and Camelia weren’t willing to put the work in that was expected of everyone else.
