DD (8 years old, level 3) complains that her coach presses her and some but not all of her teammates down into middle splits each practice and that it really hurts. Is this normal? I asked why only some of the girls are pushed down and DD said they are the ones who have trouble getting their hips pointed it the right way. DD is very flexible so I'm wondering why she would need help with this and other not and also if this could be harmful in any way.
