My sister is competing level 9 and has all level 10 skills but she is very weak on vault. She has had 2 meets this season already, got 9.05 (she felt she had done her best on that one) and 8.4 on the other (didnt land that vault). Its not just about the scores; her coach says her vault is the only thing holding her back - she could have competed level 10 this year on all other events. She does a Yurchenko piked but doesnt have enough explosive power and usually has trouble landing it (over-rotates it). She has starting training a Yurchenko layout and finds it easier but not competition ready with it yet. Anyone have any simple suggestions she can work on to improve her level 9 vault?
