That is SO wrong! I can see that girl in splints at some stage of her life. Take nice little girls and make their bodis do things that will injure and debilitate them... eventually. Or tear a muscle right when she needs to compete after spending every day since she was 3 working to a goal. Grrrrrrrrrrrrrrrrr. Pretty amazing though. I have never seen a routine like this.
There can be some nasty accidents in gymnastics though....
Just keep swimming... just keep swimming.. just keep swimming....
