Japanese and Australian gymnasts also entered the Hawaii events, although it was the Americans who were the ones to beat, taking 1-2 overall in Manning's Level 9 grades.
At the Paradise show, her best placings were bronze medals in the beam and the bar apparatus.
The following week, she won gold in the vault, silver on the floor routine and bronze on the bars.

Another big task for her now she is home will be sending off her impressive results to all her sponsors in a whole heap of "thank you" cards she will write. "It was massive, I raised half of what I needed [to travel] and the sponsors took care of the rest."
Manning has resumed training for gymnastics clinics in April, before the 2016 season starts in winter.
