I don't really know more about the boys than I have already put, we seem to have quite a lot training for elite level1 this year (compared to the size of the boys squad) and I only know what the parents have told me in the waiting area. They train well over 20 hours per week though and some of the things I have seen them training are Giants, round off flic tuck back, round off flic layout, handstands on rings, they seem more advanced than our girls training to do level 4 next year although I guess age wise they would be the same as this years 4s and we don't have any of them to directly compare.
I must admit when I was told they didn't compete until the year they turn 9 I assumed they actually didn't compete at all like the girls but they seem to compete just not the national level system.
