To be “good” (aiming for National-level competitions) kids need to have been doing 10-hours plus by the age of around seven. Ramping up to over 20 hours by the time she left primary school
There is no evidence that kids need to be doing these hours this early. It’s just what’s always been done.
Yes kids won’t progress as fast so quickly, but ultimately they are less likely to reach their potential as they burn out or injure.
Years ago BG brought in a series of competitions “grades” with set moves designed to slow talented kids- back in the 80’s when 12 year olds were competing in the olympics.
It was supposed to stop coaches pushing too fast and pace them for international competition at 16.
Then over the years the difficulty of the set moves got harder and harder, until now where we’re looking at very young kids doing very hard skills, where they do need to start at 6 on stupid hours to be able to hit that first grade at 8.
The other thing is it’s inextricably linked to age. You pass grade 5 at 8, 4 at 9, 3 at 10, 2 at 11, then two years of “espoir” and two years of junior.
That is effectively the only path to elite gymnastics. There are slower ones, but they aren’t really taken seriously and very few gymnasts qualify that way. Many clubs only pay attention to those kids hitting a grade at the correct year. There’s so many fall off and can’t get back on.
So as it stands it’s all but impossible to start gymnastics at 9, because you can’t pass those grades.
