but it depends on the coach too!
because i have a cousin shes 11 years old,and she quickly learned splits,fronthandspring,backhandsprings,both splits(i taught her).
She can do also a fronhandspring with one hand,whick i havent seen a gymnast do that on the beam or floor...
on the tramp she can do back and front tucks and stufff,and my conclusion is that maybe youre right,its not that late to do gym...
Daiane Dos Santos is a pretty example,thanks for posting about her,i didnt knew that! Thankx!
