So normal. No one from my daughter's training group, level 2 or level 3 teams are still in the sport. We lost a lot around level 4/5, added some and then a lot again around level 8. In fact, I just checked and only 4 out of 12 of my daughter's level 8 team are still in the sport 2 years later. But her team has picked up a lot of girls from other teams so her level 9 and 10 teams were still quite large.We are starting to notice that several gymnasts are quitting gymnastics after level 8. Different reasons though - injuries, skills are just too hard, tired of the level of commitment that gymnastics takes, etc. Are you seeing a similar trend at your gym?
