Yep, that’s what happened to my wife… she started rhythmic gymnastic and ballet at 4 in Eastern Europe in the 90s with a brutal coach, had to stop at 12 for an injury, and she has been having chronic pain and arthritis since she was 17. Anything taken to the extreme can have lifelong consequences.

Reminder that coach is not your friend, the incentives are wrong. If they burn through 100 kids damaging them for life, and one survives to win an Olympic medal, that’s what counts as success.
