I have to agree and say that training 34 hours a week is a HUGE factor contributing to injuries. Not sure what your options are if that’s the norm near you though. Unless she’s training for the Olympics, that seems excessive.
Our girls all dropped hours about a year or so ago after injuries went up a bit in the gym. our upper level (8-10) girls mostly have dropped back to 20 hours now, and are better than ever. The only girls doing 25 are our homeschool group of 8-10s. 1.5 years ago we had several training groups doing 30 hours over the summer, and thankfully our head coach realized it wasn’t helpful.
