At dd's gym, level 3 practices 9 hours, level 2--6 hours, level 1--4 hours. These levels combined have only lost 1 meet in 3 years, so I really think it's the coaching/work ethic/ practice agenda that makes a difference, not piling on more hours or restricting hours. I've been around this sport for most of my adult life, and I have watched phenomenal compulsories burn out from over-zealous parents piling on the private lessons and outside the gym practice. I have also seen mediocre compulsories who blossom at the optional level because they stuck with it and eventually it clicked. I have watched 2 girls go on to Div 1 full scholarships without ever taking a private lesson or attending many summer camps. I have also seen the ones who skip a few levels or score out quickly who do great and make it all the way through to level 10+. It really does depend on the kid, the training, and the good fortune of not getting injured. 30 hours will not help any aged child who does not have the mental fortitude or physical ability, while 9 hours can be enough for a child to be the absolute best gymnast in the state.
So don't fret too much. And remember that this sport is a marathon, not a sprint. Any given practice or meet can be their last practice or meet, so enjoy it. Admire their skill and be amazed at your brilliant gymnast, and try not to worry too much about what's next or if they're training enough/not enough. Believe me, simply climbing up on that beam and walking on is an accomplishment. [emoji23][emoji4]
