Certainly not our experience, may be we have been unlucky or maybe we just need to move regions. I can't think of a club within 100 mile radius of me that has this facility and uses it effectively. I know of a couple of clubs who do say this but the reality is nothing like they promote. We were at a top club which we left as my daughter was forced to train while injured and was likely to do further damage or end up with a serious injury from not being able to execute a skill correctly. The club had 'access' to a physio and when we asked if we could see her, we were told that they wouldn't advise it because if the physio said to rest, my daughter wouldn't be able to compete, not all concerned about her long term health. If my daughter has ever mentioned something hurt (which normally meant it was absolutely agony and had been for a prolonged period), she was told she was just trying to skive (and generally very nastily). We eventually found a brilliant sports physio who has sorted out the chronic conditions.
What a horrendous experience. I'm so glad you removed your daughter from that. I hope you made a complaint to BG too. I'm pleased you found a better club for her.
I think they could train a reduced number of hours and still compete possibly dropping a couple of apparatus. I think the choice at the moment is all hours or nothing.
Also depends on your club of course and region. Many clubs allow older girls to drop hours and still compete. Competing a couple of pieces should also be an option. Also Team Gym is one of the best options. Most girls want to drop bars and beam. Team Gym is tumbling on a track (more giving than a floor), trampette (with and without a vault in) both to soft landing mats . And a group floor routine. Lots of fun and ideal for those older girls. All this needs to grow of course!
