I coach teens, all are between ages 11-18. I have learned through the hard way that you have to give your gymnasts be teens. They are allowed or even encouraged to miss practice for important events like birthdays, proms, school events or summer festivals. The older they get, the more free time they need. Nothing is more upsetting than having a teenager at practice when she clearly would rather be in a school event that everyone else are going. They are already missing a lot of "normal life" to go to meets and camps. Missing an occasional Saturday practice is not the end of the world in the big picture. And that's what we often forget - the big picture. When I find myself worrying about a gymnast who is not at practice, I always try to remind myself to be happy about the ones who are there and who want to be there and focus on them. I also remind myself that we are doing something right (not just me but their former coaches too) because none of these teen gymnasts have quit during this year or last year, or even the year before that unless there has been a serious injury that ended their career. And those who had to quit didn't want to.
I think we are doing some things very differently compared to many clubs here. The other clubs don't really seem to have gymnasts older than 16. They put all their time and energy to little hot shots and rising juniors. They train super high hours and missing practice is a big issue for many coaches. We have hardly 35 senior (older than 16) gymnasts in this whole country and I think it's sad. Most kids quit before they hit high school.
I try to keep the practices fun, but of course it gets repetitive sometimes. I like to mix the training (warm ups, conditioning, stretching) up every 6 weeks to keep it more interesting. I listen to gymnasts and keep the things that they like. If they like more circuit type conditioning then circuit it is. I let the gymnasts have a lot of input on their own routines, skills they work on etc. I talk to them all the time and encourage them to talk about their lives, school, friends, family. If I see that someone is upset or very tired, I give them an option to go home early very easily. I believe that making them feel like humans, not just gymnasts, makes them want to come back day after day. I also always remind them that this is just gymnastics, so nothing that happens here or at a meet is end of the world. This is just a sport and what ever happens, they are getting good exercise, having awesome time with their best friends and learning life skills. That's all that matters.
