I do gymnastics at the Y too because it's a heck of a lot cheaper than all the other gyms in my area and they don't require that we are absolutely at every practice all the time. We have kids who are in plays and a couple girls who miss practice once in a while due to homework.
Our gym is small. One vault, one set of bars a foam floor, and a total of four beams. We have one high beam, one thats ~6 inches lower than that, a low beam and what we call the "super low beam."
levels 5-6 practice six hours a week during the school year. All our optionals moved gyms when our head coach quit, but I think they only did nine hours. We have a super laid back attitude in general. We have a really small team right now (three six's, five fives) so we have never come close to winning a meet though.
The perks of gymnastics at the Y is being able to have a life outside of gymnastics at the same time. I am taking three college classes, I'm a cheerleader, and I play in the pep band for school. I have a 4.0 gpa and I still manage to fit gymnastics in, thats why I love my gym.
