I started two 5 year old twin boys in in 1 day a week gymnastics and 1 day a week tumbling course for ages 5-7. They are the only boys in the class, with the rest of the class being girls.
I'm coming to the sport entirely green but a life long wrestler & wrestling coach.
I had them join gymnastics/tumbling as I had read a bunch of reports about how it has probably the highest level of cross-over skills.
The gym we are at is pretty discouraging in regards to the fact that boys are not allowed on any form of competition team. As of right now I don't mind it, they are beginners, 5, and I'm just not that eager to be pressured into hotel stays and such to compete in meets. But if it grows into something they enjoy (as of now they both like it) it's hard to imagine it being something we will stick with when you aren't allowed to compete and the coaches clearly prefer to focus their attention on just about anyone else beings they can enter competition.
At this point I'm guessing we will be on a two year plan where we try and gain some balance and coordination skills, but without any prospect of being allowed to compete down the road without going to a different club 40 minutes away, I just don't see how their interest in it can be sustained which is disappointing.
