I think I am going to try to do competitive gymnastics here in a month or two, what should I watch out for? I'm 18 so I don't know how long I will be able to compete or how far I will get.. Any advice is welcome 
I have no advise, but wanted to wish you the best of luck in competitive gymnastics!
Try to control your nerves. At my gym, sometimes, our coach makes everyone in the gym stop and watch someone's routine so we stay used to performing under pressure.
Also, smile for the judges.
Try your hardest, there's no other feeling like the feeling you get when you nail a routine, and you walk off the mat like you own the place![]()
