Well it does not really matter, it really depends. if you are really good or extremely competitive than you can do it for a while. But if you are like me that you get a surgery of a fractured bone or hut your self a lot dont do competitive and move to something smaller. So you can be how ever old you just have to be strong to stay with your program.
Anybody can take gymnastics classes.
anywhere from five years to one month
If you really think you like gymnastics or would like to try it. Just google your town for places to take Gymnastics and you should have places come up. Then sign up and try it out. I took gymnastics for a few years and I still love it today, but you do have to have some talent at it or it can be difficult, but it's always good to try it out! Good luck!
Why not both!? Dance will help you with gymnastics, and gymnastics will help you with dance! Gymnastics is more of a mental sport, and if you decide to quit once you move up levels and it gets too hard, you can always do dance! Trust me, if you want to do gymnastics, at the minimum take a few ballet classes. They will help you gain flexibility, pointed toes and straight knees as well as your artistry in gymnastics. If you have enough money, I advise you to take dance and gymnastics.
In most countries should take 5 years
at least 11 but you should take 12
Find a local gymnastics club and sign up!
You would need a bachelors degree which should take about four years.
