I retired from gymnastics at age 16. After I was married and had my son, when he was two years old I decided to do gymnastics again to get back into shape. I was 22 then. At age 34 I became State Champion on balance beam, vault and floor exercise, won third place on bars and won Silver All-Around missing Gold by .05! I competed at Level 8 in the USAG Junior Olympic Program in the 16 years old and up Division.
If you have the passion, the desire to be the best you can be, age is no limit. The Senior Olympics does not even have gymnastics in it! I wish it did. You must be 50 years old to compete in the Senior Olympics. I'm now 49 and desire to compete once again but this sport makes it very difficult, unfortunately, for adult gymnasts to succeed and follow their dreams. It's not just a little girl's sport!
My advice is, if you love gymnastics, don't let anyone stop you from doing it. I wish the best for every gymnast that has a dream and is willing to go for it, no matter what!
