Absolutely not. We have both kids and adult TaeKwonDo programs. The organization we are involved in, TaeKwonDo America, actually has a large amount of adult members. Many MMA fighters are also black belts. If you want to compete, TaeKwonDo is a great place to start. TaeKwonDo is also a good program for adults who want to set goals for themselves and work toward each belt.
