Hi, I have just joined a school. I picked TKD because I studied it in college and also because this school is five minutes from my house. Yes, there are some young black belts there, but the owner/instructor is highly recommended, has commendations from U.S. Marshals and State police training divisions. I like the culture and staff and other members, and they have been there for several years. According to the staff, it is 4-5 years to attain black belt. That seems demanding enough for me. I want to train for fitness, confidence, and goal-setting. Anything else I should look for in this school? How can I check them out further, then? Thanks!
