We are at the Peaceful Dragon 4-5 times per week for Kung Fu, Tai Chi, and seminars on Chinese medicine and philosophy.
Our 10 year old has been going for 5 years and is now working towards his junior black sash. Our 7 year-old just started, and wants to take classes every time they are offered. Both are members of the Leadership Club and are currently reading "The West Point Way of Leadership" as part of their training.
I have been taking Tai Chi and Kung Fu for a year now, and have lost 20 pounds, plus have gained much greater strength, stamina, flexibility, and confidence.
Classes are more than what you might pay at a strip-mall martial arts school, but you are getting a richer, more vibrant community and a more robust training.
