When you run a martial art school, you have to be prepared for the possibility of a challenge from somebody walking into your gym.
This recently happened to UFC vet Nam Pham who was challenged by a much larger 50 year old Kung Fu Master…
Nam Pham is not the kind of person you would want to upset. He is a high level professional MMA fighter since 2001, having competed in the UFC, WEC, Strikeforce, World Victory Road, and he was even a contestant on The Ultimate Fighter: Team GSP vs. Team Koscheck.
He holds black belts in BJJ, Judo, Karate the Vietnamese martial art of Việt Quyền Đạo.
