Anyone who has done martial arts for awhile knows that finding a good school can be tricky. After all, the belt system is hardly standardized, making it hard to go by, and there's all sorts of credentials instructors can throw at you. That said, I'm very impressed by the Five Rings Dojang. Master Mase not only has the experience, but he has credentials that would impress anyone. As far as the actual classes go, the school is located in a larger gym, a membership to which will be part of your tuition. To me, this is pretty awesome, as I can get myself nice and tired before class with some cardio, and climb the big rope next to the mat between classes for some additional punishment. In addition to the location, Master Mase can be very creative with the lessons, especially in Krav Maga, bringing to the table drills that will make you dig deep for the strength or sheer force of will to succeed. Tang Soo Do classes are composed of students of all ages, which was a little unusual to me, but there's usually enough students of each age group (child, teen, adult) that nobody is paired with a partner vastly different in age/size. Overall, I recommend it to anyone interested in one or both of the arts offered at the school.
