It is a mixed martial arts school. BJJ, Thai Kickboxing, Karate. The instructors are 30'ish and are very in shape and seem to be extremely competent and aggressive. As corny as this franchise may seems to be they are actually having some students qualify for the Golden Gloves championships. Thats' says alot as thats no joke, especially for a Mixed martial arts school. Tournament wise TSK seems to do very, very well. I'm kinda torn as I like the school and the class I tried out. Very clean, very structured and yet tough. I'm gonna try another school and see how it compares. A school run by kickboxing legand Louis Neglia. I do have some reservations about studying too much of just that discipline.The head instructor at TSK said to me that the school is expensive but reminded me that there really isnt many mixed martial arts schools that cover these different styles as extensive as TSK. Looking around the Brooklyn area there really arent any to be found. Are good mixed martial arts schools normally more expensive then a typical TKD or kickboxing school?
