After my old professor sold his gym to Cobra kai, I wasn't sure if I was going to stay. Our old professor had a talk with us and told us the main professor Sim go, won't teach all the classes and we will have different professors on certain days ((in reality it's only 2 times a week, other than that it's Sim everyday)). We didn't like that at all. We were all use to having one professor at all times. I decided to give it a try. At first it was very intimidating, because there were A LOT of guys and some of them were big, but as I kept going, I felt more comfortable. Everybody there is really nice! They made me feel welcomed....and about having different professors, well damn, it's the best thing, I HAVE EVER experienced. All of my professors have a different bjj game, so it's very interesting learning different techniques from different black belts. I believe it has improved my jiu jitsu a lot. I am glad my old professor sold it to Cobra Kai and no one else. I HIGHLY recommend COBRA KAI!
