My name is Isaac Rosen they call me "A Cobra" (the snake) and I am an orange belt in Braziliian jiu jitsu. I am also a green belt in Judo under professor Mark Hildago and a brown belt in Kempo Karate.

I am 9 years old and I train 6 days a week in Braziliian jiu jitsu.

My black belt instructor is Rodrigo Meideros at BJJ Revolution Team in San Diego. I also take private lessons from Rodrigo Meideros and Clark Gracie.

My dad takes me to the UFC MMA(Mixed Martial Arts) events all the time.

I know a lot about mixed martial arts and I have worked out with Chris Leben and Diego Sanchez. I'm pretty tuff.
