Jeff Yumul is the owner of Iron Jiu Jitsu and a black belt in Brazilian Jiu Jitsu under Pete The Greek here in Chicago. Jeff's student Victor who instructs beginner classes also joined us on the podcast. Jeff also offers weekly yoga classes and recently hosted Nicky Rod for a no-gi jiu jitsu seminar. If you are in Chicago then you definitely need to stop by his Saturday Open Mat from noon-2pm that is free to everyone.
