Rener Gracie talks business with Idriz Redzovic, a BJJ Black Belt from Chicago with 22 years of experience. They discuss "loyalty" in BJJ and the difficulty of keeping students on the mat, and then Rener introduces the 2-year Guarantee that he is offering all Black Belt BJJ Instructors around the world. The Black Belt Guarantee If you’re a black belt BJJ instructor (from any affiliation), who currently owns a school, and you’re not getting the results you want, but your ego has prevented you from accepting that there might be a better way, then we have a proposition for you: Go through the Gracie University Instructor Certification Program, establish a Certified Gracie Jiu-Jitsu Training Center in your community and follow our systems for two years. If, by the end of two years, adopting our systems wasn’t the best thing you’ve ever done for your business and your BJJ career, simply let us know and we'll refund all the money you spent on instructor training and affiliation fees along
