Renato Magno is an acknowledged master of Brazilian Jiu Jitsu and an expert in the choking techniques of the art. Originally from Sao Paulo, Brazil, he became an active competitor with an impressive list of accomplishments. Throughout his successful contest career, he used his profound awareness of choking techniques to submit his opponents. Magno is highly regarded as one of the top Brazilian Jiu Jitsu instructors in the world. He appears regularly on television and movies demonstrating Jiu Jitsu and self-defense techniques.
I trained with Renato at J.J. Machado's Brazilian Jiu-Jitsu studio years ago before he opened his own school. He is a first cousin of the Machado brothers so he trained with the Machados for years. He also is a black belt in Judo having started in Judo first before Brazilian Jiu-Jitsu as a kid. He trained with Olympic level Judo instructors in Brazil.
A friend of mine took many private lessons with Renato and became very knowledgeable and good at BJJ. My friend taught me. Another friend trained a lot with Renato and became very good in Jui-Jitsu.
Renato learned from all of the Machado brothers who each have their own strong points in Brazilian Jiu-Jitsu.
Also Renato trained a lot with the Gracies and especially Renzo Gracie.
