Lucio Lagarto has done it all. He’s a Jiu-Jitsu black belt. He beat cancer (and even trained during treatment). He has one of the best records in competition of his generation. This weekend, after finishing second in the superheavy division (at 36 years old) of the European championship, he retired from the adult division. We celebrate Lagarto’s contribution to Jiu-Jitsu by learning this sneaky armbar from the closed guard. Pay attention and go train.
