konnichiwa! In this episode of the Martial maze martial arts podcast, we asked a question. Can you buy a black belt in Brazilian jiu-jitsu? It's beginning to look like the commercialization of Brazilian Jujitsu is going the way of commercial Karate. We take a look at Brazilian Jujitsu's newest black belt Derek Moneyberg. After only training in Brazilian Jujitsu for 3 1/2 years, he received his black belt. Some say he's not legit other say he is we'll leave this for you to decide. We hope you enjoy.
