Coach René and Matt dive deep into the murky waters of martial arts styles — how they form, when they splinter, and whether most of them are legit or just marketing. From Kyokushin breakups to Bruce Lee philosophy to the origins of Gracie Jiu-Jitsu, this episode pulls no punches. You'll hear wild legal battles over the word "karate," stories of cult-like traditions, and what makes a “style” actually different from its parent art. Plus, why Coach René no longer calls what he teaches Brazilian Jiu-Jitsu, and a moving tribute to a fallen grappler.
