Bryan Rumble is a 2nd degree belt and a working scientist. In this episode we start out by talking about BJJ traditions, the depth of the art, and how the scientific method might be applied in jiu-jitsu.
Then, at about the 23-minute mark, Bryan and I nerd out SUPER hard on Dungeons and Dragons and how it relates to martial arts training. You’ve been warned!
