I talk to Priit Mihkelson who is a BJJ Black Belt with a unique take on how BJJ can be taught and learned. We discuss how Priit structures his class and sparring sessions to encourage new behaviour but in the bulk of the interview, we discuss the practice of "clapping" back to an instructor after counting 3 2 1. It ends up taking us to interesting places like how rituals are formed, how they could be reformed, evidence-based teaching practices, motivation, self-determination theory by the time we finish.
