I talk to Steve Kwan. Steve is one half of the excellent podcast BJJ Mental Models, he is also a Brazilian Jiu-Jitsu black belt and works professionally at a tech company improving efficiency in process and operations. We discuss how he has taken lessons learned there and with the use of mental models how they can be applied to learning techniques and making decisions for jiu-jitsu. Also, how parameters and constraints can benefit learning and if the influx of information from social media and instructional could possibly benefit or harm the growth or development of Jiu-Jitsu training.
