Ep. 411: The Fragmentation of Jiu-Jitsu, feat. Jeff Serafin

This week, we're joined by Jeff Serafin! Jeff runs Serafin Brazilian Jiu-Jitsu out of Gym 1801 in Evanston, Illinois, and has been training jiu-jitsu for almost 30 years. In this episode, Jeff talks about the fragmentation of the jiu-jitsu community, and what coaches and students can do to bring it back together. Topics include: gi versus no-gi tribalism, ecological versus traditional training, gatekeeping, and cross-training.
