This week, we're joined by Will Weisser! Will is a jiu-jitsu black belt, co-founder of the competition-tracking site JiuJitsu.net, and author of the new book Scientific Jiu-Jitsu: A Unified Theory of Grappling. In this episode, Will lays out that unified theory: the idea that every jiu-jitsu technique exists to raise your own strength or reduce your opponent's. Topics include: relative strength, frames and misdirection, body alignment, and why being strong works.

This week, we're joined by Jesse Walker! Jesse is the head coach and co-founder of Rough Hands BJJ in Louisville, Kentucky, and a frequent BJJ Mental Models collaborator. In this episode, Jesse makes the case for loading a joint with tension before you ever start the breaking mechanics, so the finish takes a fraction of the effort. Topics include: adding traction before the break, the order of operations of a joint lock, backing up to retighten a loose position, fixing the much-maligned Americana, and leglock safety through control.

This week we're joined again by Rob Biernacki! Rob is the head instructor of Island Top Team and the mind behind BJJ Concepts. In this episode, Rob breaks down how he built a working no-gi version of the lasso, a position long considered gi-only. Topics include: minding the gap in no-gi grips, the inverted grip, the omoplata as a control system, wedging, and hybrid lasso guards.

This week, we're joined again by Chris Wojcik! In this episode, Chris rebuilds his approach to the Woj Lock around a few guiding concepts instead of a catalog of techniques. Topics include: the three points of control, proximal vs. distal control, redefining what counts as fundamental, and training leg locks through games instead of memorization.
