This week, we're joined by Nelson Puentes! Nelson co-founded Inverted Gear and runs Inverted Gear Academy in Allentown, Pennsylvania. In this episode, Nelson explains his Super Mario theory of jiu-jitsu: a good game teaches you how to play it by raising the difficulty one step at a time, and a good jiu-jitsu class works the same way. Topics include: game design, resource management, coaching without instructions, defensive jiu-jitsu, and intrinsic motivation.

This week, we're joined by Rob Cole! Rob has been training martial arts for over 35 years, 25 of them focused on grappling, and he coaches at Ascension Athletics in Connecticut, where he runs his practice through the ecological dynamics framework. In this episode, Rob explains the intention-led approach, where you give students a goal to work toward instead of specific things to focus on. Topics include: a plain-language primer on ecological dynamics, intention versus attention, win conditions as a driver of behavior, grip fighting as a warm-up, teaching leglocks without fear.
