This week, we're joined by Beatrice Jin! Beatrice is a black belt competing in the IBJJF top 10 at lightweight and middleweight, and she's known across jiu-jitsu social media for her whiteboard reels. In this episode, Beatrice breaks down the 90% of jiu-jitsu that has nothing to do with sparring, and why the work around the mat is what actually builds a career. Topics include: what podium finishes actually feel like, building a women's open mat from three people to thirty, finding the niche only you can fill, and using social media to build trust before asking for the sale.

This week, we're joined by Josh McKinney! Josh is a black belt, head coach at HeadNod Jiu-Jitsu in Southern Illinois, and the host of the I Suck at Jiu-Jitsu podcast. In this episode, Josh shares a framework for self-coaching beyond getting belt promotions, and explains why submission count and belt color are the wrong yardsticks for measuring whether you're getting better. Topics include: false metrics, the over-reliance on your A-game, learning to read old-school black belts, the Henry Akins "how many steps" test, and managing effort as a progress metric.
