Brazilian Jiu-Jitsu

Overview
Brazilian Jiu-Jitsu (BJJ) is a grappling martial art derived from Judo and Kodokan ground fighting, developed in Brazil by the Gracie family in the early 20th century. It focuses on ground fighting, submission holds, and using leverage and technique to control opponents larger than yourself. The core premise: a smaller person with better technique can defeat a larger, stronger opponent on the ground.
Jack tried it on March 28, 2026, per his Notion meeting notes from that day which include the action item “Try Brazilian Jiu Jitsu tomorrow.”
How It Works
BJJ training happens in two modes:
Drilling: practicing specific techniques repeatedly with a partner. Takedowns, guard passes, sweeps, submissions. Drilling builds muscle memory. You do the same movement hundreds of times until it becomes automatic.
Rolling: live sparring. You attempt to submit your partner (with a choke or joint lock); they attempt to submit you. Both parties tap when caught in a submission. Rolling is where the technique gets tested against a resisting opponent.
The transition from drilling to rolling is a shock for most beginners. Techniques that worked smoothly in drilling suddenly fail completely against someone who doesn’t cooperate. This is by design: BJJ doesn’t work unless the other person fights back.
The Learning Curve
BJJ has one of the steepest learning curves of any martial art. A complete beginner walking into their first class will be submitted repeatedly by white belts who’ve been training for 6 months. By blue belts, the submissions come faster and from positions you didn’t know were dangerous. Purple belts can control you so completely that you feel like you’re wrestling with furniture.
The belt progression is slow by design: white → blue → purple → brown → black. The average time from white to black belt is 10+ years. Most other martial arts have inflation in their belt systems. BJJ does not.
This maps onto a pattern Jack engages with elsewhere: Electric Unicycle has a steep learning curve and punishes you physically when you fail. Philmont 2019 was suffering-as-instruction. The Philmont Medium post is about what difficulty teaches you. BJJ is in the same category.
The Gracie Family and Brazil
BJJ was systematized by Mitsuyo Maeda, a Japanese judoka who emigrated to Brazil in 1914, and passed on to the Gracie family - particularly Carlos and Helio Gracie. Helio, who was physically small and sickly, adapted the techniques specifically for leverage over strength. The art that resulted was explicitly designed to give smaller people a method of self-defense.
The Gracie family then marketed BJJ through the Ultimate Fighting Championship (UFC), which they co-founded in 1993. Royce Gracie won the first three UFCs against larger opponents from various martial arts backgrounds. This demonstrated the effectiveness of ground grappling to a global audience and launched the modern BJJ boom.
BJJ and the Tech World
BJJ has an unusually high adoption rate among tech founders, VCs, and engineers in Silicon Valley. The overlap is noted enough to be a cliché. The reasons hypothesized: BJJ rewards intelligence and systematic thinking over raw athleticism; the ego-check of getting submitted by smaller/older/less athletic opponents builds a specific kind of humility; the physical engagement with a resistant partner is a complete break from screen-based work.
Mark Zuckerberg competing in MMA (and training seriously) is the most visible tech-world BJJ story of recent years. He trained BJJ before entering MMA competition.
