Every grappler knows the feeling. You’re three minutes into a five-minute round. You're stuck under a heavy side control, and suddenly, your lungs feel like they're burning and your limbs feel like concrete. You’ve gassed out. When we talk about improving our "gas tank" for Brazilian Jiu-Jitsu, the scientific term that often gets thrown around is VO2 Max . But what actually is it, does rolling improve it, and what are the best tools off the mats to make sure you aren't drowni

OK, this is a long one. Starting Brazilian Jiu-Jitsu can feel like diving into the deep end of a pool when you've never learned to swim. You'll be tapped out countless times, feel completely lost during technique demonstrations, and question whether you're cut out for this martial art. The truth is, every BJJ practitioner has been exactly where you are now. The difference between those who thrive and those who quit within their first year comes down to understanding what you'

Charlie Munger, Warren Buffett's legendary investing partner, was famous for his mental models—frameworks for better decision-making. One of his favorites was the inversion principle, summarized by his maxim: "Invert, always invert." The concept is simple but powerful: instead of only thinking about how to achieve success, flip the problem around and think about how to guarantee failure. Then, systematically avoid those failure modes. The idea came from mathematician Carl Jac

The leg lock era is hailed as BJJ's greatest evolution. But what if it was really a very public confession about decades of wilful blind spots? By The Jiu-Jitsu Foundry  ·  April 2026  ·  9 min read  ·  Petaling Jaya, Malaysia The BJJ leg lock revolution — fuelled by the Danaher Death Squad, EBI rulesets, and a wave of heel hook-savvy no-gi competitors — is one of the most celebrated turning points in grappling history. The community tells a satisfying story: the art evolved,

You're in side control, and your opponent makes their move—they frame against your shoulder and try to create space to escape. The obvious response is to pressure down harder, crushing their frame. But what if that's exactly what they want you to do? What if they're baiting you to overcommit so they can slip out the back door? This is the difference between first-order and second-order thinking in Brazilian Jiu-Jitsu. Second-order thinking is a mental model that looks beyond

Every BJJ practitioner has experienced it: you spend months learning dozens of techniques, yet when you roll, you find yourself relying on the same handful of moves. You might feel guilty about it, wondering if you should be using more of your arsenal. But what if this natural tendency is actually pointing you toward a more efficient path to improvement? Enter the Pareto Principle, better known as the 80/20 rule. Named after Italian economist Vilfredo Pareto, this principle s

The Unspoken Contract Every time you slap hands and bump fists, you're entering into an unspoken agreement. Yet somehow, we've all been there: you're settling in for a technical flow roll, and your partner explodes into a scramble like it's ADCC finals. Or worse, you're trying to sharpen your competition timing, and your partner goes limp, treating every submission attempt like a yoga pose to breathe through. The "sparring vibe" is perhaps the most important—and most ignored—

The Brazilian Jiu-Jitsu community prides itself on a culture of openness. The idea that a grappler can travel anywhere in the world, find an academy, and be welcomed for a roll is a beautiful and enduring part of our martial art's ethos. This "open door" policy is often seen as a non-negotiable pillar of BJJ culture. But what if we, for a moment, played devil's advocate? What if we questioned whether this policy, in its most absolute form, truly serves the best interests of a

When Royce Gracie stepped into the octagon at UFC 1 in 1993, few spectators understood what they were witnessing. The slender Brazilian, weighing barely 170 pounds, systematically dismantled larger, stronger opponents using a ground-fighting system that seemed almost alien to the striking-dominated martial arts landscape of the time. That night didn't just launch the UFC—it ignited a revolution that would fundamentally reshape how fighters train, compete, and think about comb
