What’s It About?
“The Science of Guard Passing” is exactly what it sounds like – a systematic, precision-based approach to dismantling even the most complex guard systems. Lepri has earned his reputation as one of the most technically sound guard passers in BJJ history, and in this instructional, he opens his playbook completely.
This comprehensive 6+ hour instructional covers every major guard type you’ll encounter, providing specific, actionable sequences for each. What sets Lepri’s approach apart is his “scientific” methodology – each technique is broken down to its fundamental principles, making them accessible regardless of your physical attributes.
Released in 2019 on BJJ Fanatics, this instructional has quickly become the gold standard for guard passing resources in gi jiu-jitsu.
Key Techniques & Concepts
Lepri doesn’t just show random techniques – he builds a complete system that works together seamlessly:
- Grip fighting fundamentals: Learn to shut down guard attacks before they even start by establishing dominant grips and breaking your opponent’s controls
- Spider guard passing sequences: Step-by-step solutions to one of the most frustrating guards to pass
- Lasso guard neutralization: Technical details to nullify this dangerous position and transition to your passing game
- De La Riva passing options: Multiple approaches to handle this popular open guard
- Half guard passing mastery: Pressure-based methods to crush the half guard and secure side control
- Pressure vs. mobility passing: When to use each style and how to seamlessly flow between them based on your opponent’s reactions
- Weight distribution secrets: The often-overlooked details that make the difference between a stuffed pass and a clean one
What impressed me most was how Lepri connects everything together. Rather than isolated techniques, he shows complete sequences – forcing an opponent from open guard to half guard, then capitalizing with a knee cut, for example.
My Experience & Key Takeaways
I’ve studied numerous guard passing instructionals over the years, but Lepri’s stands out for several reasons. The level of detail is exceptional – he doesn’t just show what to do, but explains the why behind each movement and grip.
After implementing his concepts over several months, I noticed significant improvements in three areas:
- Grip fighting confidence: His approach to establishing and maintaining dominant grips transformed my passing game. I’m no longer getting caught in complicated guard entanglements because I’m shutting them down earlier.
- Technical precision: Lepri’s emphasis on weight distribution and posture corrected several small errors I didn’t even know I was making.
- Strategic passing: Rather than forcing a single pass, I’m now flowing between techniques based on resistance, which has dramatically improved my success rate.
One detail that completely changed my passing was his explanation of hip positioning during the over-under pass. That small adjustment eliminated the space my training partners were using to recover guard.
