The Science of Guard Passing by Lucas Lepri – In-Depth Review

Lepri teaches a cohesive pressure-first passing system that cracks modern guards.

You learn a linked passing framework that moves from knee cut to weave to long step without giving opponents easy counters. The focus is on beating lasso, DLR, and spider grips with posture, angles, and hip control. You will not get endless move dumps or no-gi variations; this is a gi-first system for passers who want principles and chains.
