Knowing how to defend, escape, and counter the heel hook leglock attack is super important. In this excerpt from https://www.grapplearts.com/modern BJJ black belts Matt Kwan and Rob Biernacki show how the berimbolo can be applied to defend and even counterattack the heel hook when your opponent has you in ‘ashi garami’, the most common and popular entanglement for leglocks. The berimbolo isn’t just a guard attack – it can be used to escape many different situations in both gi and no gi grappling.
