Leglocks: Enter The System by John Danaher

Excellent

This series by Mr. Danaher is a comprehensive introduction to the leg lock attack game. Everything is clearly explained, including the reasoning behind the techniques, philosophy, and mechanics of all aspects. For older folks like myself, it's an eye-opening view of the dangers and opportunities a hobbyist and professional has at their hands (or feet).

Amazing!

Phenomenal clarity and explanation! Definitely has helped my leg lock game.
