Which John Danaher Books Explain Leg Lock Mechanics Best?

If you're hunting for John Danaher's best material on leg locks, lean into his video and online systems rather than expecting a bunch of traditional printed books. Danaher hasn't really packaged his leg-lock philosophy in the classic paperback format the way some other coaches have; what he did do was distill the mechanics, entries, controls and counters into methodical instructional series and seminar collections. The resources you'll see referenced most often are his older DVD/online set commonly found as 'Leg Locks: Enter the System' and the more comprehensive collections usually labeled 'The Leg Lock System' on platforms like BJJ Fanatics. Those are the ones that lay out the chain of control, entries (ashi, outside ashi, 50/50, saddle/single-leg entanglement), finishing mechanics such as heel hooks, and the positional priorities that keep everything safe and effective.

What makes Danaher’s material stand out for me is how mechanical and systematic it is. Instead of a grab-bag of flashy submissions, his lessons focus on the principles: weight distribution, timing, alignment of the knee, how to lock the hips and control rotation so a heel hook actually finishes rather than just hurting a partner. His sequences show how one position naturally flows into another — for example, how failed ashi entries can be routed into outside ashi or the saddle — and he spends a lot of screen time on the little technical details that people usually miss in casual rolling. If you really want to understand why a heel hook works (and why it fails), Danaher’s step-by-step breakdowns are gold: he isolates each joint, shows the force vectors, and then layers in grips and countermeasures. Watching those segments slowly, then drilling them live with a partner, is how the mechanics click for most people I know.

If you're building a study plan around his work, start by picking one of those core leg-lock courses and commit to a focused block — a couple of weeks on entries and ashi control, then two weeks on transitions to outside ashi and 50/50, and finally a phase on finishing mechanics and escapes. Supplement that with match footage from his top students so you can see the system at play under pressure. Also, keep safety front and center: heel hooks and certain entanglements can injure training partners quickly, so tap early and drill controlled drills. Personally, mixing Danaher’s instructionals with a few seminar clips and guided sparring sessions was the fastest way I felt the concepts settle into muscle memory. Give it time and repetition, and you’ll start recognizing the positional priorities mid-roll, which is when it all stops being abstract and starts feeling like your own toolkit.
