Introduction to single leg X prevention and fundamental counters to single leg x options.
This is a well explained video, that will help save me from accidental injury!
great
Professor B. F. shows his take of leg lock prevention with accuracy. He really points out the key concepts and key points added up with a proper amount of details so that you can get it quite quick
Bjorn's stuff is always good. This one is no exception. It's a fresh take and easy to implement.
Less expensive video offering many of the techniques found in more expensive videos.
very good
Preamptive Defence us thé key
very good info for a very good price (free)!
As an older martial artist, I appreciate the premise of this instructional which is to prevent your opponent from getting close to a submission. Not really about escapes, so much as interrupting your opponents intention of getting you to a position in which they can apply some form of leglock. The video is well shot and easy to follow.
This was a VERY GOOD instructional! It may not go as noticed because BJJF has so many instructionals from powerhouse names...but you can definitely improve your leglock defence by checking out this very worthy instructional from Friedrich
Short and sweet, priceless info here!
Little tips and tricks for prevention.
Another great Instructional!
Good
It is as important to be able to defend leg locks as it is to apply them. The poularity of the leg lock game makes this imperative currrently.
Pretty good system to avoid and defend some of the common positions that lead to leglocks.
I have over two dozen BJJ Fanatics instructional videos and have never fund any of them lacking in sound technique instruction. All BJJ Fanatics videos and concise and easy to understand. I would recommend this site to all BJJ students of any belt level.
Great
Great series of instruction.
Actionable approaches and system to prevent leglocks
Definitely worth a watch
Great work 👏� 👍� :ok_hand:
one of the best leglock instructionals I've ever seen.
The Problem with Late Stage Leglock-Escapes is: Everybody knows them and calculates them into a Attack-Chain. For Example, Standard Heelhook-Defence often opens up a Footlock and so on. So the second or third Attack will come through. Bjorn focusses on shutting down the Entry-Positions themselves. So the Attack-Chain can never start.
