“The single best resource or instructional on leglocks I’ve ever seen”

After years of research and development The Modern Leglock Formula with Rob Biernacki and Stephan Kesting is out!

This ultimate guide to leglocking in the modern era by these two well-known BJJ black belts instructors is available both as a 6 DVD set, and also in an online format that you can access instantly on your computer, phone, or tablet.

This resource will give you a proven,step-by-step system for safely adding ultra-effective lower body submissions to your game. Now you can add the same leglock techniques and strategies that have transformed the grappling scene to your own submission arsenal.

Leglocks Are the Great Equaliser

Leglocks are the hottest area of jiu-jitsu right now, and that’s for a good reason…

They are the great equaliser and give you a totally unfair advantage on the mat. Leglocks allow you to go against people who should be completely dominating you, turn the tables, and tap them out instead.

Leglocks are the easiest way to submit a more experienced grappler.

We’re at a funny stage now in jiu-jitsu… There are lots of grapplers who are super skilled at the traditional upper body submissions but are still absolute beginners at leglocks. It’s not the way it should be, but many BJJ black belts are wizards at armbars and triangle chokes but only white belts when it comes to understanding the lower body game.

This creates a HUGE opportunity for you right now to submit higher belts. All you need is to know what to do.

The leglock game is a very technical battle, and a little bit of knowledge goes a long way. So having even a bit more knowledge in this area than someone else allows you to move into attacks confidently, knowing that he probably won’t have an answer to them.

It’s simple: if your opponent has ignored leglocks then you’ll be able to tap him easily, even if if he’s been training three times longer than you have.

Leglocks are also the best way to tap out someone much stronger than you.

Bigger, stronger guys are always scary. Even if you catch them in a submission then they can often just power out of it. For example, a big guy can literally bicep curl his way out of an armbar, and someone with a really thick neck can often survive your triangle choke.

One excellent answer is not to even engage them in an upper body battle of strength. Instead change the game and go to the legs.

First of all, it’s much safer. Once you catch someone in a leg entanglement it’s extremely difficult for him to get to their feet and get his weight back on top of you. That’s because you’re controlling his legs and his base until the the exact moment that you attack with your final submission.

And then, the best part is that size is no defense against a properly executed leglock.

That’s because with modern leglocks you attack the smallest portion of his leg – the tiny muscles and ligaments that don’t scale up with size. And you’re doing it with your biggest, most powerful muscles.

It’s a totally unfair contest, one you’re going to win every time.

The Leglock Game is Changing.

Leglocks have been around a long time, but in the last few years they have become much more sophisticated, powerful, and effective.

New strategies and transitions have been developed. The control positions have been refined. And the actual submissions themselves are now applied in a different way that requires much less strength.

These innovations have resulted in leglocks becoming the dominant submission in no gi grappling competitions like EBI, Polaris, and ADCC (plus they’ve had a resurgence in MMA as well.)

So in the modern era you can’t only attack half the body!

Like it or not, the leglocks are coming.

And when it comes to defense, then it’s only a matter of time until someone jumps on your legs. If you don’t know the lower body game then you’re going to end up tapping out multiple times in a single sparring session, or losing that big competition just a few seconds after stepping on the mat. You don’t want to end up in a submission that you have NO idea how to defend.

You just can’t stick your head in the sand and hope that this part of jiu-jitsu goes away.

The difference between success and being left behind here is knowledge. Knowing what to do gives you options, both when it comes to leglock attack and defense.

You don’t want to be left behind in this area of jiu-jitsu.

Who Am I?

My name is Stephan Kesting. I’m the producer and co-teacher of The Modern Leglock Formula.

I’m a BJJ black belt and have been doing martial arts for over 38 years, including many grappling arts like sambo, judo, submission wrestling and shoot wrestling.

I’ve been teaching online for a long time. My Youtube videos about BJJ have over 55 million views, I’ve sold tens of thousands of instructional DVDs and apps, and millions of people have visited my Grapplearts website.

The very first leglock I ever learned was shown to me by Dan Inosanto in the early 1990’s, and since then have trained extensively with leg lockers like Erik Paulson, Oleg Taktarov, Marcus Soares, and others. So this has been an area of special interest to me.

Leglocks have allowed me to beat BJJ black belts, win competitions and feel like there was an ace up my sleeve when I was facing a really tough opponent.

So with all that leg lock experience let me be really emphatic…

The Modern Leglock Formula is the single best resource or instructional on leglocks that I’ve ever seen”.

It’s changed the way I approach the lower body game and has made it much more efficient, effective, and powerful.

What Exactly Are You Getting in the Modern Leglock Formula?

Modern Leglocks Formula is a complete A to Z system for mastering modern leglocks. It is the single-most complete instructional on effective leglocks ever published, with over 10 hours of instruction taught in clear and simple ways using with multiple camera angles for maximum visibility.

The material is logically arranged into 10 volumes (which fit onto 6 dual layer DVDs if you end up getting the physical disks).

If you’re new to leglocks then for the fastest bang for your buck I suggest starting with volumes 1, 2 and 3. With just those 3 volumes under your belt you’ll already be lightyears ahead of most of your teammates. After that the remaining 7 volumes will allow you to go as deep as you like into the leglock rabbit hole. All of a sudden you’ll start seeing leglocks everywhere you look and have more than enough material to get your ‘black belt’ in lower body submissions.

Here’s a quick breakdown of the 10 volumes…

Volume 1, The Biomechanics of Breaking a Leg (Leglock Theory)

Understanding the details behind the scenes when you apply a technique will make those techniques MUCH more effective. It’ll also make all the details easier to remember, because instead of just memorising steps in a move you’ll understand the reasons why you’re doing each step.

This volume is a super-practical breakdown of the concepts that separate the leglocks applied by recreational players and elite, world class competitors. These principles will make all your leglocks MUCH tighter and more effective.

Volume 2, What are the Best Leglock Positions (Leglock Taxonomy)

This volume takes you through the very best leglock positions, explaining the little tweaks that make it completely impossible for your opponent to rip his leg out of your clutches.

The details you’ll get in this volume will instantly make your leglock entanglements feel much, much tighter. And you’ll be able to instantly choose the exact right type of leg entanglement to deal with any opponent you might might run into.

Volume 3, How to Actually Finish a Leglock (Dig and Breaking Mechanics)

If people know that you’re going after their legs the first thing they’ll try to do is to hide their feet, kick your grips off with his legs, and do anything he can to prevent the leglock. Fortunately you’ll learn super-powerful ways to get your preferred grip no matter what your opponent does.

Also we also cover the exact grips, adjustments, and body mechanics that’ll make your opponent’s foot feel like it’s about to explode. These are the hidden adjustments that make it easy to finish someone even if he’s twice your size.

Volume 4, How to Get into a Leglock from Anywhere, Top or Bottom (Leglock Entries)

This is a huge volume, and in it you’ll get ways to get into the leglock entanglements from almost every position in jiu-jitsu.

With these techniques you’ll be able to hit leglocks regardless of whether you’re on top, on bottom, passing the guard, attacking from the guard, or in a scramble. Your opponents will never feel safe again!

Volume 5, Moving Between the Major Leglock Positions (Leglock Transitions)

One of the core concepts in the Modern Leglock Formula is improving your position. You want put your opponent into worse and worse positions until escape is impossible and you can apply the finishing leglock at your leisure and with complete control.

This amazing volume is full of transitions that your opponent won’t expect and will be unable to stop.

Volume 6, How Escape and Prevent Leglocks Done to You (Leglock Defense)

In the modern grappling environment it’s getting easier and easier to run into a really good leglocker and find yourself on the defensive. But just because someone’s going after your leg doesn’t mean that you need to tap out… if you know what to do you can escape and turn the tables on your opponent.

Using the techniques and concepts in this volume you’ll easily start preventing and defending leglock attacks you once thought were inescapable.

Volume 7, Advanced Transitions Against Common Escape Attempts (Advanced Leglocking)

As you become known as a leg locker people will start to develop defences and get better at escapes. But each escape attempt can be a new opportunity for you if you just know what to do.

This section focuses on the advanced techniques and transitions that you can use to take advantage of your opponent’s attempts to escape your attacks.

Volume 8, Transitions to Passing and Upper Body Attacks

In this volume you’ll learn how to follow up if your leglock attacks just aren’t working. You’ll get the techniques you need to transition from different leg entanglements to get to the top, pass the guard, and take the back.

This ability to combine lower body and upper body attacks is the sign of a complete grappler.

Volume 9, Passing the Guard of a Leglocker

It can be scary to enter the guard of a skilled leg locker because you know you’re only one move away from getting submitted. Screw up even a little and you’ll be caught in a heel hook, toe hold or kneebar.

There are right and wrong ways to pass the guard of a leg locker. The techniques and strategies in Volume 9 will keep you safe while also allowing you to cut right through the guard of leglock specialist.

Volume 10, Specialty Leglock Situations

In this section you’ll learn escapes from difficult positions and submissions that take you directly into devastating leglocks. Make your opponent pay for even thinking that he was going to tap you out!

Limited Time Bonus Offer (A $97 Value)

The Single Leg X Guard (SLX) is a guard position used in BJJ by top fighters like Marcelo Garcia, Leandro Lo and many others.

Superficially it is similar to the ‘Ashi Garami’ leg entanglement position in modern leglocking, although the focus is almost 100% on sweeping your opponent instead of immediately submitting him.

The thing is that the SLX and the leglock game are like a jab and a cross; they go incredibly well together.

If you combine the techniques and strategies of the SLX together with your newfound leglocking knowledge then you’ll really have the best of both worlds. Your opponent won’t know whether you’re submitting him or sweeping him.

So here’s the deal…

If you order the Modern Leglock Formula today I’ll also give you instant online access to my entire Single Leg X Guard Masterclass online program, normally a $97 value, for free. You’ll get an email with login details about 10 minutes after you complete your leglock purchase.

This bonus won’t last forever, so please move quick if you want to get this additional training for free.

Frequently Asked Questions

Q: What formats is The Modern Leglock Formula available in?

A: It is currently available in a 6 DVD set (most of those DVDs are dual layer to fit all the information) and in an instantly available streaming format on Grapplearts.com. As part of the initial launch we’re offering an option of getting both the DVDs and the online version for the price of just the DVDs.

Q: Is this an app, or will a series of apps with this material become available in the future.

Firstly, the on-demand digital version plays very well on smartphones and tablets anywhere that you have data or a wifi connection.

But if you prefer the information in app form then go and grab The Grapplearts BJJ Master App for Android and iOS (it’s free).

Q: Are leglocks safe?

A: The modern system of leg locking is much safer than old school leglocks for two main reasons…

First, it focuses much more on getting to and controlling the leg with one of the fundamental leglock control positions. In fact you and your partner can spend an entire sparring session just going for and maintaining a dominant leglock position and never actually cranking the actual submission itself.

And secondly, the modern approach to heel hooks focuses on immobilising the the knee and attacking the ankle instead. That makes it possible to apply the submissions slower, with more control, and not apply them against the vulnerable knee joint.

The 10 modules of the Modern Leglock Formula can be found within the Grapplearts BJJ Master App, which is free to download for both Apple and Android phones or tablets.

A Final Word from Stephan Kesting



I’ve done a lot of leglocking in the past and I still think that The Modern Leglock Formula contains a TON of stuff I didn’t know. In doing this project with Rob Biernacki I learned techniques, concepts, drills and transitions that made my leglock game more reliable and way more effective.

Bottom line: it really is the best product on the market for learning this aspect of grappling.

Good luck with your training, and happy leglocking!!
