The kneebar to be the king of leg submissions: you are attacking one of the largest and most injury suseptible joints in the body. The kneebar has a higher finish rate than the heelhook or toehold, both often being lost do to sweat. Also, unlike heelhooks and toeholds, which often need to be applied gently in training to avoid injury, the kneebar is a fairly safe submission when applied properly.  To develop this submission into an effective attack you will want to be aware of three common errors to avoid when practicing and applying the kneebar: incorrect body position, lack of control over your opponent’s leg, and insufficient knowledge of counters.

1 – Wrong Body Position

The most common mistake with the kneebar is probably poor body position.  In this attack you need to use the power of your whole body against the knee joint. If you use your body inefficiently, then your ability to generate power is limited, and the submission takes longer to apply, or may not even work at all.

When applying the kneebar your body should NOT form a straight line.  In a stretched-out position you have limited ability to arch backwards, and you cannot use the power of your hips properly. To apply the kneebar from this position is like trying to bridge a mounted opponent off of  you with the back of your legs flat on the floor: very, very difficult!

To be in the correct body position for the kneebar, your body should  be positioned with a 90 degree bend in the knees and a 90 degree bend  in the hips. This is your ‘power position’: from here you  have much more ability to arch backwards while applying the kneebar, as  well as being able to use the power of your hips. This is basically the same position you would need to be in if you wanted to bridge off a mounted  opponent. In this position you will be able to bring the full force of your body to bear against his knee joint.

Try a little experiment: put your training partner in a kneebar and keep your body absolutely straight. Now see how far you can bend backwards,  as if you were applying the kneebar. Then try this again, but start in the power position: you might be amazed at how much further back you can arch, and how much further you could bend his leg if you had to.

2– Insufficient Foot and Leg Control

Foot and leg control is required to prevent your opponent’s leg from rotating or escaping into a safe position. In order to attack a limb  you usually need to control it first. Too often one sees a kneebar attack where the defender manages to escape the lock due to insufficient foot  and leg control.

Control over the leg is generated by using your legs, your arms, and  your head. There are many variations for these methods of control, so  I will only address the basics of each control method. There are of, course, variations and exceptions to these ‘rules’, but before you go breaking the rules you first have to learn them.

The two most basic ways to position your legs are: 1) with your ankles  crossed on his butt, and 2) with your legs triangled to the outside of  his leg. Pinching the legs together as hard as you can is very important: this limits his movement and makes the lock come on faster.

Your arms should hold his foot close to your body. If you are holding  his leg at arms length from you then you don’t have as much control  over his foot. Furthermore you will be using more arm power instead of  legs and back power to apply pressure. Generally speaking, you should  hug his leg to your chest when applying the kneebar, but placing his leg under your armpit is also a good control position.

An important, yet often overlooked detail, is the position of your head.  If you get the chance, place your head above your opponent’s foot,  trapping his foot between your head and the floor. This limits how much his foot can rotate, and really cuts down escape options. There are, of course, exceptions to this rule, but try incorporating this detail into your kneebar attacks and see how much more efficient they become!



3 – Insufficient Knowledge of Counters

‘Why should I learn the counters’, you might ask: ‘I want to learn how to apply kneebars, not to get out of them’. Knowledge         of counters, and counters to those counters is critical to mastering any  technique. It doesn’t matter if we’re talking about kneebars, armbars, pin escapes, or takedowns – you have to understand what  your opponent’s options are and what to do if he tries to counter  you.

There are many different counters to the kneebar, including triangling  the legs, leg prys, cross-faces, spin outs, etc. I encourage you to learn and experiment with as many different counters as you can. You may not use all the counters yourself, but you never know what someone will try  on you.

After you familiarize yourself with the common counters you then need  to start practicing the counters to those counters (what I call ‘re-counters’).  To every counter there is one or more re-counters: sometimes all it takes to prevent an opponent’s counter is a subtle weight shift, and sometimes it takes more drastic measures, including switching to a different submission. Once you understand the counter and re-counter game you are on your way to mastering the kneebar submission.
