Beginner’s GuideTo Knee Strikes

You are currently viewing Beginner’s GuideTo Knee Strikes

Though deemed as illegal in many martial art forms, knees are an integral part of Muay Thai and Kickboxing. They don’t just look vicious; they are actually devastating. 

When we talk about using knees in combat, no fighting style even comes close to that of Muay Thai. The always evolving and transforming world of Muay Thai fighting style is based on “Art of Eight Limbs”, which is quite distinctive in nature.

Role of knees in martial arts

The role of knees in this martial art is unparalleled. Just as the art of using an elbow strike is highly sought after in UFC, the art of using knees is equally important.

The impact of the knee strike can knock an opponent out and can cause devastating effects such as breaking their ribs, paralyzing their muscle and even cutting certain parts of the body if used correctly.

We see fighters use them to great effect in combat sports. An exciting example of using knees to the right measure was when Jose Aldo used the double flying knee against Cub Swanson at WEC 41 and scored a knockout within the initial 8 seconds of the bout.

Role of Knee strikes in Muay Thai

There is a lot of information regarding knee strikes on the internet. However, not all of them are correct. Many of the leading portals even carry slightly misleading tutorials which can hinder your progress, to say the least. With that said, there’s no particular way of incorporating a knee style.

Every trainer you train with will have his/her personal philosophy and their way of utilizing the knee would be different.  

Since the basis of the majority of the sports is to score points, greater emphasis is laid on using the kicks and knee techniques with great effectiveness.

What is a Knee Strike?

Though there are more than 8 variations in a knee strike, a primary knee strike usually involves thrusting your knee i.e. knee cap into your opponent’s head or body.

As a beginner, you want to straighten your knees out and without flexing it, notice how you can rotate your knee caps around especially when you stand up. However, when you bend it, your knees tighten up and it becomes hard.

So, when you’re striking with a straight knee, you want to make sure that you bring your heel all the way to your butt so you solidify your knees before you hit your opponent. Your knee cap matters the most, it’s below femur and above tibia. In case of side knee, you use the side of the femur knee, which is the inside part of the knee cap. While doing any of these knee strikes, you must bring your heel all the way back to your butt with your feet pointing towards the ground.

Bad Knee Strike vs Good Knee Strike with Visual Sample

Bad knee demonstration: In the picture below, you’ll see that the additional height achieved in the knee strike makes it highly ineffective. Furthermore, you can see that not enough power has been generated by the knee. Additionally, the knee rises straight up and not at a diagonal angle, which isn’t the most effective method. Even the hips aren’t well turned out and the knee doesn’t seem to penetrate enough which is crucial.

Deploying Incorrect knee technique: A common mistake made by beginners is to hit the opponent with the wrong part of the knee. As explained below, you want to connect with the knee cap. There should be a single contact point which carries all of the force behind the attack. Furthermore, the knee is not placed in up and down position rather than a diagonal position which makes the impact less powerful as it deviates the single-point contact. 

These two images above cover some of the major areas which point out towards the most common mistake. We could’ve divided that into several parts, but the breakdown makes it simple for you to understand the problem. Having said that, let us understand everything that’s right in a knee strike.

Everything that’s right in a knee strike

Look at the pictures above and then look at the image below. The difference between the two knees is so apparent. The hips of the fighter are driven forward whereas his upper body is leaning slightly backward thereby helping him to create more power and momentum going forward with his knee. The upper thigh angle and the lower leg add to the perfect knee strike.

 

How to do a knee strike?

Having said that, let us move towards a stepwise guide on how to do a straight knee strike. Once we get the steps down, we can focus on the variations in-detail:

Take the fighting stance: You don’t want to be in a neutral stance while delivering the knee strike. Make sure you aren’t leaning too forward or backward. Though you have to exert pressure forward, refrain from overdoing it.

Hip Movements: Before you execute the knee strike, your hips should move in the forward direction. Herein, you’re trying to achieve considerable height along with a denting impact on your target.

Arm movements: As you’re about to land your knees, stretch your arms towards one angle to add additional power. For instance, if you’re knee striking with your right leg, you want your arms to stretch out in the same direction. With your right hand farther right and the left one following it across the body.

Don’t just elevate, eliminate: When you’re raising your knees and are about to plant your knees onto your opponent’s head or his ribs, make sure you direct in inwards and not just upwards.

Common mistakes to avoid when doing a knee strike

Not achieving fluid motion: When doing a knee strike, you must be able to use strength, power, and speed of your knee to its maximum capacity. Only when you combine these three elements, will you be able to achieve a fluid motion. Though entry-level practitioners do have a lot of difficulties when it comes to extending the hips, it can be achieved with constant practice.

Moving knee straight up: When using the knee strike, you’re not looking to skim the body of a person. Most of the practitioners often commit this mistake of driving their knees straight up as if their skimming their opponent. Remember, you have to indent your knee strike and penetrate through your opponent. Though it’s traveling in an upward direction, you have to strike towards your opponent’s body aiming to penetrate your knees. Imagine the angle and you’re trying to catch your opponent’s ribs. In such a case, you want to hit the ribs with the knee cap.

Dropping hands low: Most practitioners are often though to drop one hand low to set up a jab post the strike. While it’s not a wrong practice, you should avoid it as much as you can. Instead, you should raise both your hands together whilst you protect your jaws from any kind of attack.

Not bending your knee: A pretty common mistake amongst beginner practitioners is that they do not bend the knee. When you don’t bend the knee, you’re taking away the impact from the strike as you don’t solidify it enough. Moreover, you’re also risking yourself to a serious injury if you get it wrong.

Throwing from too far away: While practicing with a bag, beginners develop a tendency thinking that they can catch their opponent from distance. Since your general reach is slightly more than when you practice using a pad, the reach is underestimated. As a result, when you try to throw the knee from the same distance in a fight, you end up coming short and at the receiving end of a defining blow.
