13: Choong-Jang ground kick, a falling technique?

The ground roundhouse kick in Choong-Jang (move 12) is an annoying move to perform, as well as to find a proper application for. The idea that you should go to the ground just to kick an opponent's groin doesn't hold much water, so usually one of two alternative explanations is proposed:
  • The form assumes you have fallen to the ground and this is you trying to keep back an opponent until you can get up again
  • The movement is a drop takedown
Stephen Kestling
The first one isn't very satisfying, because we begin from a standing position. Nor does it look like any ground kicks found in other arts. (For some examples, see the right image). The second idea is interesting, but I have difficultly coming up with a practical drop throw based on the footwork. In the original set in Woo-Nam, the move preceding the ground kick is a sliding lunge punch, not a flat spearhand thrust, so it seems that moves 11 and 12 were not intended to be a part of the same set.

However I did recently think up an idea similar to the first option: what if it's a falling technique? The difference being that you can use the footwork prescribed in the form to get into the ground kick position. In fact, the collapse down onto one knee looks like the first part of an Aikido falling technique an instructor once showed me, in response to a strong shove that will take you to the ground. After searching online I found an example, shown in the gif below.

The backwards roll is the advanced version. What I want to call attention to is the first part of the technique, where the aikidoka cross-steps the back leg and collapses onto his back knee/hip. Instead of doing a roll, from here you can use both palms to hit the floor, bracing you. As this point, you have the exact setup for the roundhouse kick in Choong-Jang/Woo-Nam.

My point is that the set is probably meant to be applied against someone pushing you to the ground, not that you begin on the ground. Is it a set I envision myself ever using? Not really, but I find it a more reasonable explanation than the two provided above. After you brace yourself, kick your opponent with the ball of the foot roundhouse kick.

The rest of the set

What about the ground punch directly afterwards? Punching the opponent's groin? Actually, I prefer Paul O'Leary's explanation (which he details in this post) that it's a takedown. The back hand traps the opponent's instep while the "punch" pushes out on their knee, taking them to the ground. From here, still controlling your opponent's leg, you use the next two movements in the form -- clockwise step into side elbow strike followed by clockwise turn into closed fist guarding block -- to flip the opponent onto their stomach and possibly get a leg lock.

12: Do-San (and Taebaek) 360-degree spin

A while ago I posted some applications for the 360-degree spin in Do-San. Looking back, I realized that I provided no application with the guarding block beforehand. So in this post I'm going to provide two: one for Do-San and one for a variant of the set used in the kukki-taekwondo form Taebaek. The first application, an overhook and torso push, is shown in the gif below.

Source: WeAreGoodCompany
  • Use the knifehand guarding block simply as a block, deflecting a punch outward while stepping in. (In the gif, you can also see the chamber used as a block)
  • Overhook the opponent's arm with the supporting arm of the supported spearhand thrust
  • Now that you have the overhook, use the spearhand to push onto the opponent's torso, or perhaps their face.
  • Use the 360-degree spin while pushing on the opponent's torso/face to take them to the ground, pulling with the left hand (backfist)
Most schools practice a downward "release motion" in the set (although neither the 1965 or 1985 versions of the form instruct this). This can be used to aggressively push down the opponent before spinning. The 1985 version of the set instructs a turning of the palm. This can be used if you are pressing on your opponent's face to turn it downwards, causing them to further lose balance. In the gif the defender steps behind the opponent to do the throw. This is ideal, but even if you can't step behind you can try using the whole 360-degree spin as the takedown.

A similar technique can be seen in the gif by Dan Djurdjevic below. Here the pull back (guarding block chamber) is used to pull the opponent's arm. As the opponent resists, move back in the forward direction (guarding block), and then get the overhook and torso push.

Source: Dan Djurdjevic
The overhook and torso push is the first deeper application I would teach to a student. It's simple to remember and to perform.

Taebaek version

The kukki-taekwondo form Taebaek has this set, and performs it almost like we do, but they add in a strange motion: pulling the spearhand behind the back before you turn. I don't practice this form, but something it might be is encircling the opponent's head, in order to throw them as you spin. In this case the intended application would be a head-and-arm throw.
Sources: TaekwonWoo, James St. Pierre
  • Use the knifehand guarding block (called "double knifehand block") as a grappling position. Back palm gets a collar tie, front palm gribs their arm.
  • Step through (spearhand thrust) and then encircle opponent's head while pivoting (pulling the arm behind the back)
  • Finally, use the spin into backfist as a hip throw
This hip throw application also works for Do-San, as the downward release motion some clubs practice can also be used to wrap the head.

Koryo complete interpretation

After taking a look at the Kukkiwon forms I found Koryo interesting enough to learn and analyze. I don't have the images to do a full visual treatment of the form, and the Kukkiwon forms aren't the subject of this blog anyway, but I did write up applications so I thought I'd share the text here. Maybe someone else can come across this and test them and take pictures. I'd be interested to hear what kukki-taekwondoin think.

The Kukkiwon forms are looked down upon in some martial arts circles as being simple, for performance only, or having no practical applications. In my overview I didn't find this to be the case; I think that the poomsae have a lot in them that taekwondoin aren't seeing, similar to the ITF forms. One interesting thing I found about Koryo is that it seems to contain a number of "what if?" scenarios. These also occur in ITF forms, but less commonly from what I've found.

Koryo Analysis

Ready position as a “fence” (hands up to protect yourself)

App 1: Against a haymaker
John Titchen Practical Karate
  • Block a haymaker by stepping in and sticking out your parallel arm (double knifehand block chamber)
  • Overhook opponent’s arm (back arm) while pushing out on their neck (front forearm) for control. Make sure you are 90-degrees from your opponent.
  • Try to shift opponent's weight onto their far leg and kick in their inside knee with the low side kick. If successful, they should collapse away from you, so follow up with the middle side kick to their ribs or head.
  • You may follow up with knifehand strike and punch as additional strikes if necessary
      What if #1: You block the haymaker too far away to overhook
  • When you block, you are in the knifehand strike position
  • Grab and pull in the opponent’s arm while punching their solar plexus or jaw.
  • Block their other arm if necessary. Now grab and pull them back (shifting weight into back stance) and hammerfist the side of their head (inward block).     
  • Use the 90-degree turn into low knifehand block as a throw
App 3: Against a straight punch
  • Deflect a straight punch inward (low block chamber).
  • As your opponent retracts, stick to their arm by digging the low knifehand block into their elbow. This both pushes it down and makes it easier to grab.
  • Strike their neck with the arc hand strike as you pull in their arm. Although the form is one-two, try making the low block and back hand arc hand strike semi-simultaneous.
      What if #2.1: Opponent parries your arc hand inward with their free hand
  • Still pulling in their other arm, front kick to push them backwards
  • Use the second low knifehand block to crank their elbow inwards, causing them to bend over backwards.
  • Use the second arc hand strike as more of a palm strike to the side of their jaw, causing them to bend over backwards even more. Then guide them to the ground.
  • This set is repeated on the other side for symmetry, which is why you do the arc hand strike three times in the form.

      What if #2.2: Opponent parries your arc hand outward
  • Front kick, aiming for the groin, then use the retraction to trip opponent’s parallel leg. Land forward.
  •  Slide arc hand down to opponent’s lower back. Push in their lower back while you push their upper torso out and down to throw ("Knee break").
"Knee break" as a throw.
Danish Taekwondo Demonstration Team
            What if #3.1: Opponent tries to pull you to the ground with them
        • Step forward onto their face (footwork)
        • Turn 180-degrees and squeeze their arms (opening block chamber), then use the block-proper to break their grip.
        • Disengage
            What if #3.2: Opponent succeeds in pulling you down on top of them
        • Against an untrained opponent, you are in full mount. Not a scary position.
        • Get a collar choke (second inner-forearm opening block). Grab opponent’s collars cross-armed (chamber) and pull in while leaning your weight forward.
Collar Choke. Gracie Breakdown.
App 8: Against a double grab, or similar situation
  • Reach palm behind opponent (outward knifehand block) and punch head while holding it to prevent them from riding the blow (target punch)
  • Still holding their head, attack both legs. Cross step onto their instep to root them in place (alternatively, perform a oblique kick/shovel kick to one leg)  and side kick their other leg
  • Land turning 180-degrees and push down their head to throw.
Sources: Majest, Craig Gray, Richard Conceicao
App 9: Against a front bear hug
  • Strike opponent’s groin with back palm while sliding up front palm to create space between you and opponent.
  • Grab and lift up their leg to the side (reaction hand) while pushing their torso out with the low block
  • Step forward behind opponent’s legs. Grab the back of their shirt (reaction hand) and their face (palm set up). Use the palm pressing block to throw the opponent by simultaneously pulling in the back of their shirt while pressing their face down.
  • If the opponent doesn’t fall, then follow with the elbow strike to the side of their jaw. This also turns their head away from you, so you should be able to push them down over your hips (riding stance) from this position
Sources: Majest, Craig Gray
      What if #4: Can’t lift leg
    Encyclopedia of Taekwon-Do, Vol 5
    • Transition into the elbow strike after the low block, pushing back opponent so you have more space. You have also turned 90-degrees to your opponent.
    • Push off one arm (palms shooting upwards).
    • Wrap your near arm around the opponent’s other arm for a maki hiji lock, bending their elbow inward with your parallel arm. In the form this is in slow motion to represent that you are manipulating the opponent’s body, not that you would perform it in slow motion. The closed-fist hand is the “active” hand getting the lock.
    • Use the 180-degree turn into the knifehand strike to both pop their elbow and throw them.
App 11: Against a punch
  • There are multiple ways to interpret this last set. I've tried to create a drill which incorporates all the moments, minus the symmetry.
  • Down parry an incoming punch (knifehand strike chamber, back hand), then counter with the knifehand strike.
  • If the opponent parries with their second arm, push down and pass their first arm (the one that punched you) with the low knifehand block, putting you outside the opponent's arms.
  • Grab and pull as you inward strike the side/back of the opponent's neck
  • If the opponent dodges, the inward strike becomes an inward block to the opponent's free arm. Then press down into the elbow of the arm you do have a hold of (low knifehand block)
  • As the opponent recovers from being forced down, step forward and dig upwards into their throat with the arc hand strike.
  • If you strike with your right, the simultaneous pull of the opponent's right arm will force the opponent to turn counter-clockwise slightly. Use the  counter-clockwise 180-degree turn back into the "pushing hands" ready position as a head crank.  (The position of the palms suggests you are holding the opponent’s head). Then throw them to the ground via the head.

Addendum 12-9-2017: More about the double side kick

What if the opponent's weight isn't on their far leg so it just gets knocked back? You can still use the second side kick, but this time as an uchi mata (inner-thigh lift) throw, as shown in the gif below.

Source: monsterprone

This is especially useful if you are using the double knifehand block to grip the opponent in a different way. Purists may not like how the side kicks are performed at different angles, but it is a practical application.

I also recently came across a minor detail about the first kick in this video:
Note that you kick yourself into the turn, like a soccer kick. You don't turn your body, and then kick.
Uh, that sounds like a low roundhouse kick to me. And if it's true then the application for this set (low roundhouse kick followed by middle side kick) would to kick in the back of the opponent's front leg after the guarding block (see above), then perform the "middle" side kick to the back of their other leg, taking their balance. Finally, use landing into front stance knifehand strike either as a throw (pushing back the opponent's torso/neck, using the back hand punch as an extra push if necessary) or as a strike to the side of the neck, depending on how exactly your opponent reacts to the leg kick.

11: Koryo low section hammerfist

Sources: Majest, Ebrahim Saadati
Before I take another break from the blog, I wanted to look at a set from the kukki-taekwondo form Koryo. Near the end of the form is a circular, low section hammerfist strike, performed in slow motion. It seems there is no consensus -- or even many ideas -- on what the movement is for. After playing around with it though, I found something which might be close to the original intent of the set.

We can apply the movement against some sort of double grab (like an attempted front bear hug), beginning with the preceding move, the elbow strike.
  • Turn 90-degrees as you step forward and elbow strike your opponent, creating space. 
  • Push off the opponent's left arm with both of your palms (arms shooting upwards).
  • Circle your left arm around your opponent's right elbow, trapping their arm and bending it inwards.
  • Lift up your left arm (chamber for knifehand strike) to wind back your opponent's body. You can pop their elbow by extending your arm (knifehand strike) and attempt to throw them by turning 180-degrees as you do in the form.
Left: App for movements 25b-26.
Middle: The lock from the Encyclopedia of Taekwon-Do
Right: Jon Jones using the lock in UFC 172.
The left hand is closed because it is the active hand, and the movement is performed in slow motion to represent that it is manipulating the opponent's body (not that you would actually perform the movement in slow motion), as opposed to being a hard block or strike.

This lock is known as maki hiji in jujitsu, and is present in Gen. Choi's Encyclopedia of Taekwon-Do. It gained some notoriety a few years back when Jon Jones used it in the UFC. You can see a Jujitsu player demonstrating the lock in the gif below, as well as using the turn as a takedown. The difference is that the Jujitsu player uses a two-step tenkan turn, whereas in Koryo it seems that you only move one leg before turning.

Source: Submissions 101
The defense to this lock is basically to pull in the opponent before they can get a solid crank, as explained by Stephen Kestling here.

Credit to Orjan Nilsen for suggesting a front bear hug defense for the set, and to Peter Jones for the idea that a circular low section block could be used to make a maki hiji lock.

10: Hwa-Rang chicken wing lock

Hwa-Rang is the oldest ITF form, which just might make it the first Taekwondo form ever created. It is also one of two forms created by Nam Tae Hi [1], the other being Choong-Moo. Based on my analysis, Hwa-Rang is mostly about limb control, whereas Choong-Moo is mostly about throws.

One simple example of limb control is moves 15-17, which we can use to create a chicken wing lock (also called a hammerlock [2]). This lock is commonly used by security and law enforcement. The set is:
  • Knifehand guarding block
  • Supported spearhand thrust
  • Turn 180-degrees into knifehand guarding block
  • (Optional) back leg roundhouse kick
The Technique

Let's start with something manageable: an attempted lapel grab.
Source: Springfield BJJ Network
  • Raise your back arm to ward off the attack (guarding block chamber)
  • Circle low so that your back hand is blocking your opponent's wrist, and grip under their tricep with your front palm (knifehand guarding block). This is the set up for an arm drag.
  • Pull the opponent's tricep towards your body (supporting hand) while you force their forearm back with the back of your right forearm (spearhand thrust). This both bends your opponent's elbow and creates the initial shoulder lock. Another example by Jeremy Pollack is below
Supported spearhand thrust application. Source: Gun Carrier
  • Turn 180-degrees and use your right hand (the back hand of the second guarding block) to press down on your opponent's elbow, putting them into a chicken wing lock.
  • (Optional) kick in the back of their legs with the roundhouse kick, taking them to the ground.
The most important tip for maintaining this lock is to put pressure on their elbow, not their triceps or shoulder, as the opponent can resist the latter fairly easily. Although kicking in the back of the legs is a suitable finish, another takedown you can do is just circle counter-clockwise while pressing downwards on the opponent's shoulder.

Instead of using the supporting hand to grip the inside of the opponent's triceps, you might grip the outside of their elbow or perhaps their shoulder, though the latter requires more brute strength.

The roundhouse kick can also be used as a contigency leg sweep in case you fail to apply the lock properly and the opponent slips free.

Entering with the guarding block

On application of the knifehand block I often see is striking the side of the opponent's neck in close range. Personally I find this difficult to perform with power (why not just punch or do a normal knifehand strike?), but if you step forward into the movement it can work as a "push", using your forearm and body weight to press the opponent backwards. This is especially useful if your opponent is already leaning back, perhaps in response to a punch you've thrown.

Most of the sets in Hwa-Rang can be interpreted as a response to your right hand punch being parried or grabbed, so let's use that interpretation here as well. Open with the first move of the form -- palm pushing block -- to push down an opponent's guard (or perhaps parry their right) and follow up with the punch. If the opponent parries while leaning back, then we step in and execute the guarding block to their neck. Although this is a "strike" because we are hitting the neck, the main purpose is to keep up pressure on the opponent and create an opportunity to perform the lock. The back hand of the guarding block circles up and then down, as in the chamber, going over the opponent's arm. We may then attempt the chicken wing lock.
Sources: Samir Seif, PracticalKataBunkai, AikiProductions
You may need to clear the opponent's parrying arm before moving in. The three-step application of the guarding block shown below can be used for this. Knock away the opponent's arm with your front hand (chamber), then hold it down with your back hand while you strike the side of their neck (block-proper). I find this three-step approach slow to use, but knocking the opponent's arm down in this way does place you in a better position to attempt the lock.
Source: Richard Conceicao
In this case I'd recommend using the back hand to grab and pull -- turning the movement into a single knifehand block -- as this increases the power of the strike.

[1] Nam Tae Hi's student Han Cha Kyo made Ul-Ji, so sometimes Ul-Ji is credited to him as well. These three forms were made almost a decade before the majority of the ITF forms; they may have been meant to be a stand-alone self-defense system.

[2] "Hammerlock" can also refer to a similar, two-handed lock where you pull the opponent's elbow in towards your hip while forcing their wrist up towards the back of their neck.

9: Po-Eun leg lift

Source (right image): MEMAG
The final two moves of Po-Eun are
  • Cross step into X-stance low front block, with the opposite palm hitting the the side of the fist
  • Step out in the same direction into riding stance low ridgehand guarding block
Unlike the knifehand low front block in Kwang-Gae, there are no instructions for the movement to be circular. Personally I prefer grappling interpretations for Po-Eun; the preceding set works well as a headlock defense, for example. However, the low front block is usually explained as blocking a front kick, so I think it's worth first exploring that application.

Front kick defense

First question: can the movement be practically applied against a front kick? Yes, actually, but not in the way you might think.

You never want to block a front kick straight on. Rather, you want to get off the line of fire and deflect the kick. One simple way to do this is by twisting your body. Take a look at the gif from one of Dan Djurdjevic's older videos.
Source: Dan Djurdjevic
Notice how after twisting, he takes a cross step in towards his opponent. He uses his front arm not as a hard block but rather as a deflection. So the X-stance low front block does work against a front kick, but the trick is that you should be facing sideways from your opponent. We can use the opposite hand (the palm hitting the side of the fist) to catch the leg after deflecting.

What's neat about this defense is that it works no matter what leg the opponent kicks with, and we can still utilize the ending move of Po-Eun as a takedown. If you catch the leg from outside, then you just use your forearm to press down your opponent's torso while lifting their leg.

But what if you catch the leg from inside? This is where the grappling interpretation comes in.

Leg lift with inside trip

Suppose we are not facing a front kick but are rather in a grappling situation. The low front block can be used as a two-handed leg pick, using the cross step to get close. You then step through the opponent's legs into the riding stance, setting up an inside trip, and lift their leg. The chamber for the guarding block -- raising both arms back -- comprises the actual throw, but as the opponent falls your arms naturally go into the low ridgehand guarding block position.
Source: MEMAG
If you catch an opponent's front kick from the inside, you can use this throw as well.

It's worth noting that the source video shows two counters to this throw, one of which is just a strike to the thrower's head. Using both hands to grab a leg leaves your head exposed, so think carefully about when it's proper to apply this technique. You might apply the previous two moves in the form as strikes: an elbow strike to the throat followed by a low hammerfist to the groin. This will distract your opponent and allow you to go for the leg lift. As before, you should be facing your opponent more-or-less sideways.

8: Joong-Gun and Ko-Dang revisited

In this blog I've provided a comprehensive analysis of three ITF forms: Joong-Gun, Ko-Dang, and Kwang-Gae. Since then, I've gone back through the sets and made little changes based on a better general understanding of applications. In this post I want to revisit two sets: the roundhouse kick defense in Joong-Gun (moves 20-22/23-25) and the guarding block followed by double block in Ko-Dang (moves 3-4/7-8).

Joong-Gun roundhouse kick defense

Rather than use the double forearm block itself as the kick defense, we use the set-up as the defense, stepping forward and away from the kick while we prepare to use our back arm to either under or overhook the opponent's leg[1]. We use the front arm as a strike, such as a backfist or uppercut to the face, or simply just a ram with our forearm, knocking the opponent off-balance.

The footwork for the set is to semi-circle forward into front stance for the double forearm block, pull the front foot back in, then step forward into back stance as we punch with our front hand. Use this footwork to circle around and sweep the opponent's standing leg. If they don't fall, we then use the "punch" as a push, knocking them to the ground.
Sources: Southern Minnesota Martial ArtsCurransKarate, Arirang Culture
So if the double forearm block (with chamber) and the punch comprise the defense, then what is the point of the third move in the set, the side kick? It could be an alternative takedown: kicking in the opponent's standing knee in case we catch the roundhouse too far to sweep. Another possibility is that it's to help escape an opponent who attempts to pull you to the ground with them. Side kick the groin or torso of the downed opponent until they let go of you.

Ko-Dang tackle guard and arm break

Source: Code Red Defense
Stepping backwards 45-degrees into guarding block is a good, basic tackle defense. But I was mystified by the following move, where we transition into a simultaneous front hand inner-forearm block, back hand low block while maintaining our stance. In retrospect, the application is pretty simple. Your opponent may still be able to grab your front leg or waist as you guard, but because you are pushing their head back their arms will have to be extended. Thus, you simply use the inner-forearm block to hyper-extend one of their arms, as shown by kukki-taekwondo master Dong-Hee Lee[2] below.
Source: Dong-Hee Lee
The simultaneous back hand low block may be used to break the opponent's other grip, traveling in between their two arms.

Another option is to simply break the arm you already have a hold of after the guard (the fact that you use closed fists in the form indicates that you are grabbing). Use the low block to pronate the opponent's arm, so that their elbow faces outward, and the inner-forearm block to strike the outside of the elbow. The positioning is a little more awkward, but a quick hit could end the fight.
Sources: TKDdragon, MEMAG

As I've stated before, there are other ways to interpret these forms, but I think it's neat that you can find a thematic framework to them. I'm considering writing a comprehensive analysis of the Original Koryo; it's not an ITF form but I was impressed with it enough to learn the movements, and it's easy proof that the Kukkiwon forms (at least the older ones) have applications as well.

[1] The subsequent counter given in the form assumes an overhook. I've noticed that a lot of traditional martial artists teach to underhook a roundhouse kick, but Muay Thai fighters overhook. This may be because an underhooked roundhouse is easier to escape via spinning out, i.e. continuing to turn in the direction of the kick.

[2] I have to thank White Dragon Dojo for the introduction to Dong-Hee Lee, who has various youtube videos showing applications (mostly striking) to kukki-taekwondo poomsae.
