You are probably missing kuzushi (balance breaking) and/or atemi (strikes). Both serve the same purpose: to distract your opponent so that they worry about something else rather than their wrist. Then, applying a wrist lock becomes easy (read: easier). The ninth technique of the goshin-no-kata shows just what I mean: you have a lapel grab which is ...

Primary and secondary grappling skills Wristlocks and most other standing joint locks are almost always secondary grappling skills: one must already be able to dominate using basic gross-movement wrestling skills like pummeling, grip/hand fighting, foot-sweeps, hip throws, body locks, and so on. Part of the problem is strength: standing wristlocks and ...

Nearly all forms of aikido are predicated on avoiding any possibility of pressure-testing their skills against resisting opponents in free-sparring or competitive environments. Nearly all practitioners stick to demonstration and practice with cooperative partners. From this it naturally follows that few aikidoka will be caught on camera trying to apply their ...

I assume you are working on the arm bar known in judo as juji gatame. The principle in this technique is the use of a class 2 lever to hyperextend the opponent's elbow joint. Resistance is in the middle, at the opponent's elbow joint. Force is applied by pulling down at the wrist and raising the hips. The fulcrum should be one of your legs; this makes any ...

If there's a lack of progress during ground work in a judo match, the referee will stand the competitors up. This is intended to encourage action, rapid attack, and prevent stalemate positions.

Teaching children in Judo for 13 years now and having made an instructor's license, I will try to pin it down to some principles (as concrete lessons may be established, but are dependent on the group). General principles (all techniques/ages) These principles do not only apply to children (or ukemi), but are more essential to be held in mind and used in ...

From my own experience, a match between judo/aikido starts at a distance doing Aikido and as soon as the distance closes, switching to judo. I have no link to videos as I never bothered filming any. However, this is what Tomiki found when he started to introduce Judo randori style play into Aikido: his students (who all knew some Judo) would automatically ...

I prevent testicle crushage while armbarring my partners and opponents by: Pulling the arm further towards my head, so their elbow is across my pelvis and not my crotch Squeezing my knees tighter on their upper arm Wearing underwear (or lack thereof) that provides freedom of movement, so that they can move out of the way of an elbow mid-attack Not giving a ...

I've learned both methods in judo, BJJ, and karate. Tucking the bottom leg makes for smoother rolls and stand-ups after the fall, but makes little sense if one cannot roll and is just trying to best take the impact. It is also suboptimal for rolling if one's opponent is still latched on. Keeping the bottom leg mostly straight is good for stopping the ...

First things first, I think you should see a doctor that could give you a "go". A specialist could tell you if he thinks it would be safe for your knee if you restarted doing martial arts. If the doctor says no, you're putting yourself at risk if you restart. Let's face it, even if you feel your health is deteriorating, it is much better than with a ...

If you are 75 kg, then you should not have a problem throwing an opponent who is 102 kg with a basic hip throw. The major hip throw (ogoshi) is the first hip throw in the judo curriculum. It's simplest to start with throwing ogoshi slowly because ogoshi has the nice property that you can stop mid-throw. It's easiest to understand the mechanics while ...

I've been training Bjj since 1998. I always learned to squeeze my knees to prevent this pain on testicles. This is the most common way to avoid this kind of injury. But this year, when I was visiting the academy of the Master Sylvio Behring, he taught me a different approach for the arm lock (arm bar). Squeeze your knees early. He told me to close my knees ...

I see no problem in training on the beach as long as the sand is dry, clean (no rubbish), relatively plain (no bumpiness) and fine (it adapts better to the impact, same reason why it should be dry). It might be slightly harder than a mat, but it's far from dangerous. It might even improve ukemi by 'punishing' bad posture or lack of tension. Modern mats are ...

On the physical side: Knee ligament replacement surgeries are pretty good these days. You should see a doctor to see if that is an option. (You might want it anyway, even if you don't train hard, because you want to make sure you're not suffering meniscus wear as well...). The second person you want to see is a sports medicine specialist. They can let ...

Yes, the above technique would be a pin in competition judo. A pin in competition judo does not need to be a standard pin; it needs to meet the definition of a pin under the referee rules. This is good especially because judo people can get very nitpicky about what exactly constitutes a particular pin [more on that later]. If your opponent taps at any time ...

I am going to assume we are talking about the cross body arm lock (juji gatame, in judo). It is possible to escape before an opponent sets in a joint lock tightly. This basically involves maneuvering your elbow out of your opponent's legs. It's easiest to do this if you can still move your body around effectively. It is not possible if you wait too long. ...

According to forensic science it is pressure applied to the carotids and not the veins that causes loss of consciousness, although pressure on the veins leaves specific signs of strangulation when they bust, but are not a cause of death or unconsciousness. (pg. 297, 14.2 Strangulation, see section #2 re: carotid compression). Although the deeper carotid ...

There was a machine at a gym I used to go that was inadvertently an armbar exerciser. It started you out on your side, with your body in a "crunch" position, and you moved to straighten out your back, just using your core muscles, resisting against a weight that wanted to keep you crunched up. Basically, this is the armbar movement, where you are crunched in ...

Whatever you do in Aikido, the simple rule of thumb applies: never play fair! If your and your opponent's hands are similarly strong and you're performing your lock single-handed, than you have a very slight chance to prevail. In order to achieve the goal of your lock you have to: use both hands against the one of the opponent use your legs and body ...

I also train in TKD and though we don't train for grappling (locks, chokes, etc.) very often, we are told that against a stronger opponent, you may need to do something else to weaken their grip. (As Sardathrion explains in his answer). The weapon of choice is a kick or strike to the groin! You may find that there is a small but vital aspect of the lock ...

What I've picked up over the years about how blood chokes actually work - and I could be wrong - is this: There's a nerve in the neck called the Vagus nerve. One of its many functions is to sense blood pressure of the arteries in the neck. When you compress those arteries, it will cause blood pressure to increase rapidly. The Vagus nerve senses it and ...

For a judo perspective on falling technique (ukemi), the best place to start is the formal throwing techniques (nage-no-kata), where the most emphasis is placed on falling details. For forward rolling falls (zempo kaiten), there are two basic possibilities: You cannot roll and stand up, as in the nage-no-kata fall for tsurikomi goshi. You may be ...

Its never to late to start martial arts as a hobby. If you should have higher hopes to do that on a professional level, it depends a lot on which martial arts you want to do. There are several cases in mixed martial arts where people became professionals, even though they started relatively late, even some of them with no prior martial arts expierence. ...

I'm rather short, 5'7" and the biggest issue that people have working with me is because of my low center of gravity, I'm very difficult to be thrown but I'm in a good position to throw people. So you'll find that you have to make changes to your game in order to compensate for the height difference. I'd also recommend that anyone you train with knows ...

Well, technically 'Guruma' implies a 'rotation', so like in Ashi Guruma in Osoto Guruma you're not just reaping two legs, you're leading your opponent towards a rotating movement around your leg, just like Ashi Guruma. Wheel just indicates the rotation this technique implies. The difference between Osoto Guruma and Osoto Gari, if you will is similar to the ...

I've trained in many martial arts schools. There have always been one or two individuals that didn't know their own strength or who simply had some kind of mental issue that caused them to scare everyone else in the class who had the misfortune of partnering up with them. And I'm not even talking about sparring. It could be a nice, smooth, flowing, ...

I study in the Bujinkan, and the instructor I've been working with and I worked through all three "scrolls" of the Gyokko-ryu, and one thing about all the locks and throws there is that while we teach the locks in isolation in order to get an understanding of them, in the kata you always do something to the person before applying the lock (usually some sort ...

The best option would be to ask your instructor to watch what you do with both the opponents you mention in your post. He will be able to check that you're doing the technique correctly and if you're doing it differently for the two opponents. Alternatively (and if you're allowed to) have someone video you performing the technique on both opponents and see ...

It can be very hard to impossible to willingly off-balance an (maybe sub-conciously) uncooperative, stronger opponent, i.e. to have enough kuzushi. That is where Judo (in the very sense of the expression) begins. And as Judo is Jujitsu specialized on throwing (among other things), I will answer purely in this context. I personally had the experience with a ...

Though they come from similar bases, Aikido and Judo are designed for entirely different purposes. Judo was explicitly designed as a competitive grappling sport, grappling against other judo practitioners primarily within a dojo or competition hall, and it's techniques and training have expanded to fill this role. Aikido was designed to provide a mechanism ...
