JIU JITSU APPROVED REHAB PROVIDER DIRECTORY
•••••••••••••••••••••••••••••••
One of the biggest challenges I hear from Jiu Jitsu athletes is finding a medical professional who actually understands their sport. And honestly, I understand why they can be skeptical. They want someone who understands Jiu Jitsu.

Someone who understands that “just stop training” isn’t always a realistic solution and who can help answer questions like:
* Can I still train?
* What positions should I modify?
* Can I drill?
* When can I start rolling again?
* How do I safely return to competition?

That’s one of the reasons I created a Jiu Jitsu Approved Rehab Provider database.

Since creating Treating the Jiu Jitsu Athlete, I’ve had hundreds of clinicians go through my Jiu Jitsu-specific education. Over the years, I’ve built a growing network of rehab professionals who understand the unique demands of grappling. Now, I’m making it easier for Jiu Jitsu athletes to find YOU.
Clinicians who complete Treating the Jiu Jitsu Athlete and/or the Jiu Jitsu Rehab Masterclass can be added to my Jiu Jitsu Approved provider directory.

So when a grappler is looking for a rehab provider who understands their sport, they have a place to look.

You don’t have to be a black belt to work with Jiu Jitsu athletes.

But you should understand what makes their sport different. That’s what I’m trying to build with Jiu Jitsu Approved: a growing community of clinicians who can provide better, more sport-specific care to grapplers.

If you’ve been considering joining Treating the Jiu Jitsu Athlete, this is one of the additional benefits of becoming part of the community.

Registration is currently open.

Hope to see you in the course

Kimura Arm Break
••••••••••••••••••••••••••
The kimura or the double wrist lock is one of the most powerful submissions in grappling. The joint lock became famous when Masahiko Kimura used it to defeat Helio Gracie in a grappling match.

Most joint locks compromise ligaments that connect joints. What is typically injured from a kimura?

The kimura is a joint lock that primarily attacks the shoulder (glenohumeral joint) by forcing excessive shoulder internal rotation. While the joint capsule, labrum and ligaments are generally the structures that limit this motion they usually aren’t the structures that are severely damaged from a kimura. The most common injury that occurs is a humerus fracture.

Rotational torque from a kimura generally the humerus is the first structure to fail.

Keep in mind that while the catastrophic injuries tend to be humerus fractures that doesn’t mean that you won’t have labrum pathology following a kimura cranked too far.

The easiest way to avoid injury in Jiu Jitsu
••••••••••••••••••••••
TAP to joint locks!

Jiu jitsu GOAT gives words of advice of not letting yourself get injured because you refuse to tap to a joint lock. If Roger, 10x world champion, taps in training… you should not get embarrassed if you tap.

Often athletes do not understand the anatomical consequence of injury. There is no guarantee that an injury will heal 100%, especially if you do not do the proper rehab.

Longitudinal trends for submissions in ADCC between 1998-2026

You can see chokes and attacks to the neck are universally the most consistent method of finishing an opponent.

In the last 28 years there is a fairly consistent rise in leg attacks being used to win, whereas arm attacks are slowly declining.

ADCC 2026 Submission Statistics
•••••••••••••••••••••••
In submission grappling the ultimate goal is to finish with a submission, but which one is the the most common/highest percentage?

Looking at the latest ADCC 2026 which is widely considered the olympics of submission grappling / no gi jiu jitsu. After look at the data these 5 submissions made up 81% of the total finishes.

1️⃣Rear naked choke: 35% (19)
2️⃣Heel hook: 15% (8) 7 inside vs 1 outside
3️⃣Armbar: 11% (6)
4️⃣Ankle lock: 11% (6) 2 Aoki, 1 Mussolini
5️⃣Smother: 9% (5)

Compared to previous ADCCs there was a much higher percentage of finishes via straight ankle locks and smothers and a much lower percentage finishes of guillotines.

These five submissions are consistently the top submissions seen in ADCC. If you want to be a high percentage finisher make sure you are proficient at all of these submission options.

What happened to Kaynan Duarte’s shoulder?
•••••••••••••••••••••
In the ADCC super fight Kaynan Duarte matched up against Yuri C Simões M da Silva . During a scramble Duarte’s post collapsed resulting from an injury and was unable to continue.

This mechanism matches an anterior shoulder dislocation / subluxation. The injury occurs while he had a left arm post maintaining his full bodyweight for the position. His arm slide out and forward, which would out a lot of stress on the anterior shoulder capsule. Explaining the sudden collapse.

Another possibility differential diagnosis would be an AC injury. The mechanism here would be more of a sudden post on an outstretched hand or falling directly on the shoulder. The injury did not occur with the initial reach out but ad it slide forward.

Good thing for Kaynan one of his training partners is orthopedic surgeon M Lucius Pomerantz, MD, FAAOS, DipABLM who specializes in upper extremity injuries. Despite this injury Kaynan still had a great performance at ADCC 2026. I wish him a speedy recovery.
