Quick Definition
A reverse armbar is an arm lock that hyperextends the elbow from the opposite side of a standard armbar, using the attacker’s chest or forearm as the fulcrum instead of the hips.
What is a reverse armbar?
A reverse armbar attacks the same joint as a regular armbar, the elbow, but flips the orientation. In a standard armbar, the attacker lies perpendicular to the opponent and levers the arm over the hips. The reverse version keeps the attacker on the opposite side of the trapped arm and presses the elbow against the body or a grip, bending it the way it is not meant to go.
The name describes a family of techniques rather than one fixed move. The most common form is the inverted armbar, known in Judo as ude-gatame, or “arm hold.” It can appear from bottom positions, such as the closed or butterfly guard, and from top positions like side control and mount. What ties the variations together is direction: the elbow gets loaded from a reversed angle, which is why grapplers often catch it in scrambles when an opponent reaches or posts an arm at an unexpected moment.
Because it does not need a gi to work, the reverse armbar shows up in both gi and no-gi grappling, and it carries over into MMA, where the same elbow mechanics apply.
How the reverse armbar works
A straight arm lock needs three things: control of the wrist end of the lever, control of the shoulder end, and pressure on the elbow in between. The reverse armbar isolates the arm by trapping the wrist with the head and shoulder so the opponent cannot pull it back, then exposes the elbow for the finish.
Pressure usually comes from a figure-four or Gable grip behind the elbow, though some variations drive with the forearm or even the knees. The attacker’s torso is the fulcrum, which is the part that separates this from a textbook armbar. According to BJJ instructional site Digitsu, the lock stresses the medial side of the elbow and the ulnar collateral ligament, so a slow tap is the difference between a sore arm and a torn ligament or dislocated joint.
The trade-off is control. A standard armbar from mount pins the opponent first, then finishes. The reverse armbar is more opportunistic, which is why coaches treat it as a fast attack to hit the moment the opening appears rather than a position to settle into.
Reverse armbar vs standard armbar
Most people searching this term already know the regular armbar and want to know how the reverse one differs. The short answer is body position and the direction of pressure. Here is the side-by-side.
| Feature | Standard armbar (juji-gatame) | Reverse armbar (inverted / ude-gatame) |
| Attacker position | Perpendicular, on their back, legs over opponent | On the opposite side of the trapped arm, often upright |
| Fulcrum | Hips and thighs | Chest, torso, forearm, or a grip |
| Common entries | Mount, closed guard, back control | Scrambles, guard, side control, failed submissions |
| Primary use | High-percentage primary finish | Opportunistic or transitional attack |
| Joint stress | Elbow hyperextension over the hips | Elbow hyperextension against the body, medial side |
The armbar family as a whole is among the most finished submissions in the sport; grappling retailer BJJ Sportswear notes the standard armbar consistently ranks among the top three submission finishes in IBJJF competition and is the third most common finish in the UFC. The reverse version is rarer and tends to surprise opponents who are defending the orthodox lock.
Other names and related variations
Few techniques carry as many aliases as this one, which is a big reason people get confused. The same basic move is sold under a handful of labels depending on the coach and the era.
| Name | Notes |
| Inverted armbar | The most common modern term; body sits opposite the arm |
| Ude-gatame | The Judo name, meaning “arm hold” |
| Arm crush / razor lock | Older grappling slang for the same elbow press |
| Cutting armbar / pressing armbar | Terms favored on guard-based versions |
| Violin armlock | A nickname from the arm-cradling finishing posture |
One label causes real trouble: the Fujiwara armbar. Named after Japanese catch wrestler Yoshiaki Fujiwara and carried into MMA by catch-wrestling figures such as Erik Paulson and Josh Barnett, it is a top-pressure elbow lock that some sources also call a reverse armbar. It is closely related but applied from a different top position, so the two terms are not perfectly interchangeable. A separate usage, the far-side armbar from mount or side control, attacks the opposite arm by turning the hips the other way, and gets called a reverse armbar as well.
Where it shows up in grappling and MMA
The reverse armbar has a reputation as an underused or “forgotten” submission, partly because it ignores the usual position-before-submission logic. It rewards grapplers who can spot a brief opening rather than build a dominant pin first.
Marcelo Garcia, a four-time ADCC and five-time world champion, is the name most associated with making the inverted armbar respectable at the elite level, often using it as a threat to open up sweeps and back takes rather than as a pure finish. Modern no-gi standouts like Gordon Ryan use it the same way, as a bridge inside a chain of attacks off the Kimura, omoplata, or a defended standard armbar.
In MMA, the technique is uncommon but legal, since it is a recognized elbow lock rather than a banned twisting or small-joint attack. It tends to surface in transitions and scrambles, where an opponent posts a hand or reaches across and leaves the elbow hanging in exactly the wrong spot.
Frequently Asked Questions
Is a reverse armbar the same as an inverted armbar?
In most usage, yes. Inverted armbar is the more precise modern term, and reverse armbar is the everyday name for the same elbow lock applied from the opposite side.
Is the reverse armbar legal in MMA and BJJ?
Yes. It hyperextends the elbow, a legal joint, and is allowed in MMA and at all belt levels in most BJJ rule sets, unlike certain leg locks or twisting attacks.
Is a reverse armbar the same as a Fujiwara armbar?
Not exactly. The Fujiwara armbar is a related top-pressure elbow lock from catch wrestling that some people call a reverse armbar, but it is applied from a different position.
Why is the reverse armbar considered rare?
It is opportunistic by nature and lacks a safe holding position, so it appears in scrambles and transitions rather than from a settled pin, which keeps it off most beginners’ radar.
What does the reverse armbar injure?
Like any straight arm lock, it targets the elbow, stressing the medial side and the ulnar collateral ligament. Held past the tap, it can tear ligaments or dislocate the joint.
