How the Reverse Shrimp Gets You Out of the Armbar from Mount

The armbar from mount is one of the most common submissions in jiu jitsu at every level. Studies on black belt matches at the highest level tournaments have consistently ranked it among the top two most common submission finishes. That is not because it is flashy. It is because it works, and it works against people who know it is coming.

If you train jiu jitsu long enough, you will get caught in this position. Your opponent is on top of you in mount, they have isolated your arm, and they are starting to transition to the finish. At that moment, most people do one of two things. They panic and start muscling against the submission, which accelerates the tap. Or they freeze and wait for the submission to finish.

There is a third option. There is a window, a specific moment just before the finish becomes unavoidable, where one movement changes the entire situation. That movement is the reverse shrimp.

The video below covers how to do the reverse shrimp and how to apply it in this specific situation. The written breakdown after it explains why the movement works and what you need to understand to use it consistently.

Why Most Grapplers Have Never Drilled This Movement

The regular shrimp, which most people know as the hip escape, is one of the foundational movements in jiu jitsu. It shows up in warmups at almost every gym. Students drill it from their first week on the mat.

The reverse shrimp is its less practiced counterpart. It moves in the opposite direction and it solves a different set of problems, but it does not get the same consistent drilling attention that the regular shrimp does. As a result, most grapplers know it exists but cannot execute it reliably when it matters.

This is worth knowing because a movement you have not drilled regularly will not show up when you need it in a live roll. Your body defaults to what it has practiced. If the reverse shrimp is not in your warmup rotation and not something you have drilled deliberately, it will not be available to you when you are under pressure.

That gap between knowing about a technique and being able to use it is one of the more honest things jiu jitsu reveals about how people learn. Awareness is not the same as preparation.

What the Reverse Shrimp Actually Does to the Armbar Transition

To understand why the reverse shrimp works here, it helps to understand what your opponent is trying to do during the armbar transition from mount.

When someone transitions to an armbar from mount, they are moving their weight toward your head and angling their body across yours to isolate your arm. That movement is directional. They are committing their weight in a specific direction to create the leverage they need for the submission.

The reverse shrimp works by moving with that direction rather than against it. Instead of trying to pull your arm back, which fights the leverage your opponent is creating, the reverse shrimp moves your body in the same direction their weight is traveling. When you do that correctly, you remove the base they are building toward and their transition collapses before it can be completed.

This is the same principle that shows up throughout jiu jitsu. Redirecting force works better than resisting it. The reverse shrimp is a clean application of that idea in a specific and high-stakes situation.

How to Do the Movement

The reverse shrimp is the opposite of the regular hip escape in terms of direction. Instead of pushing your hips away from your opponent, you are pulling them toward the side your opponent is transitioning to.

The key details are these. Your bottom foot pushes into the mat to generate the movement, the same foot you would use in a regular shrimp. Your hips rotate toward the direction of the attack rather than away from it. Your top knee drives across your body to create the momentum of the rotation. The movement needs to happen at the right moment in the transition, which is why drilling it until it becomes instinctive matters more than understanding it intellectually.

The timing window is real and it closes. If the armbar is already fully set and your opponent’s weight is properly distributed, the reverse shrimp is much harder to execute. The movement is most effective during the transition itself, when your opponent’s base is still shifting and their weight is not yet settled into the finish position.

A Note on Learning This the Right Way

I did not learn the reverse shrimp until I was a purple belt. I picked it up at a seminar in western Maryland and immediately understood why it had been missing from my game. The movement is not difficult once you understand the mechanics, but it also does not show up automatically just because someone shows it to you once.

The grapplers who use this movement reliably in rolls are the ones who drilled it deliberately until the body knew what to do without having to think about it. That is the only way to make a technique available under pressure.

If you are earlier in your jiu jitsu training, adding the reverse shrimp to your movement practice now means it will be there when you need it, instead of being something you remembered reading about after the fact.
