The Rolling Kimura from turtle top combines sweeping mechanics with submission threats to create one of the most effective dynamic attacks in modern grappling. The technique uses a secured kimura grip as the control mechanism while your body generates a rolling motion that forces the opponent to follow or risk immediate shoulder damage. The beauty of this technique lies in its dual-threat nature: the opponent must defend both positional advancement toward back control and the kimura submission itself, creating a dilemma that is extremely difficult to solve under pressure.
The rolling motion amplifies your leverage far beyond what arm strength alone produces, making this technique effective against larger opponents when executed with proper timing. The key mechanical insight is that your entire body weight drives the rotation through the opponent’s trapped shoulder, while their defensive options are limited by the figure-four grip configuration. When the roll completes successfully, you land in either back control with hooks available, kimura trap control for direct submission, or crucifix position with both arms trapped. Each finishing position represents a significant positional advantage that chains into high-percentage submissions.
From Position: Turtle (Top)
Key Attacking Principles
- Establish dominant kimura grip before initiating the roll to maintain control throughout the entire movement
- Use body weight and rotational momentum during the roll rather than relying on arm strength alone
- Keep hips close to the opponent’s body throughout the rotation to prevent separation and escape opportunities
- Maintain continuous shoulder pressure through the kimura grip to limit defensive options
- Time the roll when opponent is defensive and stationary rather than actively mobile or standing
- Stay connected to the opponent’s body throughout the transition so you move together as one unit
- Anticipate opponent’s reactions and be prepared to chain to crucifix, back take, or submission finish based on their response
Prerequisites
- Opponent must be in defensive turtle position with you positioned on top or to the side
- Clear access to one of the opponent’s arms, typically the far arm, for kimura grip establishment
- Ability to establish and maintain kimura grip configuration with figure-four on the arm
- Positional dominance with opponent not actively escaping or in the process of standing up
- Enough mat space to execute the rolling motion without environmental obstacles
- Strong base and balance to initiate the rolling motion without losing control of the grip
Execution Steps
- Secure kimura grip: From top turtle position, reach over the opponent’s back and secure a kimura grip on their far arm. Your same-side hand grips their wrist while your opposite hand threads under their arm and grabs your own wrist, creating the figure-four kimura configuration. Ensure the grip is tight and positioned at or above their elbow for maximum rotational control over the shoulder joint.
- Break down posture and isolate the arm: Pull the trapped arm away from the opponent’s body at approximately a 90-degree angle while driving your chest weight into their back. This breaks their base and prevents them from posting effectively with their free hand. Your head should be positioned near their far hip, creating downward pressure that pins their upper body and limits their ability to resist the upcoming rotation.
- Position body perpendicular for the roll: Adjust your body position so you are perpendicular to the opponent, with your hips near their trapped arm’s shoulder. Your inside leg closest to the opponent should be ready to post for stability, while your outside leg prepares to initiate the rolling motion by swinging over. Maintain constant tension on the kimura grip throughout this repositioning phase to prevent any arm recovery.
- Initiate the roll with leg drive: In one fluid motion, throw your outside leg over your own head while simultaneously pulling the kimura grip toward your chest. Roll diagonally over your outside shoulder at approximately a 45-degree angle, keeping your hips close to the opponent’s body throughout the rotation. Your momentum should pull the opponent’s upper body with you through the connected kimura grip, forcing them to rotate or accept shoulder damage.
- Maintain control during rotation: As you roll, keep the kimura grip tight and pull the opponent’s trapped arm across their body. Your body should rotate completely while maintaining physical connection to the opponent’s torso. Drive your near-side elbow to the mat to guide the roll direction and maintain balance. The opponent is forced to follow your rotation due to the submission pressure on their shoulder joint throughout the movement.
- Read opponent’s reaction and select finish: As the roll completes, immediately assess the opponent’s body position and defensive response. If their back is exposed, prepare to insert hooks for back control. If their far arm is available for trapping, set up the crucifix entry. If the kimura grip remains dominant and their arm is behind their back, begin applying rotational pressure to finish the shoulder lock directly. Your choice depends on which opening the opponent has given you.
- Secure finishing position and consolidate: Immediately consolidate your chosen position without hesitation. For back control, insert both hooks and establish seat belt grip with chest-to-back connection. For crucifix, trap the free arm between your legs while maintaining the kimura grip. For kimura finish, drive your hips toward their shoulder while rotating the trapped arm behind their back. Speed of consolidation during this transition moment determines whether you maintain your advantage or the opponent escapes.

Opponent Counters
- Opponent grabs their own belt or pants to prevent arm isolation (Effectiveness: Medium) - Your Response: Break the grip by using your body weight to pry the arm away while posting with your free hand. Alternatively, switch to attacking the near arm or transition to crucifix entry by trapping the gripping arm between your legs. → Leads to Turtle
- Opponent rolls with you to prevent the sweep and recover guard (Effectiveness: High) - Your Response: Maintain the kimura grip throughout their counter-roll and use their momentum to establish the submission finish from top position. If they overcommit to the counter-roll, transition to armbar by extending their arm as they rotate past neutral. → Leads to Turtle
- Opponent postures up and stands to escape the roll (Effectiveness: Medium) - Your Response: If they stand before you commit to the roll, abandon the rolling kimura and transition to standing back take or single leg takedown using the kimura grip to control their posture and break their balance forward. → Leads to Turtle
- Opponent drops their trapped shoulder to the mat to relieve pressure (Effectiveness: Low) - Your Response: This actually facilitates the roll. Follow their shoulder to the mat and continue the rolling motion. Their defensive movement helps complete your technique and often exposes their back more readily for hook insertion. → Leads to Back Control
- Opponent uses their free arm to frame against your hip or shoulder to block rotation (Effectiveness: Medium) - Your Response: Use your chest weight to collapse their frame before initiating the roll. Alternatively, trap their free arm with your leg to establish crucifix position, then proceed with the roll having control of both arms. → Leads to Turtle
Test Your Knowledge
Q1: What is the primary mechanical advantage of the rolling motion in the Rolling Kimura technique? A: The rolling motion uses your entire body weight and rotational momentum to amplify the leverage on the opponent’s shoulder joint, making it far more effective than relying on arm strength alone. The rotation also creates a dynamic situation where the opponent must move with you or risk serious shoulder injury, limiting their defensive options while simultaneously advancing your position toward back control or submission finish.
Q2: Why is it critical to maintain hip connection to the opponent’s body throughout the rolling kimura? A: Maintaining hip connection ensures that you and the opponent move as a single unit during the roll, preventing them from escaping the kimura grip or creating distance. If your hips separate from their body during the rotation, they can use the space to extract their arm, defend the submission, or potentially reverse the position. The hip connection transforms this from an isolated arm lock attempt into a full-body control technique.
Q3: Your opponent grabs their own belt with both hands to defend the arm isolation. How do you break this grip and continue the attack? A: Use your body weight rather than arm strength to break the defensive grip. Drive your chest into their back while peeling the trapped arm away from their body using the kimura configuration as a lever. If the grip persists, switch tactics by trapping their gripping arm between your legs to establish crucifix position, or circle to attack the near arm instead. You can also use a push-pull motion where you briefly push their arm toward their body then explosively pull it away when they relax their grip.
Q4: What is the correct timing to initiate the Rolling Kimura? A: The optimal timing is when the opponent is stationary and defensive in turtle position, with their weight settled and their base established but not actively mobile. Avoid initiating the roll when they are already moving, standing, or turning, as their momentum will work against your technique. The best moment is immediately after breaking their posture by pulling the trapped arm away from their body, when they are most unstable and committed to defending their arm rather than their position.
Q5: Your roll completes but you land with the opponent facing you rather than exposing their back. What finishing option do you pursue? A: If the opponent turns to face you during the roll, maintain the kimura grip and transition to finishing the kimura submission directly from the top position. Drive your hips toward their shoulder while rotating the trapped arm behind their back. Alternatively, if they are on their side, use the kimura grip to sweep them flat and transition to side control with the kimura trap maintained, which gives you a dominant control position with multiple submission options available.
Q6: Why is the Rolling Kimura considered a dilemma technique in modern BJJ? A: The Rolling Kimura creates a true dilemma because the opponent must simultaneously defend both a dangerous shoulder lock submission and prevent a major positional advancement to back control. If they focus entirely on defending the submission by keeping their arm close, they make the positional advancement easier because their base weakens. If they focus on preventing the back take by turning into you, they expose their shoulder to greater submission danger. This dual-threat nature makes the technique effective even when the opponent knows it is coming.
Q7: What direction should you roll and why does the angle matter for the Rolling Kimura? A: Roll diagonally over your outside shoulder at approximately a 45-degree angle rather than straight backward. This diagonal angle creates proper rotational momentum that loads the opponent’s shoulder joint progressively through the arc. Rolling straight backward produces weak leverage, slow rotation, and allows the opponent time to defend. The diagonal roll also keeps your body closer to the opponent throughout the movement, maintaining the critical hip connection that prevents separation and escape.
Q8: Your opponent begins standing up as you establish the kimura grip from turtle top. Should you abandon the technique or adapt? A: Adapt rather than abandon. If they have only begun to rise, accelerate your roll to use their upward momentum against them, executing the standing rolling kimura variant. If they are already mostly upright, transition to a standing kimura control where you use the grip to break their posture forward for a takedown or single leg. The kimura grip itself is valuable even without the roll, so maintain it and select the highest percentage follow-up based on how far they have progressed in their standup attempt.
Q9: How should you respond if the opponent counter-rolls with your Rolling Kimura attempt? A: If the opponent counter-rolls with your momentum, maintain the kimura grip and use their rolling motion to finish the submission from whatever position you land in. As they roll, keep your hips connected and apply pressure to the shoulder joint. You often end up in a top kimura trap position after their counter-roll completes. If they overcommit to the counter-roll, you can release the figure-four and transition to an armbar by extending their arm. The key is never releasing the grip regardless of which direction the roll goes.
Q10: What are the three primary finishing positions after a successful Rolling Kimura and how do you choose between them? A: The three primary finishes are: back control with hooks and seat belt, achieved when the opponent turns away from the kimura during the roll and exposes their back; crucifix position with both arms trapped, achieved when you catch their free arm with your legs during the roll; and direct kimura submission from top, achieved when the grip remains dominant and their arm is behind their back after the roll completes. Choose based on what the opponent gives you. If their back is exposed, take back control for the highest positional value. If their free arm is reachable, trap it for crucifix. If neither is available but the kimura grip is strong, finish the shoulder lock directly.
Safety Considerations
The Rolling Kimura involves significant rotational stress on the shoulder joint and must be practiced with appropriate caution and progression. Always start with zero resistance and gradually build up to full-speed application over weeks of dedicated practice. Communicate clearly with training partners about the shoulder pressure, and both partners should understand proper tap protocols before drilling. The person executing the technique must maintain controlled movement throughout the roll and never jerk or spike the rotation, as this can cause shoulder injuries even without full submission pressure. For the person defending, tap early when you feel significant shoulder discomfort, as shoulder injuries can be severe with long recovery times. When first learning, use crash pads or soft surfaces to practice the rolling mechanics safely. In competition or advanced training, be aware that the momentum of the roll can create unexpected joint stress, so maintain awareness and respect your partner’s safety at all times.
