The Turtle to Truck Entry is the critical initial phase of establishing the Truck position from behind a turtled opponent. Unlike the full Turtle to Truck transition which encompasses the entire sequence from turtle top to consolidated Truck control, this entry focuses specifically on the most technically demanding portion: threading the near-side leg hook through the opponent’s legs and locking the initial leg entanglement. The entry is the make-or-break moment where most failures occur, as the opponent’s defensive window is widest before any leg control is established.
This technique exploits the turtle position’s structural vulnerability to lateral leg attacks. When an opponent focuses on defending their neck and preventing traditional seatbelt back takes, their far leg becomes accessible for hooking. The entry requires precise coordination between your reaching arm grip on the far leg and your near-side leg threading simultaneously. Timing is paramount: the entry must occur when the opponent’s weight is committed forward onto their hands, limiting their ability to sit back or stand explosively.
The Turtle to Truck Entry is a gateway to the entire Twister submission system. Once the initial hook is threaded and the leg triangle begins to form, the opponent’s defensive options narrow dramatically. The entry creates an immediate fork: the opponent must choose between defending the leg entanglement (exposing their back) or defending their back (allowing the Truck to consolidate). This dilemma-based attacking framework makes the entry exceptionally valuable for practitioners who want to develop a systematic turtle attacking game beyond conventional back takes.
From Position: Turtle (Top)
Key Attacking Principles
- Thread the near-side leg first while maintaining upper body control to prevent escape during the vulnerable insertion phase
- Time the entry when opponent’s weight is forward on their hands, not sitting back on their heels
- Coordinate the reaching arm grip on the far leg with simultaneous leg threading for a single fluid motion
- Maintain perpendicular body angle relative to the opponent to maximize leverage and minimize their defensive options
- Never release all upper body control points during the leg insertion phase
- Use lateral hip pressure against the opponent’s near hip to prevent them from turning into you during entry
- Recognize when the entry window has closed and transition to alternative attacks rather than forcing a compromised entry
Prerequisites
- Opponent in turtle position with weight distributed forward onto their hands and knees elevated
- You are positioned behind or perpendicular to the opponent with chest pressure on their upper back or ribs
- At least one upper body control point established: cross-face, collar tie, overhook, or shoulder pressure
- Clear line of access to opponent’s far leg without their elbow blocking the path
- Opponent is not actively in the process of a granby roll, standup, or explosive guard recovery
- Your hips are lower than or level with the opponent’s hips to prevent them from sitting back into you
Execution Steps
- Establish perpendicular chest pressure: Position your chest firmly against the opponent’s near-side ribs, angling your body perpendicular to their spine. Your near-side arm should have a cross-face or collar tie controlling their head and preventing forward movement. Drop your hips low and heavy against their near hip to anchor your position and limit their lateral escape options.
- Reach for the far leg: Extend your far arm under the opponent’s torso, reaching across to grip the inside of their far knee or shin. Pull the far leg slightly toward you to create slack and break their four-point base symmetry. This grip is the anchor for the entire entry; without it, the leg thread will fail. Maintain chest pressure throughout to prevent them from collapsing their turtle or sitting through.
- Thread the near-side leg hook: Simultaneously with the far leg grip, thread your near-side leg (closest to opponent’s hips) underneath their body, inserting your shin behind their far thigh. Your foot should emerge on the opposite side of their body. Use a scooping hip motion to drive the leg through rather than kicking, which maintains your base and prevents telegraphing the entry.
- Secure the initial hook position: Once your shin is threaded behind their thigh, flex your foot and press your shin firmly against the back of their trapped leg. Use your far leg grip to prevent them from straightening their trapped leg or pulling it free. Your near-side arm maintains head control while your body weight pins their hip, creating a three-point control framework: head, hip, and leg.
- Begin the leg triangle formation: Bring your far leg over and begin locking it with your near leg in a figure-four or triangle configuration. Your near foot should seat into your far leg’s knee pit. Apply lateral pressure by extending your hips away from the opponent while squeezing the triangle, which pulls their trapped leg away from their body and compromises their base structure.
- Transition to side-lying Truck position: Roll onto your near-side hip while maintaining the leg triangle lock, facing the same direction as your opponent. Shift your chest contact from their ribs to their lower back or hip area. Release the cross-face and establish a grip on their far arm or shoulder to control their upper body rotation. You are now in the initial Truck configuration with the leg entanglement established.
- Consolidate Truck control: Tighten the leg triangle by actively squeezing and extending your hips. Control their upper body by reaching across for their far wrist, underhook, or chin. Ensure your back is not flat on the mat but angled onto your hip for mobility. From here, you have established full Truck entry with access to Twister, calf slicer, banana split, and back take options.

Opponent Counters
- Opponent sits back explosively before the leg thread is completed, crushing your reaching arm and preventing hook insertion (Effectiveness: High) - Your Response: Abandon the Truck entry immediately and use the momentum of their sit-back to transition to seatbelt back control. Your chest pressure on their ribs gives you a head start on the harness grip as they move backward. Alternatively, switch to Crab Ride position if they only partially sit back. → Leads to Turtle
- Opponent pulls their far leg away and straightens it before you can lock the triangle, removing the target limb entirely (Effectiveness: High) - Your Response: Maintain your threading leg position and hunt for the leg again using your far arm. If they extend their leg completely, switch your attack to a traditional back take since extending one leg compromises their turtle base. The failed entry has already disrupted their defensive structure. → Leads to Turtle
- Opponent performs an explosive forward roll or granby roll as they feel the leg thread beginning (Effectiveness: Medium) - Your Response: Follow the roll while maintaining your threading leg contact. Their rotation often helps complete the Truck entry from the opposite angle as your leg stays hooked during the roll. If you lose the hook during the roll, transition to back control by following their momentum and establishing seatbelt grip. → Leads to Truck
- Opponent drives their near elbow into your reaching arm to block access to the far leg (Effectiveness: Medium) - Your Response: Use your cross-face to push their head away, which opens the elbow gap. Alternatively, switch your reaching angle by going over their back instead of under to access the far leg from above. If the block persists, transition to front headlock attacks since their elbow commitment limits their defensive options against chokes. → Leads to Turtle
- Opponent stands up to both feet in a wrestler’s stance before you can establish the hook (Effectiveness: Medium) - Your Response: Maintain grip on their far leg and use it as a trip anchor while driving forward to return them to turtle. If they fully stand, transition to a body lock or single leg position. The standing posture is less stable than turtle for resisting your weight, so driving forward is often effective at collapsing them back down. → Leads to Half Guard
Test Your Knowledge
Q1: What is the primary goal of the Turtle to Truck Entry and how does it differ from a traditional back take? A: The primary goal is to thread a leg hook through the opponent’s legs and establish the initial leg triangle that defines Truck position. Unlike a traditional back take which targets seatbelt control and hook insertion on the opponent’s hips, the Truck entry targets leg entanglement that controls the opponent’s lower body. This creates a fundamentally different attacking framework: the Truck opens access to the Twister submission system, calf slicers, and banana splits rather than the rear naked choke and collar attacks of standard back control.
Q2: Which leg should you thread first during the entry and why is using the wrong leg a critical mechanical error? A: You must thread the near-side leg (the leg closest to the opponent’s hips) first. The near leg has the correct insertion angle because your hip is already adjacent to their body, allowing a smooth scooping motion. Threading the far leg first creates an awkward body angle that compromises your base, reduces leverage for the subsequent triangle lock, and positions your weight incorrectly relative to the opponent. The near leg also benefits from your chest pressure anchoring the entry, whereas the far leg would require lifting away from the opponent to thread.
Q3: Your opponent’s weight is sitting back on their heels in turtle - should you attempt the Truck entry? A: No. When the opponent’s weight is back on their heels, they have explosive backward movement options including standing up, sitting through to guard, or collapsing the turtle to prevent leg access. The Truck entry requires the opponent’s weight to be forward on their hands, which loads the front of their base and limits backward defensive reactions. If their weight is back, use alternative attacks like a traditional back take attempt or front headlock to force them to shift weight forward, creating the entry window for the Truck.
Q4: What are the three simultaneous control points you must maintain during the hook threading phase? A: First, upper body control through a cross-face, collar tie, or shoulder grip that prevents the opponent from standing, granby rolling, or sitting through. Second, the far arm grip on the opponent’s far knee or shin that anchors the target leg and prevents extraction. Third, chest or hip pressure against the opponent’s near-side body that pins them in place and prevents lateral escape. Losing any one of these three points during the threading phase creates a defensive window the opponent can exploit to escape before the leg entanglement is established.
Q5: You have threaded your hook but the opponent begins extracting their trapped leg before you lock the triangle - what is your response? A: Immediately accelerate the triangle lock by driving your far leg over to meet your near foot. Simultaneously extend your hips away from the opponent to create tension on the trapped leg, making extraction harder. If the leg is nearly free, abandon the triangle attempt and use your threading leg to transition to a traditional back hook while re-establishing seatbelt control. The failed Truck entry has already disrupted their turtle structure, making the subsequent back take attempt higher percentage than it would have been before the entry.
Q6: How should you generate the force for threading your leg through - explosive kick or scooping hip motion? A: Always use a controlled scooping hip motion rather than an explosive kick. The hip-driven motion keeps your base stable, maintains chest pressure on the opponent, and does not telegraph the entry attempt. An explosive kick lifts your weight off the opponent, creates visible movement the opponent can react to, and often causes your shin to bounce off their thigh gap instead of threading through it. The scooping motion uses your hip as the power source while your shin slides smoothly through the available space like threading a needle.
Q7: Your opponent performs an explosive granby roll just as you begin threading the hook - how do you respond? A: Follow the granby roll while maintaining contact with your threading leg. The key insight is that their rotation often helps complete the entry from the opposite angle, as your leg stays hooked during their movement. Maintain chest contact and grip on their far leg throughout the roll. If you lose the hook during the roll, immediately transition to back control by following their momentum with seatbelt grip establishment. The worst response is to freeze or pull away, as the opponent will complete the granby and recover guard while you reset to neutral.
Q8: Why must you transition to a perpendicular side-lying position after locking the triangle rather than staying on top of the opponent? A: The perpendicular side-lying position is essential because it creates the proper mechanical angles for all Truck submissions. Staying on top limits your ability to extend your hips (needed for Twister and calf slicer pressure), allows the opponent to potentially bridge and roll you over their head, and prevents you from controlling their upper body for submission setups. The side-lying perpendicular angle also maximizes your leg triangle’s effectiveness by creating lateral pressure on the trapped leg rather than downward pressure, which is biomechanically stronger for controlling the entanglement.
Q9: What attack chain should you follow if the opponent defends the Truck entry by blocking your reaching arm with their near elbow? A: First, use your cross-face to push their head away, which structurally opens the elbow gap by forcing their upper body to follow their head. If the gap still does not open, switch your attack vector entirely: their elbow commitment to blocking the Truck entry means their neck is less defended, so transition to front headlock attacks such as anaconda or darce choke setups. Alternatively, the committed elbow creates an arm isolation opportunity for crucifix entry if you can trap the blocking arm. The principle is to attack whatever the opponent exposes by defending something else.
Q10: How does the Turtle to Truck Entry create a defensive dilemma for the opponent, and what two things must they choose between? A: The entry forces the opponent to choose between defending the leg entanglement or defending their back. If they focus on extracting their trapped leg by straightening it or pulling away, they necessarily open space and compromise their turtle structure, making traditional back takes easier. If they focus on maintaining a tight turtle and defending the back with elbow-to-knee structure, they cannot address the leg threading happening below. This fork means the opponent cannot optimally defend both threats simultaneously, and the attacker can read their defensive priority and attack the opposite opening.
Q11: Your opponent posts their far hand on the mat during the entry attempt - how do you exploit this? A: A posted far hand means the opponent has removed that arm from their defensive shell to create a base point. This opens two immediate opportunities: first, the posting arm can no longer protect the gap between their elbow and knee on that side, making the far leg grip and hook threading easier. Second, the posted arm itself becomes vulnerable to a kimura attack or can be trapped for a crucifix entry. The best response is to capitalize on the opened elbow-knee gap by accelerating your hook thread, since their posting has prioritized base over defending the leg entry path.
Q12: What grip on the opponent’s far leg is most critical for the entry, and what happens if you lose it mid-thread? A: The grip on the inside of the opponent’s far knee or shin is the anchor for the entire entry. This grip serves three functions: it prevents the opponent from pulling their leg away, it creates the slack needed for your threading leg to pass through, and it breaks their four-point base symmetry. If you lose this grip mid-thread, the opponent can immediately straighten their far leg and pull it away from your threading shin, collapsing the entry. If the grip is lost after your shin is partially through, you must accelerate the triangle lock with your far leg before the opponent can react, as the window without the anchor grip is extremely narrow.
Safety Considerations
The Turtle to Truck Entry involves leg entanglement that can generate significant torque on the knee joint of both practitioners. During the threading phase, the inserting practitioner should use controlled hip-driven motion rather than explosive kicks to prevent accidentally striking the training partner’s inner thigh or groin. Once the leg triangle is locked, apply pressure gradually and maintain communication with your partner about intensity levels. The trapped leg is particularly vulnerable to lateral knee stress during the triangle lock, so release immediately upon any tap signal. Partners in turtle should tap early if they feel knee pressure before the triangle fully locks rather than waiting, as the pressure can escalate quickly once the configuration is established. Avoid forcing the entry if the angle is incorrect - reset and try again rather than cranking the leg into position. Be especially careful during the roll to side-lying position, as awkward weight distribution with legs entangled can strain knee ligaments for both practitioners.
