The Basic Butterfly Sweep is a fundamental technique from the Butterfly Guard that exploits opponent’s forward pressure and balance. Using hooks underneath the opponent’s thighs combined with proper grip control and hip movement, the practitioner elevates and off-balances the opponent to achieve a dominant top position. This sweep is highly effective against opponents who attempt to establish base in your butterfly guard or pressure forward without proper posture. The technique relies on timing, leverage, and the mechanical advantage created by the butterfly hooks rather than pure strength. When executed properly, the Basic Butterfly Sweep can transition smoothly into mount, side control, or back control depending on the opponent’s defensive reactions. This is considered an essential technique for all BJJ practitioners and forms the foundation for more advanced butterfly guard sweeping systems.
From Position: Butterfly Guard (Bottom)
Key Attacking Principles
- Maintain active butterfly hooks with heels close to opponent’s hips for maximum elevation leverage
- Break opponent’s posture and control their upper body through grips before initiating sweep
- Use hip movement to create proper 45-degree angle and mechanical leverage before driving
- Time the sweep when opponent commits weight forward over your hooks
- Drive hooks upward and forward while pulling upper body grips to create unified rotational force
- Follow through with bodyweight to establish top position without disconnecting
- Maintain connection throughout the sweep to prevent escape and ensure consolidation
Prerequisites
- Butterfly guard established with both hooks under opponent’s thighs
- Secure grip control on opponent’s collar, sleeve, or overhooks
- Opponent’s weight committed forward or balanced neutrally over your hips
- Your hips mobile and positioned underneath opponent’s center of gravity
- Proper distance maintained - not too close to compress, not too far to lose hooks
- Active hook engagement with heels pulled toward opponent’s hips
Execution Steps
- Establish butterfly guard position: Secure butterfly guard with both hooks under opponent’s thighs, heels pulled in toward their hips. Sit up tall with active posture, controlling opponent’s upper body with collar and sleeve grips or underhooks. Your hips should be mobile and ready to move.
- Secure upper body control: Establish strong grip control - typically collar and sleeve grips, double underhooks, or overhook/underhook combinations. Pull opponent’s upper body down and forward to break their posture and bring their weight over your hips. This control is critical for preventing them from posting and defending the sweep.
- Create angle with hip movement: Shift your hips at a 45-degree angle away from the side you intend to sweep toward. This angling creates better leverage for the butterfly hook and positions your body to follow through into top position. Your spine should be curved toward the sweeping direction.
- Drive butterfly hook upward: Explosively extend the butterfly hook on the sweeping side upward and forward, driving through your heel and lifting opponent’s leg off the mat. Simultaneously pull their upper body in the direction of the sweep using your grips. The hook creates elevation while the grips create rotation.
- Roll opponent over your body: Continue driving the butterfly hook while pulling their upper body across your centerline. Fall back slightly on the sweeping side, allowing opponent’s momentum to roll over you. Your opposite butterfly hook helps stabilize and can be used to further off-balance them if needed.
- Follow through to top position: As opponent rolls over, immediately follow their movement by coming up on your knees and establishing top position. Drive your chest forward and maintain grip control to prevent them from recovering guard. Depending on the angle and their defensive reactions, you can land in mount, side control, or take the back.
- Consolidate position: Once on top, quickly establish control by securing proper weight distribution, controlling their hips and shoulders, and preventing guard recovery. If in mount, secure your base. If in side control, establish crossface and hip control. Maintain pressure to prevent escape attempts.

Opponent Counters
- Opponent posts hand on mat to block sweep (Effectiveness: High) - Your Response: Switch to opposite side butterfly sweep, attack posted arm with kimura, or transition to single leg X-guard by diving under the posted arm → Leads to Butterfly Guard
- Opponent sprawls hips back and creates distance (Effectiveness: High) - Your Response: Follow their movement by extending guard forward, switch to deep half guard entry, or stand up and pursue with front headlock control → Leads to Butterfly Guard
- Opponent steps over butterfly hook to establish headquarters position (Effectiveness: Medium) - Your Response: Immediately switch to single leg X-guard, attack the trapped leg, or transition to reverse De La Riva guard before they can pass → Leads to Butterfly Guard
- Opponent maintains strong upright posture and prevents forward weight commitment (Effectiveness: Medium) - Your Response: Use elevator sweep variation by pulling them forward with collar grip, or transition to seated guard with ankle picks and arm drags → Leads to Butterfly Guard
- Opponent counters by driving weight extremely heavy onto your chest (Effectiveness: Low) - Your Response: Use their forward pressure to enhance the sweep - their committed weight actually makes the basic butterfly sweep easier to execute with proper timing → Leads to Mount
Test Your Knowledge
Q1: What is the primary mechanical principle that makes the butterfly sweep effective? A: The butterfly sweep works by creating leverage through the butterfly hook which acts as a fulcrum point under the opponent’s center of gravity. When you drive the hook upward while simultaneously pulling their upper body forward and across, you create a rotational force that disrupts their base. The hook elevation combined with upper body control creates a mechanical advantage that allows a smaller person to sweep a larger opponent by exploiting physics rather than relying on strength.
Q2: What timing is optimal for executing the basic butterfly sweep? A: The optimal timing is when the opponent commits their weight forward over your hips, creating forward pressure. This can occur naturally when they attempt to pass or pressure into you, or you can manufacture it by pulling them forward with your grips. The key is to wait for the moment their weight is distributed over your butterfly hooks before initiating the sweep. Attempting the sweep when their weight is back or evenly distributed allows them to easily post and defend.
Q3: Your opponent posts their right hand on the mat when you attempt to sweep them to your left - what are your best responses? A: When opponent posts their hand, you have several high-percentage options: First, immediately switch to sweeping the opposite direction since posting on one side creates compromised base on the other. Second, attack the posted arm with a kimura lock since it is extended and bearing weight, making it vulnerable to grip capture. Third, transition to single leg X-guard by diving your shoulder under the posted arm and controlling their far leg. The critical principle is recognizing the post instantly and flowing to your counter rather than forcing the original sweep direction.
Q4: Why is creating a 45-degree hip angle critical before driving the butterfly sweep? A: Creating the angle before the sweep serves multiple biomechanical purposes: It positions your body to follow through into top position naturally without needing to reposition mid-sweep. It creates better leverage for the butterfly hook to drive upward and forward rather than just straight up, generating rotational rather than purely vertical force. It curves your spine toward the sweeping direction which helps generate torque. And it makes it harder for the opponent to post on the sweeping side because your angle takes them off their centerline. Without the angle, the sweep becomes a pure strength battle.
Q5: What are the most effective grip combinations for the basic butterfly sweep and when should you choose each? A: The most effective grip combinations are: collar and sleeve grips which provide maximum upper body control and prevent posting on the sleeve side; double underhooks which are extremely powerful for pulling opponent forward and preventing base, particularly effective in no-gi; and overhook/underhook combination which creates asymmetrical control ideal for directional sweeping. Each grip accomplishes two objectives: breaking opponent’s posture to commit weight forward, and preventing them from posting hands to defend. Choose collar-sleeve in gi when distance exists, double underhooks when you can close distance, and overhook-underhook when opponent commits an underhook first.
Q6: What should you do immediately after completing the butterfly sweep to consolidate top position? A: Immediately after the sweep completes, follow the opponent’s momentum without disconnecting and establish dominant top position. Come up on your knees while maintaining grip control, drive your chest forward to prevent guard recovery, and quickly transition to mount by staying tight and walking your knees up alongside their torso. If they turn to their side during the sweep, follow to side control with crossface and hip control, or take the back if they expose it. The critical principle is maintaining continuous pressure and connection throughout the transition without pausing or creating separation.
Q7: Your opponent is sitting very upright with good posture and refuses to commit weight forward - how do you create the conditions for the butterfly sweep? A: Against an opponent with strong upright posture, you must manufacture forward weight commitment through indirect methods. Use an arm drag to force them to reach forward and recover balance, creating the brief forward weight shift needed. Threaten a guillotine choke by snapping their head down, which forces defensive posture correction that commits weight forward. Pull aggressively on collar grips to break their posture incrementally. If they absolutely refuse to come forward, transition to elevator sweep which works against upright posture, or switch to X-guard entries by attacking their legs from underneath.
Q8: What distinguishes a failed butterfly sweep attempt from a properly abandoned one, and how does this affect your position? A: A failed butterfly sweep involves fully committing to the drive without proper setup, exhausting energy, and ending flat on your back with compromised guard retention. A properly abandoned sweep recognizes early that the opponent has defended successfully - posting their hand, sprawling, or establishing dominant grips - and immediately transitions to a secondary attack. The abandoned sweep maintains your seated posture, hook engagement, and grip control, allowing you to chain to X-guard, single leg X, arm drag, or the opposite-direction sweep. The key differentiator is whether you maintain your structural position and offensive initiative rather than committing past the point of recovery.
Q9: How do grip requirements change between gi and no-gi butterfly sweep execution? A: In gi, collar and sleeve grips provide precise directional control and strong posting prevention, with the collar grip enabling powerful pulling force to break posture. In no-gi, you rely on underhooks, overhooks, collar ties, and wrist control which require closer distance and more dynamic grip fighting. No-gi butterfly sweeps demand tighter body connection since grips are less secure, making double underhooks and body lock configurations more important. The fundamental sweep mechanics remain identical but no-gi requires faster execution because control windows are shorter, and you must emphasize body-to-body contact rather than fabric-based control.
Q10: What is the relationship between the butterfly sweep and subsequent guard transition options when the sweep is partially successful? A: A partially successful butterfly sweep where the opponent is elevated but recovers creates several high-value transition opportunities. If they post a hand during elevation, their weight shifts to that posting arm, opening kimura attacks and opposite-direction sweeps. If they sprawl their hips back to avoid being swept, the distance created is ideal for X-guard or single leg X-guard entries by following their retreating legs. If they step one leg over your hook to base out, the resulting asymmetric position feeds directly into reverse De La Riva or deep half guard entries. The butterfly sweep thus functions as a forcing mechanism that creates reactions exploitable through the broader butterfly guard system.
Safety Considerations
The basic butterfly sweep is generally a low-risk technique when practiced correctly. However, practitioners should be aware of several safety considerations. When drilling, ensure controlled execution to avoid slamming your partner, especially on hard surfaces. Begin with slow, cooperative repetitions to develop proper mechanics before adding speed and resistance. For the person being swept, learn to breakfall properly by slapping the mat with your arm to disperse impact energy. Avoid stiff-arming or posting with straight arms when defending the sweep, as this can lead to wrist, elbow, or shoulder injuries. When executing the sweep, maintain control of your partner’s upper body throughout to prevent uncontrolled falls. If you have knee issues, be cautious with the butterfly hook position as it requires some knee flexibility and can stress the joint if hooks are too shallow or if weight is dropped suddenly. Start with light resistance and gradually increase intensity as your body adapts to the positions and movements.
