Butterfly Guard BJJ: The Ultimate Sweeping Guide

Butterfly Guard BJJ: Sweeps, Back Takes & Marcelo System

The butterfly guard is the great equalizer in BJJ.

If you are smaller than your opponent and you stay flat on your back, you are losing. Their weight pins you, their pressure builds, and passing becomes straightforward. The butterfly guard solves this — by sitting up, hooking inside their thighs, and using your legs as levers to elevate opponents twice your size.

Marcelo Garcia — multiple ADCC and World No-Gi Champion — used the butterfly guard to sweep, back take, and submit elite opponents who outweighed him by 20 to 40 kilograms. He proved that the position was not just a supplement to other guards — it was a complete, primary competition system that worked against the best grapplers in the world.

Position fact: The butterfly guard is one of the most effective positions in both gi and no-gi competition. According to BJJ Graph’s analysis, the butterfly sweep succeeds at significantly higher rates when combined with proper threat sequences — each defensive reaction the opponent makes opens a different attack.​

What is the butterfly guard?

The butterfly guard is a seated open guard position. You sit upright facing your opponent with both feet hooked inside their inner thighs — one hook per leg. Your instep sits against the inside of their thigh, pointing outward. Your head is above your hips throughout.

Unlike the closed guard where your legs lock around the opponent’s waist, butterfly guard controls a single leg each — creating two independent levers you can elevate, push, or redirect independently.

Unlike the spider guard which requires gi sleeve grips, butterfly guard is fully functional in both gi and no-gi — all controls are through body hooks and underhooks rather than fabric grips.

The position is named for the shape your legs make with both hooks in — bent outward like butterfly wings. It is a dynamic, active position. You are never static in butterfly guard — you are always adjusting hooks, fighting for underhooks, and setting up the next attack.

Why butterfly guard works

Three mechanical principles make butterfly guard effective.

1. Elevation. Your hooks inside the opponent’s thighs allow you to lift their body weight upward rather than pushing sideways. Elevation removes their base — when their feet leave the mat, they cannot base out or post effectively. This is why the butterfly sweep works against much larger opponents. You are not trying to move them sideways — you are lifting them straight up and tipping them over.

2. Hip-to-hip proximity. Butterfly guard keeps your hips close to your opponent’s hips. This close distance prevents them from generating passing power — they cannot build momentum from a distance. It also means every time they move, you feel it immediately and can respond.

3. Upper body control options. The underhook, overhook, arm drag, and two-on-one wrist control all work from butterfly guard. These controls neutralise the opponent’s base and determine which attack is available. The hook position provides the elevation; the upper body control provides the direction.

Marcelo Garcia — the defining practitioner

Marcelo Garcia’s butterfly guard is the most studied guard system in BJJ history. According to BJJ Heroes, Garcia won four ADCC World Championships and five No-Gi World Championships — the majority of his victories achieved by sweeping to top position using the butterfly hook sweep and the arm drag, then finishing from dominant positions.

His key innovations in the butterfly guard system:

The arm drag as a primary weapon. Most practitioners used the arm drag as an occasional entry. Garcia built it as a primary first-line attack — creating a constant threat that forced opponents to react, and using every reaction to set up the next attack.

Getting underneath the opponent. Garcia emphasised scooting his hips deep under the opponent’s centre of mass before elevating. This deep seated position made his elevation mechanical rather than muscular — he was not lifting with strength but with body position.

The guillotine connection. Garcia’s arm-in guillotine (Marcelotine) was inextricably linked to his butterfly guard. When opponents drove their head forward to defend the butterfly sweep, they walked directly into the arm-in guillotine. When they defended the guillotine, they backed off — opening the sweep. The two attacks defended each other.

Posture and hook position — the foundation

Before any sweep or submission, you need correct posture and hook position. Everything else in butterfly guard depends on these two elements being right.

Posture — sit up, head above hips

Your head must be above your hips throughout butterfly guard. The moment you lean back or fall onto your back, you lose the elevation mechanics that make the position work. If you feel your hips going back — scoot them forward immediately. Staying seated is the most important positional discipline in butterfly guard.

Hook position — instep inside, toes out

Your hooks go inside the opponent’s thighs — specifically the instep of your foot against the inside of their thigh. Toes point outward. The hook position should feel like you can lift upward naturally — not push sideways. If your hooks are on the outside of their thighs, you have lost the elevation angle and the sweep becomes much harder.

Distance — close is better

Butterfly guard requires hip-to-hip proximity. If your opponent creates distance — backing their hips away — your hooks lose leverage and your upper body controls become ineffective. Chase their hips constantly. Every time they create distance, scoot your hips toward them.

Core position rule: Head up, hooks inside, hips close. Check all three before every attack. If any is missing — reset it before attacking. Attacking from a broken position is the most common reason butterfly guard sweeps fail.

The underhook battle

Like the half guard, butterfly guard is an underhook battle. Whoever wins the underhook controls the position.

You have the underhook: Your arm is inside their armpit. You can control their posture, set up the hook sweep, execute the arm drag, and attack the guillotine. You are attacking.

They have the underhook: Their arm is inside your armpit. They can flatten you out, drive you back, and begin a guard pass. You are defending.

How to win the underhook: When they reach for your armpit, lower your elbow to block their entry. Then thread your arm under their arm from outside — driving your shoulder into their armpit. Keep your elbow tight to your ribs throughout the movement.

When they win the underhook: Do not fight it directly. Instead, go to the far side — overhook their near arm with your other arm and attack the arm drag on the opposite side. Their underhook on one side often opens the arm drag on the other.

Hook sweep — step by step

The hook sweep is the foundational butterfly guard attack. Every practitioner who plays butterfly guard learns this first. It works at every belt level and against opponents significantly larger than you.

1. Establish butterfly guard. Both hooks inside their inner thighs. Sitting upright. Head above hips.
2. Win the underhook. Drive one arm under their armpit — your shoulder into their armpit. This is your primary sweep lever.
3. Control their opposite arm. With your other hand, grip their opposite tricep, wrist, or sleeve. This prevents them from posting on that side to stop the sweep.
4. Scoot deep under them. Hip escape your body deeper under their centre of mass. Your hips should be under theirs before you begin the elevation.
5. Fall to your underhook shoulder. This is the critical detail most beginners miss. Do not fall to your back — fall to the shoulder of your underhook arm. This creates the angle for the elevation to work.
6. Elevate with your top hook. Drive your top hook upward — lifting their thigh. Simultaneously drive off your bottom foot into the mat.
7. Follow to top position. As they tip over, follow the sweep. Your underhook becomes the base for coming to top position in mount or side control.

Hook sweep key detail: Fall to the shoulder — not the back. This is where 80% of butterfly sweep failures originate. Falling flat eliminates the elevation angle completely. Shoulder-fall creates it. Drill this motion separately before adding the elevation.

Arm drag — back take entry

The arm drag is Marcelo Garcia’s primary butterfly guard weapon. It is more than a single technique — it is the threat that makes every other butterfly guard attack work.

1. From butterfly guard, reach and grab their near tricep with both hands — your far hand on top, your near hand underneath.
2. Pull their arm sharply across your centerline — dragging it past your body toward your far hip.
3. Simultaneously scoot your hips out to the side their arm is going.
4. Their arm is now past their body and their back is partially exposed. Reach for their far shoulder or waist with your near arm.
5. Pull yourself onto their back. Establish the seatbelt grip. Insert hooks. Attack the rear naked choke.

The arm drag also creates the hook sweep opportunity. When you threaten the arm drag, your opponent pulls their arm back and drives forward. That forward pressure with their weight coming toward you is the perfect setup for the hook sweep — you fall to the shoulder and elevate while they are already driving into you.

Sumi Gaeshi — the high sweep

The Sumi Gaeshi (sacrifice throw from judo) is the butterfly guard’s high-amplitude sweep. Where the hook sweep tips the opponent sideways, the Sumi Gaeshi throws them over your body in a high arc.

1. From butterfly guard, get a tight overhook on one arm and pull their posture forward — breaking them down toward you.
2. As their weight comes forward, fall backward — more dramatically than the hook sweep — driving one hook upward between their thighs.
3. As you fall back, the hook drives their leg up and their body follows — they go up and over you in a high arc.
4. Roll forward over your shoulder to follow them and land on top.

The Sumi Gaeshi is higher risk than the hook sweep — if the timing is off you end up flat on your back. But when executed correctly it is one of the most spectacular and effective sweeps in BJJ, landing you directly in mount with no scramble required.

Single leg entry from butterfly guard

When the opponent stands up to escape or pass butterfly guard, the single leg becomes available immediately.

1. As they stand, your hook that was inside their thigh is now wrapping the back of their knee or calf.
2. Sit up explosively and wrap your arms around their leg — double underhooks on the single leg.
3. From the single leg, you can complete a traditional single leg takedown, trip their far leg, or transition to the De La Riva guard.

The single leg entry makes standing up to escape butterfly guard dangerous. Your opponent faces a dilemma: stay kneeling (and face the hook sweep), or stand (and face the single leg). This is the butterfly guard dilemma in action.

---

X-guard transition

The X-guard is one of the most powerful transitions from butterfly guard — particularly when the opponent is standing or has one knee up.

From butterfly guard with one opponent foot planted forward:

1. Scoop under their front leg — your near arm goes under their knee, your far arm grabs their ankle.
2. Simultaneously, thread your far leg between their legs and hook behind their far thigh.
3. Your near leg comes up and hooks under their near thigh from the outside.
4. You now have the X-guard — both legs controlling one of their legs while your arms control the other. Their standing balance is completely compromised.
5. From X-guard, extend both legs to sweep them. They fall. Follow to top position.

The X-guard is particularly powerful against wrestlers and opponents who try to stand to escape butterfly guard. Standing up to avoid the butterfly hook sweep often puts them directly into X-guard range.

Threat-reaction table — reading the opponent

Butterfly guard works as a reaction system. Every defensive response your opponent makes opens a different attack. Understanding these connections is what turns butterfly guard from a collection of techniques into a complete system.

You threaten hook sweep →

They post their arm → Arm drag to back take
They drive forward → Sumi Gaeshi
They stand up → Single leg or X-guard

You threaten arm drag →

They pull arm back → Hook sweep (they drive forward)
They drive into you → Guillotine choke
They post far arm → Kimura on far arm

You threaten guillotine →

They posture up → Hook sweep opens
They roll to escape → Follow for back take
They tuck chin → Switch to arm drag

You threaten back take →

They turn to face you → Hook sweep
They flatten you → Recover seat, re-fight underhook
They sprawl → Sumi Gaeshi or sit-up sweep

Every attack in butterfly guard creates the conditions for another attack. You are not choosing techniques at random — you are reading the opponent’s reaction and following it to the correct counter.

Submissions from butterfly guard

Butterfly guard is primarily a sweeping and back-taking position — but each defensive reaction the opponent makes opens a submission.

Arm-in guillotine (Marcelotine)

When the opponent drives their head forward to defend the hook sweep or arm drag, their neck comes into range. Wrap the arm-in guillotine and fall back to closed guard or keep the butterfly hooks and finish. This is Marcelo Garcia’s most famous finish from butterfly guard. Full details in the guillotine choke guide.

Kimura from butterfly guard

When the opponent posts their far arm to prevent the arm drag or to stop the hook sweep, that arm is exposed in a kimura grip. Lock the figure-four and attack the kimura — or use it to sweep to top position using the kimura-sweep connection.

Triangle choke from butterfly guard

When the opponent reaches for your collar or head from butterfly guard, their arm is inside and their posture is compromised. Use the butterfly hook to elevate their hips while shooting the triangle on the near arm.

Leg lock entries

When the opponent steps around to pass butterfly guard, their legs come into heel hook and kneebar range. The outside heel hook from the step-around is a high-percentage no-gi option for advanced practitioners. The passing attempt that they use to escape the butterfly guard creates the leg entanglement entry.

Guard retention — staying seated

The most important retention concept in butterfly guard is one word: sit up.

When your opponent begins to pass, the instinct is to fall back and try to close your guard or frame from the bottom. This is wrong. Falling back removes the elevation mechanics and gives them top position. Instead:

• Scoot toward them. When they begin to pass, move your hips toward the pass direction — not away. This re-establishes your seated position and keeps the hooks available.
• Re-fight the underhook. The passing attempt often involves them winning the underhook. Fight to take it back. Your guard retention is directly connected to your underhook position.
• Use the granby roll. When they fully pass to one side, the granby roll (shoulder roll) can bring you back to a seated position facing them. See the spider guard section for full granby roll mechanics.
• Maintain at least one hook. If both hooks are removed simultaneously, pass is almost complete. Fight to maintain at least one hook — half butterfly guard — as a fallback.

Passing butterfly guard — top player concepts

If you are on top against butterfly guard, understanding the position helps you pass it efficiently.

The over-under pass

Step one leg outside their hook on one side while driving the other leg through the middle. This creates an asymmetric pressure that collapses the butterfly guard. Pin the inner thigh to the mat on the through side and complete the pass to side control or mount.

The combat base

Plant one knee on the mat between their hooks and one foot on the mat outside their hook. This combat base position is low and stable — they cannot elevate you effectively from below. From combat base, work systematically to strip one hook before engaging the pass.

Strip the underhook first

Before attempting any pass, strip the butterfly guard player’s underhook. An underhook gives them the sweep angle and the arm drag. A crossface — your arm across their neck/shoulder — replaces the underhook and significantly limits their attacking options.

Keep your hips heavy

The butterfly sweep fails when the opponent’s hips stay heavy and close to the mat. Drive your hips forward and downward — making it harder for the butterfly hooks to elevate you. This is the opposite of sprawling back — forward and down, not backward and away.

Gi vs no-gi differences

In the gi: Collar and sleeve grips add control layers to the butterfly guard system. A collar grip helps break posture and set up the hook sweep. Sleeve grips add control for the arm drag. The gi slows transitions slightly — giving more time to establish underhooks and hooks before the opponent can react.

In no-gi: Butterfly guard is actually considered one of the strongest no-gi positions precisely because it does not require fabric grips. All the controls — underhook, overhook, arm drag — function identically without the gi. Marcelo Garcia’s entire championship system was built in no-gi. Many coaches consider butterfly guard the best starting guard for no-gi beginners because of this fabric-independence.

Key no-gi adjustment: Without collar grips, posture breaking relies on two-on-one wrist control and underhook fighting. Establish the two-on-one wrist grip as your primary posture break in no-gi before transitioning to the arm drag or hook sweep.

Combo chains

• Hook sweep → Mount → Armbar: Sweep to mount, opponent bridges to escape, catch the armbar from mount.
• Arm drag → Back take → Rear naked choke: The most direct butterfly guard chain. Arm drag exposes the back. Back control produces the RNC.
• Guillotine → Hook sweep: Threaten the guillotine, opponent postures up to escape → hook sweep with their posturing motion.
• Hook sweep → Kimura: Opponent posts arm to stop sweep → lock the kimura on the posted arm.
• X-guard sweep → Half guard attack: X-guard sweep lands in top half guard → attack with kimura or knee slice pass.
• Butterfly guard → Closed guard: When they pass through your hooks, close your guard and attack from closed guard.

Common mistakes

• Falling to the back instead of the shoulder. The most common hook sweep error. Falling flat removes all elevation angle. Fall to the underhook shoulder specifically — this is what makes the elevation work.
• Hooks too high or too low. Too high on the hip loses elevation leverage. Too low on the knee creates pain and reduces hook control. The instep sits against the inner thigh — roughly knee height.
• Sitting too far back. If your hips are away from the opponent’s hips, your hooks have no elevation leverage. Chase their hips. Stay close enough that your hooks can lift.
• Static position. Staying in the same butterfly configuration waiting for the opponent to make a mistake. Butterfly guard requires constant movement — switching hooks, fighting for underhooks, creating threats.
• Attacking the sweep before winning the underhook. Without the underhook, the hook sweep has no direction. Fight for the underhook first. Every attack from butterfly guard is anchored to the underhook position.
• Losing the seated position without fighting to recover. When flattened or pushed back, many practitioners give up the position. Aggressively scoot back up to seated after every pass attempt. The seated position is your entire game — protect it.

Belt-level training guide

The BJJ belt system gives you clear milestones for butterfly guard development.

White belt — hooks and the hook sweep only

Learn the correct hook position and the hook sweep mechanics. Focus entirely on the shoulder-fall detail. Drill 15 to 20 hook sweep reps per session before rolling. See the white belt guide for the guard fundamentals that make butterfly guard development faster.

Blue and purple belt — arm drag and the dilemma system

Add the arm drag. Build the hook sweep-arm drag pair as a dilemma: sweep threat → they post → arm drag. Arm drag threat → they drive → hook sweep. Add the guillotine connection once the sweep-drag pair is automatic. The butterfly guard should be producing sweeps and back takes in live rolling regularly.

Brown and black belt — complete system

Add Sumi Gaeshi, X-guard transition, single leg entries, and leg lock connections. Develop a complete butterfly guard dilemma system where every defensive reaction has a predetermined counter. For advanced study, John Danaher’s Butterfly Guard instructional is the most comprehensive systematic framework available.

Champions built on butterfly guard

• Marcelo Garcia: 4x ADCC Champion, 5x World No-Gi Champion. The definitive butterfly guard practitioner — his arm drag and hook sweep system is the most studied guard game in BJJ history.
• Tom DeBlass: Has not had his guard passed in over a decade using the butterfly half guard system — combining butterfly hooks with half guard to create one of the most defensive and offensive guard systems available.
• Adam Wardzinski: Multiple BJJ World Champion known for his tripod sweep variation from butterfly guard — demonstrating that the position continues to yield new technical innovations at the highest level.
• Demian Maia: UFC middleweight contender and multiple BJJ World Champion. Used butterfly guard extensively in both sport BJJ and MMA — one of the few practitioners to successfully apply traditional BJJ guard attacks in high-level MMA.

The butterfly guard works because it turns the bottom position into an offensive platform. You are not surviving — you are attacking. Every movement your opponent makes is a potential sweep or back take opportunity when you understand the threat-reaction system.

Start with the hook position and the hook sweep. Drill the shoulder-fall until it is automatic. Add the arm drag. Build the dilemma: sweep or drag, every time. Then add the guillotine connection and the X-guard transition. Within six months of consistent drilling, butterfly guard becomes one of the most reliable attacking positions in your game — in gi, no-gi, and MMA.
