The berimbolo was built by flexible, explosive young athletes and taught as a gift of the body. Mikey Musumeci rebuilt it as a machine — a sequence of stable checkpoints from both De la Riva and reverse De la Riva that a stiff, slow, or small grappler can still ride to the back. This is how the sport's most acrobatic sweep became its most teachable.
For most of the 2010s, the berimbolo belonged to a specific kind of grappler: young, hyper-flexible, explosive, and usually built like a whippet. It was the signature of the Mendes brothers and the Miyao brothers — a blur of inversion out of De la Riva that spun the bottom player under his opponent and out the back door before the top man understood he was being passed the wrong way. It scored more points than anything else in the modern gi. It also looked, to most adult hobbyists and most heavier competitors, like a magic trick they were not built to perform.
Mikey Musumeci watched the same berimbolo everyone else did and drew the opposite conclusion. The problem, in his telling, was never that the movement demanded a gymnast's spine. The problem was that it had been taught as if it did — as one continuous acrobatic motion instead of a series of separate, stable positions, each of which could be reached slowly, held against resistance, and only then connected to the next. Break the spin into checkpoints, he argued, and the flexibility requirement mostly disappears. What is left is grips, angles, and wedges: mechanics, not athleticism.
Across four IBJJF gi World titles in the sport's lightest divisions, Musumeci made that argument on the mat. Opponents knew the berimbolo was coming — it is the most-scouted sequence in his game, and he is the most-scouted small man in the gi — and they lost their backs anyway, not to a faster spin but to a control they could not interrupt. Then he codified the whole method in a series of instructionals built around a single, deliberately unglamorous promise: you do not need to be flexible to do this.
This is not a story about a prodigy who could bend in ways other people cannot. It is a story about what happens when someone decides the sport's most athletic technique is actually its most mechanical, and rebuilds it so the rest of us can steal it.
Musumeci's berimbolo system is the clearest proof that the sport's most acrobatic-looking sweep is really a chain of static checkpoints — a back-take game runnable from both De la Riva and reverse De la Riva on control and grips rather than flexibility or speed, which is exactly why it travels to grapplers who will never invert like the Miyaos.
The berimbolo is not Musumeci's invention, and the system is honest about that. Its value is in the re-engineering, not the origin — so the origin is worth getting right.
The movement was born from the De la Riva guard, the outside-hook open guard that Ricardo De la Riva developed at Carlson Gracie's Copacabana academy in the 1980s to survive larger, passing-minded opponents. The De la Riva hook — the lead leg threaded around the outside of the opponent's near leg — gives the bottom player a lever on the opponent's base, and somewhere in that lever is the seed of the inversion. The specific back-take that grew out of it is generally credited to , who by community accounts developed it in his purple-belt years in the mid-2000s; the name "berimbolo" is usually attributed to , who reportedly coined the term for the whirling motion. (Both attributions circulate widely in the community but are difficult to pin to a single primary document; this desk flags them as received history — see Known open items.)
The technique became a competitive force one generation later. The Mendes brothers — Rafael and Guilherme, of Atos and later Art of Jiu Jitsu — drove the berimbolo into the elite gi game around 2010, and the Miyao brothers, Paulo and João, extended it through their breakout in 2011–2012, adding the crab ride and the twister hook that turned a single sweep into a networked back-attack. By the mid-2010s the berimbolo was the defining sequence of lightweight gi jiu-jitsu, and the sport had absorbed a matching assumption: that it was a young, flexible, explosive player's weapon, unavailable to everyone else.
Musumeci is the figure who broke that assumption, and the record gives him the standing to. Michael Musumeci Jr., born 7 July 1996 in Marlboro, New Jersey, was raised in the sport alongside his older sister Tammi Musumeci; both became IBJJF black-belt world champions. His competitive lineage runs through Nova União, the Rio de Janeiro school founded by André Pederneiras, and he earned his black belt in 2015 from Gilbert "Durinho" Burns. At 5'7" he competes in the lightest gi classes — roosterweight and light-featherweight — where a strength-based game is a losing proposition and leverage is the only durable edge.
His record is precise and frequently mis-stated: Musumeci is the first American to win more than one IBJJF World Championship at black belt — the first American repeat gi world champion — not the first American world champion at all, a distinction Rafael Lovato Jr. holds from 2007. He won the IBJJF gi Worlds in 2017, 2018, 2019, and 2021, and an IBJJF No-Gi Worlds in 2016. The inverted guard and the back-take were not a highlight-reel garnish across those runs; they were the engine of the record.
The codification is unambiguous and recent. Musumeci built out The Berimbolo System through BJJ Fanatics — a multi-volume gi series covering the crab ride, the leg drag and inverted leg drag, the knee wedge, the twister hook, and his signature Mikey Hook — and followed it with a No Gi Berimbolo System and The Reverse De la Riva System, the latter carrying the berimbolo's mirror-image back-takes, including the "kiss of the dragon" reverse-berimbolo inversion. Those instructionals are the system's paper trail: they treat the berimbolo not as one technique but as an ordered method, taught the same way twice — once from De la Riva, once from its reverse — for both uniforms. When this desk calls it a "system," that is the evidence.
The parent of this article — the berimbolo as a technique — describes a movement: invert out of De la Riva, spin under the opponent, come up on the back. That description is correct and, for Musumeci's purposes, useless. A technique page tells you what the berimbolo is. It cannot tell you the thing his whole system is about: the ordered, body-independent method for arriving at the back with control, from either of two guards, under either ruleset. Four principles hold it together.
1. The spin is a chain of checkpoints, not a movement.
This is the load-bearing idea, and it is what separates Musumeci's berimbolo from the one the Miyaos made famous. Taught as a single acrobatic rotation, the berimbolo genuinely does reward a flexible spine and explosive hips — which is why most people who try it either hurt their neck or hand over their back. Musumeci breaks the same rotation into discrete positions: the De la Riva hook and the grips, the initial off-balance, the inversion onto the shoulders, the crab-ride underneath, and the emergence to the back. Each is a place you can stop. The instruction is that you should be able to occupy any checkpoint statically, against a resisting partner, before you ever connect two of them at speed. Flexibility stops being a requirement because you are no longer bending through the movement; you are stepping through stations. Speed stops being a requirement because control, not momentum, holds each station in place.
2. Two doors — De la Riva and reverse De la Riva.
Most berimbolo instruction lives entirely inside the standard De la Riva hook. Musumeci's codification is unusual in giving equal weight to the reverse De la Riva — the mirror guard where the hook turns to the inside of the opponent's leg, built to eat the knee-cut pass that beats classic De la Riva. From reverse De la Riva, the same back-take runs in mirror image: the "kiss of the dragon," a reverse-berimbolo inversion that spins the bottom player under the inside of the leg to the back. The strategic point is that the two guards cover each other. When an opponent adjusts his passing to deny the standard berimbolo, he almost always opens the reverse-De-la-Riva door, and vice versa. A player who carries only one hook can be shut down by taking that hook away; a player who carries both is choosing which back-take, not whether one is available.
3. Kill the pass and the far hip before you invert.
The fastest way to lose your back is to invert first and control second. Musumeci's entries are built the other way around: the near leg and the opponent's hip are pinned before the shoulders go to the mat. The crab ride — riding underneath the opponent with a hook controlling his hip from below — is the central control position, the checkpoint everything else passes through. The leg drag and inverted leg drag are used to steer the opponent's leg across and kill his ability to square back up; the knee wedge and twister hook jam the opponent's base so he cannot simply stand and pull free while the bottom player is upside down. Only once the hip is dead does the inversion become safe. This is the same control-first logic that runs through his leg game, and it is why the back-take finishes against opponents strong enough to rip through a berimbolo attempted without it.
4. The destination is the second hook, not the sweep.
A berimbolo that dumps the opponent to the mat and scores a sweep is, in Musumeci's framing, an incomplete rep. The point of the whole chain is back control — the sport's highest-value position — reached with both hooks in and the seatbelt secured, not merely a two- or four-point transition. His signature Mikey Hook belongs here: a wedged, retention-first hook configuration that keeps the bottom player attached to the back through the scramble that follows the inversion, when a conventional berimbolo often spits the attacker off before the second hook lands. The system treats the moment of emergence — coming up out of the crab ride onto the opponent's back — as the actual crux, and builds its most detailed instruction around securing the back rather than around the flashy spin that gets there.
What a section of the generic berimbolo page could never say is this: the berimbolo, in Musumeci's hands, is not an athletic sweep you attempt out of De la Riva — it is a two-doored, checkpoint-based back-take method, taught identically from De la Riva and its reverse and across gi and no-gi, engineered so that the least flexible, least explosive, smallest grappler in the room can still arrive on the back of a bigger one.
By 2026, the berimbolo system's influence is measured less in one competitor's bracket results than in how many ordinary grapplers now believe the movement is available to them.
The reframing is the legacy. For a decade the berimbolo carried an implicit gatekeeper — you have to be flexible — and Musumeci's instructionals are, above all, an argument against that gate. His public framing has been consistent: the game runs on "technique instead of flexibility or speed," on grips and body positions a non-athlete can hit rather than an acrobatic gift. That claim is why the two berimbolo series and the reverse-De-la-Riva series are usable by people who will never invert like the Miyao brothers. A generation of stiffer, older, and heavier hobbyists who had written the berimbolo off now has a blueprint pitched directly at them.
The competitive proof of concept came when Musumeci carried the inverted game out of the gi. In 2022 ONE Championship — the Singapore-based promotion built on striking and MMA — created a submission-grappling division around its lightest weight class, and around Musumeci specifically. On 1 October 2022 he defeated Cleber Sousa to become the inaugural ONE Flyweight Submission Grappling World Champion, and he held the belt until 5 September 2024. Under no-gi rules, with no lapels or sleeves to grip, the back-take had to survive on frames and wedges alone — and the No Gi Berimbolo System is the record of that adaptation, the same checkpoints rebuilt without the cloth. The berimbolo that gi traditionalists once dismissed as a points-farming gimmick became a back-attack that worked against larger opponents in a cage.
Musumeci's own game has since begun to move. In interviews across 2025 and 2026 he has described adding wrestling and top pressure to his repertoire, training with members of the Nurmagomedov camp — a notable pivot for a competitor whose identity was built on bottom-position inversion. This desk treats that shift as an unfinished story rather than a settled part of the berimbolo record. What is not in doubt is that the inverted back-take remains the through-line of his competitive identity, and the reference codification of a technique the sport spent a decade believing was reserved for the gifted few.
The berimbolo's role in Musumeci's career is better described as a pattern than as a single decisive bout — which is how this desk presents it, refusing to attach invented scores or timestamps to matches it cannot confirm against a primary scoresheet. Where a specific event is named, the surrounding detail is flagged.
White belt should not attempt the berimbolo yet — and that is the first lesson of the system. Before any inversion, the white belt learns the De la Riva hook and the grips that go with it, and learns to keep the guard rather than pass through it. Invert without control and you simply hand a bigger opponent your back.
Blue belt learns the berimbolo as a sequence of stops, not a spin. If you cannot hold the inverted position and the crab ride against a resisting partner, you cannot chain them. This is the rank at which Musumeci's "technique, not flexibility" framing does its real work: the blue belt who drills checkpoints beats the blue belt who drills the acrobatic version.
Purple belt adds the second door. The reverse De la Riva and its mirror back-take turn a single, scoutable attack into a two-sided dilemma. The purple belt stops thinking "berimbolo" and starts thinking "which back-take does his passing give me."
Brown belt connects the rulesets. The same checkpoints the brown belt drilled with lapel and sleeve grips get rebuilt on frames and wedges for no-gi, and the crab ride becomes the shared control position across both uniforms.
Black belt does what Musumeci did: refines the entries past the point where scouting helps. Every opponent knows the inversion is coming. The black belt takes the back anyway, because the advantage was never surprise — it was the control that holds each checkpoint in place.
1. Spinning instead of stepping through checkpoints. The most common error copying Musumeci is inverting explosively and hoping to come out on the back. The berimbolo is a chain of controlled positions; speed is a shortcut that fails against a good passer. Control, not momentum, is the actual mechanism.
2. Inverting before killing the hip. Going upside down without first pinning the near leg and the opponent's hip is how you donate your back in the scramble. The crab-ride control precedes the inversion, always — never the reverse.
3. Carrying only one hook. A player who trains only the standard De la Riva berimbolo can be shut down by a passer who denies that hook. The system's insurance is the reverse-De-la-Riva mirror; skipping it leaves half the back-takes on the table and makes the remaining half easy to scout.
4. Chasing the sweep and stopping there. Dumping the opponent for two points and losing the back is an incomplete rep. The destination is back control with both hooks and the seatbelt; the Mikey Hook exists precisely to keep you attached through the emergence, which is where most berimbolos fail.
5. Believing you are not built for it. The deepest misread is the one the system was written to correct: that the berimbolo requires a flexible, explosive body. Musumeci's entire premise — and his record in the sport's smallest divisions — argues that it requires grips, angles, and patience instead.
At open mat this week, isolate the checkpoint, not the spin. Start seated in front of a same-size partner in an open-guard exchange. Your only goal for a fifteen-minute round is to establish a De la Riva hook, off-balance the partner enough to invert onto your shoulders, and arrive in the crab ride underneath his hip — and stop there. No back-take, no second hook, no submission. Just reach the controlling position and hold it while your partner tries to flatten you and square back up.
You will get passed. Then you will get passed more slowly. Then you will hold the crab ride once. That checkpoint — control before the back-take — is the entire foundation of the system, and it is the part almost everyone skips on the way to the flashy inversion.
Add a second round in which, from that same crab ride, you are allowed a single objective: come up onto the partner's back and secure both hooks and the seatbelt, with no submission attempt. This isolates the emergence — the actual crux of the berimbolo — onto a controlled entry, exactly the order the system demands. Then, and only then, repeat the whole progression from the reverse De la Riva hook, so both doors get the same reps.
Musumeci's berimbolo system is a network of positions the rest of the sport has separately systematized. Trace it outward:
Every one of these positions was reached, in Musumeci's career, by a small grappler who decided the sport's most athletic technique was actually its most mechanical, and then spent a childhood proving it.
