Gilbert Burns was born on July 20, 1986, in Niterói, Brazil — a city that also produced celebrated grapplers Ricardo Arona and Paulo Filho. His earliest martial arts experience came around age four or five, when his father rented the family patio to a karate instructor. Burns took to the sport immediately, competing frequently for roughly three years until the instructor relocated and the classes ended.

Real financial pressures shaped his childhood. His father worked as an upholsterer, running car upholstery and repair from home, and the brothers regularly helped out. Burns and his brothers also battled recurring bronchitis, and a doctor's recommendation to pursue sport for their health added further motivation to stay active.

The discovery of jiu-jitsu arrived through an almost cinematic coincidence. During an upholstery job, a gi turned up inside a client's car — and the car's owner was a BJJ professor. Burns's father arranged a three-month training scholarship, gis included, as payment in lieu of cash. After Burns competed after just one month of training and performed well beyond expectations, the brothers earned extended support from the instructor and never left the mats. Burns began competing as a white belt from age 12.

The family's dedication to martial arts runs deep. His older brother Herbert — whose nickname 'Todo-Duro' (meaning 'hard man') directly inspired Gilbert's own nickname 'Durinho,' meaning 'little tough guy' — serves in the Brazilian Navy's special operations forces and holds a BJJ black belt. A younger brother is likewise a BJJ black belt and competed professionally for ONE FC.

Burns's early BJJ education was shaped by two key figures: Luis Carlos da Fonseca provided his foundational instruction, followed by Ramon Lemos, who remained a central presence in his development. His early competitive career unfolded under the banner of Nova União, where he also received his first exposure to MMA.

In 2007, Burns earned his black belt promotion from Rafael 'Fofitio' — the nickname of Rafael Formiga, a respected figure in Brazilian jiu-jitsu. That same year, Burns relocated to São Paulo to train under Ramon Lemos in a more competitive environment. He trained initially with Brasa before joining the core group that founded Atos Jiu-Jitsu, one of the sport's most decorated academies. His affiliation evolved into Atos Academy, formerly associated with Oriênte Club. Throughout his career, Burns has competed at Lightweight (75kg/167lbs) — the weight class in which he claimed his most celebrated titles.

The 2010 Surge

The 2010 competition season established Burns as one of the most dangerous lightweights in the world. He swept three major titles that year — the Abu Dhabi World Pro, the IBJJF No-Gi World Championships, and the Brazilian National Championships — a haul that announced him as a legitimate force at the sport's highest level.

The Road to 2011 Worlds

Yet it was 2011 that delivered his most iconic moment in gi competition. Before the IBJJF World Championship, Burns traveled through Europe, teaching a seminar in Switzerland before competing in an Italian tournament offering approximately €4,000 to the winner. In that Italian final, he faced Kron Gracie — took him down and came close to passing his guard, but ultimately lost. The defeat stung, and it sharpened his focus heading into Worlds.

At the 2011 IBJJF World Championship, Burns delivered a definitive performance at Lightweight, defeating Lucas Lepri along the way before meeting Kron Gracie again in the final. This time he left no doubt, claiming the gold medal and turning the Italian result on its head. The victory stands as the summit of his sport jiu-jitsu career — a performance combining technical excellence with a personal redemption narrative that made it all the more meaningful.

Brown Belt Foundations

His brown belt years had already hinted at what was coming. Burns finished as runner-up at the IBJJF World Championship in both 2006 and 2007, and claimed a runner-up finish at the Brazilian Nationals in 2007 — a decorated run at the colored belt level that reflected both his talent and his competitive consistency.

A Chance Encounter That Changed Everything

The week of the 2011 IBJJF Worlds produced not only Burns's greatest grappling achievement but also a chance encounter that redirected his career entirely. After defeating Kron Gracie to claim the world title, Burns crossed paths with Vitor Belfort at a sponsor store during the event week. The meeting quickly evolved into something more substantial — Burns rolled with Belfort for nearly two hours, after which Belfort extended an invitation: join his team, help with jiu-jitsu, and learn MMA in return.

Burns captured the dizzying speed of that transition in a phrase he recounted in a 2016 interview with Jiu-Jitsu Style magazine: 'beat Kron on Sunday, met Vitor on Wednesday, moved to Vegas on Monday.' The sequence left little time for second-guessing, and Burns embraced the leap.

Learning the MMA Game

The Belfort mentorship proved formative in ways that extended beyond technique. Training alongside one of MMA's most experienced fighters and working in Belfort's corner during major UFC events gave Burns an education in big-fight atmospheres, adrenaline management, and the discipline of weight cutting — all elements that would define his UFC career. Burns contributed to fight preparation as a coaching presence in Belfort's camp and participated in The Ultimate Fighter Brazil as part of his growing involvement in the MMA world.

Burns eventually relocated to Florida, where he established himself as a lead BJJ instructor with the Sanford MMA/Kill Cliff FC team — building a base that blended elite grappling with full MMA preparation.

ADCC 2015: Bronze and a Hard Lesson

Burns made his first appearance at the ADCC Submission Wrestling World Championship in 2015, competing in the 77kg division. To prepare, he trained for one month alongside Cláudio Calasans in the United States — a focused camp designed to sharpen his no-gi game ahead of the sport's most prestigious submission grappling event.

Reflecting on the tournament in a 2016 interview with Jiu-Jitsu Style, Burns was candid about a critical miscalculation. He described entering his semifinal against Davi Ramos feeling 'too friendly' and overly relaxed — a mental error he believed directly cost him the match. Responding with clinical authority in the third-place match, he defeated Otávio Sousa 6-0 to claim the bronze medal. The self-diagnosis of that Ramos defeat — the danger of being too comfortable before a high-stakes match — became a touchstone of his competitive philosophy.

High-Profile Grappling Appearances

In 2016, Burns stepped onto the Polaris stage to face Garry Tonon at Polaris 4, one of the most anticipated grappling matchups of that year. Tonon caught him with an inside heel hook in one of the few submission losses of Burns's career. He returned the following year with a victory over John Combs in overtime at Submission Underground 4 in 2017, reasserting himself on the submission grappling circuit.

Even as his UFC career grew in prominence, Burns never retreated from the grappling world. In late 2020, he issued a $400,000 'winner takes all' grappling challenge to Nate Diaz under Chael Sonnen's SUG promotion — a bold move that underscored his confidence in his jiu-jitsu and his appetite for high-profile tests outside the cage. In April 2021, he delivered what many considered a genuine upset by defeating Rafael Lovato Jr. at Who's Number One (WNO) by unanimous decision in a no-gi match. Given Lovato's decorated grappling résumé, the win resonated across the community as a clear statement of Burns's continued elite-level relevance on the mats.

The Psychology of Competition

Burns has been unusually candid about the psychology that drives him as a competitor. In a 2016 interview with Jiu-Jitsu Style, he described feeling genuinely uncomfortable being overly friendly with opponents before matches — a preference rooted in his belief that familiarity dulls competitive edge. He drew a contrast between his own approach and fighters like Buchecha and Rodolfo Vieira, whom he noted were more naturally cordial with opponents. His preferred model aligned closer to Rafa Mendes and Cobrinha — respectful and professional, but never warm in a way that softened competitive intent.

The ADCC 2015 semifinal loss to Davi Ramos served as concrete proof of those principles. Burns cited that match as evidence that entering a contest too relaxed — even in a spirit of mutual respect — is a strategic liability. His approach became one of managing emotional state without surrendering the fighting mentality underneath.

Style and Identity

In terms of style, Burns built his game around a finishing-oriented approach in both grappling and MMA. On the feet he pursued knockouts; on the mat, submissions and ground-and-pound. Passive point accumulation held little appeal. He articulated a commitment to maintaining elite jiu-jitsu as the non-negotiable foundation of his game regardless of how deep into MMA his career extended — viewing continued grappling competition as essential to keeping that foundation sharp.

Burns expressed pride in the scope of what he represents — not merely Niterói, not merely Brazil, but the broader jiu-jitsu community as a whole. In his framing, every performance carries a responsibility to the art that shaped him.

Building the Next Generation

Alongside his continued activity as a competitor and UFC fighter, Burns built a substantive coaching career rooted in the same environment where he trains. Serving as a lead BJJ instructor with the Sanford MMA/Kill Cliff FC team in Florida, he works with both professional MMA fighters preparing for high-level bouts and recreational practitioners developing foundational skills.

The 'Burns BJJ' program formalizes that dual focus, creating a structured avenue for practitioners at every level to train under his guidance. The program reflects the philosophy Burns has articulated throughout his career: that elite jiu-jitsu, maintained through serious competition and honest training, serves as the irreplaceable foundation for any grappler — whether their ambitions lie on the sport mats or inside the cage.

Translating Experience Into Coaching

His early coaching work alongside Vitor Belfort during major UFC events informed the way he approaches fighter preparation, particularly around the psychological and logistical pressures that accompany big fights. That experiential education in high-stakes environments — adrenaline management, weight cutting protocols, corner strategy — flows directly into the guidance he offers the fighters he trains.
