Guilherme Lambertucci

Guilherme Lambertucci was born on July 2, 1997, in Belo Horizonte, the capital of Minas Gerais in southeastern Brazil. From an early age, his natural size and tendency to gain weight led his family to enroll him in judo at age 6 — not as a competitive pursuit, but as a structured outlet for his physical development.

What began as a practical decision quickly ignited a genuine passion. The young Lambertucci dove into youth judo competition, accumulating experience across kids' divisions and earning a "Mineiro" title — the Minas Gerais State Championship — an early achievement that revealed sharp competitive instincts. The discipline and grappling fundamentals he built through judo would prove foundational to the athlete he would later become.

In 2010, a family relocation forced the then-12-year-old to leave judo behind, with no accessible clubs near his new home. Rather than stepping away from martial arts entirely, Lambertucci found a new path at the Magrelo Fight Academy, where coach Fábio Costa introduced him to Brazilian Jiu-Jitsu. The transition from judo to BJJ was a natural fit — the grappling instincts he had sharpened on the judo mat gave him a tangible head start on the mats.

Lambertucci's development as a BJJ practitioner unfolded gradually but with clear intent across more than a decade of training. After approximately five years under coach Fábio Costa at the Magrelo Fight Academy, he recognized that his competitive ambitions demanded a more rigorous environment. He made the move to Gracie Barra in Belo Horizonte as a purple belt — a significant step up in both the quality of training partners and the depth of competitive preparation available to him.

It was his admiration for Felipe Pena — widely known by his nickname "Preguiça" and one of the sport's most decorated competitors — that ultimately shaped the direction of his career. In January 2016, Lambertucci joined Pena's FP Team, a Gracie Barra-affiliated training group that brought together some of Brazil's most dedicated competitors. The move represented not merely a change of gym, but a wholesale commitment to elite-level jiu-jitsu.

The years that followed brought steady progress and significant adversity in equal measure. Multiple knee injuries disrupted Lambertucci's momentum at critical points in his colored belt career, demanding patience and resilience during extended recoveries. Despite these setbacks, he continued to develop and compete at a high level through the purple and brown belt divisions. After nearly six years of dedicated work under Pena's mentorship, Lambertucci received his black belt on December 17, 2020 — a promotion that acknowledged both his technical maturity and his perseverance through hardship.

Brown Belt Breakthrough

Competing at 100.50 kg / 222.0 lbs, Lambertucci established himself as one of his generation's most formidable super-heavyweights across both the AJP Abu Dhabi Jiu-Jitsu Tour and the IBJJF — the two premier circuits in competitive jiu-jitsu.

His brown belt years produced some of the most telling results of his competitive rise. In 2018, he claimed gold at the CBJJ Brazilian Nationals NOGI, confirming his status as a top domestic prospect. The following year proved to be his most productive season as a brown belt: he captured gold at the 2019 AJP Grand Slam London, earned silver at the 2019 IBJJF European Open, and added another silver at the AJP Abu Dhabi World Pro. That run of results demonstrated his ability to perform consistently across both gi and no-gi formats and on multiple continents — a mark of genuine international caliber.

Black Belt Arrival

The transition to black belt competition brought fresh challenges, but Lambertucci made his presence felt without delay. In 2021, he claimed gold at the 2021 IBJJF South American Championship NOGI in his weight division and captured the AJP Brazilian National Pro title — his first major open titles at the sport's highest level. He also reached the absolute final at the 2021 IBJJF South American Championship NOGI, adding a silver medal in a division that pitted him against competitors from every weight class. The breadth of his podium appearances across multiple years, formats, and belt levels reflects both the durability and competitive range that define his career.

Beyond his results on the competition mat, one of the most revealing episodes in Lambertucci's story is the personal crossroads he faced before fully committing to jiu-jitsu as a profession. At a pivotal point in his young adult life, he had enrolled in law school but found himself deeply disconnected from the direction his academic path implied. He explored other fields of study with equal indifference. By his own account, jiu-jitsu was the only pursuit that genuinely moved him — yet the financial uncertainty of a career in martial arts made the choice far from straightforward.

This period of professional doubt coincided with Lambertucci's conversion to Christianity, and it was within that context that a defining moment occurred. In a state of genuine uncertainty about his future, he prayed for clarity and direction. The following day, at church, a fellow parishioner he had never previously met introduced himself, explained that he was developing a community grappling project, and asked whether Lambertucci — a BJJ athlete by reputation — would be interested in coaching.

Lambertucci took the encounter as a direct answer to a sincere question and made the decision to pursue jiu-jitsu as his career. The episode, which he recounted in his own words, illuminates a dimension of his identity that extends well beyond trophies and podium finishes. His commitment to the sport is not merely athletic — it is grounded in a deeply personal conviction that jiu-jitsu is the path he was meant to follow.
