Colombian bodybuilder Rubiel “Neckzilla” Mosquera is gearing up for his long-awaited debut at the 2025 Mr. Olympia, and anticipation around his appearance is sky-high. Known for his jaw-dropping proportions and dense muscularity, Mosquera has been turning heads throughout the bodybuilding world — including that of legend Milos Sarcev.
As he prepares for the biggest stage in the sport, Mosquera’s sheer size and symmetry have left fans and veterans alike in awe. Sarcev, who has trained and competed alongside some of the greatest athletes in history, recently admitted he was stunned by Mosquera’s unbelievable leg development. During a recent interaction, Sarcev tried to measure the Colombian’s quads with his hands — and it reportedly took four full hand spans to encircle one thigh.
Rubiel Mosquera’s Road to the 2025 Olympia
Mosquera’s journey to this year’s Olympia stage has been far from easy. In August 2025, he shared the news that he had finally completed the lengthy visa process that allows him to compete in the United States. After traveling to Colombia to finalize paperwork, he successfully obtained his visa — a major milestone after previous setbacks.
In 2024, Mosquera was forced to withdraw from the Arnold Classic due to similar visa complications, a huge disappointment for both him and his growing fanbase. Now, with those issues behind him, he’s ready to make his long-awaited Olympia debut and showcase his hard-earned improvements before the sport’s most passionate audience.

From Viral Sensation to Elite Competitor
While his massive neck first drew viral attention, it’s Mosquera’s leg development that truly defines his competitive physique. In 2021, his left thigh measured nearly 32 inches (80.5 cm) — a size that rivals legends like Big Ramy, whose lower-body mass has set the standard in the modern era.
His legs, featuring massive quads, deeply separated hamstrings, and powerful calves, give him one of the most complete lower-body builds among today’s professionals. Combined with his freakish upper body and balanced proportions, Mosquera’s physique has evolved into something both shocking and aesthetically impressive.
From IFBB Elite Pro to Olympia Contender
Like many modern competitors, Mosquera began his professional journey in the IFBB Elite Pro League before transitioning to the NPC, where the path to Olympia qualification runs through the IFBB Pro League. His rise was swift — after earning his Pro Card, he immediately entered the Men’s Open division, the most competitive category in bodybuilding.
Mosquera made an instant impact, stepping onto the stage at the 2023 EVLS Prague Pro just days after turning professional. Despite facing seasoned athletes like Samson Dauda and Michal Krizo, Mosquera placed an impressive third, signaling his potential to become one of the sport’s next breakout stars.
The 2024–2025 Season: Consistency and Growth
In the following season, Mosquera competed three times, steadily improving with each appearance. He began the year with a sixth-place finish at the Dubai Pro, showing flashes of brilliance and undeniable stage presence. His conditioning and size peaked as the season progressed, leading to two major victories — the Flex Weekend Italy Pro and the Mr. Big Evolution Pro — both of which secured his qualification for the 2025 Olympia.
Now, with momentum on his side and his visa hurdles behind him, Rubiel “Neckzilla” Mosquera is ready to test himself against the world’s best. Fans are eager to see whether his combination of extreme muscle mass, striking symmetry, and undeniable charisma can carry him into Olympia’s top ranks — and perhaps even toward the sport’s ultimate crown.
