Some bodybuilders go viral for a pose. Rubiel Mosquera went viral for a body part. 🇨🇴
His neck and traps are so extreme that fans gave him a monster name before he had ever won a professional show — and that nickname, “Neckzilla,” has followed him all the way to the Mr. Olympia stage. 💪
This is the story of how a freak feature became a real pro career: two wins in eight days in 2025, a debut on bodybuilding’s biggest stage, and then a season lost to surgery. The comeback is now the whole story.
The Neck That Started It All
Bodybuilding judges do not score necks. They score the whole physique — symmetry, size, conditioning and posing.
So why did one man’s neck matter so much? Because Mosquera’s is genuinely unlike anything else on a pro stage: a thick, powerful column rising straight into traps that look armoured from the front. 😄
His neck is widely reported at around 20 inches — but no official measurement has ever been published, so treat that number as reported, not measured on stage.
The nickname did the rest. “Neckzilla” is easy to remember, easy to share, and it turned a Colombian Elite Pro competitor into a global talking point years before the mainstream press caught up.
The believers were not only fans: after Mosquera’s professional debut in November 2023 — a third-place finish at the EVLS Prague Pro behind Samson Dauda and Michal Krizanek — Dauda said on Fouad Abiad’s Bro Chat podcast that every generation needs its “freak,” adding, “I think we just found ours in our generation,” and that Mosquera “has it in spades.” His one caveat was that Krizanek was the more balanced of the two, saying Mosquera’s upper and lower body looked like “two different people.”
From South America to the Elite Pro Stage
Mosquera was born in Colombia in 1995 and started competing in 2018. His sheer size stood out immediately.
In 2019 he won the super-heavyweight class at the IFBB South American Championships, and he went on to win the Elite Pro South American Championships in 2021.
But the Elite Pro road had a ceiling. It did not lead to the Mr. Olympia — and like Michal Krizo before him, Mosquera eventually crossed over to the NPC, the only route to the sport’s biggest stage. 🔄

One Weekend in Prague Changed Everything 🏆
In November 2023, Mosquera travelled to Prague for the EVLS Prague Pro-Amateur — and won it, earning his IFBB Pro League card at 28 years old.
Most new pros wait months for their debut. Mosquera waited about a day. The same weekend he stepped into the EVLS Prague Pro against stars like Samson Dauda, Michal Krizanek and Nathan De Asha.
Nobody expected the rookie to matter. Instead he finished third — a bronze medal in his professional debut, behind Dauda and Krizanek and ahead of De Asha in fourth. 🔥
The sport took notice fast. Kevin Levrone compared Mosquera’s potential to a combination of Victor Richards and Ronnie Coleman — two of the most freakish physiques in history.
The Hard Years: Visas, Sickness and Near Misses
The plan for 2024 was the Arnold Classic — but visa issues forced Mosquera to withdraw before the show, a decision he announced himself to his followers.
His only pro contest of 2024 was the Dubai Pro, where he placed fourth behind winner Behrooz Tabani, William Bonac and Nathan De Asha.
Afterwards he explained on Instagram Live that he had been sick for a week before the show and on medication — context that made fourth place in that line-up look rather better. 🩺
He opened 2025 with sixth place at the Dubai Pro, again won by Tabani. The conditioning was not quite there — but the adjustments came quickly.
2025: Two Wins in Eight Days — and an Olympia Debut 🥇
On June 28 in Milan, Mosquera won the Flex Weekend Italy Pro, beating Andrea Presti — his first professional victory, and with it his first Mr. Olympia qualification.
One week later he did it again, winning the Mr. Big Evolution Pro in Portugal ahead of Bruno Oliveira Santos and defending champion Nathan De Asha. Two wins in eight days. 🏆
His US visa was secured that August, and in October 2025 he made his Mr. Olympia debut in Las Vegas. In one of the deepest Open line-ups ever assembled, the rookie placed 15th.
Let us be plain about what he has not done yet: Mosquera has no Mr. Olympia title, no Arnold Classic win, and no pro win before those two victories in the summer of 2025. The 15th-place Olympia debut was a foothold, not a coronation.
Training and Nutrition: Built, Not Born Overnight
The neck gets the headlines, but the rest of the package had to be built to pro standard — legs, back and chest included.
Mosquera’s training mixes isolated exercises at higher repetitions with heavy lifting at fewer repetitions per set, keeping muscle activation high across the week.
Contest preparation is where the discipline bites: refined white bread goes, protein from varied sources takes priority, and carbohydrates, sweets and cereals are cut back hard.
That approach is how a viral physique became a conditioned one — the difference between his early Elite Pro look and the leaner version that won in Milan is visible to anyone comparing the two.
Rubiel Mosquera in 2026: Surgery, a Lost Season and the 2027 Target
The follow-up season never happened. Mosquera underwent hernia surgery and spent months away from normal training while he recovered.
His team had initially prepared for a 2026 return after he resumed training in Spain. In the end, they decided a full Olympia qualification push was not the right move at this stage of his recovery.
So Mosquera skipped the entire 2026 season and did not compete at the 2026 Mr. Olympia. His coach confirmed the priority is rebuilding the physique rather than rushing back. 🛠️
Reports during his recovery put him at around 143 kg (315 lb) in the off-season, with the legs as monstrous as ever. The target now is a full comeback in 2027.
That is the same arc other comeback stories on this site have followed — hype, then results, then a break. Vitaliy Ugolnikov’s 2026 break shows how a year away can reset a career rather than end it, and Neckzilla’s camp is betting on the same.
