Rubiel Mosquera, also known as ‘Neckzilla,’ hails from Colombia and boasts the title of an IFBB Elite Pro bodybuilder. His claim to fame lies in the remarkable size of his neck, measuring an impressive 20 inches in circumference.
While Mosquera possesses an overall impressive physique, it’s his neck that truly sets him apart and has earned him the affectionate nickname, Neckzilla.

Meet “Neckzilla” in Bodybuilding
While he may not officially hold the record for the thickest neck in bodybuilding, many believe he possesses the most muscular neck in the sport. Viewed from certain angles, it almost appears as if his trapezius muscles extend all the way up to his jawline.
However, it’s his neck that is undeniably more muscular than most. In fact, some bodybuilding enthusiasts have expressed concerns that the sheer size of Neckzilla’s neck might distract judges at competitions, causing them to overlook some of his other physical attributes.
Balanced Approach to Bodybuilding
One might assume that Mosquera dedicates extra time and effort to sculpt his impressive neck, but he asserts that he trains all his muscle groups equally, adhering to the principles of a well-rounded bodybuilder.
Despite not focusing extensively on specific training, this young bodybuilder is fully aware of his distinctive feature and proudly showcases it on social media.
For instance, he once took to Instagram to measure his neck’s circumference, revealing a jaw-dropping 52 cm (40.2mm), a dimension that stands in stark contrast to the average person.
Neckzilla primarily competes in national and regional bodybuilding competitions, where he has shown promising results thus far.
