Rubiel Mosquera, a.k.a. ‘Neckzilla’, is an IFBB Elite Pro bodybuilder from Colombia known primarily for the size of his muscular neck, which reportedly measures 20 inches in circumference.

Rubiel Mosquera has a pretty impressive physique, but just one look at his neck is enough to explain his popular nickname, Neckzilla. It really is something to behold, and while he doesn’t hold the official title of the thickest neck in bodybuilding, there are many who believe he truly has the most muscular neck in the sport. Seen from some angles, it seems like his traps stretch all the way up to his jawline, but it’s actually his neck that is simply a lot more muscular than most. It is so muscular, in fact, that some bodybuilding fans have expressed concerns that the size of Neckzilla’s neck distracts judges at bodybuilding competitions causing them to miss some of his other assets.

You might be tempted to think that Mosquera dedicates a lot more time and attention to his large neck to make it stand out, but the Colombian bodybuilder says he trains all of his muscle groups equally, like any self-respecting bodybuilder.

Although he doesn’t focus too much on his neck when training, the young bodybuilder is fully aware of his main asset and always shows off his neck on social media. For example, he once measured his neck on Instagram to prove that it was thicker than that of rival bodybuilder Larry Wheels. The measuring tape showed over 52 cm in circumference (40.2mm), which is just insane compared to the average person.

Neckzilla competes mostly in national and regional bodybuilding competitions, and so far he has had encouraging results.
