We all have them.

That friend from school that works out constantly. The best friend who always checks in after their run in Marley park. We, the black sheep of the #IrishFitFam are forced to look on in awe, self-loathing and jealousy and wonder when our mortal fitness efforts and attempts at only eating avocado will pay off. But fret not comrades, it turns out that those greased up ripped acquaintances actually have psychological problems. According to researchers from the Brunel University in London, people who document their gym activities tend to be narcissists. Researchers found that they post updates to boast about how much time they spend trying to look good and their goal is to earn Facebook likes and attention. "Narcissists more frequently updated about their achievements, which was motivated by their need for attention and validation from the Facebook community", the study finds. The study examined different personality traits and decoded why certain people write about certain topics. The researchers concluded that this information is important. “These results help to explain why some Facebook friends write status updates about the party they went to on the weekend whereas others write about a book they just read or about their job promotion. It is important to understand why people write about certain topics on Facebook insofar as the response they receive may be socially rewarding or exclusionary. Greater awareness of how one’s status updates might be perceived by friends could help people to avoid topics that annoy more than they entertain.”
