Simon Costa @simoncostta_

Argentina just flexed, and we felt it from here. Simon Costa is the online coach and freelance model who makes “building muscle” sound like a full-time flirt. He helps guys add size and confidence, and honestly, after one look at his feed, you will understand why they keep coming back. He is handsome, he is humble about it, and we are not at all okay.

Simon Costa, the muscle-building coach from Buenos Aires

Based in Buenos Aires, Simon built his brand on one simple promise: help guys build muscle and confidence. His bio says it plainly, “online trainer, I help guys build muscle and confidence,” and he delivers with the kind of consistency that makes you want to sign up for whatever he is selling. With nearly 200K followers, he is the personal trainer your gym selfie has been waiting for.

Built like a dream, 1.85m of it

Here is where things get interesting. Simon stands 1.85m tall and carries 92kg of what can only be described as very good decisions. He is in a bulking era and the results are, frankly, rude. His posing videos rack up thousands of likes for a reason, and that reason is the way he makes a gym mirror look like a work of art. He is the model who turned “fitness content” into a spectator sport.

More than just a pretty chest

What makes Simon stand out is that he actually coaches. He is an online trainer who helps regular guys build the same kind of physique, minus the genetics. Between the gym selfies and the posing reels, he drops real coaching content for the guys trying to level up. Sponsor-backed, coach-approved, and genuinely helpful, he is proof that a hunk can have a brain and a bicep routine.
