Why is it so hard to bench 100?

Like I agree fitness content on social media is very shady with every other teenager having access to tren and what not. But general ga chusina, PPL in the west bench 2 plates (100kg) like it's nothing. From the age of 15 and all. I thought it's just a social media echo chamber effect. But no, I asked my friends in unis around the world, I saw with my own eyes when I went to UK recently how benching 100 isn't a big deal for serious gym goers.

But we rarely see that mana gyms lo or even fitness content on Social media. Infact I've been trying so hard and after 2 years of starting the gym, I'm finally at 90 for 1. But west lo 100 ni rep chestaru, like it's some 80 or something. Inka D1 athletes or something cheppalsina avasaram ledu, they're strong af.

So my genuine question is : how? Is it in the diet? Genetic variation? ( I'm gonna rule this off because we are not a homogeneous society and there's high variance, so we ought to have more strong PPL than the west in general).

Any thoughts Bondhas?
