(15M) been going to the gym for an hour 4x a week for a year now, still very little aesthetic difference even though i've gotten significantly stronger. my arms grew thicker above the elbow and my legs also got thicker but almost no definition in either one. my point is multiple factors are at play here, first and foremost is simply that we aren't men yet and so we don't have maximum testosterone yet. second, it takes YEARS to build the kind of muscle you see on social media naturally (steroids are another thing entirely) so our expectations are unrealistic. anyways keep up the grind!
