I think each generation tries to be more "real" than the previous generation. At first social media allowed us to express "who we really are" by providing us tools to present "who we think we are". This was more "real" in contrast to the suit & tie professional persona many were shoehorned into. (Which was more "real" in contrast to traditional work-husband/housewife roles, since it was theoretically gender-blind) Now social media personas feel too "fake". Being physically fit in the real world is one of the only hard-to-fake ways to stand out as "special" now.
