There's a hugely noticeable difference between the physiques of the WWE guys and guys in TNA/LU as well. People wonder what happened to Chris Harris that caused him to blow up years back- I think we can take a very good guess.The "bodybuilder" era is over. The wrestlers they have now have bodybuilder physiques, but they train Olympic lifts and Crossfit for explosiveness, agility, and viable strength rather than just training to look good like the Hogan era. Pro wrestling matches are athletic as fuck right now.
The guys in WWE now look like real people/athletes, it's almost closer to the '70s look.
