It's one of those things that varies wildly by artist, although having the same body type doesn't automatically mean the same level of physical power in a superhero world. For instance, Supergirl is generally depicted as petite despite her extreme strength. Of course the double standard is that a superheroine has to have superstrength before artists even consider giving them significant muscular definition, yet the average superhero will automatically be buff regardless of their abilities.
