Not really.  Think about evolving on all fours while trying to outrun, out
climb or out swim hungry predators.  These are the exact muscles you would
maximize.  The glutes pull our hip joints back to provide thrust with our
legs.  The pecs pull our shoulder joints back to provide thrust with our
arms.  Those with the largest glutes and pecs escaped predators more often.
This is a simply a matter of speed provided by the larger muscles.  Sexual
attraction to these muscles probably evolved as a secondary trait, just as
attraction to symmetrical, healthy, brightly-colored, similar-looking mates
did.
