i was fishing years back at a lake near me and saw an asain dude with gigantic calves and quads,not just huge but shredded like a bodybuilder also.found out from his freind who was fishing near me that he just rides a bike everyday for 40 miles.i still dont believe thats all he does,his legs had veins in them and they where sickly huge like really good bodybuilders legs.maybe i dont want to believe it,thats more likely cause i break my ass trying to make leg gains and some guys dont give a shit about that n get huge legs
