Many famous bodybuilders posed naked during their careers as musclemen. Arnold Schwarzenegger is undoubtedly the most famous bodybuilder of all time though the pics of the nude bodybuilder are not all that well known.
Cur or Uncut? A full-frontal nude pic of the young bodybuilder taken in Europe shows him with a foreskin. However, a pic taken later in the US seems to reveal a circumcised dick. Arnold said in an interview that he underwent circumcision after moving to the States on the recommendation of a trainer.
