2. Club Swinging
The 1904 St. Louis edition of the Olympic Games was a bit controversial, but not because club swinging was included among the sports.
The wooden club is the modern version of the club our ancestors used to settle cave feuds. At this point you are probably eager to know the rules of games. Contrary to a popular myth (most likely influenced by circus acts), the clubs where not thrown in the air, but swung in a way that would impress the judges.
A small version of the sport survived in rhythmic gymnastics, although the clubs are much smaller and lighter, fitted for the small bodies of prepubescent gymnasts.
