The genesis of the shot put can be traced to pre-historic competitions with rocks:<ref>[http://www.britannica.com/EBchecked/topic/541863/shot-put Shot put] {{Webarchive|url=https://web.archive.org/web/20100206011856/http://www.britannica.com/EBchecked/topic/541863/shot-put |date=6 February 2010 }}.

This was amended to a circle area with a seven-foot diameter in 1906, and the weight of the shot was standardised to {{convert|16|lb|kg}}. Throwing technique was also refined over this period, with bent arm throws being banned as they were deemed too dangerous and the side-step and throw technique arising in the United States in 1876.<ref name=IAAFSP />

The shot put has been an Olympic sport for men since 1896 and a women's competition using a {{convert|4|kg|lb|abbr=on}} shot was added in 1948. Further throwing techniques have arisen since the post-war era: in the 1950s [[Parry O'Brien]] popularised the 180 degree turn and throw technique commonly known as the "glide", breaking the world record 17 times along the way, while [[Aleksandr Baryshnikov]] and [[Brian Oldfield]] introduced the "spin" or rotational technique in 1976.<ref name=IAAFSP /><ref>{{cite web |last=Rosenbaum |first=Mike |url=http://trackandfield.about.com/od/shotput/p/introshotput.htm |title=Introduction to Shot Put |archive-url=https://web.archive.org/web/20090527132035/http://trackandfield.about.com/od/shotput/p/introshotput.htm |archive-date=27 May 2009 |url-status=usurped |website=About |access-date=11 May 2010}}</ref>
