Of these federations, the oldest and most prominent is the IPF. It comprises federations from over 100 countries located on six continents. The IPF is the federation responsible for coordinating participation in the World Games, an international event affiliated with the International Olympic Committee. The IPF has many affiliates, one of these being USAPL. Specifically, the USAPL regulates all ages of lifters from the high school level to ages 40+ within the United States. The next-oldest federation is the WPC, formed as the international companion to the APF after its split from the USPF.
