What Is CrossFit?

CrossFit is a trademarked training and competition system that combines functional movements, high intensity and constant variety. Its goal is broad fitness that carries over into everyday life, including endurance, strength, mobility, speed and coordination.

History and Development

Developed by Greg Glassman in the 1990s; CrossFit, Inc. was established around 2000, with the first “box” in Santa Cruz, California.
From 2005, the affiliate model supported rapid growth to thousands of locations worldwide.
The CrossFit Games have been the sport’s flagship international competition since 2007.

How It Compares

HYROX: less standardized, with more variety and an element of surprise.

iF3: a commercial brand rather than a governing federation.
GRID: individual and team competitions testing all-round fitness rather than sprint races between teams of specialists.
