They opened a gym in Santa Cruz, California in 2001 and posted their workouts on the Internet for their clients, and these workouts were then quickly adopted by individuals in the police, military, firefighting services. The first affiliated gym (known as ‘box’) to form was CrossFit North in Seattle, Washington when Glassman’s internet postings were used by those who wanted to officially incorporate his workouts into their training regimen in 2002. Glassman then began to develop a curriculum to train and certify coaches and gym owners using his methodology. Coaches associated with CrossFit include Louie Simmons, John Welbourn, and Bob Harper.
