As well, the US Marine Corps (USMC) developed an exercise program called “High Intensity Tactical Training” (HITT) which has many similarities to CrossFit 5.
Participants in SEALFIT can test their readiness in “Kokoro Camp”, a three day event modeled after the US Navy SEAL Hell Week. There is even a specially tailored version of CrossFit called SEALFIT, which was originally conceived to assist special operations candidates to successfully complete Navy SEAL training 4. For instance, there are currently over 250 registered CrossFit affiliate gyms on United States (US) military installations 3. The popularity of CrossFit is particularly noticeable among personnel in law enforcement, fire and rescue, and military units. Arguably the most popular exemplar of high intensity exercise programs is CrossFit, which describes its methodology as “constantly varied functional movements performed at relatively high intensity” 2. In a recent survey of its worldwide membership, the American College of Sports Medicine (ACSM) found that high intensity exercise methods were the leading trend in the fitness industry 1.
