CrossFit is a strength and conditioning fitness methodology. Its stated goal is to create "the quintessential athlete, equal parts gymnast, Olympic weightlifter and sprinter."[1] Crossfit promotes broad and general overall physical fitness. It is not sport-specific. CrossFit features varied workouts based on functional movement performed at high intensity. Workouts are brief (often 20 minutes or less) and do not use weight machines.[2] Recently, concerns have been raised that CrossFit can cause injury or death from rhabdomyolysis.[3]

Description

CrossFit maintains that proficiency is required in each of 10 fitness domains: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination, and accuracy.[1] CrossFit uses free weights, kettlebells, gymnastics rings, pull-up bars and many calisthenics exercises. CrossFit may call on athletes to skip, run, row, climb ropes, jump up on boxes, flip giant tires, and carry odd objects. They can also squat and throw medicine balls against walls.

CrossFit workouts typically call for athletes to work hard and fast, often with no rest. Many CrossFit gyms use scoring and ranking systems, transforming workouts into sport. Many CrossFit athletes and trainers see themselves as part of a contrarian insurgent movement that questions conventional fitness wisdom.[2][4]

The CrossFit program has been adapted for various client groups. Adaptations include: CrossFit for Kids, CrossFit for Seniors, CrossFit for Endurance Athletes, CrossFit for Soldiers in Austere Environments, CrossFit for Combat Athletes, CrossFit in the Park, and CrossFit Commandos. Most CrossFit gyms also offer "Boot Camp" or "Elements of CrossFit" introductory classes for beginners.[5]

History and growth

CrossFit was created by Greg Glassman, a former gymnast, in the 1970s. For many years the program existed only in a single gym in Glassman's garage in Santa Cruz, California. Glassman launched a website at crossfit.com in 2001 to spread word of his program. CrossFit has grown to an international movement, fueled by an open source and virtual community model.[6] Much of CrossFit's intellectual property, including exercise demo videos, is freely available on its website. There are now more than 550 CrossFit-affiliated gyms worldwide.[7] The affiliate model rejects franchising, requires few start up expenditures, and allows for a diversity of approach. CrossFit headquarters certifies CrossFit trainers and publishes "The CrossFit Journal". According to Canada's Business News Network, CrossFit is "one of the fastest growing fitness movements on the planet."[8]

Some Crossfit athletes perform the "Workout of the Day" posted at the CrossFit website and never visit a CrossFit gym. Others formulate their own workouts based on CrossFit's principles.[citation needed]

In 2007, the United States Marine Corps began a shift in its physical training program. The emphasis is moving away from aerobic training and toward more combat-oriented "functional fitness training" [9] by incorporating CrossFit principles. Many U.S. and Canadian police and fire departments, U.S. Army Special Forces and the Canadian Forces now base some of their physical training on CrossFit principles.[10][11]

CrossFit is also being adopted by a growing number of high school and college sports teams. [12]

Criticism

CrossFit critics include writers,[1][7] fitness professionals[2][6] and a senior officer who commands the U.S. Navy’s Center for Personal and Professional Development.[3] They say Crossfit workouts are so intense that participants risk injury or even death from rhabdomyolysis. At least one CrossFit trainer has been the target of a lawsuit.[3] One writer referred to CrossFit's "cult-like vibe."[7]

CrossFit responds by citing an essential element of its methodology: workouts should always be individually scaled and varied. Critics also fault CrossFit's lax trainer certifcation standards and high participant drop out rate (up to 80% at Glassman's Santa Cruz gym).[2] CrossFit responds that its high intensity and competitive atmosphere are not for everyone. CrossFit says the drop out rate is also high at conventional gyms — where many clients rely on machines, record few performance gains, and pay in advance for annual memberships they quickly abandon.

Mr. Glassman is also known for being a giant bully. Glassman threatens people into what he wants, if he doesn't like what you have or wants something that you have then he will then threaten you until he gets what he wants. He has numerous records of threating people, and hurting people if he doesn't get what he wants. Mr. Glassman well be taken to court shortly for threats he has made to a ohio family.
