CrossFit is a branded fitness regimen made by Greg Glassman and is a registered trademark of CrossFit, Inc. founded by Greg Glassman and Lauren Jenai in 2000. Promoted as a physical exercise philosophy and also as a competitive fitness sport, CrossFit exercises combine elements of high intensity interval training, Olympic weight lifting, plyometrics, powerlifting, gymnastics, girevoy sports, gymnastics , strong, and other exercises. It is practiced by members of over 13,000 affiliated gyms, roughly half of them located in the United States, and by individuals who complete daily practice (otherwise known as "WOD" or "today's exercise"). CrossFit has been a controversy for allegedly causing people to suffer unnecessary injuries and rhabdomyolysis during activity, a condition in which muscle tissue dies.

Overview
CrossFit is a strength and conditioning program that mainly consists of a mixture of aerobic exercise, gymnastics (weight training), and Olympic weight lifting. CrossFit, Inc. describes its strength and conditioning program as "constantly varying functional movements carried out at high intensity across time and capital domains", with the stated goal of improving fitness, defined as "working capacity across broad time and capital domains." Classes for hours in the affiliated gym, or "box", usually include warming, skill development segments, "high intensity day exercises" (or WOD), and stretching periods of individuals or groups. Some fitness centers also often have movements that focus on strength before WOD. Performance on every WOD is often rated and/or ranked to encourage competition and to track individual progress. Some affiliates offer additional classes, such as Olympic weight lifting, which are not centered around WOD.
CrossFit fitness center uses equipment from a variety of disciplines, including barbells, dumbbells, gymnastics, pull-up bar, jumping rope, kettlebell, medicine ball, plyo box, resistance band, rowing machine and various mats. CrossFit focuses on "continuous motion, high intensity, functionality," drawing on categories and exercises like this: gymnastics, Olympic weight lifting, powerlifting, Strongman type events, plyometrics, weight training, indoor rowing, aerobic exercise , running, and swimming.
CrossFit programming is decentralized but the methodology is commonly used by thousands of private affiliated fitness centers, fire departments, law enforcement agencies, and military organizations including the Danish Royal Guard, as well as by some US and Canadian high school physical education teachers, high schools. and college sports teams, and Miami Marlins.
"CrossFit is not a special fitness program, but a deliberate effort to optimize physical competence in each of the 10 recognized fitness domains," says founder Greg Glassman in the Foundation document. These domains are: cardiovascular and respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, and accuracy.
CrossFit attracts both men and women and the statistical analysis of 2014 shows that CrossFit participants are both 50% male and 50% female.
CrossFit's increasing international interest has also created a spike in interest in Olympic weight lifting in the United States.
Business model
CrossFit, Inc. licensed the CrossFit name to the fitness center for an annual fee and certified the trainer. In addition to the standard two-day "Standard Level Trainer" course, special seminars include gymnastics, Olympic weight lifting, weight lifting, strong man, running and endurance, rowing, kettlebell, mobility and recovery, CrossFit Kids, CrossFit Football, and self defense and conspicuous. Other special adaptations include programs for pregnant women, elderly, and special military operations candidates. Affiliates develop their own programming, pricing, and learning methods. Many athletes and coaches see themselves as part of the resistance movement, insurgents who question conventional fitness wisdom; in addition to performing the prescribed exercise, they follow the CrossFit nutritional recommendation (adopting paleo and/or zone diet).
CrossFit takes advantage of the virtual community Internet model. The company says this de-centralization approach shares some common features with open source software projects and enables best practices to emerge from a variety of approaches, a disagreement that is disputed by some competitors and former affiliates.
Effectiveness
The benefits of Crossfit's claimed for physical performance are not proven by a body of good medical proof.
CrossFit Game
The "CrossFit Games", directed by Dave Castro, has been held every summer since 2007. Athletes at the Olympics are competing in the exercises they studied just hours before, sometimes including a surprise element that is not part of a typical CrossFit regimen. Examples of the past include harsh water-swimming, softball throwing, and climbing pegboard. The Olympics are laid out as a place to determine "Fittest on Earth," where competitors have to be "ready for anything."
In 2011, the Olympic Games adopted an online qualification format, facilitating participation by athletes around the world. During "CrossFit Open" for 5 weeks, one new exercise is released every week. Athletes have a few days to complete the exercises and submit their scores online, either with video or validation by CrossFit affiliates. Since Open is available to every level of athlete, many affiliates encourage member participation and the number of participants worldwide can reach hundreds of thousands.
Top CrossFit Open players for individuals and teams in each region progress to regional events, held over the next two months. The Olympics includes divisions for individuals of each gender, joint team, and a number of Master and Adolescent age groups.
Certification
To become a certified CrossFit trainer, one must go through a series of four levels of training. However, not all CrossFit gyms require their trainers to have all four levels of training - most gyms require at least one certification level. Level one (CF-L1) is the level of introduction, in which participants attend group weekend classes and talk about the basic methodology and fundamentals of CrossFit, and learn how to do their own classes. They discussed the technique and how to adapt it to those who can not do it. Throughout the Level One training course, one must be confident in doing the class, appropriate training scales for athletes, and maintaining CrossFit by default. At the second level, training goes deeper into the mechanism of movement and how to become a leader and communicate with other students. At the two-course level, participants learn about athletic capacity and are evaluated as trainers in groups. To obtain a level three certificate, the trainer must complete 1,500 hours of active fitness training along with being a certified CPR. To get a level four certificate, the highest level currently recognized by CrossFit, Inc., the coach should take several years as a level three and pass the test.
Criticism
Injuries
The risk of injury associated with CrossFit training has been a controversial question since the popularity of the program began to rise in the early 2000s. Critics accuse CrossFit, Inc. using dangerous movements, inappropriate levels of intensity, and allowing unqualified individuals to become CrossFit Trainers.
In response to this criticism, CrossFit, Inc. claims, "CrossFit is relatively safe even when done with a bad technique, but it is safer and more effective when done with a good technique." CrossFit, Inc. also claims the risk of injury can be reduced by scaling and modifying the exercise well, a concept taught on its website and at CrossFit Level 1 Trainer Course.
CrossFit, Inc. supported this position by citing three CrossFit participant academic surveys. The survey calculated an injury rate between 2.4 and 3.1 injuries per 1000 hours of training, which according to CrossFit is consistent with or below the level of injury found in "general fitness training."
A study published in the Journal of Strength and Conditioning Research entitled "Crossfit High intensity strength training enhances maximum aerobic fitness and body composition" followed by 54 participants during 10 weeks of CrossFit training. The study says that "... a large percentage of our subjects (16%) did not complete the training program and returned for further testing." The authors say, "This might question the risk-benefit ratio for such extreme training programs..." In 2014, CrossFit, Inc. filed a lawsuit against the National Strength and Tightening Association to publicize the research, alleging that the data was false and "intended to scare off participants from CrossFit." NSCA denies allegations of CrossFit, Inc. but has issued a confession that recognizes the injury data is not true. In September 2016, the District Court ruled in favor of CrossFit Inc. claims. that the injury data was found to be false, but not that the NSCA was commercially motivated or that the publication of the study was libelous because the NSCA no longer stands behind the research. In February 2017, CrossFit filed sanctions against the NSCA after one of the NSCA witnesses confessed to falsifying statements during the deposition. In May 2017, the Court issued 17 sanctions issues against the NSCA, writing that the organization does have a commercial motive for falsifying data, has deliberately deliberated false data to belittle CrossFit, and has misled the public with their erratum. CrossFit was awarded $ 74,000 in legal fees as well as allowances to continue to investigate the NSCA. If a neutral party analysis of the NSCA server appears further errors, CrossFit may re-submit the modified complaint for further sanctions and compensation for lost income.
Expansional Rhabdomyolysis
The relationship between CrossFit and rhabdomyolysis during activity has been the subject of controversy for the company. Some medical experts have confirmed that the CrossFit methodology and environment created by CrossFit trainers puts athletes at high risk for developing rhabdomyolysis.
A man successfully sued his non-certified CrossFit trainer and received $ 300,000 in damages after he suffered rhabdomyolysis after a CrossFit exercise on December 11, 2005, at Manassas World Gym in Manassas, Virginia, under the supervision of the trainer. CrossFit, Inc. not registered as a defendant in the lawsuit.
CrossFit, Inc. does not argue that its methodology has the potential to cause rhabdomyolysis. The company states that occupational rhabdomyolysis can be found in a variety of sports and training populations and argues that its critics have combined high-awareness of CrossFit about high-risk rhabdomyolysis. A CrossFit spokeswoman stated that "ESPN's report of 53 deaths in US triathlons from 2007 to 2013 should put the issue to rest."
Since May 2005, CrossFit, Inc. has published several articles on rhabdomyolysis at the company CrossFit Journal. Three articles are included in the CrossFit Manual provided for all potential trainers.
CrossFit, Inc. has also been criticized for having an "arrogant" attitude to rhabdomyolysis by promoting a character known as "Uncle Rhabdo" (a dying cartoon clown dramatically - connected to a dialysis machine, with his kidneys and intestines falling to the floor).
In response to this critique, Greg Glassman has stated "We introduce (Uncle) Rhabdo because we are honest and believe that full-risk disclosure is the only ethical thing to do."
Social media presence
CrossFit, Inc. has been widely criticized and praised for its unorthodox approach to social media. This approach includes publishing articles and tweets on non-fitness topics (including politics, philosophy, and poetry) and directly interacting with other social media users and critiques of corporate programs. In one instance, Twitter account CrossFit, Inc. posted a famous illustration of Coke ads, with "Open Happiness" replaced with "Open Diabetes". The picture was paired with a quote from CrossFit CEO, Greg Glassman which reads: "Make sure you pour some for your dead homies." The controversy followed after singer Nick Jonas responded to the tweet, calling CrossFit, Inc. comments "does not matter". The company defended his tweets, stating that "Interesting statistical evidence supports CrossFit, Inc.'s campaign to prevent diabetes by raising awareness about the cause." When ABC News asked Greg Glassman to comment on the exchange, he replied "Fuck Nick Jonas This is about the specter of Type 2 Diabetes and its main cause: Sponsors, Coca-Cola, is a significant contributor to the diabetes epidemic both with product spending and 'marketing'."
