Greg Aschwanden Biography & Facts

CrossFit is a branded fitness regimen that involves constantly varied functional movements performed at high intensity. The method was developed by Greg Glassman, who founded CrossFit with Lauren Jenai in 2000, with CrossFit its registered trademark. The company forms what has been described as the biggest fitness chain in the world, with around 12,000 affiliated gyms in over 150 countries as of 2022, under half of which are located in the United States. CrossFit is promoted as both a physical exercise philosophy and a competitive fitness sport, incorporating elements from high-intensity interval training, Olympic weightlifting, plyometrics, powerlifting, gymnastics, kettlebell lifting, calisthenics, strongman, and other exercises. CrossFit presents its training program as one that can best prepare its trainees for any physical contingency, preparing them for what may be "unknown" and "unknowable". It is practiced by members in CrossFit-affiliated gyms, and by individuals who complete daily workouts (otherwise known as "WODs" or "Workouts of the Day"). Studies indicate that CrossFit can have positive effects on a number of physical fitness parameters and body composition, as well as on the mental state and social life of its participants. CrossFit, however, has been criticized for causing more injuries than other sporting activities such as weightlifting; although a review article in the Journal of Sports Rehabilitation found that "the risk of injury from participation in CrossFit is comparable to or lower than some common forms of exercise or strength training". Its health benefits and injury rates are determined to be similar to other exercise programs. There are also concerns that its methodology may cause exertional rhabdomyolysis, a possible life-threatening condition also found in other sports, resulting from a breakdown of muscle from extreme exertion. History CrossFit, meaning cross-discipline fitness, was first conceived as a company in 1996 as Cross-Fit. Greg Glassman developed the rudiment of the training regimen starting when he was 16, combining elements of gymnastics, weightlifting, and calisthenics. The first workout he created was called Fran that combined pull-ups and thrusters (a combination of front squat and push press). Greg Glassman and Lauren Jenai incorporated CrossFit, Inc. in 2000. 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. Those who used Glassman's internet postings expressed an interest in officially incorporating his workouts into their training regimen, and the first affiliated gym (known as 'box'), CrossFit North in Seattle, Washington, was then formed in 2002. Glassman 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. The number of CrossFit-affiliated gyms grew quickly: there were 13 gyms in 2005, 8,000 in 2013, and more than 13,000 in 2016. By 2018, there were around 15,500 CrossFit gyms in 162 countries. Its membership worldwide has been estimated to between two and five million. However, the COVID-19 pandemic forced the closure of around 20% of its gyms (around 25% in the US), and disaffiliations due to the Glassman controversy in 2020 further reduced the number of paid affiliations to 9,400 by early 2021. The number has since recovered to around 12,500 including non-paying affiliates (10,800 paying) by early 2022. Strong growth was observed in Europe, with France having the most CrossFit gyms outside of United States. Glassman obtained complete control over the company in 2012 after a divorce with Jenai, who tried to sell her share in the company to an outside party after the divorce settlement, but Glassman bought it with a $16 million loan from Summit Partners. On June 24, 2020, following the outcry after Glassman's comments regarding the murder of George Floyd it was announced that he was selling the company to Eric Roza, former CEO of Datalogix, in partnership with investment firm Berkshire Partners. Roza assumed the role of CEO after the conclusion of the sale in July. In late November, CrossFit announced a building lease for its Boulder headquarters. At the end of 2020, CrossFit became an LLC. Overview CrossFit is a strength, conditioning, and overall fitness program consisting mainly of a mix of aerobic exercise, calisthenics (bodyweight exercises), and Olympic weightlifting. CrossFit, LLC describes its strength and conditioning program as "constantly varied functional movements executed at high intensity across broad time and modal domains." CrossFit aims to develop fitness in what the company deems to be the ten components of physical fitness: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, coordination, agility, balance, accuracy. Usually, the duration and content of each workout is not fixed. Hour-long classes at affiliated gyms, or "boxes," typically include a warm-up, a skill development segment, the high-intensity "Workout of the Day" (or WOD), and a period of individual or group stretching. Some gyms also often have a strength-focused movement prior to the WOD, though CrossFit encourages most athletes to prioritize intensity over supplemental strength training or additional programming. Performance on each WOD is often scored and/or ranked to encourage competition and to track individual progress. Some affiliates offer additional classes, such as Olympic weightlifting, which are not centered on a WOD. CrossFit gyms use equipment from multiple disciplines, including barbells, dumbbells, gymnastics rings, rope climbs, pull-up bars, jump ropes, kettlebells, medicine balls, plyo boxes, resistance bands, rowing machines, and various mats. CrossFit is focused on "constantly varied high-intensity functional movement," drawing on categories and exercises such as calisthenics, Olympic-style weightlifting, powerlifting, strongman-type events, plyometrics, bodyweight exercises, indoor rowing, aerobic exercise, running, and swimming. CrossFit programming is decentralized, but its general methodology is used by thousands of private affiliated gyms, fire departments, law-enforcement agencies, and military organizations, including the Royal Danish Life Guards, as well as by some U.S. and Canadian high school physical education teachers, high school and college sports teams, and the Miami Marlins. A 2014 statistical analysis showed that 50% of CrossFit participants were male and 50% were female. CrossFit's growing interest internationally has created a spike in Olympic weightlifting interest in the United States. Business model There are three main revenue streams for CrossFit: affiliation, education, and sport. CrossFit licenses the CrossFit name to affiliated gyms for an annual....
