CrossFit

Trevor L Taylor, a former Division I athlete who went on to Taekwondo, competitive weightlifting and road cycling, is now a CrossFit athlete, and CrossFit is the training system and gym brand that grew from a single website into an international network. The company describes its method as constantly varied functional movements performed at relative intensity¹, delivered with coaching in a group setting. Its history includes rapid growth, a competitive sport, ownership upheaval and a persistent argument about safety, and each of those threads carries lessons beyond the gym.

From a website workout to an affiliate network

Greg Glassman, a personal trainer and former gymnast, founded CrossFit in the mid 1990s, according to The New York Times², with an approach far removed from the bench presses and dumbbell curls that filled gyms at the time. The early following gathered online. A Times report from 2005³ described thousands of people logging on to CrossFit.com for a daily workout that skipped weight machines in favor of short, intense mixes of gymnastics, track and field skills and lifting, with very little rest between movements and heavy emphasis on speed and the weight moved.

The business grew through licensing rather than ownership. The trade site Morning Chalk Up⁴ traces the first affiliate gym to Santa Cruz, California, in 2001, the fifth to 2004 and the ten thousandth to London on June 24, 2014. ESPN reported⁵ that the network went from 8,000 to 10,000 affiliates in a few months that year, and that a weekend seminar, an essay and an annual fee were all it took to use the name. Two years later CNBC counted⁶ 13,000 gyms in more than 120 countries, noting that affiliates paid a fee for the name and very little else was required of them. Fees were also locked at the level a gym paid when it joined, so Glassman told CNBC that some early affiliates still paid only $500 a year. The arrangement made opening a gym cheap and fast, and it meant the brand’s reach grew far faster than any central staff could have managed.

The model scaled fast and proved fragile. In The New Yorker⁷, Matt Hart profiled Eric Roza, who took over as owner and chief executive after the brand was nearly broken by the pandemic and by accusations of racism against its founder. Hart reported that 20 percent of affiliate gyms closed during the pandemic, and that the company depended on surviving gyms continuing to pay their fees.

The method: varied, functional and measured

A typical class combines strength work, conditioning and gymnastics in one session. Movements are chosen because they resemble things people do outside a gym, such as lifting from the floor, pressing overhead, squatting, climbing and running. Workouts change from day to day, so that the body is tested across many demands rather than adapted to one. Intensity is relative: a beginner and a competitor follow the same pattern at very different loads and speeds. Many movements come from Olympic weightlifting and gymnastics, which is one reason coaching quality matters so much. Good coaches scale each workout, reducing the load, shortening the distance or substituting an easier version of a gymnastic skill, so that the same session can serve a newcomer and a veteran. The community element matters as well. Classes are small, members train together at fixed times and the social pressure of a shared clock keeps people returning. The New Yorker observed that many members embrace a narrative of redemption through physical suffering, which helps explain both the loyalty and the risk.

The most distinctive habit is measurement. Each workout produces a time, a number of rounds or a load, and many gyms write the results on a whiteboard. That turns every session into a data point that can be compared against the last attempt, which is the same logic as an athlete’s training log. Constant variety, however, makes classic periodization harder to apply, and critics have long argued that random programming leaves gaps that planned cycles would close.

Safety, scrutiny and the business lessons

Injury has shadowed the method from the start. The 2005 Times piece opened with a police tactical officer who developed rhabdomyolysis, a dangerous breakdown of muscle tissue, after his first session and spent six days in intensive care, and it quoted exercise experts troubled by the lack of guidance for beginners. In Outside⁸, a 2013 feature described a growing list of participants with slipped disks, torn rotator cuffs and knee tendinopathy, while noting that no professional association tracked injury rates. ESPN’s reporting a year later added the worries of clinicians who treat athletes: that so many new gyms could not all have qualified trainers for such intense work, and that racing the clock for as many repetitions as possible invited poor form.

The research picture is more measured than the headlines. A review in the Journal of Sport Rehabilitation⁹ found three cohort studies in which injury rates in CrossFit were comparable to or lower than those in Olympic weightlifting, distance running, track and field, rugby and gymnastics. Shoulder injuries appeared fairly common, injuries were more likely when supervision was missing, and the authors cautioned that the underlying studies lacked randomization and controls.

The competitive side faced its own crisis. At the CrossFit Games in Texas, the Serbian athlete Lazar Dukic, 28, died during an open water swim¹⁰ that followed a 3.5 mile run, the BBC reported. The Times noted that it was the first death in the 17 year history of the Games and that it revived long standing questions about safety in both the workouts and the sport.

For anyone running a business, CrossFit is a case study in licensing. A low cost affiliate model built a global brand with little capital, yet it left quality control to thousands of independent owners and tied every one of them to decisions made at the top. When the founder’s conduct became a public issue, independent owners who had never met him carried the cost in their own neighborhoods. A business that grows through partners inherits their quality and lends them its reputation, in both directions. In the gym, the lesson is the one the injury research keeps returning to: a scoreboard rewards effort, and only good coaching and supervision make that effort safe to repeat.
