The company began in 1983 as a one-club operation called 24 Hour Nautilus. Mark Mastrov and Leonard Schlemm began the firm, with Mastrov and Schlemm remaining to continue its expansion.[]

CEO Mark Mastrov hired Mark Golob and Dean Moloney as Vice President of Marketing. Golob created promotional campaigns with Pamela Anderson, Arnold Schwarzenegger and Mike Tyson that increased membership and sales. During Moloney's tenure, he and Mastrov, along with Tom Gergley and Golob, began planning an international chain of health clubs.[] In 1994, 24 Hour Nautilus partnered with McCown De Leeuw and soon thereafter acquired the Southern California-based Family Fitness Centers chain, renaming the company 24 Hour Fitness.[]

Todd Smith and Adam Shaw were responsible for the physical expansion of the company during their initial growth period.

In 2004, 24 Hour Fitness became a sponsor of the 2004-2008 United States Olympic teams. The sponsorship grants memberships to some U.S. Olympic hopefuls and includes upgrades to some U.S. Olympic Training Centers across the country, including renovation of the facility in Colorado Springs, Colorado, in 2004 to be followed by Lake Placid, New York, and Chula Vista, California.

24 Hour Fitness worked with NBC to develop a reality show, The Biggest Loser, which features 12 to 22 overweight contestants competing to lose weight over several million dollars. The show first aired in late 2004.[]

From 2005 to 2008, 24 Hour Fitness co-sponsored the Discovery Channel Pro Cycling Team.[]

24 Hour Fitness formerly had some 15 clubs in Singapore and China. Besides the United States, it had centres in Singapore and Hong Kong, Beijing and Shanghai in China) through its wholly owned subsidiary California Fitness (CalFit). Its European clubs closed in the early 2000s. CalFit has been sold to a Hong Kong company in 2012, providing continuity and retaining the name and memberships without the bad closure experiences of CalWowX, whereby becoming an exclusively US gym chain.[]

Its former affiliate and spinoff California Wow Xperience (CalWowX), a California Fitness offshoot, formerly had member swap agreements with both 24 hour, then only California fitness, and at its height ran gyms located in Bangkok, Chiang Mai and Pattaya in Thailand, including one female-only club. It was also listed on the stock exchange with major Thai corporate partners. CalWowX and CalFit former centers in Korea, Thailand, Malaysia, and Taiwan (10/1/2010) have closed or been sold off, with CalWowX franchised gyms in Korea being abruptly closed on contracted members without reimbursement. Similarly, the CalWowX Thailand was charged with criminal embezzlement by local investment banks before abruptly closing with millions of dollars in debts and angry customers left empty handed who had signed up for lifetime membership.[]

Celebrity Fitness, yet another gym chain with 24 Hour Fitness roots, is headquartered in Jakarta and runs gyms in Indonesia, Malaysia, Singapore and India.[]

Neither CalWowX nor Celebrity Fitness had competed directly with California Fitness.

In August 2012, the owner of 24 Hour Fitness put the 416 location gym chain on the auction block with a price tag reported to have been close to $2 billion.[4] After being courted by various interests for over six months, ultimately in January 2012, the board of directors took 24 Hour Fitness off the market. Offers reportedly fell short of the asking price.[5][6]

In May 2014, Forstmann Little & Co. has reportedly sold 24 Hour Fitness Worldwide Inc. to a group of investors for $1.85 billion to an investment group led by AEA Investors LP and the Ontario Teachers' Pension Plan.[7]

On July 31, 2007, 24 Hour Fitness settled a class-action lawsuit brought against it by 1.8 million current and former members. The plaintiffs claimed damages for the continuation of automatic withdrawals by 24 Hour Fitness long after their monthly memberships were canceled by request.[8][9] In McCardle vs 24 Hour Fitness USA, Inc., the Alameda County Court ruled in favor of the plaintiffs of the class-action lawsuit. In 2010, the court found that 24 Hour Fitness did not act in good faith after denying members who purchased an "All Club" membership access to rebranded locations without charging additional fees not disclosed in the original contract.[10][11]

Six former employees of 24 Hour Fitness filed a separate class-action lawsuit on July 13, 2010. This lawsuit was brought in the State of California pursuant to allegations that 24 Hour Fitness discriminated based on race and gender in their promotion practices. The claimants are either females, minorities, or both.[12][13]
