Planet Fitness is a fitness center brand that started in Dover, New Hampshire in 1992 and has grown into one of the largest and fastest-growing franchisors of fitness clubs in the world[4][5]. The company was founded by two brothers who bought a struggling gym and transformed it into a welcoming, affordable fitness experience for everyday people[6]. Over the years, Planet Fitness has become known for its “Judgement Free Zone” approach, making fitness accessible and comfortable for a broad range of members.

As of December 2025, Planet Fitness operates about 2,795 clubs across all 50 states, the District of Columbia, Puerto Rico, Canada, Panama, Mexico, Australia, and Spain, with more than 20 million members. The brand’s expansion has been driven by a franchise model, allowing independent operators to open and manage clubs while maintaining consistent standards and service quality[3]. Most new locations are opened by franchisees, which has helped Planet Fitness scale rapidly while keeping a local presence in communities.

Planet Fitness has evolved by focusing on affordability, inclusivity, and a non-intimidating environment, which sets it apart from traditional gyms[6]. The company’s growth posture is aggressive, with hundreds of new clubs opening each year, and it continues to expand into new markets and countries[3]. Its long operating history and strong brand recognition make it a reliable tenant for landlords and developers, especially in retail and mixed-use environments where daily traffic and repeat visits are valued[3].
