Planet Fitness, one of the largest gym chains in the United States.

Specifically:

• Planet Fitness has over 2,000 locations across the United States as of 2023.
• The company’s main website, PlanetFitness.com, features an active blog section that is regularly updated with new content.
• The Planet Fitness blog covers a variety of fitness, health, and lifestyle topics relevant to their members, such as workout tips, nutrition advice, member success stories, and company news.
• Based on my research, it appears Planet Fitness operates this single, centralized company blog that represents all of their nationwide club locations, rather than individual clubs maintaining their own separate blogs.

So in summary, while I don’t have an exact count, it’s safe to say that all 2,000+ Planet Fitness gym locations in the USA are represented by the single, official Planet Fitness blog hosted on the company’s main website. This allows them to provide consistent, branded content to members across their entire national footprint.
