Mark Mastrov Opens a $10M Flagship in Summerlin

According to Club Solutions, 24 Hour Fitness founder Mark Mastrov is opening Founders Club by 24 Hour Fitness, a 45,000-square-foot facility at 9200 West Sahara Avenue in the Summerlin area of Las Vegas, with a scheduled opening in early 2027. The club represents a $10 million investment, with more than $1 million allocated to recovery equipment alone. The floor plan dedicates 25,000 square feet to free weights and strength training, including 12 platforms, alongside dedicated classrooms and a recovery room. Mastrov, who founded 24 Hour Fitness in 1983 and has since built gyms across more than 60 countries, describes the project as a deliberate statement about what the next generation of fitness should look like, citing Summerlin’s status as one of the fastest-growing communities in the United States as a key reason for the location.

Why a Single Flagship Club Is a Market Signal Worth Watching

This is not a rollout. It is one building, one location, and a founding operator spending serious capital to make a point about format. The $10 million price tag, including seven figures in recovery equipment, positions Founders Club well above the cost structure of a typical big-box refresh. For operators, the relevant question is what this says about where value is being placed: large open floor space, density of equipment, and recovery infrastructure rather than boutique intimacy or digital add-ons. The Sqwod Deal Tracker shows $347 million in disclosed gym and studio deals tracked since early 2026, across operators including PureGym, FitLab, and others, but most of that activity has involved acquisitions and raises rather than ground-up flagship builds of this scale. What remains unknown is whether Mastrov intends to replicate the Founders Club format across multiple markets or whether this stays a single proof-of-concept site.

A Founder Betting on Substance Over Story

The Sqwod view is that Founders Club is a deliberate counter-argument to the last decade of fitness industry positioning, which leaned heavily on brand aesthetics, community language, and technology. Mastrov is spending the money where members actually spend their time: on the floor, under a barbell, and in a recovery room. That is not a nostalgic move. It is a calculated one, aimed at a customer who has cycled through boutique studios and digital subscriptions and now wants equipment that is available, space that is not crowded, and a facility that takes training seriously. Who wins here is the member who has been underserved by gyms that prioritized look over function. Who loses, if this format proves compelling, is the mid-market operator still running a dated big-box model without the investment to match it. A $10 million commitment from a founder with Mastrov’s track record is not a vanity project. It is a benchmark.
