The gym market
Independent gyms compete directly against low-cost franchise chains (Planet Fitness, Anytime Fitness, Crunch), and the two operate on almost opposite economics — franchise locations follow brand playbooks while independents differentiate on community, specialty training, or niche programming. An owner or general manager typically controls both membership pricing and vendor relationships at the location level.
Ontario holds 0.0% of the 129,380 gym businesses MapLeads tracks nationwide; within CA, Los Angeles leads the vertical at 857.
