Planet Fitness's Explosive Growth Is A Good Thing For Competing Gyms

If you pulled on your cross trainers and bounced into a fitness club in the last quarter, there's a good chance it was a Planet Fitness—the high-value, low-price (HVLP) chain with over 1,300 locations.

Using foot traffic analysis pulled from its Foursquare City Guide and Swarm apps, Foursquare found that nearly 25% of gym-goers went to a Planet Fitness in the second quarter of 2017. In other words, of all the people who entered a gym during that time period, a quarter of them walked into a Planet Fitness at some point.
