Gym chain Planet Fitness continues to surge in popularity in the United States. The secret sauce of the company has been its low-cost gym membership and inviting workout environments. Now, the company is starting to take its show on the road, with an entry into Canada in 2015. But, Planet Fitness’ rise to the top in the highly fragmented gym industry sheds light on two huge trends in the U.S. The first is the growing number of fast food chains, which are packing on the pounds on a nation that is battling with robust levels of obesity. Second, the uprooting of physical retail due to more mobile consumption, as seen hundreds of store closures, continues to afford Planet Fitness access to attractive real estate assets. Brian Sozzi talks with Planet Fitness CEO Chris Rondeau to discuss.
