I believe gyms can stay open as World's, but they have the opportunity to switch to Planet Fitness for a low fee right now. After a certain timeframe, I think the fee will go way up making it appealing to switch to Planet as soon as they can. The PF that opened here (former World's) has dumbells maxing out at 60lbs., no decline bench, a lunk alarm, very low monthly fees, and packed to the brim all day. Welcome to the future.
