During the day or night, on a holiday or a plain old Tuesday, Anytime Fitness is always open. Once they register, members get a key to the gym’s secured entryway, which means they have 24-hour-a-day, 365-days-a-year access to any of the club’s nearly 1,800 locations all over the globe. Personal trainers staff each location, where they lead customized one-on-one training sessions or provide quick and simple tips for using the gym’s high-quality cardio and strength-training equipment. The roster of group classes includes kickboxing and boot camp to whip bodies into shape in a fun and supportive environment. After a sweat session, members can head to the locker room for a shower or catch up on their stories on one of the treadmills equipped with a personal TV. Exercisers can also accentuate their hard-earned musculature with a tanning session or two, since access to beds is either added onto their membership for an additional fee or billed on a pay-per-use basis.
