Opening doors for 24 hours a day, seven days a week is an exhausting proposition for any doorman, unless he's a robot. That's why Anytime Fitness—having redirected its robot budget into tanning beds, cardio equipment with built-in TVs, and Star Trac weight machines—installed a keycard-activated security system instead. The electronic guardian keeps gym members secure while admitting them at any time of day or night for their workouts.

During daylight hours, certified instructors incinerate calories with group fitness classes. Personal trainer Chris coaches clients in one-on-one sessions, tailoring regimens to each individual's level of fitness, past injuries, or number of tentacles. To relax after workouts, staffed tanning beds stand by to bronze bodies.
