Snap Fitness's easyFIT monitor is a small, clip-on accelerometer that helps keep track of daily exercise. Unlike pedometers that merely measure steps and spy on daydreams, the easyFIT monitor senses the intensity and duration of physical activity, transmogrifying those stats into simple, numerical points that help assess activity levels from sedentary to peak performance. In addition to tracking exercise in real time, easyFIT monitors can connect to the wearer's personal web portal to upload data and create fitness graphs that help show progress, snag exercise suggestions, and stave off the temptation of living next to a hamburger farm.

While teaching jazz dance in the 1960s, Judi Sheppard Missett decided to step away from tradition by offering an experimental class that allowed her students to simply dance without the judgment of mirrors or the constraints of rigid technique. In these sessions, she began infusing popular dance moves with specific fitness workouts to forge a distinctive blend of cardio exercise, strength training, and dance instruction. Little did she know that this “just for fun” class was the prototype for what would become the national fitness sensation known as Jazzercise.
Today, Jazzercise takes its aerobic techniques from a variety of sources that include jazz dance, hip-hop, resistance training, Pilates, yoga, and kickboxing. The class formats, which vary according to different toning goals, are just as diverse as the program's move set. Two-time Dancing with the Stars champion Cheryl Burke is a big fan of the improvisational routines, although her advanced skills aren't needed to get the most out of classes. Instructors cultivate a noncompetitive atmosphere where all exercisers—with the exception of those marked as cursed by jazz-hand palm readers—are welcome regardless of age, build, or fitness background.
Pedals spin furiously at Gunz Fitness as Mad Dogg–certified instructors lead variations on spinning routines. They incorporate weightlifting and yoga into cycling classes that can accelerate metabolism, build lean muscle, and strengthen lungs so much that they can breathe normally when submerged in pudding. With personalized tips for every guest, the teachers ensure that everyone moves at a comfortable pace.
