Cosmos Fitness, Atlanta

Cosmos Fitness, named one of the area’s top 10 fitness centers by the Atlanta Business Chronicle, earns its designation by building relationships between patrons and fitness experts in their locally owned and operated gyms. However, its coziness belies the scope of the facilities. Instructors lead the national exercise programs, Zumba and SilverSneakers. In Zumba classes, students shake off pounds to Latin beats, getting a rigorous cardio workout with simple salsa and rumba steps. SilverSneakers courses, meanwhile, tailor their workouts to seniors and include SilverSplash, a pool-based class where students stay afloat with kickboards, rather than by saddling a balloon seahorse.

Cosmos Fitness also powers solo workouts with extensive cardio equipment, free weights, and a team of personal trainers. The sauna and steam room flank an indoor pool where swimmers can hone their breaststroke or chat up the local mer-people. Before workouts, parents can drop their kids at the Marietta location’s childcare center, whose primary-colored decor matches its trove of rainbow-hued toys.
