With two locations, long hours, and a bounty of equipment, Emerald City Athletic Club helps its members get in shape, whatever their workout of choice. Gym floors lined with regiments of Precor and Nautilus machines let members work every muscle in their bodies, and the class studios' high-tech sound systems energize Zumba, salsa dancing, and kickboxing sessions and keep stationary cycles from tearing around the room in loneliness each night. Free weights and intricate weight machines hold down the floor of a spacious weight room, where muscle sculptors work up a sweat before winding down in a dry sauna, Turkish steam bath, and hot tub. At the Everett location, an Olympic-style pool, a basketball court, and racquetball and handball courts offer even more variety.
