Fresh Fitness and Dance, Seattle

If working out is fun, people will keep doing it. That's the philosophy behind Fresh Fitness and Dance in Wallingford, where small group dance and fitness classes are offered seven days a week, from morning until night. At this spacious, mirror-lined studio, energetic and certified instructors lead Zumba, Pilates, P90X, and cardio kickboxing sessions, among a slew of other high-energy dance classes. After class, the studio's infrared sauna uses gentle heat and invisible spectrum light to help with detoxification and weight loss.
