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.
