Life in Synergy makes it easy to get your body (and mind) in check. Classes are just $15 a piece (or ten for $100), and there’s no membership fee. From yoga sculpt to vinyasa dance, lessons in the Water & Wind studio are calm and soothing, while the Fire & Earth room runs heart-racing options like Zumba; Tae Kwan Do conditioning; and our fave, Japanimation (for that Pussycat Doll swagger).
