Owner/instructor Marnie Alton is the reason to take this class, an intense combination of cardio and ballet: Not only is her perfectly sculpted physique a walking billboard for barre, but she is also one of those teachers that has eyes on the back of her head, calling out adjustments from across the room and sensing precisely the moment when you are about to quit so she can come over and change your mind. Her meticulousness is tempered by her kind persona—she also seems to know every students’ name and offers hugs at the end of class. Cool feature: Colored lights in the studio change according to the intensity of the workout, adding to the high-energy vibe.
Pricing: $28 for one class, $260 for 10-class pack; $250/month for unlimited classes. New clients can get one month of unlimited classes for $99.
