Refine Method

In-the-know fitnessphiles who envy ballerina bodies have long been eschewing barre classes and heading instead to Refine Method, founded by former New York City Ballet dancer Brynn Jinnett. After debuting on the Upper East Side, Refine opened its second location on the other side of the park in 2012. Refine is perfect for West Siders who want their fix of intervals and circuits, many of which make use of Refine's unique pulley system, designed to target every muscle group three-dimensionally, between cardio bursts on the rubber floor that may leave you gasping for air. In addition to correcting your form, the deadly serious but super friendly instructors, who will remember your name by your second session, won't let you slack as they carefully work with your fitness level, no matter how long you've been working out. Price: First class $34, starter four-pack class $99.
