The skinny: The fitness industry loves a mash-up, taking elements from different regimens and putting them in a new workout. Ballet-based barre has been one of the fastest-growing crazes, with popular workouts including Pure Barre, Ballet and Body, the Bar Method and Physique 57—and it’s the latest to get the hybrid treatment at gyms across New York. Core Fusion Barre+Cardio at Exhale combines slow-burn core work with ballet principles to strengthen and lengthen muscles without adding bulk. Flywheel’s faster-paced version, FlyBarre, is a total-body workout, complete with nightclub-style music. Those who prefer their sweat of the dripping variety should opt for Figure 4 Fahrenheit at Pure Yoga, where you can barre all at a high temperature (105 degrees, yikes), which enables a deeper stretch.
