At the helm of Equilibrium’s two studios is Annabelle Rosemurgy, an equestrian and former Olympic athlete whose performances required enough core strength to pull off a handstand atop her horse during competitions. In her studios, she helms a team of certified instructors that leads a host of amped up Pilates routines and RealRyder indoor cycling classes.

Forty-minute SPX classes initiate novices into the intense practice, designed to keep on incinerating calories hours after the sessions end. The studio’s bread and butter, however, are the SPX and Systeme Dynamique classes—variations on the Pilates method—that use circuit training to target extra weight in the hips and thighs and isolate muscle groups all over the body to sculpt, tone, burn fat, and increase flexibility. Even the studios' indoor cycling sessions target core muscles, strengthen the upper body, and torch calories, getting legs pumping on RealRyder bikes that allow riders to steer and lean, simulating the real cycling experience of avoiding potholes and the maneating Sarlaccs that live inside them.
